Abstract
An image pre-processing sub-system providing very high speed image data evaluation to supply condensed, real time boundary linkage data to a controlling computer of an operational system. The sub-system provides for an electronic video camera capable of the operations on an image of aiming, magnifying, and rotationally orienting. The camera direction, magnification and orientation control from the system computer results from visual image processed feedback from the image pre-processor with user tailored software providing the desired responses. Dual sub-systems, or a single sub-system at two sequentially different locations, provides triangulation information necessary for high speed distance measurements of objects from the camera. Visual data, detected by the camera, are processed to locate image boundaries, to filter noise, to enhance the boundary, to provide linkage boundary information, to provide texture data, and to provide shades of gray data to the computer in a condensed form. The sub-system adjustable magnification and rotation capability, of selected sub-areas of the full image, permit very high resolution image evaluation compatible with template matching techniques for object identification or inspection operations.
