A super-resolution algorithm for enhancement of FLASH LIDAR data

Abstract: A novel method for enhancement of the spatial resolution of 3-diminsional Flash Lidar images is being proposed for generation of elevation maps of terrain from a moving platform. NASA recognizes the Flash LIDAR technology as an important tool for enabling safe and precision landing in future unmanned and crewed lunar and planetary missions. The ability of the Flash LIDAR to generate 3-dimensional maps of the landing site area during the final stages of the descent phase for detection of hazardous terrain featu… Show more

“…However, a number of HDA algorithms have been proposed in the 1990's and early 2000's. These algorithms considered using descent images from electrooptical (EO) passive sensors in monocular and stereo configurations, as well as 3-D point clouds form active scanning and flash Lidar sensors [2,5,16,22,30,34,35]. More recently, technologies for automated detection of rocks and craters from EO imagery were selected by NASA's New Millennium program but a funding shortfall precluded further development [18,31,32].…”

“…Civilian and military organizations that carry out such operations could, for example, quickly deploy a swarm of small unmanned Short take off and Landing (STOL) craft equipped with HDA and thus having the ability to autonomously choose a safe landing site as close as possible to the target area. An example of efforts in this direction, specifically aimed at unmanned autonomous helicopter landing capabilities, is underway sponsored by the Office of Naval Research (ONR) under the Autonomous Aerial Cargo/Utility Systems (AACUS) program [5].…”

“…Therefore, methods in the spatial domain have become more popular in recent years, including iterative back projection (IBP) (Irani and Peleg 1991), projection onto convex sets (POCS) (Zhang and Zhou 2011), and a group of regularized variational methods (Park et al 2003;Ng et al 2007b;Zhang et al 2007, Zeng andYang 2013). Among these methods, Bulyshev et al (2011) attempted to employ a back projection (BP) method for the processing of multiple three-dimensional Flash LiDAR DEM data. However, this method has only been tested on simulated data, ignoring the possible inconsistency between multi-sensor and multi-scale DEMs.…”
