Summary:The invention relates to a classification and distance measurement method and system for a cone barrel, and the method comprises the following steps: firstly, a laser point cloud is mapped into a two-dimensional image through the mapping relation between the laser point cloud and a camera image; secondly, cone buckets in the image are positioned and classified according to an algorithm; then, the laser point clouds subjected to preliminary screening and frame selection are clustered through an Euclidean distance clustering algorithm, and non-conical barrel point clouds are further removed; and finally, according to the types of the bounding boxes, the laser point clouds in the corresponding bounding boxes are subjected to color assignment according to RGB values corresponding to the types of the bounding boxes, cone barrel point clouds of different colors are obtained, and high-quality cone barrel laser points clustered in the bounding boxes of the different cone barrels can be used for calculating the distan
