Development of Knowledge-based Measurement with Monocular Vision

In this tutorial, knowledge-based visual measure methods with monocular vision system are investigated. The approaches of visual measure based on knowledge known in advance can be classified to four basic categories according to the types of knowledge, such as point position, line, size or shape knowledge, and motion knowledge. The principle for each category is shortly introduced. Furthermore, visual measure methods based on environment information are also discussed. Finally, conclusion and outlook for the development of knowledge-based visual measure are presented.
