This directory contains all of the files you need to compile the example code. Now cd into the unzipped folder “ LeptonModule-master” and the directory “ …/raspberrypi_video”.

#Lepton camera module download

You can download the file to whatever directory you like, then cd to that directory in Terminal, and unzip it using the following command: For most people, it’s just as easy to browse to the above link, and click “Download ZIP”. If you’re familiar with git, you can do this from the command line. Once installation is complete, go to the Pure Engineering GitHub repo and retrieve the …/software/raspberrypi_videodirectory.

#Lepton camera module install

Make sure that the Pi has an Internet connection, and run the following command to install the QT dev tools:

#Lepton camera module code

Pure Engineering’s example code is a QT application so we’ll need to get that dependency installed before we can compile it. Go ahead and do it so that the changes we just made will stick. When you exit raspi-config, it will ask if you want to reboot. After you’ve completed the SPI steps, do the same thing for I2C. Select SPI and follow the instructions on the following screens. Having a hard time seeing the circuit? Click on the image for a closer look. You should be presented with the following screen as shown below. Luckily, Raspbian makes this easy to do by including a utility called raspi-config. Our first matter of business will be enabling the Pi’s SPI and I2C interfaces. Boot it up, and open the Terminal program. In fact, what are we waiting for? Let me give you the tour…Īs I mentioned earlier, you’ll want to have the Raspbian OS installed on your Raspberry Pi. 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. This is known as the infrared spectrum, and it accounts for most of the thermal radiation emitted by objects near room temperature.Įlectromagnetic spectrum with visible light highlighted.

While most imaging sensors detect radiation in the visible spectrum (wavelengths from 380 to 700 nanometers), long wave infrared sensors detect radiation from 900 to 14,000 nanometers. Input Supply Voltage: 2.8 V, 1.2 V, 2.5 V to 3.Electromagnetic radiation is all around (and within, and throughout) us and is comprised of everything from gamma radiation on the high frequency end to radio waves on the low frequency end.Sensor Technology: Uncooled VOx microbolometer.Non-Uniformity Correction (NUC): Automatic with shutter.Image Optimization: Factory configured and fully automated.Array format: 80 × 60, progressive scan.Optimum Temperature Range: -10☌ to +80☌.Non-Operating Temperature Range: -40 ☌ to +80 ☌.Mechanical Interface: 32–pin socket interface to standard Molex® socket.Package Dimensions - Socket Version (w x l x h): 11.8 x 12.7 x 7.2 mm.Control Port: CCI (I2C-like), CMOS IO Voltage Levels.Output image independent of camera temperature. Spectral Range: Longwave infrared, 8 µm to 14 µm.Scene Dynamic Range: -10-140 ☌ (high gain) up to 450☌ (low gain) typical.Radiometric Accuracy: High gain: Greater of +/- 5☌ or 5% (typical) Low gain: Greater of +/- 10☌ or 10% (typical).Output Format: User-selectable 14-bit, 8-bit (AGC applied), or 24-bit RGB (AGC and colorization applied).Input Clock: 25-MHz nominal, CMOS IO Voltage Levels.Effective Frame Rate: 8.6 Hz (commercial application exportable).The radiometric Lepton captures accurate, calibrated, and non-contact temperature data in every pixel. With a focal plane array of 80圆0 active pixels, this Lepton easily integrates into native mobile-devices and other electronics as an IR sensor or thermal image sensor.

The FLIR Lepton® 2.5 - Thermal Imaging Module is a radiometric-capable long wave infrared (LWIR) camera solution that is smaller than a dime, fits inside a smartphone, and is less expensive than traditional IR cameras.
