Expedient Gap Definition Using 3D LADAR

Abstract

Abstract : This report presents a summary of the testing and analyses performed to determine the capabilities of a 3D LADAR (laser detection and ranging) system developed by Autonomous Solutions, Inc. (ASI). Under the direction of the U.S. Army Engineer Research and Development Center (ERDC), ASI has developed an algorithm to reduce the 3D point cloud acquired with the LADAR system into sets of 2D profiles that describe the terrain. This report provides data for (1) evaluating the ranging sensors that could potentially be used for measuring the geometry of a terrain gap, (2) reviewing results of the validation testing of the LADAR system, and (3) developing guidance for using LADAR systems to characterize terrain gaps. Validating the 3D LADAR system included the following tasks: (1) determining the effect of slope and depth of a gap on the measurements acquired with the LADAR system, (2) determining the effect of ambient light conditions on the measurements taken with the LADAR system, (3) determining the effect of different surface materials/textures on the measurements taken with the LADAR system, and (4) determining the effect of fog and dust on the measurements taken with the LADAR system. The project described in this report is part of the Battlespace Gap Definition and Defeat Army Technology Objective program.
