Cats and cars detected as person

[ppruneau]

Hi,

pretty sure it's a "code 18" kind of problem, but I can't manage to find the issue.

As the title of the suggestion says, Frigate detect "everything" as person, for example :

I already tried messing with threshold and min_score for the "person" filter as suggested in another discussion without success.

Here is my configuration (at least the "interesting" part of it) :

objects:
  filters:
    person:
      min_score: 0.5
      threshold: 0.78

#Cameras configuration
cameras:
  veezoom:
    ffmpeg:
      inputs:
        - path: rtsp://hidden:hidden@192.168.10.92
          roles:
            - detect
            - clip
    record:
       enabled: True
      events:
        retain:
          default: 14
        required_zones:
          - stationnement
        objects:
          - person
          - car
          - cat
    snapshots:
      enabled: True
    detect:
      width: 1920
      height: 1080
      fps: 5
    motion:
      mask:
        - 1920,0,704,0,867,415,1920,704
        - 0,1080,0,0,797,0,1031,462,423,458,337,576,398,1080
    zones:
      stationnement:
        coordinates: 930,525,579,608,530,543,472,946,638,1080,1920,1080,1920,722

Thanks in advance for your help!

I would recommend min_area for person as no person would be that small.

The model used in frigate is a demo model from google and it's heavily biased towards person. This is why https://frigate.video/plus exists

Sorry, got some stuff to take car in the last days....

Thanks for your answer, and will certainly look into frigate plus someday.

But for now I'll try the min_area and see the result. And for the fact that frigate doesn't detect my car at all, would i have to set a max_area to person or something like that?

Thanks!

I just realized your problem, you never defined objects to track. You have to add that or the events part does nothing.

objects:
  track:
    - person
    - car
    - cat

That would also explain why you were getting the other issue too.

Damn you're right! I thought that adding it to the event part was the only requirement...

Fixing it right now, gonna keep you up to date if that works. In any case, thanks! :)
