Image Sequence Based Lunar Landing Locating Algorithm

According to the requirements of the computer vision landing locating system on a Lunar lander,this paper proposed an algorithm to obtain the landing position of the Lunar lander using image sequence registration.This algorithm is based on SURF(Speeded Up Robust Features),and uses least squares to iteratively remove the mismatch point pair,finally gets the range of a image taken when just landed in a wide range Lunar image with latitude and longitude information to obtain the exact landing position,moreover,analyzes the error of the landing position.The experiment uses 2 kinds of simulated Lunar image sequence.The numerical results show that it achieves high registration accuracy and stability,and is qualified for engineering application.
