Comparison of 2D and 3D displays and sensor fusion for threat detection, surveillance and telepresence

Visible, infrared (IR) and sensor-fused imagery of scenes that contain occluded camouflaged threats are compared on a two dimensional (2D) display and a three dimensional (3D) display. A 3D display is compared alongside a 2D monitor for hit and miss differences in the probability of detection of objects. Response times are also measured. Image fusion is achieved using a Gaussian Laplacian pyramidal approach with wavelets for edge enhancement. Detecting potential threats that are camouflaged or difficult to see is important not only for military acquisition problems but, also for crowd surveillance as well as tactical use such as on border patrols. Imaging and display technologies that take advantage of 3D and sensor fusion will be discussed.
