complete software and hardware implementation of our detection framework. In the process of con- structing this system, we have selected and modified computer vision techniques that are  appropriate  to the visual detection problem. Many of the techniques used by our framework (e.g. frame-differencing) have also appeared in similar forms in existing research, which is a demonstration of their usefulness. Our solution to the detection problem is innovative in the way in which it has uniquely combined these techniques into a general framework that can be directly applied to real-world situations. We have made modifications to these techniques where necessary, and we have also incorporated our own ideas where the existing literature was lacking (e.g. dynamic segmentation domains). Finally, we have customized the theory to the specihc industrial needs of robotics. This has demonstrated that our frame- work can provide precisely the type of information required to manage effectively a situation requiring visual detection. Results from experimentation with our visual servoing systems show the potential of our approach  under  general conditions. 机器视觉维修系统英文文献和中文翻译(2):http://www.751com.cn/fanyi/lunwen_80168.html
