Abstract

Настоящото изобретение се отнася до система и метод за разпознаване и измерване на геометрични форми. По-специално, изобретението има за цел бързо и ефективно разпознаване на геометрични форми, такива като правоъгълници или паралелограми, присъстващи в снимка или друго цифрово придобиване на изображение и за възстановяване на неговите размери и позиция. Методът може да се използва за измерване на отвори, като например за врати или прозорци, присъстващи върху фасадата на сграда, които са част от рамкирани изображения и получени от смартфон или подобни устройства. Също така, методът има възможност да осигури средство за обработване на изображенията, придобити чрез добавяне на цифрови графични елементи, кохерентни на изображението, обработено по размери и перспектива.
