Image processing sensor systems

摘要

An image processing sensor system functions as a standalone unit to capture images and process the resulting signals to detect objects or events of interest. The processing significantly improves selectivity and specificity of detection objects and events.

1. A method of image-based object detection, comprising steps of:
identifying an object of interest having a plurality of discrete characteristics; selecting one or more of the discrete characteristics of the object of interest; collecting images of the object of interest that represent the one or more selected characteristics of the object of interest, electronically processing the collected images on a first processing station to produce a results key on a first processing station; representing characteristics of the object of interest in a quantified state that is associated with a predictive confidence for presence of the object of interest; transferring the results key to an image capture and processing device that is remote from the first processing station; repeatedly using the results key at the image capture and processing device to analyze sample images collected by the image capture and processing device to determine if the object of interest is represented in the sample images, this determination being made by determining if one or more selected characteristics of the object of interest are contained in the sample image; and conditionally producing an output signal to drive a secondary system for action appropriate to detection of the object of interest when one or more selected characteristics of the object of interest are present in the sample image, wherein the results key is dedicated to a single object of interest and the image capture and processing device operates on a standalone basis without further exchanging data with the first processing station as the image capture and processing device repeatedly uses the results key to analyze sample images for the presence of the object of interest.
