This video shows Chris Wood go though the main functions of the FLIR E8 thermal imaging camera to give a great introduction and overview on how to use and get the best out of the camera. If you have purchased or are thinking of buying a FLIR C2 camera and would like to know about all its functions, take a look at our tutorial video featuring our surveyor Chris Wood.Infrared energy is part of the electromagnetic spectrum.

It is around us all the time, but it is invisible to the naked eye, except for a tiny slice in the middle called visible light. Our eyes see light that is reflected off a surface. It reflects at different wave lengths and this makes the colour differences that we see. Thermal energy can be given off — emitted — or reflected.

Not only will most of the thermal energy you see from a drone be emitted or reflectedit can also be both at the same time. When talking about how effectively an object gives off its thermal energy, we talk about its emissivity. Different objects give off thermal energy differently, based on various factors, such as what it is made of and its surface condition.

When two objects are close together in temperature, but have different emissivity, they can appear different to a thermal camera. Different colour schemes are used to depict different thermal images.

These vivid colours or greyscale details represent a very specific and very large data set. Understanding what they represent and how best to use them in the field allows users to detect suspects, targets and objects of interest.

White Hot displays warmer objects in white and cooler objects in black. Greyscale palettes offer simplicity for scenes with a wide temperature span and generate images with realistic details.

The versatility of White Hot makes it appealing for use in shifting landscapes and urban areas. The Sepia palette applies a warm, golden hue to the White Hot palette for reduced eye and mental fatigue. It is ideal for instances of prolonged thermal surveillance or scouting. Using different colours to display minute temperature differences, Rainbow HC is best suited for scenes with minimal heat change. Focusing on an area with similar heat energy allows the Rainbow HC to detect objects and slight temperature changes.

Black Hot is the inverted version of White Hot, displaying warmer objects as black and cooler objects as white. A favorite among law enforcement and hunters, Black Hot displays body heat in a clear, lifelike image.

Identifying warm objects with a golden colour and colder objects with shades of blue, the Arctic palette mixes the simple coloring of Ironbow with the low-contrast performance of Rainbow HC. Differing colours quickly detect heat sources while darker shading picks out slight temperature changes. A general-purpose palette that quickly identifies thermal anomalies and body heat, Ironbow uses colour to show heat distribution and subtle details.

Hot objects are shown in lighter, warm colours while colder objects are dark, cool colours. When it comes to selecting and interpreting thermal images, there is not necessarily a right or wrong answer. One suggestion is that White Hot and Dark Hot are your go-to palettes when the detection of small, faint heat differences is your primary goal, or when operating in challenging environments with lots of heat and humidity.

On the other hand, the likes of Ironbow are good all-round colour palettes, especially when looking at roofs, solar panels or outdoor electronic equipment, while Arctic is designed to enhance contrasting colours. According to the FLIR website, thermal imagers are most effective in the hands of users who can quickly interpret a scene, and hands-on experience with each available palette is the best way to make confident, split-second decisions when it truly matters.

Isotherms are a type of colour palette. They highlight certain temperature ranges so they stand out to the operator. When trying to detect subtle heat differences in these types of conditions, the most effective palettes to use are Black Hot and White Hot.

The higher the resolution of the camera, then the more pixels you have, which in turn gives greater image detail. However, with a smaller lensethe higher resolution will have a significantly wider field of view FOVso the pixels will be spread over a wider ground footprint, which can result in a decrease in your detection range.

The trick is to finding the right balance between image detail, ground coverage and magnification. The first scenario compares 9mm lenses, but with different resolutions and highly-contrasting FOVs.Thermal cameras can deliver where visible conventional cameras fail, but they come with significant tradeoffs which must be considered.

In this tutorial, we cover these topics, including:. No matter how high resolutions may go, traditional surveillance cameras will always have performance issues when light levels are low or vision is obscured.

10 Best Infrared Thermal Camera Apps (Android/IPhone) 2020

Since they do not need light, instead using infrared radiation to produce images, thermal cameras can fit in applications where others fail. This sample is from our thermal vs. This tutorial only reviews uncooled thermal cameras, the most commonly used choice in surveillance.

