Mineral detection based on hyperspectral remote sensing imagery on Mars: From detection methods to fine mapping
Zhang, Liangpei; Ke, Tian; Zhong, Yanfei +2 more
Hyperspectral remote sensing is a commonly used technical means for mineral detection on the Martian surface, which has important implications for the study of Martian geological evolution and the study for potential biological signatures. The increasing volume of Martian remote sensing data and complex issues such as the intimate mixture of Marti…
Atmosphere-aware photoclinometry for pixel-wise 3D topographic mapping of Mars
Liu, Wai Chung; Wu, Bo
High-resolution topographic mapping is essential for scientific investigations and operational exploration of planets, such as Mars. Photoclinometry, which uses light scattered from a surface to reconstruct 3D topography, can retrieve subtle topographic details from monocular images. However, its performance is affected by the atmosphere of Mars, …
A systematic review and meta-analysis of Digital elevation model (DEM) fusion: pre-processing, methods and applications
Okolie, Chukwuma J.; Smit, Julian L.
The remote sensing community has identified data fusion as one of the key challenging topics of the 21st century. The subject of image fusion in two-dimensional (2D) space has been covered in several published reviews. However, the special case of 2.5D/3D Digital Elevation Model (DEM) fusion has not been addressed till date. DEM fusion is a key ap…
Bundle adjustment of satellite images based on an equivalent geometric sensor model with digital elevation model
Cao, Hui; Tao, Pengjie; Li, Haihong +1 more
High-precision georeferencing of satellite stereo images becomes a key issue in multi-source data integration, geometric processing, and analysis for many remote sensing applications. Using existing geographic data, including readily available public data, as geometric reference for georeferencing satellite imagery is an effective and feasible way…
Fusion of photogrammetric and photoclinometric information for high-resolution DEMs from Mars in-orbit imagery
Luo, Bin; Douté, Sylvain; Jiang, Cheng +1 more
High-resolution Digital Elevation Models (DEMs) of the Martian surface are instrumental for studying the red planet. The Mars Orbiter Laser Altimeter (MOLA) instrument onboard the Mars Global Surveyor provided global DEM of high vertical resolution but with a limited spatial resolution that is not enough for characterizing small geological objects…
Automatic detection of Martian dark slope streaks by machine learning using HiRISE images
Di, Kaichang; Wang, Yexin; Xin, Xin +1 more
Dark slope streaks (DSSs) on the Martian surface are one of the active geologic features that can be observed on Mars nowadays. The detection of DSS is a prerequisite for studying its appearance, morphology, and distribution to reveal its underlying geological mechanisms. In addition, increasingly massive amounts of Mars high resolution data are n…
Detection and estimation of ZY-3 three-line array image distortions caused by attitude oscillation
Tong, Xiaohua; Li, Lingyun; Liu, Shijie +5 more
ZY-3 is China's first civilian high-resolution stereo surveying and mapping satellite, which is equipped with a three-line array panchromatic stereo camera. However, high-resolution satellite images (HRSIs) often suffer from satellite attitude oscillation, which can cause image distortions, and thus affect the geo-positioning accuracy. This paper …
Geometric integration of high-resolution satellite imagery and airborne LiDAR data for improved geopositioning accuracy in metropolitan areas
Wu, Bo; Hu, Han; Zhu, Qing +3 more
High-resolution satellite imagery (HRSI) and airborne light detection and ranging (LiDAR) data are widely used for deriving 3D spatial information. However, the 3D spatial information derived from them in the same area can be inconsistent. Considering HRSI and LiDAR datasets taken from metropolitan areas as a case study, this paper presents a nove…
Accuracy assessment of airborne photogrammetrically derived high-resolution digital elevation models in a high mountain environment
Müller, Johann; Gärtner-Roer, Isabelle; Thee, Patrick +1 more
High-resolution digital elevation models (DEMs) generated by airborne remote sensing are frequently used to analyze landform structures (monotemporal) and geomorphological processes (multitemporal) in remote areas or areas of extreme terrain. In order to assess and quantify such structures and processes it is necessary to know the absolute accurac…
A new shape from shading technique with application to Mars Express HRSC images
Barnes, D.; O'Hara, R.
We have developed a new optimisation based shape from shading algorithm which is able to make use of sophisticated camera and reflectance models and does not require a good initialising surface. Surface shape consistent with ground truth is obtained when the technique is applied to both synthetic rendered surfaces and real images captured by the M…
