In May 2008, the Autonomous Landing and Hazard Avoidance Technology (ALHAT) Project conducted a helicopter field test of a commercial flash lidar to assess its applicability to safe lunar landing. The helicopter flew several flights, which covered a variety of slant ranges and viewing angles, over man-made and natural lunar-like terrains. The collected data were analyzed to assess the performance...
From May 2 through May 7 of 2008, the Autonomous Landing and Hazard Avoidance Technology (ALHAT) Exploration Technology Development Program carried out a helicopter field test to assess the use of a flash LIDAR as a primary sensor during lunar landing. The field test data has been used to evaluate the performance of the LIDAR system and of algorithms for LIDAR Hazard Detection and Avoidance, Hazard...
Mobile robots, operating in unconstrained indoor and outdoor environments, would benefit in many ways from perception of the human awareness around them. Knowledge of people's head pose and gaze directions would enable the robot to deduce which people are aware of the its presence, and to predict future motions of the people for better path planning. To make such inferences, requires estimating head...
