Modularly expansible system for real time processing of a TV display, useful in particular for the acquisition of coordinates of known shape objects and method using said system in radiography.

摘要

A modularly expansible system is disclosed for real time processing of a TV image or display, the system being particularly useful for the acquisition of coordinates of known shape objects, or objects with any shape and spatial lay, incorporating a correlation means (CR) which comprises a plurality of cascade connected stages, among which a stage adapted to parallelize a preset number of TV raster lines, at least one column delay line stage, at least one pre-adder stage, and a totalizing adder stage. The inventive system may be readily expanded by interconnecting substantially alike modules, to thus find useful industrial scale application in a range of different fields, from the medical field to robotics. It may also be easily implemented at different levels of sophisticated design to practically meet any needs for real time in-line acquisition of known shape object coordinates.
