Abstract

In the CCD of Fiber sensing measurement system, the orientation of light-spot pixel position which decides the accuracy of the entire system is very important. Based on the traditional center of gravity algorithm, a new algorithm which adopts weight nonlinearity and linear interpolation is proposed. And it is compared the precision of system using two algorithm under different noise level. The simulation result shows that the new algorithm can reach 0.05 pixel of orientation precision, it is much more precise and stable.
