ABSTRACT:
A method is provided for converting joystick deflection into a speed of relative motion between a image system and a workpiece stage in a computer vision system. The conversion of joystick deflection into speed may be described in terms of a speed/deflection profile that corresponds a present lens characteristics of the system. In one embodiment, the speed/deflection response of the system depends relatively strongly on the present lens characteristic at relatively lower deflections and depends on relatively weakly on the present lens characteristic as the deflection approaches a maximum deflection. The system is advantageous in that, for any lens used, it maintains consistent ergonomic and visual feel at small joystick deflections which typically occur during ostensible precision maneuvers, but is also able to provide fast long-range traverses for large joystick deflections.
