generate_depth_map issue problem

[YangJae96]

Hello. I am trying to convert a disparity map to Point Cloud using your source.
But here I have a problem first in RealDepth.py def " generate_depth_map".
Could you tell me what the value of these are in generate_dept_map function?
x = np.array([5, 32, 50, 100, 200])
y = np.array([9, 2, 1.5, 1, 0])
coeff = np.polyfit(x, y, 3)
height_a = 0.9
width_a = 1.2
depth_a = 1.5
height_b = 0.5
width_b = 0.67
depth_b = 0.75

Do those value come from your own image??
I am trying to use my image and my disparity image.
Can you tell me how to change those values from my image?
