Abstract
Based on the analysis on the bottleneck for improving CCD measurement resolving power in the high-accuracy image detection system, sub-pixel subdivision technology is presented. Through comparison the advantage and disadvantage of current subdivision algorithms, we propose a new 1D sub- pixel subdivision algorithm called Adaptive Weighing Fitting algorithm in the paper, which is suitable for such image as low contrast, low SNR and complex background. And we implement the real-time algorithm in the high-speed system platform based on TMS320C50. Then a fast 2D sub-pixel subdivision algorithm based on correlation feature and direction feature of image border is also discussed for improving the location accuracy of complex border. By many simulation experiments and practical detection in spot, the satisfied subdivision result are obtained.
