reconstruction noise(Strange noise)

Hi, sorry to bother you ! There is a lot of noise in the reconstructed object, as shown in the figure. This kind of noise is mainly on trees and columnar objects ( traffic light, pole etc ), almost white, but the color RGB is not (255,255,255). I want to ask how to eliminate this kind of noise. Is this kind of noise caused by the error of the depth map patch match calculation? In the sterefusion stage, I turn up the min_ num_pixels,and turn down stereoFusion.max_reproj_error and max_normal_error , but it can't be eliminated this noise. thanks.Look forward to your reply.
