Abstract
Systems and methods are described herein wherein a localizer is configured to detect a position of a first object and a vision device is configured to generate a depth map of surfaces near the first object. A virtual model corresponding to the first object is accessed, and a positional relationship between the localizer and the vision device in a common coordinate system is identified. An expected depth map of the vision device is then generated based on the detected position of the first object, the virtual model, and the positional relationship. A portion of the actual depth map that fails to match the expected depth map is identified, and a second object is recognize based on the identified portion.
