VISIBLE LIGHT IMAGE WITH EDGE MARKING FOR ENHANCING IR IMAGERY

摘要

The invention relates generally to edge detection and presentation in thermal images. Infrared and visible light images comprising at least partially overlapping target scenes are analyzed. An edge detection process is performed on the visible light image to determine which pixels represent edges in the target scene. A display image is generated in which some pixels include infrared image data and in which pixels corresponding to edges in the visible light image include a predetermined color and do not include corresponding infrared image data to emphasize edges. Edge pixels in the display image can include exclusively the predetermined color, or in some examples, a blend of a predetermined color and visible light image data. Methods can include replacing one or the other of visible light edge pixels or corresponding infrared pixels with the predetermined color before combining the visible light and infrared image data to create a display image.

主权项

1. A non-transitory computer readable medium containing executable instructions causing one or more processors to perform a method of creating an infrared image of a scene that emphasizes the locations of visible edges, the method comprising:
receiving visible light (VL) image data associated with a plurality of VL pixels indicative of a VL image of a target scene; receiving infrared (IR) image data associated with a plurality of IR pixels indicative of an IR image of the target scene, each IR pixel having a corresponding one or more VL pixels indicative of the same portion of the target scene; determining which VL pixels correspond to edges in the VL image data and considering such pixels as VL edge pixels; and generating display image data associated with a plurality of display pixels, each display pixel having corresponding VL and IR pixels that correspond to the same portion of the target scene as such display pixel; wherein some of the display pixels include IR image data associated with corresponding IR pixels, and display pixels corresponding to VL edge pixels include a predetermined color and do not include IR image data associated with corresponding IR pixels in order to emphasize the location of edges in the display image data.
