Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0031] Each data point in the 3D point cloud data usually records the three-dimensional coordinate value (x, y, z) of the point and the serial number of the point. In related technologies, when annotators label data points in 3D point cloud data, they can only label the data points one by one, which leads to slow labeling speed and low la...

Abstract

The invention discloses a method and a device for labeling an object in 3D point cloud data. The method and the device are used for solving the problem that the object in the 3D point cloud data cannot be efficiently labeled in the prior art. The method comprises the steps that a labeling device displays a frame of 3D point cloud data; receiving an input object type; receiving an input object plane parameter, and generating an object plane area in the 3D space according to the object plane parameter; projecting the generated object plane area according to a specified projection depth and projection direction to obtain a projection space in the 3D space, wherein the projection space comprises a space area between the generated object plane area and the projected object plane area; and determining that data points included in the projection space in the 3D point cloud data are data points belonging to the received object type.

Description

technical field [0001] The present application relates to the field of data labeling, in particular to a method, device and storage medium for labeling objects in 3D point cloud data. Background technique [0002] In the related art, when labeling an object in 3D point cloud data, the multiple points constituting the object are usually labeled one by one, that is, single-point labeling is performed. When annotating, the annotator annotates the corresponding color or annotates the corresponding type to the single point. Contents of the invention [0003] The present application provides a method, device, and storage medium for marking objects in 3D point cloud data to solve the problem in the prior art that objects in 3D point cloud data cannot be marked efficiently. [0004] On the one hand, some embodiments of the present application provide a method for labeling objects in 3D point cloud data, including: [0005] The labeling device displays a frame of 3D point cloud d...
