SDI image acquisition module for 3D applications

摘要

The paper presents an FMC module for acquisition of 3D image through SDI interface, designed for Registration of Stereoscopic Image (ROS3D) project. As a component of an upgradable FPGA-based system for rapid calibration of 3D camera rigs, the module serves the purpose of acquiring an SDI stream from a set of two cameras and outputting it to either a dedicated SDI output or an HDMI output after processing in the FPGA. The upgradability was achieved with use of a combination of an FMC Carrier Card with the FMC module, which could be redesigned for higher data throughput and replaced in the future. There was no available solution meeting the requirements of the system at the time of the project. The necessary design requirements are discussed and a short specification is given.
