摘要

为解决光电经纬仪上高速率、高分辨率实时图像传输及处理瓶颈问题。本文提出了基于光纤传输的实时图像处理平台体系架构思想,设计了以 FPGA+多核 DSP结构的图像处理单元,实现高速实时图像经光纤传输至处理单元。在此基础上,开发了自定义的光纤图像传输协议。利用该协议,使得图像处理系统与各个分系统之间的光纤互联,以及高速实时图像光纤传输至显示子系统,处理子系统和记录子系统。本文阐述了系统总体结构思想,系统硬件原理设计和软件设计,并对其中的图像光纤传输协议设计,多核 DSP处理单元设计等进行详细介绍。搭建了实验测试平台,通过实验平台对系统进行测试和分析。实验结果表明,实时图像在光纤上进行 3.125 Gb/s、在 FPGA与多核 DSP之间进行 3.125 Gb/s速率上传输,系统稳定、可靠、误码率低,且具有处理能力强、抗电磁干扰性能强等优点,并已应用到实际工程项目中。

Abstract

To solve the bottleneck problem of high-speed, high-resolution real-time image transmission and processing on photoelectric theodolite, a framework of real-time image transmission based on optical fiber and FPGA + multi-core DSP processing unit is proposed, which means this design realized high-speed image transmit to multi-core DSP processing unit in real time. On this basis of that, a custom protocol of image transmission on optical fiber has been developed by using the protocol to interconnect image processing unit between various subsystems, such as displaying subsystem and recording subsystem. A collectivity design of system, hardware design and software design of system are described, especially designs of image transmission protocol and multi-core DSP processing unit, which are introduced in detail to build an experimental platform, test and analyze the system. Extensive experiments on the whole system validate that, real-time image transmission to subsystems gets rate at 2.5 Gb/s by optical fiber channel, and transmission gets rate at 3.125 Gb/s between the multi-core DSP and FPGA on multi-core DSP image processing unit. The system is stable, reliable and low error rate. It has advantages such as strong processing capacity, strong performance of anti-electromagnetism interference. This system has been applied in engineering projects.
