Hi,
- No, it's juste a vizualisation. If you want to output actual depth, you can this line here. Careful, it will be much heavier as it's uncompressed floats.
np.save(output_dir/'{}_depth.npy'.format(file_name), depth)
- The scale factor is undetermined. That's the main pain point of this work, it's not constant with the network, you need to find it each time. You could try a scale factor that works for most images, but there is no guarantee at all. The method to get it in the original paper is to compare the median of prediction with median of groundtruth. The proposed alternitve method here is to compare movement magnitude prediction with Posent with groundtruth odometry, either from GPS or from integrating wheel speed.
- As said above, the depth map needs a scale factor to be computed. It's up to you how you get it since KITTI features both Lidar and odometry. Odometry is more realistic if you plan to use it on your own device where chances are that you have Lidar data

Hello, Thank you. Will definitely try it out.
