2 April news, data from the National Intellectual Property Administration shows that Beijing Wanjie Technology Co., Ltd. has applied for a patent titled “A Point Cloud Data Augmentation Method and System for 3D Object Detection Tasks.” The application publication number is CN121767691A, application number is CN202311408470.7, publication date is March 31, 2026, filing date is October 27, 2023, inventors are Miao Jun, Wei Mengting, Deng Yongqiang, Liang Hao, Li Juanjuan, Qi Honggang, patent agency is Beijing Dongfang Shengfan Intellectual Property Agency Co., Ltd., patent agent Fan Wu Jiang, classification numbers G06V10/764, G06V10/774, G06V10/82, G06N3/084, G06N5/04, G06V20/64, G06N3/0464, G06V10/766.

Patent abstract shows that the present invention discloses a point cloud data augmentation method and system for 3D object detection tasks, including the following steps: obtaining the original point cloud dataset; constructing a 3D object detection network model, and based on the training set, performing iterative computation to obtain a 3D object detection network model after gradient descent; performing inference based on the validation set to obtain inference results and calculating the inference accuracy; perceiving the category strength of the inference accuracy to obtain data evaluation results; selecting target objects to be augmented from the original point cloud dataset; using a hybrid augmentation strategy based on the target objects to obtain augmented point cloud data; using the augmented data as a new training set to train the 3D object detection network model, completing point cloud data augmentation for 3D object detection tasks. The enhanced model’s generalization ability at different granularities improves the overall prediction accuracy of the final model more effectively.
