OpenMV – Better, Stronger, Faster and only $65 USD
Recent updates to the firmware for the OpenMV H7 Camera have brought some new functionality to this device, which is popular for open source neuroscience projects (e.g. Rodent Arena Tracker, or RAT: https://hackaday.io/project/162481-rodent-arena-tracker-rat). The new firmware allows for use of the popular TensorFlow library for machine learning on this MicroPython-based device. It’s small (1.5 by 1.75 inches), consumes only a max of 140 mA when processing data, has 1 MB of RAM and 2 MB of flash, and runs 64-bits computations at 4800 MHz (3.84 GB/s bandwidth). OpenMV is capable of frame differencing, color tracking, marker tracking, face detection, eye tracking, person detection (with TensorFlow Lite), and more. The project supports a very easy to use GUI, the OpenMV IDE. It’s intuitive to use, and offers a number of ready to go applications. Arduino users will feel right at home, despite the code being Python based.
