14 May 2012Foliage penetration by using 4-D point cloud data
Real-time awareness and rapid target detection are critical for the success of military missions. New technologies
capable of detecting targets concealed in forest areas are needed in order to track and identify possible threats. Currently,
LAser Detection And Ranging (LADAR) systems are capable of detecting obscured targets; however, tracking
capabilities are severely limited. Now, a new LADAR-derived technology is under development to generate 4-D datasets
(3-D video in a point cloud format). As such, there is a new need for algorithms that are able to process data in real time.
We propose an algorithm capable of removing vegetation and other objects that may obfuscate concealed targets in a
real 3-D environment. The algorithm is based on wavelets and can be used as a pre-processing step in a target
recognition algorithm. Applications of the algorithm in a real-time 3-D system could help make pilots aware of high risk
hidden targets such as tanks and weapons, among others. We will be using a 4-D simulated point cloud data to
demonstrate the capabilities of our algorithm.
