Calibration of stereoscopic camera rigs using dedicated real-time SDI video processor

The paper presents a FPGA-based dedicated system for rapid calibration of 3D camera rigs. The developed device aims to help during camera set-up, by allowing the operator to easily compare the images from two cameras with use of several composition methods. The paper indicates the challenges related to development of high-throughput video processing systems in FPGA circuits. The processing methods were developed and verified using a platform with recent Kintex-7 FPGA device from Xilinx. The article covers the details of the implementation of the image analyser prototype. Moreover it identifies the crucial design considerations and addresses the problems that any FPGA designer can encounter during development of video processing systems.
