CMOS Sensor Allows Robots to ID Objects in 3-D

DUISBURG, Germany, May 17, 2012 — A new CMOS sensor implemented in unmanned aerial vehicles (UAVs) gives the aircraft autonomy, improving collision detection as well as enabling 3-D modeling of disaster areas and surveillance targets.

Researchers at the Fraunhofer Institute for Microelectronic Circuits and Systems (IMS) have developed a CMOS distance sensor for UAVs that can efficiently measure 3-D distances. Each pixel in the sensor is given a gray value and a distance value, enabling the UAV to sense where it is in relation to objects around it and to avoid collisions.

According to Werner Brockherde, head of the IMS development department, the sensor has a much higher resolution than radar and can resolve objects of 20 x 15 cm at a range of 7.5 m.

The sensor will also give accurate readings despite the interference of other bright-light sources. The shutter on the camera opens only for a few nanoseconds and takes two measurements. The first is taken using only ambient light; the other uses a light pulse that reflects off of surrounding objects. The sensor analyzes the two inputs and determines the required output in real time.

The sensor has myriad uses, from 3-D modeling of a disaster area for relief workers, to modeling of streets and buildings for urban planners.

Cameras using the sensors have been manufactured by TriDiCam, a spinoff company of Fraunhofer IMS, as part of the AVIGLE project, winner of the Hightech.NRW competition, which is funded by Land of North Rhine-Westphalia and the EU.

The IMS researchers will present their developments at the Fraunhofer CMOS Imaging Workshop in Duisburg on June 12 and 13.
