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.
