Abstract
A method and system by which a bounding box disposed around a segmented object in a camera (or other perception sensor) 2D image can be used to produce an estimate for both the location of the object—its position relative to the position of the camera that obtained the image (i.e., translation)—and the angle of rotation of the surface that the object is located on. The method and system may be used by an advanced driver assistance system (ADAS), an autonomous driving (AD) system, or the like. The input includes a simple camera (or other perception sensor) 2D image, with the ego vehicle generating 2D or 3D bounding boxes for objects detected at the scene. The output includes, for each object, its estimated distance from the ego vehicle camera/perception sensor and the angle of rotation of the surface underneath the object relative to the surface underneath the ego vehicle.
