Cooperative optical-imaging sensor array

摘要

An apparatus and method for providing image primitives, such as edge polarity, edge magnitude, edge orientation, and edge displacement, and derivatives thereof, for an object are described. The data are obtained substantially simultaneously and processed in parallel such that multiple objects can be distinguished from one another in real time.

1. A method for obtaining image features from an object illuminate solely by ambient light, comprising the steps of:
receiving optical signals from the object on at least two optical sensors having overlapping fields of view within which at least a portion of the object is located, and from which analog outputs are generated; simultaneously receiving the analog outputs from the at least two optical sensors responsive to the optical signals; and generating image features from parallel analog outputs.
