Custom model gives bad bounding boxes #36

Greetings!

I tried running this project with my custom model and it seems to work somewhat fine, it detects the objects (2 classes) but it does not show bounding boxes on my mobile.

The reason is that it gives irrealistic width, height values for the object which cannot be seen on the mobile screen(2220x1080) as seen in the picture below:

The original model seems to work fine:

This is the part where I added the debug messages in PhoneARCamera:

Another thing that bugs me is that the position values are negative with my custom model but it still places the anchor to the object in real life, so it can certainly detect it, but something is off. Any idea why this might be?

Have you tried checking your custom anchors that you generated and correctly importing these for inference?
