MoTrack

Uses python3 and opencv to Track Largest moving object in camera view (picamera2 libcam, picamera legacy, RTSP IP cam or USB Webcam).

Introduction

This is just some demo working code to test motion tracking using python picamera2 libcam, picamera legacy Camera, rtsp IP camera or USB Webcam. On completion of a successful track an image is saved in ./media/images Optional tracking history can be displayed on images as contour center point circles or contour rectangles. Images can be viewed on web browser via provided webserver.py run in foreground or background. Program user settings are saved in the config.py file and configcam.py.

Ver 1.60 Details

This version isolates camera stream thread logic and allows easy integration into my other projects. I can now simply add two lines per below and remove previous camera code. Still supports PI legacy, Libcam, USB and RTSP IP Cameras. Configured using the CAMERA variable in configcam.py

from strmcam import strmcam   # import camera function

vs = strmcam()      # start video stream thread

# example implementation
image1 = vs.read()  # read video stream image frame into variable
vs.stop()           # Stop Camera Thread
