Live demonstration: The “DAVIS” Dynamic and Active-Pixel Vision Sensor

2014
Conference Papers

Abstract

This demonstration will show the features of the Dynamic and Active-Pixel Vision Sensor (DAVIS) reported at the VLSI Symposium and the International Imager Sensor Workshop in 2013. This sensor concurrently outputs conventional CMOS image sensor frames and sparse, low-latency dynamic vision sensor events from the same pixels, sharing the same photodiodes. The setup will allow visitors to explore the advantages of combining of fast and computationally-efficient neuromorphic event-driven vision with the existing body of methods for frame-based computer and machine vision.

Computer vision

Computer vision tasks include methods for , , and understanding digital images, and extraction of high-dimensional data from the real world in order to produce numerical or symbolic information, e.g. in the forms of decisions. Understanding in this context means the transformation of visual images (the input to the retina in the human analog) into descriptions of the world that make sense to thought processes and can elicit appropriate action.

Machine vision

Machine vision (MV) is the technology and methods used to provide -based automatic inspection and analysis for such applications as automatic inspection, process control, and robot guidance, usually in industry. Machine vision refers to many technologies, software and hardware products, integrated systems, actions, methods and expertise. Machine vision as a systems engineering discipline can be considered distinct from computer vision, a form of computer science.

Active-pixel sensor

An active-pixel sensor (APS) is an , which was invented by Peter J.W. Noble in 1968, where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as amplifiers. There are different types of APS, including the early NMOS APS and the now much more common complementary MOS (CMOS) APS, also known as the CMOS sensor.
