Abstract

Dubinske kamere postaju sve dostupnije i korištenije. Problem dubinskih kamera je generiranje velike količine podataka. U ovom radu predstavljena je implementacija rješenja problema korištenjem trenutno dostupnog standarda za kompresiju H.264. Dubinska informacija se kodira kako bi se prilagodila video kompresiji te se potom s RGB video slikom kompresira H.264 standardom. Time se postiže značajna ušteda memorijskog prostora i omogućava jednostavniji prijenos trodimenzionalne informacije postojećom mrežnom infrastrukturom. Provedeno je iskustveno ispitivanje na malom broju korisnika. Rezultati iskustvenog ispitivanja su pokazali da nema značajnijeg gubitka u kvaliteti video zapisa umjerenim korištenjem kvantizacijskog parametra.

Abstract (english)

Depth cameras have become commonly available and used. The problem depth camera has is generation of very large amounts of data. This thesis introduces the implementation of the solution for the problem by using already available compression standard H.264. Depth information is first coded so it would be better prepared for the video compression and then it is, together with the RGB video data encoded by the H.264 standard. By doing so, required memory space is significantly reduced and easier network transfer of the three-dimensional information over the current infrastructure is accomplished. The testing of user experience is conducted on a small number of people. Results of the testing showed that there is no significant quality loss when using moderately high value of quantization parameter.
