介绍了一种应用在空间项目中,可以对合作目标进行自动识别和测量的CMOS相机系统。相机系统以E2V公司生产的EV76C560AR为图像传感器;以V4系列FPGA和C67x系列DSP为图像处理核心。文中着重描述了相机系统中数据流的处理过程,包括图像压缩,多通道数据交换,数据通讯。使用FPGA实现图像数据流的H.264格式压缩;用FPGA控制RT端实现相机系统在1553B总线上的信息通讯;有限状态机实现了图像数据流在FPGA、DSP和SRAM间的交换。此相机测量系统已经在初样载荷上稳定工作。
A CMOS camera measurement system which recognizes and measures the cooperative target in some space project is presented. EV76C560AR made by E2V is used as image sensor in the camera measurement system. The V4 series FPGA and C67x series DSP are the core of the image processing. The processing procedure of data streams including image compressing
data exchange and message communication is described. The paper uses FPGA to realize H.264 video code standard
the control of the RT terminal of 1553B bus
and the image data exchange among FPGA
DSP and SRAM by finite-state machine. This camera measurement system has been used in the space measure project.
