Abstract: According to the increasing problem of low processing efficiency and computational bottleneck in massive remote sensing data,for providing a more efficient approach of big data processing of remote sensing,using OpenCL pa-rallel processing technology can accelerate the processing of remote sensing image based on program of general purpose GPU.The analyses of test results on heterogeneous GPU platforms indicate that OpenCL technology can dramatically increase velocity of distortion calibration of image and can achieve 29.1 times best speedup.Comparing to parallel processing of CUDA suggests that using OpenCL technology on heterogeneous platform has a common superiority.

Key words: OpenCL,CUDA,Parallel processing,Heterogeneous platform commonality,Distortion calibration
