![]() Any questions took weeks of struggling to get an answer. One of my first tasks at my current job was to integrate a FLIR thermal camera with an existing machine. Posted in hardware Tagged diy flir camera, Flir lepton, tcam-mini Post navigationįLIR support is atrocious. Along with tweaking the ESP32 firmware, there is still a lot that can be done with the TCam-Mini, but it sure looks like a fun project to tinker with if one is into Leptons. For this he repurposed an old in-ear thermometer calibration device. Recently has also begun to further characterize these Lepton sensors, in order to see whether their accuracy can be improved from the rated +/- 5-10 ☌. Being able to load the radiometric data directly into a desktop application for processing makes it a closer match to the professional thermal cameras which states that he’d like to get as close to in terms of features as possible. Compared to the aforementioned FLIR One Pro, there’s a definite benefit in having a more portable unit that is not reliant on a smartphone and accompanying FLIR app. Not cheap, but quite a steal relative to e.g. The project is available on GitHub, as well as as a GroupGets crowd-funding campaign, where $50 gets one a TCam-Mini board, minus the $199 Lepton 3.5 sensor. Using the 160×120 pixel FLIR Lepton 3.5 thermal sensor, and combining it with a custom PCB and ESP32 module for wireless, he created a wireless thermal camera called the TCam-Mini along with accompanying software that can display the radiometric data. While the ultimate goal is to create a stand-alone solution, with its own screen, storage and processing, the TCam-Mini is an interesting platform. Spend some time just playing with the camera to see where you might find uses for it.With how expensive thermal cameras are, why not build your own? This is the goal with which set out a while ago, covering the project in great detail. Thermography has hundreds of applications. The example in this tutorial uses the code from this repository. ![]() Lepton Module GitHub Repo - Library, Example Code, & Design Files.Mike's Electric Stuff: Reverse-Engineering the FLiR Lepton(R).Now that you're successfully retrieving LWIR images from the Lepton module, you can dig into the example code and apply it to your own project!įor more information, check out the resources below: In fact, what are we waiting for? Let me give you the tour. Imagine using something like OpenCV to track, not just color centroids, but heat centroids! That’s right, you could be building heat-seeking robots right in your own home! ![]() When it comes to robotics, thermal cameras are especially useful heat detectors because the image that they produce (by virtue of being, well, an image) can be processed using the same techniques and software as visible light images. Also, because of its ability to produce an image without visible light, thermal imaging is ideal for night vision cameras. Thermal imaging of this type is often used in building inspection (to detect insulation leaks), automotive inspection (to monitor cooling performance), and medical diagnosis. By measuring this resistance, you can determine the temperature of the object that emitted the radiation and create a false-color image that encodes that data. ![]() Microbolometers are made up of materials which change resistance as they’re heated up by infrared radiation. The sensor inside the FLiR Lepton is a microbolometer array. Electromagnetic spectrum with visible light highlighted. ![]()
