摘要:
The invention relates to a laser sensor meant to non-contact determine the distances, position and movement of different objects, destined to robotic, medical/biomedical, virtual reality-type applications, to man-computer interface systems and to multimedia applications. According to the invention, the sensor consists of a system for generating at least a laser plane (3) making a constant angle with the horizontal plane (2), a video camera (9) which acquires two images, a first image (10) being acquired with the laser plane active, while the second image (11) - with the laser plane inactive, and an electronic system for image processing which extracts the projection (8) of the laser plane onto the objects in the close vicinity by means of an algorithm for comparing the two images (10 and 11).Invenţia se referă la un senzor laser, destinat determinării noncontact a distanţelor, poziţiei şi a mişcării diferitelor obiecte, destinat aplicaţiilor robotice, medicale/biomedicale, de tip realitate virtuală, sistemelor de interfaţare om-calculator şi aplicaţiilor multimedia. Senzorul conform invenţiei este alcătuit dintr-un sistem de generare cel puţin a unui plan (3) laser, ce face un unghi constant cu planul (2) orizontal, dintr-o cameră video (9), ce achiziţionează două imagini, prima imagine (10) fiind achiziţionată cu planul laser activ, iar cea de-a doua imagine (11) - cu planul laser inactiv, şi dintr-un sistem electronic de procesare a imaginilor, ce extrage proiecţia (8) planului laser pe obiectele din imediata vecinătate, printr-un algoritm de comparare a celor două imagini (10 şi 11).