However, cooled imagers can see far farther but cost much more. See FLIR's uncooled vs cooled note [link no longer available] for a overview of cooled thermal. Since they do not see visible light, thermal cameras do not reproduce color, and fine details between areas or objects of similar temperature are lost. Compounding this, their lower resolution results in lower pixel density, further reducing detail.

At close ranges, especially with VGA cameras, some details may be discernible, such as clothing types, or a known subject may be recognizable, but these are generally outlying cases, not the norm.

These images are examples of thermal cameras at short and long ranges. Note the details which may be made out on the subject in the near image hat, vest, boots, glasses, etc. Unlike visible cameras, where resolution may outweigh other factors in imaging, contrast is the most important aspect affecting thermal images' usability.

For example, if we look at these images from our tests of thermal cameras while snowing, we can see the reduction in contrast from first to last results in less visibility of distant objects: Get Notified of Video Surveillance Breaking News Sign Up Get Notified of Video Surveillance Breaking News Sign Up. Unlike visible light cameras, where the megapixel race continues, thermal camera resolution has remained fairly steady, with QVGA resolution, xstill most common, though some sensor manufacturers offer a slightly higher resolution, x Previously, resolutions below QVGA were common, such as xbut these are phasing out, with manufacturers discontinuing these models as higher resolution sensor costs come down.

Unlike visible cameras, where CS mounts and varifocal lenses are ubiquitous, thermal cameras almost always use fixed focal length lenses. Thermal camera lenses are generally machined from germaniumas glass is not thermally transparent and actually blocks thermal cameras. This is one reason thermal camera price increases as lens size goes up, as larger pieces of germanium are more difficult to source and machine.

Thermal speed dome cameras have started to become more common, with FLIRDRS [link no longer available], and Bosch [link no longer available] all offering models in this form factor. Digital zoom is perhaps more useful in thermal imaging than visible. Because the camera is only providing detection level video, often times at long ranges, a warm intruder may only be a few pixels on screen. The ability to digitally zoom the camera on this area of interest does not provide additional detail, but by simply enlarging the pixels, the subject may be easier to see.

Because they provide a higher-contrast image in varying conditions, thermal cameras are often preferred for analytics. Especially in low light scenes, when a visible camera may produce heavy noise due to increased gain, thermal cameras can be more effective.


Specifically, thermal eliminates shadows and headlights, two common problems for conventional cameras. However, thermal cameras may still be affected by moving tree branches and blowing leaves, two common challenges for analytics, as these objects still generate heat, changing the image as they move. Because of their ability to detect object temperature, thermal cameras may be used for specialized analytics which visible cameras cannot, alarming when temperatures exceed pre-set thresholds.

Compared to visible cameras, there are only a small number of thermal camera providers. Likely the most common manufacturer is FLIRwho sold only thermal cameras until their recent acquisition of Lorex and Digimerge. Other common names such as AxisBoschand Pelco offer multiple models, with specialist manufacturers such as DRS and Vumii mainly selling thermal cameras only.

Thermal cameras are considerably more expensive than conventional cameras. High-end PTZ cameras cost well beyond this, from tens of thousands of dollars through six figures.A few years ago, FLIR unleashed a new line of handheld thermal imagers upon the world. In a manufacturing triumph, the cheapest of these thermal imaging cameras contained the same circuitry as the one that cost six times as much.

Much hacking ensued. Once FLIR figured out the people who would be most likely to own a thermal imaging camera can figure out how to upload firmware, the party was over.

We first saw it about a year agoand the results were impressive. This thermal camera is built around the FLIR Lepton sensor, providing thermal images with a resolution of 60 by 80 pixels. These thermal images were combined with a VGA resolution camera to produce the very cool enhanced imagery the commercial unit will get you.

Well the difference is that he is referring to a complete camera and you are referring to the sensor made by the same company, which can be programmed and used in different ways.

Hope this clears the misunderstanding for you. There is a Linux driver as well somewhere on the eevblog forum. This is a very nice project from the standpoint of being a true open hardware FOSS project which I applaud. Especially considering it is was homework assignment! Complete schematics, design files for the board, full firmware, etc. I am just a single student who made this project in his free time, so I can not compete with big companies like FLIR or Seek with hundreds of engineers and a big budget.

