Abstract
Diplomski rad opisuje algoritme za dobivanje pogleda odozgo na vozilo koji se mogu koristiti u sustavu za autonomna vozila. U radu su opisane važne smjernice i koraci za uspješnu kalibraciju kamere. Algoritam za generiranje pogleda prostora oko automobila definira geometrijske operacije nad slikom kako bi se generirao cjeloviti i povezani pogled odozgo. Ove operacije uključuju ispravljanje izobličenja, transformaciju perspektive i spajanje slika. Algoritam se uspješno izvodi kada su kamere postavljene na vozilo s poznatim kalibracijskim parametrima i kada se nalaze na predviđenoj poziciji na vozilu. Važno je osigurati točnost kalibracijskih parametara i pravilno postavljanje kamera kako bi se postigao pouzdan i precizan pogled prostora oko vozila. Algoritam izrađen s YUV420SP formatom zapisa s brzinom obrade od 2.5 FPS za rezoluciju 1280 x 720 elemenata slike dobio je bolje subjektivne ocjene ispitanika od YUYV422I formata s brzinom obrade od 6.5 FPS za rezoluciju 640 x 360 elemenata slike. Daljnji napredak ovog algoritma može se postići nadogradnjom samog hardvera ploče i programske podrške kako bi se osigurala veća dostupna memorija i poboljšala ukupna izvedba sustava.
Abstract (english)
The thesis describes algorithms for obtaining a top-down view of a vehicle that can be used in an autonomous vehicle system. The work outlines important guidelines and steps for successful camera calibration. The algorithm for generating a surround view of the vehicle defines geometric operations on the image to create a comprehensive and connected top-down view. These operations include distortion correction, perspective transformation, and image stitching. The algorithm performs successfully when cameras are mounted on the vehicle with known calibration parameters and positioned as intended. Ensuring the accuracy of calibration parameters and proper camera placement is crucial to achieving a reliable and precise surround view. The algorithm implemented with the YUV420SP format, processing at 2.5 frames per second for a resolution of 1280 x 720, received better subjective ratings from the participants compared to the YUYV422I format, processing at 6.5 frames per second for a resolution of 640 x 360. Further advancement of this algorithm can be achieved by improving the hardware of the board and the software support to provide increased available memory and enhance the overall system performance.
