RESUMO
This work is concerned to the developing of a new process to vectorize low-level engineering drawings applied to electrical circuits diagrams, without using thinning neither skeleton tracing, as is common in the traditional methods. After this vectorization, was developed a recognizer to the symbols which constitute the diagram as such their interconections. This project presents a methodology based in finding the feature points of the image ( corners, ends of tines and crosses ) which can be the origin of the vectors that represent the image. The results show that this method is a new tine tracing method, possessing all the functions of the traditional thinning process, and it has some significant superiorities: a) it has faster processing speed; b) it is independent from the tine width value; c) it is easy to extract cross points, comers and end tines; d) it has hight ability of resisting noise, such as spurs on tines and smalltine break; e) it treats the original image with no loss of information, while thinning loses it in the traditional method, it is more suitable for further detail processing, entity recognition and drawing interpretation. In this project we also do a research on drawing interpretation, we recognize tines which belong to the entities, interconection lines and also some entities of the drawing ...Note: The complete abstract is available with the full electronic digital thesis or dissertations
