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.
