They correspond to the z coordinate of each pixel in camera coordinate space (not the distance to the camera optical center). camera intrinsic matrix (in pixels, constant, computed from our 1242x375 resolution and 29° fov):
[[725, 0, 620.5],
K = [ 0, 725, 187.0],
[ 0, 0, 1]]

优化模型的方法 1、深度分割联合预测 http://users.eecs.northwestern.edu/~xsh835/assets/cvpr2015_depth.pdf 2.Single RGB Image Depth and Certainty Estimation via Deep Network and Dropout 3.深度图超分辨 由于深度图一般的分辨率比输入图像小很多,需要采用超分辨率的方法增大分辨率 https://arxiv.org/pdf/1605.09546v1.pdf
目的:验证现有模型预测深度的可靠性,为是否进一步改良模型提供依据。
