So after some days with irregular results, I found my error. I don't get that I should calibrate with the detected size (green frame) and not with the real car size. As I have quite different size of the detected area/part It was hard to say the size correct.
So I used the area I want to use for detection 220px with are 4900mm - as R2L and L2R is the same distance (small street almost one lane) I think this would not make much differences.
I get now maybe 40-50% correct results or at least results that I would think could be correct. But still a lot of cars drive here above 300km/h :)
Hi
I used this tool currently in a docker testing envoirnment with version 11.22 (see #155 ).
My camera ist almost 90 degree to the street and in around 10m distance. I use a Reolink 810 with RTSP, the size ist 640x360 which not fit to any of the plugins. The framerate ist 15 fps
Calibration ..... cal_obj_px_L2R=160 px cal_obj_mm_L2R=4700 mm speed_conv_L2R=0.10575 cal_obj_px_R2L=150 px cal_obj_mm_R2L=4700 mm speed_conv_R2L=0.11280 (Change Settings in /root/speed-camera/config.py) Speed Trigger ...

Size=640x368 px px_to_kph_L2R=0.105750 px_to_kph_R2L=0.112800 speed_units=kph CAM_LOCATION= None
As you see I set the motion track area to a 320x125px area. Cars are usually within 140-170px - I set 160px I don't touch the cal_obj_mm_L2R / cal_obj_mm_L2R yet I I think this should work out.
The results I get are > 150 km/h up to 600-700 km/h if it save something or it simply I dont get any result. Some delivery guy was tracked with >80km/h walking speed ...
Here some Log maybe I overseen something. speedcam_log_20231128.log
Here on the street are 30 km/h allowed and I guess it should not be over 50 km/h but by this huge difference I wonder where I have done the mistake in the settings
Thanks :)
