Abstract:

According to the difference of the task separation pattern, parallel processing of batch RS image in grid environment can be divided into two programs, including single picture-multilateral process and single picture- single process. Based on the comparative analysis, the authors adopt single picture-single process, and use Grid-FTP under MPICH-G2 model to solve the problem of massive RS pictures transmission aiming at the characteristics of batch RS image processing task. Using the open source library of Open CV from Intel company to compile complicated picture handling code, and processing detection experiment of circular structure edge base on the first image of Chang'e-1 satellite, validate the pattern of the process of batch RS image in this paper.
