Abstract:
1. A method of enhancing two-dimensional range images rendered from three-dimensional streak tube imaging lidar (STIL) data that is generated by a STIL camera system, comprising the steps of: providing rendered range image data, wherein said rendered range image data comprises pixels of data that comprise an image; modifying said rendered range image data to compensate for jitter effects associated with the STIL camera system, wherein first interim range image data is created; modifying portions of said first interim range data indicative of background in an image formed by said first interim range data to compensate for CCD array effects and range intensity roll-off associated with the STIL camera system, wherein second interim range image data is created; applying a noise reduction routine to said second interim range image data to assign a revised intensity value to pixels of data from said second interim range image data failing noise criteria defined by said noise reduction routine, wherein third interim range image data is created; and applying a histogram clip routine to said third interim range image data, wherein enhanced range image data is created.
