Images Of Several Practical Goal Of Positioning Methods And Applications

Target Locating is a valuable discussing problem in image processing and computer vision. It plays a very important part in target detection and image analysis, and is widely applied in some fields in the complicated background, such as industry and traffic. This paper primarily studies the some methods for target locating.Firstly, locating algorithm based on spatial relationship is discussed in this paper and has applied in automatic checking train images. Some problems are analyzed which exit in this method.Secondly, another locating algorithm based on shape analysis is discussed and has applied in automatic checking beer bottle quality system. In this algorithm, one edge extraction algorithm Shenjun is adopted to get the edges of the target, and chain code is used to describing the target, and Hough transform is also adopted to locate the target.Finally, the locating algorithm based on template matching is discussed and has also applied in automatic checking train images. In this method, some techniques are analyzed and adopted such as correlation algorithm, algorithm based on projection and algorithm based on invariant moments of histogram.
