Abstract :
ALOS PRISM is designed to gather 2.5 m resolution triplet images to obtain accurate terrain data. In order to estimate height measurement accuracy for ALOS PRISM triplet images, this paper describes three kinds of accuracy: relative geometrical accuracy, height calculation accuracy from a view point of BH ratio, and accuracy of triplet matching. The experimental results show high BH ratio and triplet images of PRISM contribute to accurate measurement
