Object tracking based on dynamically built environment map data

摘要

A computer-implemented method of tracking a target object in an object recognition system includes acquiring a plurality of images with a camera. The method further includes simultaneously tracking the target object and dynamically building environment map data from the plurality of images. The tracking of the target object includes attempting to estimate a target pose of the target object with respect to the camera based on at least one of the plurality of images and based on target map data. Next, the method determines whether the tracking of the target object with respect to the camera is successful. If not, then the method includes inferring the target pose with respect to the camera based on the dynamically built environment map data. In one aspect the method includes fusing the inferred target pose with the actual target pose even if tracking is successful to improve robustness.

1. A computer-implemented method of tracking a target object in an object recognition system, the method comprising:
acquiring a plurality of images with a camera; simultaneously tracking the target object and dynamically building environment map data from the plurality of images, wherein tracking the target object includes attempting to estimate a target pose of the target object with respect to the camera based on at least one of the plurality of images and based on target map data; determining whether the tracking of the target object with respect to the camera is successful; and, if not, then inferring the target pose with respect to the camera based on the environment map data.
