Abstract
A computer-implemented method implements a resilient interdependent spatial alignment (RISA) process to improve and maintain spatial alignment between two associated coordinate systems by moving a follow coordinate system to align it to a lead coordinate system. In some use cases, the coordinate systems may be a physical space and a corresponding digital model of the space. A user device such as an augmented reality headset or robotic sensors may be moving in the physical space, and alignment to the model is continually maintained, updated and improved responsive to acquired spatial data to enable, for example, holographic display of the model in the headset very closely aligned to the physical space. Multiple volumes can each have corresponding digital “spaces” or RisaSites to manage anchor data with dynamic hand-off among them while accommodating differing scale and density.
