Abstract
Image processing is necessary for three-dimensional information recovering of stereovision measurement system and it is always bottleneck for real-time applications. In order to accelerate system computational power, the design of SOPC system which can fulfills image processing tasks parallel is discussed. As a part of high-speed stereovision measurement system, the application specific SOPC is designed as an embedded PCI board card of hosts PC. This paper focuses on three aspects. Firstly, Principles of SOPC system designing and SOPC features selecting are analyzed with measuring requirements under consideration. Then the realization of SOPC system is described in detail. The embedded processor, special IPs (Intelligent Properties), several custom logic modules are included in a single FPGA. All units are seamlessly integrated into the overall system using the system builder interface. The parallel processing is illustrated by examples. In the end, simulation and debugging results of SOPC system are introduced. Elements that influence running time are analyzed and final results are given. Experiment and test results show that all the functions needed were realized with much higher efficiency and processing speed in our SOPC system than conventional software.
