Aplicação de técnicas de engenharia de software no desenvolvimento de um sistema para análise de matrizes químicas por meio de imagem digital

Abstract

The use of computer tools in business, science and engineering made it become essential nowadays and enabled the creation of new technologies in the field of administration, medicine, telecommunication and others. Each day new systems are implanted in order to improve more and more the users’ dealing with it. Nevertheless, most of them have a generalized operation system that not always meets the user’s specific needs. This way to have a computerized system and that can meet each user’s peculiarities, it is necessary to manufacture it based on software engineering guideline. Besides the application of software engineering technique, it was necessary to acquire specific knowledge about image processing and analytic chemistry. The conducted research outcome, contemplates a digital image system (SISAID) which entailed acquisition technique and image processing of chemical matrices, the acquisition of image was gotten by the use of webcam in the titulação process (chemical process) that interacts with the system and the system makes the image processing, based on color model RGB (Red, Green, Blue) the system also carries out the calculation of medium values of RGB and the NORMA of the vector RGB, those which make the image analysis possible through the titulação bend created by the system. Plus one can verify the obtained results through SISAD with results gotten, digital image analysis system used in the chemical laboratory of Instituto de Ciências Exatas e Tecnologia and it was noticed that the SISAID can bring about more efficiency regarding time. As the user got through the operation of the system in a shorter time, and was able to get satisfactory results concerning the titulação bend.
