Abstract
A method may include: receiving a first image captured by a camera at a first time instance, wherein the first image includes at least a portion of an observed vehicle; determining a first ray angle based on a coordinate system of an ego-vehicle and a coordinate system of the observed vehicle corresponding to the first image; receiving a second image captured by the camera at a second time instance, wherein the second image includes at least a portion of the observed vehicle oriented at a different viewpoint; determining a second ray angle based on a coordinate system of the ego-vehicle and the coordinate system of the observed vehicle corresponding to the second image; determining a local angle difference based on the first ray angle and the second ray angle; and training a deep neural network using the local angle difference, the first image, and the second image.
