PCIAS represents Phase Correlation based Image Analysis System. It is a professional C++ software package to deliver advanced subpixel technology that has been developed during the last several years supported by the SEAS DTC (System Engineering for Autonomous Systems Defence Technology Centre). This paper provides and overview of the PCIAS. After a brief introduction to the principles and algorithms, the paper illustrates, with examples, the major applications based on high precision sub-pixel disparity estimation.
