A Time-Of-Flight Depth Sensor - System Description, Issues and Solutions

Abstract: This paper describes a CMOS-based time-of-flight depth sensor and presents some experimental data while addressing various issues arising from its use. Our system is a single-chip solution based on a special CMOS pixel structure that can extract phase information from the received light pulses. The sensor chip integrates a 64x64 pixel array with a high-speed clock generator and ADC. A unique advantage of the chip is that it can be manufactured with an ordinary CMOS process. Compared with other types of depth s… Show more

“…The reflected light is then compared to the original one, calculating the phase shift, by means of measuring the intensity of the incoming light since the phase shift is proportional to the time of flight of the light reflected by a distant object. A detailed description of the time-of-flight principle can be found in Gokturk et al (2004).…”

“…Active depth cameras have been receiving a lot of attention since the recent introduction of Kinect from Microsoft. The sensor captures the distance information very reliably with a resolution of 640×480 and is available at a relatively low cost compared to that of other depth cameras [20], [21]. However the cost is still more than ten times that of general CMOS cameras, which is a critical factor in mass production.…”

“…The chosen PMD CamCube 3.0 utilizes Radio Frequency (RF) modulated light sources with phase detectors. The modulated outgoing beam is sent out with a RF carrier, and the phase shift of that carrier is measured on the receiver side to compute the distance (Gokturk, et al, 2010). Compared with traditional LIDAR scanners and stereo vision, TOF camera possesses ideal features of being deployed in real-time applications: captures a complete scene with one shot and speeds up to 40 frames per second (fps).…”
