Title:
ENHANCED CONTRAST FOR OBJECT DETECTION AND CHARACTERIZATION BY OPTICAL IMAGING
Document Type and Number:
Japanese Patent JP2016186793
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide imaging systems that improve object recognition by enhancing contrast between an object and background surfaces visible in an image.SOLUTION: An image capture and analysis system 100 for identifying objects of interest in an image scene 112 comprises: at least one camera 102, 104 oriented toward a field of view; at least one light source 108, 110 disposed on a same side of the field of view as the camera and oriented to illuminate the field of view; and an image analyzer 106 coupled to the camera and the light source(s). The image analyzer may be configured to operate the camera(s) to capture a sequence of images including a first image captured at a time when the light source(s) are illuminating the field of view, identify pixels corresponding to the object 114 rather than to the background, and based on the identified pixels, construct a 3D model of the object, including a position, a shape and a cross section of the object, to geometrically determine whether it corresponds to the object of interest.SELECTED DRAWING: Figure 1
