This paper introduces a way to process remote sense image (RS) based on GPU. Firstly, it introduces the common concept of GPU computing based on OpenCL, finds out the impact of GPU on RS image process algorithms; Secondly, it uses a real RS image as experiment data, finds out how to accommodate this impact when using GPU. Thirdly, according the experiment result, it gives the experiences of RS image process based on GPU. At the end, it summarizes the method of using GPU to process RS image.%介绍以OpenCL为基础，探讨以GPU对遥感影像进行处理的方法。首先介绍利用OpenCL进行GPU运算的一般性概念，对比GPU运算给遥感影像处理算法带来的影响；其次以实际的遥感影像为例，探讨在使用GPU处理遥感影像时，如何应对前一步所述的影响；接着根据实验结果给出在遥感影像算法中使用OpenCL利用GPU进行运算的总结性经验。最后，对比分别采用GPU和CPU的算法，总结出GPU算法在遥感影像处理方面的方法。
