Curve Fitting Method Based on Adaptive Window for Center Extracting of Structured Light Stripe

LIU Tao,WANG Zongyi,YU Xiuhui,JIN Hongzhang(Automation College,Harbin Engineering University,Harbin 150001,CHN)  
In a structured light vision system,the accuracy of extracting the center position of the light stripe is very important.In this paper,basic extracting methods are discussed and a curve fitting method based on adaptive window for extracting the stripe center is proposed.While keeping the advantages of curve fitting,this method can also avoid the influence of size selection of the fitting window.Using this method the center of the stripe can be located at the sub-pixel level.In comparison with other methods,the experiment results show that,for this new method,the stability and precision are both improved in extracting the center of structured light stripe.
