Echolocation - How drones can hear walls
Рет қаралды 2,593
4 жыл бұрынCan a drone hear the shape of a room? Or rephrased: Is it possible to precisely measure the shape of a room using sound waves? Previous studies have already mathematically proven that four microphones and a loudspeaker are sufficient to pinpoint the walls and also calculate their inclination. Professor Gregor Kemper from the Technical University of Munich and his colleague, Professor Mireille Boutin, who is working at Purdue University in Indiana, therefore took the idea a step further. In their theoretical approach, they placed a loudspeaker and four microphones on a drone.

Interessante Idee, aber wenn man einen Raum ausmessen wollen würde, könnte man doch einfach pro Arm der Drohne einen Laser-Entfernungsmesser befestigen und die Drohne sich um die eigene Achse drehen lassen. So könnte man die Größe des Raumes sehr genau errechnen, wobei ich leider nicht ganz einschätzen kann, wie exakt man so etwas mit Schall ausmessen könnte. Durch Auf-und-ab-fliegen könnte an auch die Schräge der Wände ausmessen. Ps: Ich würde mich übe eine Antwort freuen :)

can anyone who understands this better comment what advantage sound has over other technologies being used, particularly EM based sensors

You can use sound-based robotic platforms to estimate wall distances in complete darkness and also detect transparent surfaces typically found in office environment for room map generation.
