About depth map

Hi! Could you tell me the unit of the values stored in the depth maps provided in the dataset? Is it millimeters?

They are saved as 16 bit PNGs. I believe the correct way to open them as meters is the following:

data = Image.open(path_to_depth_png)
depth_map = np.array(data, dtype=np.float32) / 256.0
