Abstract
The biggest challenges in multimedia technologies are connecting with createing fully interactive virtual reality (VR) systems. This requires generating numerically or even better gathering real data about static or dynamic 3D objects and scenes and delivering them to virtual reality environment. Application of the structure light measurement system based on digital light projection supported by special data coding and processing technology allow to record 3D data with significantly higher accuracy of reconstructed shape and simplified data manipulation process. In the paper the general concept of virtual reality system supported by data gathered by means of structure light projection is presented. The methodology of conversion of cloud of measurement points (x,y,z,R,G,B) into virtual reality environment is described. The methodology of real time visualization of variable in time 3D object based on its coding by means of specially formed contours and their B-spline approximation is presented. The applicability of the methodology has been shown at the case of real object monitoring. The total processing path was successfully tested.
