Kurzfassung englisch:
The usage of ultrasonic sensors for localization and scene analysis is favorable due to the specific properties of ultra sound in air. Such systems are insensitive to dust and foggy atmosphere, the low propagation speed of acoustic waves allow accurate measurements, sensors are inexpensive and due to specular reflection they have inherent data reduction. This article summarizes recent work of our research group in the area of local positioning systems (OP Systems) and scene analysis. LP systems are used for locating static or mobile devices within an environment. An important aspect for such systems to achieve good accuracy is initial calibration. We will present our proposed method for calibration including some experimental data in this article. Scene analysis is focusing on analyzing and building a model of an a-priori unknown environment. Such models include object types like planes, edges and corners as well as their respective positions and orientations within the environment. For such a task an active compact 3D ultrasonic sensors which returns bearing information of reflection points is necessary. We will present three different sensors types for this.
