US 2006/0038892 A1 · Method and imager for detecting the location of objects

Abstract

A device detects the location of objects in an environment by receiving an optical image and converting the optical image of the lost object into a color digital image. The device employs software to perform an analysis of the color digital image to detect the location of the one or more objects in the environment by using color and shape characteristics of the one or more objects. The software uses a range of the visible portion of the color space uniquely identified for the type of object in that environment and identifies those pixels in the color digital image that may be possible targets. Intensity of background and object size are used to exclude pixels as possible target objects.

Dependent claims

A method of detecting the location of an a stationary object in an environment having stationary objects, the method comprising:

defining a target color space uniquely identified for the type of object that is stationary based on observed R, G, B levels in a series of reference digital color images of the type of object that is stationary;
generating a color digital image of an environment;
determining whether there are a set of pixels in the digital color image of the environment that are within the target color space defined for the type of object that is stationary;
and
reporting the determination that there are a set of pixels within the target color space defined for the type of object that is stationary
wherein the set of pixels corresponds to the location of the stationary of object in the environment.
