Title:
THREE-DIMENSIONAL OBJECT DETECTION METHOD, COMPUTER DEVICE, STORAGE MEDIUM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/001804
Kind Code:
A1
Abstract:
The present invention relates to the technical field of visual inspection. Specifically provided are a three-dimensional object detection method, a computer device, a storage medium, and a vehicle, which aim to solve the problem of improving the accuracy of object detection. To this end, the method in the present invention comprises: performing object detection on a two-dimensional image by means of a three-dimensional object detection model, so as to acquire three-dimensional information of an object to be detected in the two-dimensional image. The three-dimensional object detection model is obtained by means of performing training in the following manner: performing object detection on a two-dimensional image sample by means of a three-dimensional object detection model to be trained, so as to acquire two-dimensional detection information and three-dimensional prediction information of an object sample in the two-dimensional image sample; projecting the three-dimensional prediction information, so as to obtain two-dimensional projection information; and according to the two-dimensional detection information and the two-dimensional projection information and by using a two-dimensional information consistency loss function, performing model training on the three-dimensional object detection model to be trained, so as to obtain a trained three-dimensional object detection model. In this way, both a close-range object and a long-range object can be detected.
