Shadow areas in point clouds without images

[Ericshuai1]

Thank you very much for your outstanding project

In this image, there are shaded areas such as lane markings, making it easier to select points. However, in my image

There are no points in the selected point cloud that correspond to the image

Maybe you can pick up edges of windows or buildings?

Why not select pointclouds by ourselves. I selected pointclouds again after preprocesss, and it works

Pleaese note that you don't need to select points for every image. Picking 5 to 10 points through all imaged is sufficient.
