cberry28endoscope
Live USB endoscope camera monitor on a Raspberry Pi with C-Berry28 display using OpenCV
Features
- Automatically connect to first camera
- Scale down image resolution to fit display (640x480 capture to 320x240 display)
- Exit on error (combine with autostart loop script below for use with defective USB camera cables)
Additional Information
- Dependencies:
- OpenCV 4 (tested with package extra/opencv 4.3.0-4 on Arch Linux ARM https://archlinuxarm.org/)
- bcm2835 library http://www.airspayce.com/mikem/bcm2835/ (tested with version 1.52)
- tft.*, ST7789.* and bmp.* files are taken from C-Berry28 software package (see p. 12 of the datasheet linked below)
- To build, just use the
makecommand - Scaled image is converted to bitmap format for the display framebuffer
- 640x480 capture resolution is a tradeoff between framerate and image quality (Raspberry Pi 2B used)
- Backlight PWM value is set to 200 (max. 255)
- For autostart/-restart on boot, e.g. use a crontab entry like this:
@reboot while true; do /path/to/cberry28endoscope/endoscope; sleep 10; done
