In deep learning-based classification studies of complex point clouds, accuracy has been observed to decrease as the number of sampling points increases. For example, the accuracy of a network model designed for the fast extraction of point cloud-based pavement aggregate gradation follows an inverted V-shaped trend (Chen, et al., 2023).
