The invention discloses a three-dimensional point cloud labeling method, a device, equipment and a storage medium, and belongs to the technical field of artificial intelligence. According to the quickthree-dimensional point cloud labeling method provided by the embodiment of the invention, the three-dimensional point clouds are displayed in the three-dimensional scene, and the three-dimensional point clouds are selected and labeled by utilizing the detected contour selection operation, so that a labeling person draws the contours of the objects in the three-dimensional scene, and the three-dimensional scene can automatically select the three-dimensional point clouds needing to be labeled. Thus, the tedious process that a labeler triggers selection operation on each point in the point cloud one by one is omitted, so that the labor cost and time expenditure for labeling the three-dimensional point cloud are saved, and the labeling efficiency of the three-dimensional point cloud is improved. Moreover, since the three-dimensional point clouds are displayed in the same three-dimensional scene, the spatial position relationship among different points in the three-dimensional point clouds can be intuitively reflected by utilizing the three-dimensional space provided by the three-dimensional scene, so that a labeler can label conveniently.
