Problems solved by technology
There are currently two research directions for the plane extraction of 3D models. One is the method based on the point cloud model, which has large noise and high computational cost.
The other is a method based on the line segment model, but the mainstream methods are based on RANSAC and Hough transform-based extraction methods. The disadvantage of the RANSAC-based method is that there is no upper limit for the number of iterations. Although the Hough transform can solve this problem well, but There is a problem of uneven distribution of Hough space, and there are certain limitations
