Abstract
A non-transitory computer readable medium embodies instructions that cause one or more processors to perform a method. The method includes selecting a 3D model corresponding to an object. The method further includes generating domain-adapted images of the 3D model, the domain-adapted images representing the 3D model at corresponding poses. The method further includes acquiring 2D projections of 3D points on a 3D bounding box defined around the 3D model at the corresponding poses. The method further includes training an algorithm model to learn correspondences between the generated images and the corresponding 2D projections. The method further includes storing, in a memory, parameters representing the algorithm model.
