how to visualize the disparity map

[lraxue]

Could you please tell me how to visualize the 1-channel disparity map as 3-channel color image?

@lraxue Sorry for the late reply! There are different ways to do it in Python (e.g. matplotlib / OpenCV)
If you want to visualize it via matplotlib, here is the way I usually do.

from matplotlib import pyplot as plt
plt.imshow(depth, cmap="plasma")
plt.show()

For cmap, there are many options, please refer to here:

Hope it helps!
