Optical Surface Position Encode and Application Research

Abstract

A surface position location means based on encode recognition is presented; the design of a new kind of absolute position optical mouse using this technology is completed. The position encode algorithm and the code recognition method based on image acquisition and image process are presented also. The structure of pen-type sensor system and light path design of it are discussed. The coordinate conversation algorithm and the detected technology of pen down and pen up are provided. The advantages of the new kind of mouse are that it can write and draw more easily than traditional mouse.
