Stereo-Vision Algorithm Based on Bio-Inspired Silicon Retinas for Implementation in Hardware

چکیده
In this paper, we propose a silicon-retina-based stereo vision system, used for pre-crash warning or rather side-impact detection applications in vehicles. The bio-inspired silicon retina sensor is a new kind of sensor, which delivers data asynchronously and only if the intensity of the ambient light changes. Therefore, the amount of data that must be processed decreases significantly compared to standard CMOS or CCD imagers. The sensor uses an address-event representation (AER) protocol to transfer the event-triggered information. Concerning the special output characteristics of the imager, a novel approach regarding acquisition, storage, and matching of the data was implemented. The concept of the algorithm is specifically targeted and optimized for an implementation in hardware, e.g. on a Field Programmable Gate Array (FPGA).

Address-event Matching for a Silicon Retina Based Stereo Vision System
In this paper we present a stereo vision system based on silicon retina sensors. Derived from the human vision system, these bio-inspired silicon retina sensors are a new type of imagers. Conventional optical sensors capture images at a fixed frame-rate and deliver pixel information of the sensor chip at a certain point in time. In contrast, a silicon retina optical sensor provides only intensi...
متن کاملLow-level Stereo Matching using Event-based Silicon Retinas
This semester thesis examines the task of computing stereo image disparities using a binocular pair of event-based silicon retinas [1]. Unlike conventional video cameras, this silicon retina is asynchronous and event-based. It responds to reflectance change and thus the events primarily encode object movement. Therefore there is no global frame rate. Two different algorithms were devised to do ...
