Abstract

Tema rada rekonstrukcija je dvodimenzionalne i trodimenzionalne scene sažetim očitavanjem. U okviru rada osmišljen je i realiziran sustav za rekonstrukciju dvodimenzionalne scene metodom sažetog očitavanja. Navedeni sustav sastoji se od digitalne kamere i projektora. Opisana je osnovna ideja razvoja sustava za rekonstrukciju trodimenzionalne scene sažetim očitavanjem. Eksperimentalni rezultati rekonstrukcije dvodimenzionalne scene metodom sažetog očitavanja sadržani u radu su zadovoljavajući. Informacijski sadržaj rekonstruirane scene uspješno je obnovljen iz reduciranog skupa uzoraka signala te odgovara informacijskom sadržaju originalne scene. Rad potvrđuje činjenicu kako je metodom sažetog očitavanja moguće iz reduciranog skupa snimljenih uzoraka statistički pouzdano rekonstruirati polazni signal.

Abstract (english)

This thesis theme is reconstruction of two-dimensional and three-dimensional scenes using compressive sensing. In the thesis, system for reconstruction of two-dimensional scene using compressive sensing method has been designed and developed. The system is made of digital camera and a projector. Basic idea of three-dimensional scene reconstruction using compressive sensing has been described. Experimental results of two-dimensional scene reconstruction using compressive sensing method have been presented and are satisfying. Informational content of the scene is successfully reconstructed from reduced number of measurements and it is equal to the informational content of original scene. This thesis confirms the fact that compressive sensing method is able to reconstruct the original signal from reduced number of measurements with certain statistical reliability.