The added value of this project is certainly the software part. The open-source firmware has a lot of nice features and you can control it over a touch interface. The memory is replaceable and the device can be connected to a PC or Pi for live thermal streaming. I put a lot of time and effort in this project and hope you do not only judge about it by reading the title. It may not be the cheapest solution in the meantime, but for that price, you can make your own nice thermal imager, and you can adapt it to your own needs at any time.

I think people only have an issue with the clickbait title of this HaD article rather than anything about your project. Yes, I totally understand that.

I did not choose the title, but I am happy the project is at Hackaday at all, so interested people can find it. Max, I completed your build a couple months ago with a gen three Lepton module. I have to say, I love it! The only feature that Flir has your build beat on is their proprietary MXQ or whatever imaging, which outlines objects in the image. Aside from that, I am extremely impressed and express my gratitude that you took the time to detail building the project.

As much as I would like to be able to afford an Opgal camera and have the resolution to see the individual studs hidden in my walls, your camera suffices for my needs and is definitely a better alternative to the Flir One itself. Again, thanks for all the time you put into sharing this for us. No worries. I saw many readers ranting about the sensational headlines of this website, But it probably has a direct financial impact on the website through traffic increase and ad revenue, so probably the administrators of this website keep their head buried in the mud….Are you new to thermography or perhaps need a quick refresher on the basics of infrared?

Thermal cameras are becoming cheaper and easier to use, which means they're more documented and accessible for hobbyists. In this Instructable, I'll provide an introduction to the physics behind thermography and few basic sensors that you can use in your next electronic project. Whether you want to give your robot a sense of temperature without touch, or want to find the source of a drafty window, thermography has a lot of practical uses.

Let's jump in! Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson.

Before we dive into using thermal imaging sensors, let's define a few terms and go over the physics behind the cameras to better understand what we are actually doing. I'll do my best to reasonably explain the terms and concepts mentioned. A thermal image thermogram is a digital representation of a scene and a measure of the thermal radiation emitted by the pictured objects.

Thermal images are captured via thermographic cameras, which are devices capable of sensing this radiation in the form of infrared light. A thermal image allows us to remotely sense the temperature of an object or at least accurately tell its temperature relative to its environment. This is useful as it allows us to essentially "see" in the dark as well as perceive the temperatures of many objects remotely.

This property is referred to as blackbody radiation. Around room temperature, most objects emit this radiation at infrared wavelengths. As their temperature increases, objects begin to emit light in the visible spectrum, beginning with a dim red glow before reaching a white hot which means it's covering most of the visible spectrum and eventually releasing most of that energy in ultraviolet wavelengths and beyond.

Infrared light, or IRconsists of the long wavelengths of light just beyond our visual perception of nearer red wavelengths in the visible spectrum. All electromagnetic radiation carries energy, but infrared light is more readily absorbed by matter, which increases its kinetic energy, therefore increasing its temperature.

thermal imaging tutorial

Since all matter is emitting IR light as a result of blackbody radiation and is a function of its temperature, being able to accurately sense the IR radiation can allow us to create a thermal image. Now that we know we want to detect long IR wavelengths to get a sense of an objects temperature, how do we actually detect it?

With sensors, of course! In this case, we'll talk about bolometers, since these are the types of sensors in the cameras we'll be discussing. In a basic sense, a bolometer is a simple sensor that absorbs thermal radiation, and changes resistance as a result. This change in resistance can be electrically measured, and the incident radiation which should be a function of the object's temperature can be determined.

A bolometer is a large thing, so in this case, the small array of sensors in the cameras are microbolometers. So, with an array of bolometers, we've got the basic means of detecting IR radiation from an object, which, as part of the thermal radiation as a function of the objects temperature, means we can begin to depict the thermal scene on our own terms.

Thermal cameras need to be aware of a few properties in order to work properly. What are the thermal properties of the thing we are trying to measure?If yes, so you are in the right place. Thermal imaging is not so familiar technique but, it is really effective.

It is used to see the heat bodies present in the dark. Thermal images are the kind of images which you cannot see in the dark as it is only viewed in certain colours. There are many kinds of IP-cameras used for thermal pictures but, now apps are trending more than the camera as it is free of cost.

Thermal Camera Simulated is a newly launched app which has various extraordinary features. Launched on February 16,it is a real-time thermal camera effect that simulates an infrared camera.
