Nadgradnja osvetlitvenega modula sistema s strojnim vidom

Ferjan, Miha (avtor), Tomaževič, Dejan (mentor)

Namen diplomskega dela je nadgradnja osvetlitvenega modula obstoječega sistema s strojnim vidom. Posodobljen osvetlitveni modul, ki ga sestavljata svetilo in krmilnik svetila, mora biti mehansko ter električno združljiv z obstoječim sistemom. Zaradi opuščanja proizvodnje trenutno uporabljenih svetlečih diod, ki generirajo svetlobo na svetilu, je treba svetleče diode zamenjati z novimi tipi svetlečih diod, ki so množično v uporabi. Z uvajanjem novih tipov svetlečih diod se kaže potreba po uvedbi sekundarnih in terciarnih optičnih elementov za vodenje in razprševanje svetlobe svetlečih diod. Posodobljen krmilnik svetil je nadgradnja trenutnega krmilnika z možnostjo uporabe z vsemi tipi zgoraj naštetimi svetlečimi diodami. Za namen analize svetil smo izdelali merilni sistem z uporabo barvne kamere, s katerim smo vrednotili prototipna svetila. Merilni sistem se z manjšimi posodobitvami lahko uporablja v proizvodnem procesu za zagotavljanje kakovosti izdelanih svetil pred integracijo v napravo. Svetilo smo preizkusili na obstoječem sistemu s strojnim vidom in rezultate primerjali s tistimi, pridobljenimi z merilnim sistemom. Na podlagi izvedenih meritev predlagamo in izdelamo osvetlitveni modul, ki bo nadomestil obstoječi osvetlitveni modul.

Izvleček

The aim of this thesis is an upgrade of the illumination module of the existing computer vision system. The upgraded illumination module, which consists of an illuminant and an illumination controller, must be mechanically and electrically compatible with the existing system. Because currently used LEDs are going out of production, LEDs should be replaced by new, more widely used types. With new types of LEDs, there is a need for implementation of secondary and tertiary optical elements in order to guide and diffuse the LED’s light. The upgrade of the illumination controller should enable the use of all the above-mentioned LEDs. For the purpose of illuminant analysis, we built a measuring system with a color camera to evaluate the prototype illuminants. With minor updates, the existing measuring system can be also used for quality control of the manufactured illuminants before integrating them into the computer vision system. Moreover, an illuminant was tested on the computer vision system and its results were compared with the results obtained by the measuring system. Based on the performed measurements, we propose to build a new illumination module which will replace the current one.
