Abstract:
The present application discloses a method and device of labeling laser point cloud. The method comprises: receiving data of a laser point cloud; constructing a 3D scene and establishing a 3D coordinate system corresponding to the 3D scene; converting a coordinate of each laser point in the laser point cloud into a 3D coordinate in the 3D coordinate system; mapping laser points included in the laser point cloud into the 3D scene respectively according to the 3D coordinate of the laser points; labeling the laser points in the 3D scene.

Claim (Index 4):
The method according to  claim 3 , determining the type to which the laser point in the 3D scene belongs comprises:\n determining the types to which the laser points in the 3D scene belongs according to a first mode or a second mode: the first mode: generating a 3D selecting box according to first size information set by a user; moving a position of the 3D selecting box in the 3D scene according to a first moving instruction input by the user; when receiving a labeling instruction carrying a target type, taking laser points currently falling within the 3D selecting box as target laser points and taking the target type in the labeling instruction as a type to which the target laser points belong; the second mode: generating a ray by taking the position of a camera of the at least one camera as a start point and taking a screen position point selected by the user as an end point; taking laser points meeting the following conditions as target laser points: a distance of a laser point from the start point is between a first distance threshold and a second distance threshold, and a vertical distance of the laser point from the ray is less than or equal to a third distance threshold; when receiving a labeling instruction carrying a target type, taking the target type in the labeling instruction as a type to which the target laser points belong.
