Calibration Issues - Githubissues

aximuseng commented 3 years ago

I was trying to get this up and running - my calibration images will only trigger when something slow goes by. For example these people walking by. I will be able to go out an actual measure the distances etc but for now I think I need a proper calibration image.

Is there an initial default setting I need to change to trigger this for calibration and testing?

That is the calibration image. It would appear the camera is too close. Faster objects will likely go through the speed rectangle (red) without triggering.

You might try another location. Also it would appear you are not on the default stream size so you might want to revert to the default config.py to start.

I have the default config file and I can't really move the camera. I have set the camera to the smaller frame size. Here is what I get when a car drives by (not triggered a calibration image):

I lowered the track counter to 4 and got a car to trigger:

calib-20210609-1729500

aximuseng commented 3 years ago

Also to clarify this is from an IP camera.

pageauc commented 3 years ago

I would decrease track_counter = 5

and increase x_diff_max = 30 increase if you get a lot of OUT log entries. X-diff is the maximum distance away in pixels from the previous track point. Since you are close you can increase. Adjust as required but not too high to avoid problems. Contours can move to a different part of the vehicle due to lighting, shapes on object Etc.

Give that a try and see how that works.

We were on the same page - settings I tweaked:

track_counter = 4
event_timeout = 1.0
x_diff_max = 60
cal_obj_px_L2R = 240      # L2R Moving Objects, Length of a calibration object in pixels
cal_obj_mm_L2R = 7920  # L2R Moving Objects, Length of the calibration object in millimetres

cal_obj_px_R2L = 240      # R2L Moving Objects, Length of a calibration object in pixels
cal_obj_mm_R2L = 7920  # R2L Moving Objects, Length of the calibration object in millimetres

Walked out an laid down some chalkiness. The red box is roughly 26'. Enough accuracy for now.

So here is me driving by @ 40 km/hr

I also drove by the other way right after and that didn't even trigger. The one above is a double.

Set track timeout to 0.5 sec. This will avoid tracking object twice per comment in config.py
