A viable real-time image acquisition system was introduced in this paper. The EP2C35F6728C8 was usesd in this system as the core processor. By using the VHDL language and giving a simulation effect in the circumstances of QUARTUS, the collection and cache of original image was completed in the system, which could ensure the continuity and integrity of the image data. With a simple external interface circuit, it is very convenient for people to use and transplant this system. What’s more, it is also highlighted for its lower power consumption and higher speed. Thus it can be widely used in video surveillance and other fields.

Image Acquisition System

This paper introduces a design of a high-speed image acquisition system based on Avalon bus which is supported with SOPC technology. Some peripherals embedded in Avalon bus were customized and utilized in this system, such as imaging unit, decoding unit and storage unit, and these improved the speed of the whole imaging system. The data is compressed to three-fourths of the original by the decoding unit. A custom DMA is designed for moving the image data to the two caches of the SDRAM. This approach discards the method that FIFO must be put up in the traditional data acquisition system. And therefore, it reduced the CPU’s task for data moving. At the same time, the image acquisition and the data transmission can complete a parallel job. Finally, the design is worked on the high-speed image acquisition system which is made up of 2K*2K CMOS image sensor. And it improved the image acquisition speed by three ways: data encoding, custom DMA controller and the parallel processing.

Considering the influence of the environment for the search-rescue robot to perform tasks, design scheme of the acquisition module for vision navigation system was determined. In the design, FPGA ping-pong operation method was used. The EP4CE15 main control chip module was completed with module method, and the software design of the system was completed, including Quartus II image acquisition project navigator and Nios II system configuration. Finally, the simulation of data transfer was carried on. Simulation results show that the embedded real-time image acquisition is stable.
