Measurement error analysis and accuracy enhancement of 2D vision system for robotic drilling
Built a model of relative errors between drill and workpiece in robotic drilling. Described the principle of relative error measurement with 2D vision system. Determined the camera TCP to eliminate Abbe errors in vision-based measurement. Established error models of vision-based measurement. Proposed a method to control perpendicularity and object distance in measurement.
