speed-cam.py - RPI OpenCV2 Object Speed Tracker

A Raspberry Pi Speed Camera using python, openCV, pi-camera, Video Stream

Program Description

This is a raspberry pi computer openCV2 object speed camera demo program. It is written in python and uses openCV2 to detect and track object motion. This can be vehicles or any other moving objects. It tracks the speed of the largest moving object in the camera view. The results are recorded on speed photos and in a CSV data file that can be imported to a spreadsheet or other program for additiona processing.

The program will detect motion in the field of view and use opencv to calculate the largest contour and return its x,y coordinate. Motion detection is restricted between y_upper and y_lower variables (road or area of interest). If a track is longer than track_len_trig variable then average speed will be calculated (based on IMAGE_VIEW_FT variable) and a speed photo will be taken and saved in an images folder. If log_data_to_file=True then a speed2.csv file will be created/updated with event data stored in CSV (Comma Separated Values) format. This can be imported into a spreadsheet.
