This technology is a vision tracking system and method using a distance sensor that separates a mobile first body from a second body equipped with a vision sensor. It compensates for the movement of the first body using feedforward control based on distance sensors and combines it with feedback signals from the vision sensor to maintain target tracking performance.
Existing systems faced issues where vibrations or sudden directional changes during mobile robot operation caused targets to move out of the field of view of vision sensors fixed to the same body, or resulted in motion blur, leading to reduced recognition accuracy.
This technology proposes a feedforward control system that detects the movement and rotation of the first body using distance sensors to drive the second body in the opposite direction, while integrating feedback signals from the vision sensor itself. This allows for real-time correction of the second body's position and orientation, enabling stable target tracking. Applicable to patrol robots, mobile filming equipment, and logistics robots, it enhances the practicality of robot vision systems by maintaining target tracking even during driving vibrations and sharp turns.
