Dynamic high accuracy 6-D measurement system with a vision agnostic non-blocking smart target

A novel smart target has been designed for vision agnostic systems to acquire six-dimensional (6-D)information of a moving object (x, y, z, pitch, yaw, and roll) with high accuracy. The smart target is motorized to constantly rotate toward the measurement instrument for non-blocking dynamic measurement. This invention offers unique advantages in supporting the vision agnostic systems to capture precise 6-Dinformation of an object that requires precision localization in a variety of applications, including registering multiple machines/tools/objects, adaptively locating objects for unplanned adaptive control, precisely tracking the pose of an object used by robot operations, and applications in machine and robot visions. The measured 6-D information can also be used as the feedback control for motion, relative position/orientation monitoring of two items, and data registration for in-process inspection.
