A Kaleidoscopic Geometric Vision Platform (KGVP) that transforms three-dimensional (3D) machine vision through an optical system that creates multiple virtual laser projectors from a single moving component. A spindle mirror mechanism (SMM) rotates a reflective surface to sweep collimated laser beams in circular patterns. These beams strike a series of kaleidoscopic mirror facets (KMFs) arranged concentrically around the SMM in a concave configuration. Each KMF redirects the rotating beam, creating a virtual projector with a distinct origin point and sweep direction. As the SMM completes one rotation, it generates N distinct laser trajectories (where N equals the number of KMFs), each sweeping from a different virtual origin point. Event-based cameras / sensors positioned strategically around the KMFs detect laser light reflected from object surfaces with microsecond precision. The KGVP triangulates 3D surface coordinates by determining correspondence between detected light and specific virtual projectors based on precise timing information.

Event-based cameras / sensors positioned strategically around the KMFs detect laser light reflected from object surfaces with microsecond precision. The KGVP triangulates 3D surface coordinates by determining correspondence between detected light and specific virtual projectors based on precise timing information. This approach eliminates the computational complexity typically required for multi-view feature matching, as the KGVP can unambiguously identify which virtual projector created each detected event. With calibration, the KGVP can establish the exact 3D positions of all virtual projector origins and their beam trajectories and build look-up tables that optimize triangulation accuracy. The KGVP enables real-time 3D surface reconstruction with high precision while using far fewer mechanical components than conventional machine vision systems.
