Abstract

U ovom radu opisano je postavljanje virtualne scene strukturiranog svjetla u Blenderu koja se sastoji od projektora i dvije kamere te snimanog objekta. Opisane su veze između modela kamere i projektora u računalnom vidu i računalnoj grafici te specificirane formule potrebne za pretvorbu parametara. Poseban naglasak je na parametrima projektora zbog najveće razlike modela u računalnom vidu i računalnoj grafici. Provedena je i kalibracija sustava snimanjem simulirane kalibracijske ploče u zraku te uronjene u tank za vodu također modeliran na temelju stvarnog tanka sa staklenim stijenama odgovarajuće debljine. Predložen je način verifikacije algoritma pomoću invarijantnih varijabli scene, kojima je i potvrđena točnost simulacije postavljene scene.

Abstract (english)

This paper describes the setting of a virtual structured light scene in a blender consisting of a projector, two cameras and an observed object. The connections between the camera and the projector models in computer vision and computer graphics are described, and the formulas needed to convert the parameters are specified. Special emphasis is placed on the parameters of the projector due to the largest difference between the model in computer vision and computer graphics. The system was also calibrated by recording a simulated calibration plate in the air and immersed in a water tank also modeled on the basis of an actual tank with glass walls of appropriate thickness. A way of verifying the algorithm using invariant variables of the scene is proposed, which also confirmed the accuracy of the simulation of the set scene.
