Abstract
A method and apparatus for locating objects by means of machine vision alignment using cooperative targets. Novel cooperative targets are used that have substantial performance advantages. Alignment methods having non-translation alignment capabilities are used, such as geometric pattern matching, cooperating with suitable targets to perform alignment in non-translation degrees of freedom, such as orientation and size.
