there is some confusion because in config is
IMAGE_VIEW_FT = 72 # Set the width in feet for the road width that the camera width sees

But mostly it is described as
Readme.md:* Use formula below to calculate a value for IMG_VIEW_FT variable

Hi @pageauc,

you compared your script with this one https://github.com/gregtinkers/carspeed.py but does your script analyze the direction too? I tried yours but get strange results if the vehicle moves from LTR, RTL works good - another point is the distance from the vehicles from LTR, we would need a diffrent value for image view ft would differ 1 to 3 meters. Maybe the distance is too short? Got only 13,5 meter.

best regards

speed2.py at https://github.com/pageauc/motion-track/tree/master/speed-track-2 now crops the video stream image2 to a predefined motion area rectangle and sends smaller array to opencv for greyscale motion contour processing. This means only the smaller cropped image array needs to be searched for motion contours thus increasing processing speed. Also added and reorganized config.py variables allowing for better control of image fonts, opencv gui window font size Etc.

The opencv gui window display includes the cropped rectangle window. With video streaming, threading and cropping the speed is quite impressive considering the original code ran around 12-15 fps on a single core in SSH terminal mode. Now it runs at approx 87 fps on a RPI B with B+ quadcore running well over 200 fps and RPI3 with V2 camera reporting well over 300 fps. Code should be python3 as well as python2 compatible although I have not tested under python3 due to the need to compile opencv for python3. Have run this code under python2 for quite a while and it seems pretty stable as long as the video FPS is kept reasonable otherwise threading may fail. Increasing value too much can actually slow processing as well. The V2 camera module seems to accept higher values at the same video image size. If you run 2.08 under python3 please drop me a line to let me know if it runs OK or if there are issues.
Thanks Claude ...

Thanks for all the work on this project. I just wanted to give it a try but first had to

apt-get install fonts-freefont-ttf

before the calibration images were saved. Otherwise, the program crashed.
