Abstract
A vision correction method for establishing the position of a tool center point (TCP) for a robot manipulator includes the steps of: defining a preset position of the TCP; defining a preset coordinate system Twith the preset position of the TCP as its origin; capturing a two-dimensional picture of the preset coordinate system Tto establish a visual coordinate system T; calculating a scaling ratio λ of the vision coordinate system Trelative to the preset coordinate system T; rotating the TCP relative to axes of the preset coordinate system T; capturing pictures of the TCP prior to and after rotation; calculating the deviation ΔP between the preset position and actual position of the TCP; correcting the preset position and corresponding coordinate system Tusing ΔP, and repeating the rotation through correction steps until ΔP is less than or equal to a maximum allowable deviation of the robot manipulator.
