Image analyzer for stereoscopic camera rig alignment

Abstract

The paper presents a versatile solution facilitating calibration of stereoscopic camera rigs for 3D cinematography and machine vision. Manual calibration of the rig and the camera can easily take several hours. The proposed device eases this process by providing the camera operator with several predefined analyses of the images from the cameras. The Image Analyzer is a compact stand-alone device designed for portable 19″ racks. Almost all video processing is performed on a modern Xilinx FPGA. It is supported by an ARM computer which provides control and video streaming over the Ethernet. The article presents its hardware, firmware and software architectures. The main focus is put on the image processing system implemented in the FPGA.
