Abstract
required in a growing number of applications like robotic guidance, security and automotive. Scannerless Time-Of-Flight (TOF) based active 3D vision systems are capable of collecting depth profiles of entire scenes in fraction of seconds but have the disadvantage of using high voltage and expensive electronic components. In this contribution we describe the design and test of an integrated smart pixel with 3D vision capability, which attempts to address this kind of problems. The pixel, fabricated in standard 0.6μm CMOS technology, is suitable to be used in scan-nerless ranging systems. By means of a pulsed laser source, distance estimation is obtained by integrating the back-reflected signal in successive time windows.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
