The research work in this dissertation aim to apply the advanced technique in practice, that ramifies three parts: at first, the basic study of the computer vision, especially the stereo vision, include their technical mechanisms, methods and algorithms resolves the same technical problems of endoscopy and ferrograhpy based on stereo vision. Secondly, the endoscopy of engine fault inspection based on stereovision is researched and the system faced to this application is developed, thus the problems of stereovision applied to macroscopical images such as endoscopic images are resolved in method and computation. In addition, inside scenes are reconstructed and typical damages of engine inside are analyzed. Thirdly, the investigations of system formation, methods applied and algorithms study of debris analysis based on stereovision is carried out. Thus the problems of stereovision applied in debris analysis are resolved mainly. Furthermore, the integrated method combine with 3D symbolic parameters is studied and discussed for the recognition of debris configuration in pilot.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
