The CCD sensors have the advantage for small size clear image and low prices, It is the image capture unit of computer-vision system which developed fast in the past years, especially in the 2-D image capture CCD sensors are better then another sensors, so in the industry it be used on products detection . There are two different sections on using CCD sensors to detect products,the first section is about the detection of what kind of objects amount of objects and position of objects, the second section is about looking for lines ¡Bcircles ¡Bareas of objects¡Bdiameter¡Bcircularity and the angles between two lines The research purpose is finding a high accuracy algorithmic with low complicacy and high accuracy conditions; the accuracy can reach the sub-pixel accuracy with low price facilities and high speed .
