Automatic Feature Registration and Dem Generationfor Martian Surface Mapping
نویسندگان
چکیده
In this paper, we introduce the results of automatic registration, bundle adjustment, and DEM generation from panoramic close-range images taken on the 1997 Mars Pathfinder mission. Image registration is based on Förstner interest points, cross-correlation coefficient-based matching, parallax verification, and graph consistency verification. A free-network approach is used for bundle adjustment. The final product is a seamless DEM of the landing site created by a five-step process: automatic registration of intrastereo images, coarse DEM generation, automatic registration of inter-stereo images, bundle adjustment of the entire panorama, and seamless DEM generation.

DEM-based analysis of morphometric features in humid and hyper-arid environments using artificial neural network
Abstract This paper presents a robust approach using artificial neural networks in the form of a Self Organizing Map (SOM) as a semi-automatic method for analysis and identification of morphometric features in two completely different environments, the Man and Biosphere Reserve “Eastern Carpathians” (Central Europe) in a complex mountainous humid area and Yardangs in Lut Desert, Iran, a hyper...
متن کاملRobust Phase Correlation Based Feature Matchinig for Image Co-registration and Dem Generation
This paper presents a robust phase correlation based sub-pixel feature matching technique and its application in motion flow estimation, pixel-to-pixel image-co-registration and DEM generation. We propose to use a phase fringe filter and a highly robust technique in the direct Fourier-based phase correlation algorithm for translational shift estimation in sub-pixel accuracy. Noting the problem ...
متن کاملBlunder Elimination Techniques in Adaptive Automatic Terrain Extraction
This paper introduced a new automatic terrain extraction (ATE) module inside ERDAS’s photogrammetric software LPS. This method uses a global DEM to initialize a surface model and iteratively refines it with image registration on different pyramid levels. Search range used in image registration is adaptively controlled by elevation range of matched feature points. However, mismatches and elevati...

This paper presents a method for co-registration of Chang’E-1 lunar orbiter stereo images and laser altimeter (LAM) data for 3D mapping of lunar surface. First, a digital elevation model (DEM) is automatically generated from the three-line CCD stereo images based on rigorous pushbroom sensor model and multi-level image matching. The DEM is then registered to LAM data through surface matching wi...
متن کاملAutomatic Mars Landing Site Mapping Using Surface-based Images
This paper presents techniques for automatic mapping of Mars landing sites using surface-based images, i.e., those taken by Mars landers and/or rovers. An innovative method for automatic tie point selection is presented that includes five steps: interest point extraction, interest point matching, parallax verification, graph consistency verification and final tie point selection with gridding. ...
