Abstract

U ovom radu razvijena je aplikacija za prepoznavanje jednostavnih električnih mreža korištenjem tehnika računalnog vida i dubokog učenja. Dijagram električne mreže aplikaciji se predaje u obliku slike, koja zatim u nekoliko koraka, postupcima prepoznavanja generira digitalni opis mreže u netlist formatu. Koraci uključuju preprocesiranje slike, raspoznavanje električnih komponenti, raspoznavanje linija te generiranje opisa. Aplikacija je razvijena korištenjem biblioteka OpenCV i TensorFlow. Prikazana je struktura i implementacijski detalji programskog rješenja. Na kraju su opisani dobiveni rezultati te su istaknuti nedostatci i mogućnosti proširenja.

Abstract (english)

In this master thesis an application for simple electrical circuit recognition based on computer vision and deep learning techniques is developed and described. The electrical circuit diagram is presented to the application as an image. As a final result, the application generates a digital description of the electrical circuit in the standard netlist format. The process of electrical circuit recognition includes following steps: image preprocessing, electrical component recognition, line detection and creating the netlist output. The application was built using OpenCV and TensorFlow libraries. The structure and implementation details of the solution are presented together with obtained results. Weaknesses and possible improvements that could be made are highlighted too.
