Abstract

A computing system, including at least one imaging sensor configured to collect imaging data of a physical environment. The computing system may further include a processor configured to generate, based on the imaging data, a first anchor graph including a first plurality of anchors connected by a first plurality of edges. Each anchor of the first plurality of anchors may indicate a respective estimated position in the physical environment. The processor may be further configured to detect a change in the estimated position of at least one anchor of the first plurality of anchors relative to the at least one imaging sensor. Based on the change in the estimated position, the processor may reposition the first anchor graph relative to the at least one imaging sensor. Estimated lengths of the first plurality of edges and estimated angles between the first plurality of edges may remain fixed.
