AI Technical Summary

Problems solved by technology

In related technologies, manual labeling is mainly used to label point cloud data. This labeling method is relatively inefficient and relies on the ability of naked eye recognition.
Point cloud data is often composed of multiple feature points, and the overall image is relatively abstract. In many cases, the naked eye is easy to distinguish errors or even cannot distinguish the type of objects in it.

Abstract

The invention relates to a method and device for marking objects in point cloud data. The method comprises the following steps: acquiring point cloud data and image data having a mapping relationship with the point cloud data; marking a target object in the image data; and marking the target object in the point cloud data based on the mapping relation. According to the product recommendation method and device provided by the embodiment of the invention, the object in the point cloud data can be quickly and accurately marked.

Description

technical field [0001] The present application relates to the field of unmanned driving technology, in particular to a method and device for labeling objects in point cloud data. Background technique [0002] Unmanned driving technology is an important change in transportation, and it is of great significance for both traffic safety and traffic convenience. At present, driverless technology is constantly developing, so it is just around the corner that driverless cars will replace traditional manual cars. [0003] In the process of unmanned driving, it is necessary to recognize the environment around the vehicle, which mainly includes objects such as people, vehicles, roads, and traffic facilities. In related technologies, machine learning models are mainly used to identify target objects in the surrounding environment from point cloud data. The construction of the machine learning model needs to rely on a large number of point cloud sample data marked with target objects....
