About Depth

[zhangchbin]

I have converted disparity to depth by depth = baseline * fx / disparity, and the depth value will be large, maybe about 500. But actually, depth can not be large. In KITTI, it will be limited in 80m. So what is the max depth in Cityscapes? Thanks

Hi, did you find a way?

maybe 500 means places with infinite depth? By the way , do you know the baseline and fx of KITTI or Cityscapes ? Many thanks if you reply

disparity precomputed disparity depth maps. To obtain the disparity values, compute for each pixel p with p > 0: d = ( float(p) - 1. ) / 256., while a value p = 0 is an invalid measurement. Warning: the images are stored as 16-bit pngs, which is non-standard and not supported by all libraries.

Actually, there are several camera information in the raw data of cityscapes.

Thanks for your reply! I found the camera information in the raw data of CityScapes. It says baseline= 0.20, focal = 2262. Where can I find the camera information of KITTI? Are they in the raw data of KITTI?

Yes, you can also find it in others' code.

Thanks! I find that the baseline is 0.54 and the focal is 721 in others' codes.

Hi, after removing the limit value, what is the max depth in Cityscapes?

My result is nearly 500m when I randomly opened one image. What about you?

this is right and Do you know why this is done?

Me too. Have you solve the problem?
