Abstract

The invention provides an automatic labeling method and device for a target object. The automatic labeling method comprises the steps of determining a first labeling box according to a first projection of a target object on a first projection plane in first point cloud data, obtaining second point cloud data in the first labeling box, determining a second labeling box and a third labeling box according to the second projection of the target object on the second projection plane and the third projection of the target object on the third projection plane in the second point cloud data, determining a minimum bounding box coordinate of the target object according to the first labeling box, the second labeling box and the third labeling box, and displaying the minimum bounding box of the targetobject in the first point cloud data according to the minimum bounding box coordinates. According to the embodiment of the invention, the target object can be automatically labeled in the laser pointcloud without manual labeling.

Description

technical field [0001] The present disclosure relates to the technical field of automatic driving, and in particular, relates to a method and device for automatic labeling of a target object capable of automatically generating a labeling frame of a target object. Background technique [0002] In recent years, with the continuous development of autonomous driving technology, laser point cloud object recognition technology has been widely used. Laser point cloud object recognition refers to the use of laser radar (a radar system that emits laser beams to detect the position and speed of the target) to scan the laser point cloud data centered on the vehicle and identify the target object, so as to complete the vehicle's detection of obstacles. avoidance and identification. In order to make the laser point cloud object recognition process accurate, it is necessary to pre-train the recognition model used by the vehicle—by manually operating the computer to mark the target object...
