8On-Board Image Ortho-Rectification Using Collinearity
8.1INTRODUCTION
Given technological development, remotely sensed images can be acquired quickly and easily. However, the speed of image processing cannot catch up with the speed of obtaining remote sensing images because of the limitations of image processing technology. Conventionally, to process the acquired images (such as mosaic, fusion and ortho-rectification), they need to be sent back to the ground performance center. Moreover, many traditional image processing systems, such as ENVI and ERDAS IMAGINE, are serial instruction systems based on personal computers (PC). Thus, these image processing systems hardly meet the demand in response of time-critical ...
