  • GROUND EXTRACTION METHOD FOR 3D POINT CLOUDS OF OUTDOOR SCENES BASED ON GAUSSIAN PROCESS REGRESSION
    Publication number: 20220051052
    Abstract: A ground extraction method for 3D point clouds of outdoor scenes based on Gaussian process regression, including: (1) obtaining the 3D point cloud of an outdoor scene, (2) building the neighborhood of the 3D point cloud, (3) calculating the covariance matrices and normal vectors of the 3D point cloud, (4) classifying the 3D point cloud according to its neighborhood shape, (5) extracting the initial ground Gs, (6) segmenting the initial ground, (7) 2D Gaussian process regression, (8) finding the neighborhood NLGk of each ground fragment LGk, and (9) extracting the final ground Ge.
