People's Republic of China

Overview

A 3D bounding box reconstruction method includes obtaining maskscorresponding to an object to be detected in images, obtaining a track direction according to the masks, generating a target contour according to one of the masks,using a transformation matrix to transform the target contour into a transformed contour, obtaining a first bounding box according to the transformed contour and the track direction, using the transformation matrix to transform the first bounding box into a second bounding box that corresponds to the target contour, obtaining first reference points according to the target contour and the second bounding box, using the transformation matrix to transform the first reference points into second reference points, using the second reference points to obtain a third bounding box, using the transformation matrix to transform the third bounding box into a fourth bounding box,and using the second bounding box and the fourth bounding box to obtain a 3D bounding box.
