摘　　要：由于GPU(Graphic Processing Unit)在图像处理方面的良好性能,国内外已经有很多专家学者在应用GPU进行图像的并行处理.基于CUDA(Compute Unified Device Architecture)这种并行计算平台,利用GPU的强大计算功能对Hough变换中最耗时的部分进行计算.实验表明,这种方法对Hough变换的并行化有很好的加速效果.Due to the GPU （Graphic Processing Unit） in the field of image processing, good performance, there has been a lot of experts and scholars at home and abroad in the application of GPU for the parallel processing of the image. In this paper, based on CUDA （Compute Unified Device Architecture） this kind of parallel computing platform, using the powerful calculation function of GPU to the most time-consuming part of Hough transform to calculate. Parallel experiments show that this method of Hough transform has a good speedup.
