Abstract :
About parallel processing of RS image in Grid. According to task decomposition pattern, there are two schemes: single image-multilateral process and single image-single process. On the base of the contrast and analysis of the two schemes, we use the single image - multilateral process scheme, focus on the trait of batch RS image processing, solve the problem of transmission of massive RS pictures with GridFTP module in MPICH-G2, and use OpenCV from Intel´s open source library to write complicated picture processing code. To prove the processing module for batch RS images, experiment of detection is made on edge of circular structure base on the first image transmitted from Chang´e-1 and deal with the image in this pattern.
