how to get depth.png in kitti

[andersonhusky]

hi! thanks for your excellent work , I have a quesion about how you get the depth.png under the /demo-kitti/depth?

Hi @andersonhusky, This is explained in section IV. System in our paper VDO-SLAM: A Visual Dynamic Object-aware
SLAM System (https://arxiv.org/pdf/2005.11052.pdf)

thans for reply @MinaHenein! I know you are using MonoDepth2 to create depth image in Monocular mode, but it seems like the depth.png under the /demo-kitti/depth is calculated from Stereo mode

[MinaHenein]

@andersonhusky Yes, correct.
From our paper:

The input to the system is stereo or RGB-D images. For stereo images, as a first step, we extract depth information by applying the stereo depth estimation method described in [62] to generate depth maps and the resulting data is treated as RGB-D.
