It is based around the STM32F4, a powerful ARM Cortex-M MCU by ST Microelectronics, and its As it happens, the FLIR Lepton is an excellent little module for the price and Pure Engineering has done a bang up job spinning the breakout board and.The PureThermal 1, PureThermal 2, and PureThermal Mini series of boards areĪre an embedded development platform for the FLIR Lepton thermal imager, created by There are a number of differences between Sparkfun instructions and Pure Engineering instructions that I needed to sort out. The Radiometric Lepton module is extremely sensitive to electrostatic discharge (ESD). Since it isn't working as well as the Sparkfun demo, I may still be doing a number of things wrong. When inserting it into the breakout board be sure to use proper personal grounding, such as a grounding wrist strap, to prevent damage the module. To get to "raspberry_video" you first have to go to /LeptonModule-master/software, Sparkfun indicated going to "raspberry_video" directly while the Pure Engineering instructions indicate one should first go to "software" Includes: 1x FLIR Lepton 2.5 - Thermal Imaging Module 1x FLIR Lepton - Breakout Board v2. Not that important but what was important, is I never found the file Sparkfun references within the download software from Pure Engineering, “LeptonSDKEmb32PUB" and the Pure Engineering instructions never reference this file. The FLiR Dev Kit offered by SparkFun has the breakout board as well as a the Lepton longwave infrared (LWIR) imager and is available for 349.95 USD, making it easy to get everything you need to start developing your own thermal imaging projects with an Arduino, Raspberry Pi or an ARM based development tool. I then noticed the file "LeptonSDKEmb32PUB" on Sprkfun's site and downloaded it and assumed it should be unzipped to "raspberry_video". Listed below are some of the characteristics of the FLIR Lepton’s specs. After doing this it didn't seem to make any difference. The cells highlighted in blue indicate the slight differences between the two versions of the FLIR Lepton camera module. (is it possible that the file is no longer needed and the Sparkfun site isn't updated?) FLIR Lepton FLIR Lepton v2. Still very glitchy software: not able to resize, get a vertical line after awhile, the ffp freezes up, freezes up after a few hours, etc. How to get Technical Assistance from a Technical Support Moderator.Hopefully, Sparkfun guys read this and have some additional suggestions. A la Carte(ALC) Custom PCB Design Services.Microcontrollers, FPGA & Single Board Computers.Other microcontrollers and single board computers.Electromagnetic spectrum with visible light highlighted.The FLiR Dev Kit includes a breakout as well as a Lepton longwave infrared (LWIR) imager. The sensor inside the FLiR Lepton is a microbolometer array. With this kit you will be able to bring FLiRs thermal imaging. Microbolometers are made up of materials which change resistance as they’re heated up by infrared radiation. 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. Thermal imaging of this type is often used in building inspection (to detect insulation leaks), automotive inspection (to monitor cooling performance), and medical diagnosis. Also, because of its ability to produce an image without visible light, thermal imaging is ideal for night vision cameras. 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. 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! #Lepton flir sparkfun software 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?
