Abstract
In one embodiment, a system of an ADV perceives an object in a perspective view of the ADV using an image capturing device mounted on the ADV. The system generates a 2D bounding box for the object based on an image of the object captured by the image capturing device. The system determines an orientation and a 3D size of the object based on the image. The system projects onto the image a 3D representation of the object based on the orientation and the 3D size of the object. The system determines a distance from the ADV to the object based on the 3D representation of the object and the generated 2D bounding box. The system generates a trajectory in view of the determined distance from the ADV to the object to control the ADV to navigate the ADV around the object.
