A 3D Airborne Ultrasound Sensor for High-Precision Location Data Estimation and Conjunction

Abstract

Airborne ultrasound represents a robust tool for gathering 3D scene information especially in terms of robotics. We present an ultrasound sensor for high precision determination of reflection points in a specular environment, optimized for the suppression of deviations caused by air turbulence. By joining data of measurements from different positions an improved estimation of basic geometric objects, especially of curved objects is reached.
