Abstract
A positioning data correction apparatus with image analyzing, for producing a corrective positioning command used in a positioning device for positioning a tool along an axis with respect to a target on a work in response to a command, comprises: a receiver for receiving the command and a mode signal; a camera connected to the tool for producing an image signal with respect to the axis in response to light from the work; an image analyzer responsive to a control signal and to the image signal for detecting a position of the target by analyzing a pattern along the axis and for producing corrected positioning data by obtaining deviation of the position along the axis from a given point within an angle of field of the camera; and a controller responsive to the mode signal, the received command, and the corrected positioning, the controller operating: sending the received command to the positioning device; and for producing the control signal to case the image analyzer to product the corrected positioning data and producing the corrective positioning command in accordance with the corrected data in the presence of the external control signal.
