High-precision multi source remote sensing data processing cooperative cluster system is based on grid computing, it is a complete solution which is suitable for rapid and batch processing of large-scale remote sensing images. This system is able to deal with various remote sensing images（include SAR data），and produces digital ortho products and digital elevation model (DEM) products rapidly，it is suitable for automatically fast data processing in emergency mode as well as high precision image processing in conventional mode.



一、System characteristics
1、Cross platform, extensible, open programmable, hardware and software integrated high performance computing environment
The client uses the Windows system to meet the diversity and flexibility of the interaction; the server uses the Linux system to ensure the stability and efficiency of the calculation.The nodes can be deployed in different hardware devices, such as the server, the blade machine, the graphics workstation, and so on. In addition to image processing, the system can also perform various powerful computing tasks by user's self-programming.
2、Multi source remote sensing data processing covering the full business, rich and varied product
Multi source---Support the sensor of visible light、LiDar、SAR and Hyperspectra. Support the remote sensing platform of space, aviation, low altitude unmanned aerial vehicle, vehicle and so on.
Full business---Support the entire business of satellite data，support array and linear aero data.

Multi level product----Ability of producing system geometric correction products, mosaic products, element information products as well as providing Image, terrain, model, element products.



二、Core functions and key technologues
1、Automatically homonym image point matching
Provide the function of rapid automatically homonym image point matching among various images.
2、Adjustment of large scale joint areas

Provide the regional net adjustment technology among large scale areas for high precision and rapid geometric correcting images.The ability of adjustment correction for multi-source include different satellites,payloads,observed data as well as irregular data of weak rendezvous、non stereoscopic、narrow field angle、weak connection、low overlap、unsystematic stripes and minimum base height ratio.



3、The rapid checking of adjustment for the result

Function of real time result checking after images adjustment correction.



4、Ortho fusion Images
Function of ortho and fusion correction for images.
5、Uniform Color mosaic images

Function of uniformed color and mosaicking images based on different resolutions and data format；Achieving automatically uniform color and mosaic large scale of images data by optimizing the algorithm which deals with the geometry and radiation information on edge of images.
