| 摘 要： | 当代图像处理，特别是基于大量密集科学计算的数据处理，需要用高度的并行处理技术来解决计算效率问题。然而处理速度更多依赖于具体的算法和系统实现间的相互联系，这就对进行并行处理的工作人员的并行技术及相关经验提出了一定的要求。为完成并行处理并加大并行计算效益，采用了。DirectCompute方法。针对工程中的角点匹配计算时延问题，凭借有效的硬件资源，对其进行了并行处理，提高了程序执行效率，并缩短了计算延时。

| Abstract: | Contemporary image processing, especially data processing based on a large number of intensive scientific com- puting, needs a high degree parallel processing technology to improve the computational efficiency. However, processing speed is more dependent on interrelation between specific algorithms and system implementation, which puts forward the re- quirements on parallel technology and relevant experience ot＂ the workers who are doing parallel processing. To complete paral- lel processing and make the parallel effectiveness highest, DirectCompute method was used. Relyed on the effective hardware resources, parallel processing was adopted to solve the calculation delay problem of corner matching in projects. It improved the program execution efficiency and shortened the calculation delay. |
