Embodiment Construction

[0049] A method, device, and storage medium for labeling point cloud data provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0050] The term "and / or" in this article is only an association relationship to describe the associated objects, indicating that there can be three kinds of relationships, for example, A and / or B, it can mean that A exists alone, A and B exist at the same time, and A and B exist independently. B these three cases.

[0051] The terms "first" and "second" in the description and drawings of the present application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of the objects.

[0052] Furthermore, references to the terms "comprising" and "having" in the description of this application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a proc...

Abstract

The invention provides a point cloud data labeling method, device and system, and relates to the technical field of computer application. The method can effectively solve the problem that the target object is inaccurately labeled when labeling is carried out only based on the point cloud data. The method comprises the following steps: acquiring initial point cloud data and two-dimensional pixel data of a first image corresponding to the initial point cloud data; meanwhile, a first selected box and a second selected box are obtained, the first selected box comprises the target object in the two-dimensional pixel data, and the second selected box comprises the target object in the initial point cloud data; and then, according to the first selected box and the second selected box, determining annotation information of the target object in the initial point cloud data. The embodiment of the invention is applied to a computer system.

Description

technical field [0001] The present application relates to the technical field of computer applications, and in particular, to a method, device and system for labeling point cloud data. Background technique [0002] With the development of intelligent measurement technology, identifying target objects in the surrounding environment has become a key technology in engineering measurement applications. In order to be able to detect the target object in the surrounding environment. Most of the existing methods directly label the point cloud data obtained by the lidar in the environment to obtain the labeling result of the point cloud data of the target object, and then identify the target object. However, this method may have the problem of inaccurate labeling of target objects only based on point cloud data. SUMMARY OF THE INVENTION [0003] The present application provides a point cloud data labeling method, device and system, which can effectively solve the problem of inac...
