A PERFORMANCE COMPARISON OF FEATURE DETECTORS FOR PLANETARY ROVER MAPPING AND LOCALIZATION [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Feature detection and matching are key techniques in computer vision and robotics, and have been successfully implemented in many fields. So far there is no performance comparison of feature detectors and matching methods for planetary mapping and rover ...

Dynamic Simulation Tool Development for Planetary Rovers

open access: yesInternational Journal of Advanced Robotic Systems, 2008
A dynamic computer simulator was developed to study planetary rover mobility. The simulator was validated for step-obstacle negotiation by comparing simulation results with a quasi-static analysis of a rocker-bogie suspension.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

An Efficient Dense Stereo Matching Method for Planetary Rover

open access: yesIEEE Access, 2019
Stereo matching is one of the most important and challenging subjects in the field of planetary rover with a stereo vision system. The generated disparity map can make rover to avoid the obstacle and explore the planetary surface automatically.

TTA-GEP: Terrain Traversability Analysis with Geometry and Environmental Perception for the Path Planning of Planetary Rovers

open access: yesInternational Journal of Aerospace Engineering, 2023
Terrain traversability analysis (TTA), the key to the navigation of planetary rovers, is significant to the safety of the rover. Therefore, owing to its complexity, the Martian terrain is worth analysing comprehensively based on the terrain variability ...

VISION BASED OBSTACLE DETECTION USING ROVER STEREO IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Vision based obstacle detection using stereo images is an essential way for hazard avoidance and path planning in planetary rover missions. However, due to light condition changes and topographic relief, only partial or sparse three-dimensional points ...

Vision-Based Decision Support for Rover Path Planning in the Chang’e-4 Mission

open access: yesRemote Sensing, 2020
In planetary rover missions, rover path planning is critical to ensure the safety and efficiency of the rover traverse and in situ explorations. In the Chang’e-4 (CE-4) mission, we have proposed and developed vision-based decision support methods ...

Dust, Sand, and Winds Within an Active Martian Storm in Jezero Crater

open access: yesGeophysical Research Letters, 2022
Rovers and landers on Mars have experienced local, regional, and planetary‐scale dust storms. However, in situ documentation of active lifting within storms has remained elusive.

Terrain mapping for a walking planetary rover [PDF]

open access: yesIEEE Transactions on Robotics and Automation, 1994
Presents a terrain mapping system for walking robots that constructs quantitative models of surface geometry, The accuracy of the constructed maps enables safe, power-efficient locomotion over the natural, rugged terrain found on planetary surfaces. The mapping system acquires range images with a laser rangefinder, preprocesses and stores the images ...
