... presents an analysis framework that combines image and point cloud data to improve the accuracy and efficiency of building surface defect detection. On one hand, the region of interest (ROI) is extracted from the image, and a fusion of the local binary pattern (LBP) and Otsu's method is employed to segment...

... vertical and horizontal scan resolution. Its resolution is higher than the common VLP16 (2°), so the point cloud can be captured with a more detailed geometric structure of workers and environment. In addition, the LiDAR can record point clouds at a frequency of 10 Hz, while laser scanners commonly used...
