A field test has been performed with the scanning mobile laser radar system Rapid Surveyor which was rented from Infoterra Ltd2. Rapid Surveyor is based on an Optech Lynx [1]. The test were performed in May 2009 and arranged by SWEDEC. The purpose was to evaluate the potential to use this type of laser scanner with high resolution for detection of IED and similar objects. A road section at Norra Kulla outside Eksjö, with a length of about 1.9 km, was scanned. The recordings during the first day were performed without targets. SWEDEC then arranged a change of the scenario, in the shape of interpretation of IED's, after which the acquirements continued. The acquirements were performed in three velocities (approx. 10, 20 and 30 km/h). Optech Lynx cannot detect explosive materials; instead the detection is based on changes in the geometry. Change detection was done by calculating some simple features, e.g., point density in a smaller volume (cube) and nearest-neighbour distance. The results were promising, but it can be noted that bushes and tree branches (in particular the outer parts) can result in non-negligible "change score", caused by wind movement of the branches, and the laser beam hitting different parts of the vegetation in the two recording instances. Further development of the method could include filtering of (local) shape and automatic size estimation of detected (suspicious) objects. The method used for change detection was implemented in Matlab; it is estimated that optimization of the code and implementation on a more suitable platform could meet realistic requirements for real-time processing.
