基于CPU与GPU/CUDA的数字图像处理程序的性能比较

Performance Comparison of Digital Image Processing Based on CPU and GPU/CUDA

测绘系统通常有大量图像处理工作,而户外图像采集系统更需要极高的实时性。通过对GPU与CPU分别进行数字图像处理性能测试,结果表明GPU并行计算可以大幅提高图像处理性能:可优化图像预处理、后处理速度,使测绘系统更加实时高效。

Surveying and Mapping System usually has a lot of images to process and Out-door Image Collection System calls for high realtime performance. The result of digital image processing tests on GPU and CPU showed that the performance of digital image processing could be greatly improved by GPU-based parallel computing. GPUbased parallel computing can increase the speed of image pre-processing and image post-processing so that the Surveying and Mapping System becomes more efficient and has high real-time performance.
