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.

图像分析仪，用于立体相机台架对准

本文提出了一种通用的解决方案，该解决方案有助于对用于3D摄影和机器视觉的立体相机装置进行校准。手动校准钻机和摄像机可能需要几个小时。所提出的设备通过向摄像机操作员提供来自摄像机的图像的若干预定义分析来简化该过程。图像分析仪是为便携式19英寸机架设计的紧凑型独立设备。几乎所有视频处理都是在现代Xilinx FPGA上执行的。ARM计算机支持它，该计算机通过以太网提供控制和视频流。本文介绍了其硬件，固件和软件体系结构。主要重点放在FPGA中实现的图像处理系统上。
