Aiming at the problem that the fixed lens cannot achieve full-area shooting recognition and obtaining the target position within the target area. This paper proposes using a moving vision lens to perform shooting recognition at fixed points and sub-regions within the set search path to determine the target object’s visual coordinates and use PID calculation to drive the actuator to complete the target workpiece grabbing. The system has high positioning accuracy through experimental verification, and the correct identification and capture can reach 100%.
