Spend some time just playing with the camera to see where you might find uses for it. Thermography has hundreds of applications. The example in this tutorial uses the code from this repository. HTML Datasheet: LEPTON® Engineering Datasheet. Lepton® 3.5 with Radiometry Long-Wave Infrared (LWIR) Camera Module. Lepton Module GitHub Repo - Library, Example Code, & Design Files. Order FLIR Lepton 500-0771-01 (500-0771-01-ND) at DigiKey.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. The Thermal Imaging System described in this document has at is heart a FLIR Lepton long-wave infrared (LWRI) Thermal Imaging Camera module version 2. 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. Other imaging tasks may present similar or different challenges. The purpose of this article is to explain the main challenges presented by the use of this IR camera in a typical image processing task like automated people counting. Microbolometers are made up of materials which change resistance as they’re heated up by infrared radiation. The FLIR Lepton is a low-resolution LongWave InfraRed (LWIR) camera. The sensor inside the FLiR Lepton is a microbolometer array. Common to all versions of Lepton, its size allows for integration in a variety of products, including smartphones, diagnostic tools, automobiles, Internet of Things (IoT) devices, building controls, process equipment, security systems, machine vision systems, advanced gaming devices and unmanned aerial systems.Electromagnetic spectrum with visible light highlighted. The FLIR Lepton 2.0 camera core is a long-wave infrared (LWIR) thermal imaging breakthrough in size, power consumption, and price. Lepton 3, at 160x120 resolution, delivers four times the thermal resolution as the previous Lepton generation, providing OEMs with image detail, while maintaining the package for even greater utility in commercial applications. Additionally, Lepton has been integrated into numerous third-party OEM products, such as the Cat S60, the first smartphone to feature integrated thermal imaging, the Snap-on Diagnostic Thermal Imager for automotive inspection, and the Black Hornet nano-class drone from Prox Dynamics, a company FLIR acquired in 2016.įLIR also announced that it is making FLIR Lepton 3 available to OEMs to integrate into products. Since its launch, Lepton has been integrated into more than 20 FLIR products, including multiple generations of the FLIR ONE smartphone camera attachment, the FLIR C2/C3 cameras for building professionals, the FLIR Duo camera for drones, and FLIR’s comprehensive line of Infrared Guided Measurement (IGM) test and measurement products. Lepton features many proprietary technologies, including wafer-level detector packaging, wafer-scale micro-optics, a custom application-specific integrated circuit (ASIC), and a camera package. Launched in 2014, FLIR Lepton became a longwave infrared (LWIR) thermal camera small enough for smartphone integration. FLIR announces FLIR Lepton 3 microthermal cameraĪpril 17, 2017-FLIR announced it is making FLIR Lepton 3, available to original equipment manufacturers (OEMs) for product integration.
