Abstract

The embodiment of the invention provides a three-dimensional information processing method and device. The method comprises the steps of obtaining target image data for a target three-dimensional object; determining target two-dimensional projection information of the target three-dimensional object in the target image data; and obtaining target three-dimensional information of the target three-dimensional object according to the target two-dimensional projection information. According to the embodiment of the invention, the optimization of three-dimensional information labeling is realized, the three-dimensional information is obtained based on the two-dimensional information of the three-dimensional object, the dependence on a laser radar is avoided, and the labeling efficiency and quality of the three-dimensional information are improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and device for processing three-dimensional information. Background technique [0002] At present, in order to obtain the three-dimensional information of objects on the road, it is usually to use laser radar to mark the three-dimensional information of the object, or directly mark the three-dimensional information by adjusting the projection of the three-dimensional object in the real picture. [0003] Due to the high cost of loading lidar, not all vehicles are equipped with lidar. The way of using lidar depends on hardware support and requires a lot of manpower. The method of marking by adjusting the projection of three-dimensional objects requires manual Adjust the projection to completely coincide, the manual efficiency is low and the quality of labeling cannot be guaranteed. Contents of the invention [0004] In view of the above problems, a method and device for p...
