Research And Implementation Of Measurement Camera Based On Hardware And Software Co-design

With the development of computer science and electronic technology,embedded measurement camera has been paid more and more attention,and has been widely used in military,medical,industrial,agricultural and commercial fields.In the embedded technology,Cyclone V SoC series chip are new product in recent years.This series of chips make the high-performance dual-core Cortex-A9 ARM hard core and programmable logic tightly integrated.Through this integration makes these chips have the advantages of dealing with complex algorithms on processor,but also retain the features of traditional FPGA.In this paper,through the study of DE1-SoC development board and hardware and software co-design method,the measurement camera is designed and implemented for bridge deflection measurement.Compared with traditional computer based measurement cameras and embedded system based measurement cameras,the measurement camera of this paper simplifies the system and makes the system design more flexible.Meanwhile it satisfies the current measurement camera's demand for functions and performance in image transmission and measurement.This design also makes the hardware and software parts process concurrently becoming possible.The main contents of the thesis are as follows:First of all,based on the analysis of the current design of embedded measurement camera,this paper compares the features of different architectures,and proposes to design the measurement camera based on hardware and software co-design on DE1-SoC.Through the study of DE1-SoC development board related knowledge and hardware and software co-design method,this paper analyses the system needs and gives the appropriate hardware and software architecture design.Secondly,this paper designs the function modules on the basis of the architecture design.The FPGA logic part of the design includes image acquisition module,image processing module and image transmission module.For bridge deflection measurement,the HPS part of the design includes image processing software and human-computer interaction design.And this paper designs a special image transmission driver for the measurement camera,realizes the transplant of the OpenCV and the Node.js,which provides an efficient scheme for system design and implementation.Finally,through the experiment this paper summarizes the measurement camera,and describes the direction of the next research briefly.
