METHOD AND APPARATUS FOR DETERMINING THREE-DIMENSIONAL INFORMATION OF TARGET OBJECT

The embodiments of the present disclosure provide a method and apparatus for determining three-dimensional information of a target object. The method includes: obtaining an image captured by a vehicle camera; and determining, based on a residual, optimized three-dimensional information of the target object in a target image, where the residual is determined based on two-dimensional information and projection information obtained by reprojecting three-dimensional information onto a two-dimensional plane, and the two-dimensional information and the three-dimensional information of the target object are determined in the image. The embodiments of the present disclosure do not rely on three-dimensional point cloud information, but mainly rely on two-dimensional information and three-dimensional information determined from two-dimensional images. Since the two-dimensional information has high measurement accuracy in rain and fog, night, and high speed environments, the method of the present disclosure has good robustness.
