3D Bounding Boxes not stable - they flicker all the time

[manuelschmidt]

Hey,

this is my Setup:

• i5, Nvidia GTX 1050 Ti
• Windows - running GTA V in windowed mode, 1600 x 900 and running dataset.py from VPilot repository, also on the same PC

Things that I changed compared to the original repository:

• Update natives.h to newest version and changed the coresponding names in Scenario.cpp
• Include the direction fix proposed by alexgkendall #56
• Include the Speed fix, see #60

Compared to the Youtube Video, the following things are different in my case:

• Bounding Boxes are strongly flickering and unstable

@ai-tor Did you postprocess the frames before uploading the video to stablize the bounding boxes? If not, could my changes have led to this behaviour and how could I fix it?

General question: I noticed, that cars are never "detected" if another car is right in front of it. Does this mean that the creation of the bounding boxes works somewhat like "you only get what's in your direct line of sight?"? Is it based on raytracing maybe? An example for this can be found in the youtube video between 0:29 and 0:30 where the bounding box of the truck disappears for a moment.

Thanks for this great project, really enjoy trying it!

Best regards

I got a similar issue. Does anyone have any idea on this problem?

There is an occlusion check in the code. If you don't want that you have to disable it. I wonder if you can base that check on the camera rather than on the player as it currently is implemented.
