Paper Abstract

This paper describes the principle of the spatial encoding- based rangefinder. Its parameters to be calibrate are found out. Mathematical expressions are deduced of its measurement errors caused by calibration errors. Analysis shows that it is difficult to calibrate the parameters separately, especially some parameters are unable to calibrate. So we present a new calibrating method based on table. In the normal operation of the rangefinder, it directly obtains the ranges the pixels of the image of the object from the table after giving its codes. Our calibrating method has the advantages of simple and high accuracy.
