Description

self.depth_channels = int( (self.dbound[1] - self.dbound[0]) / self.dbound[2])

  1. why is depth channels setting 'd_bound': [2.0, 58.0, 0.5] to compute channels is 112 ?
  2. https://github.com/Megvii-BaseDetection/BEVDepth/blob/main/exps/bev_depth_lss_r50_256x704_128x128_24e.py#L271 Why to multiply 3.0 depth_loss?

Research direction

Start with the self.depth_channels calculation shown in the issue and the linked line 271 in exps/bev_depth_lss_r50_256x704_128x128_24e.py. Trace the d_bound values and depth-loss configuration, then document why they produce 112 channels and why the loss is multiplied by 3.0.
