Ultrasonic sensors are well established in various industrial, medical and commercial applications. A specific subclass of these applications employs ultrasonic sensors to obtain information of objects within the vicinity of the sensor. Using a compact 3D-ultrasonic sensor as a basic building block, applications can be classified into three different groups, based on the reference system used. The first group employs a global reference system, in which position and orientation of the sensor are known, and whereas the objects are described herein. Possible applications include scene analysis where the sensor detects objects within the environment. The second group uses the reference system of the sensor where the sensor is not expected to move after initial calibration. Multiple fixed sensors can be used for identifying and localizing of possibly moving objects. The third application uses the sensor in combination with a movable robot controlled by sensor information. The sensor can be seen similar to the navigation system of a bat. Two example applications will be highlighted within this article showing the applicability of the system using a global reference system for scene analysis, and secondly employing two compact 3D sensors operating in a group, to identify size and orientation of primitive objects on a linear belt.
