Multiple detection - different speed

Hello Claude, I have a strange problem, some vehicles are measured twice, at different measuring points as it seems. Unfortunately, the speeds differ again and again and I do not know exactly what I can still check. Maybe a setting in the motion or open cv settings?

SPEED_MPH = False  
track_counter = 10
MIN_AREA = 150
show_out_range = True
x_diff_max = 30   
x_diff_min = 1  
x_buf_adjust = 10
track_timeout = 0.0  
event_timeout = 0.3
max_speed_over = 0 

BLUR_SIZE = 10
THRESHOLD_SENSITIVITY = 20    

If you need more details, let me know - its reproducible.

I use a Raspberry Pi 3 Model B Rev 1.2

Thank you in advance Andreas

Should not be picking up grass moving since it uses motion tracking but is possible depending on the motion sequence. In config.py there is a Motion Setting MIN_AREA = 100 This is 100 square pixels so quite a small area. You can increase this but not too big since it may prevent tracking of some objects. Do some trial and error to get a setting that works best.

So I am still waiting to see how this goes. We aren’t getting a lot of vehicle traffic. But it is constantly picking up the tall grass blowing in the wind. Is there a way to make it only look for larger objects? Or would that take some more development?
