摘要：

Based on the special geometry of cave targets, a method for LiDAR point cloud data rapid recognition of residents cave and natural cave has been proposed. By calculating the distance between LiDAR points and sensor position, the target can be quickly identified if there is a distance sudden change. In order to improve the accuracy of target recognition, the number threshold of sudden change points and region-wide threshold are introduced, and the recognized target contour points can be further distinguished in target front plane or inside plane.
