4 years ago Simply using the Z won't give the true depth value. That's why we calculate the euclidean distance between the camera and the point using: np.sqrt(x ** 2 + y ** 2 + z ** 2)

In image.py, I find “img[r, c] = np.sqrt(x 2 + y 2 + z 2)” . As far as I know, the depth value in the pcd file should be "z“. In the final version, does the extraction of depth information not use ”z“ but ”sqrt(x 2 + y 2 + z 2)“? And why? Hope you can answer, thank you!
