ABSTRACT
In this paper, we describe efforts made to implement multiperspective mosaicking of infrared and color video data for
the purpose of under vehicle inspection. It is desired to create a large, high-resolution mosaic that may be used to
quickly visualize the entire scene shot by a camera making a single pass underneath the vehicle. Several constraints are
placed on the video data in order to facilitate the assumption that the entire scene in the sequence exists on a single
plane. Therefore, a single mosaic is used to represent a single video sequence. Phase correlation is used to perform
motion analysis in this case.
Keywords: mosaic, multiperspective, panoramic, phase correlation, infrared.
1. INTRODUCTION
Traditionally, the inspection of the underside of vehicles for dangerous materials (e.g. explosives or other types of threats)
prior to entry to sensitive areas was carried out using the mirror-on-a-stick method. This method does not work effectively
in low lighting conditions, and it is difficult to obtain a quick yet complete inspection of the entire underside of a vehicle
using this method. A solution to this problem has been devised that uses a camera mounted on a mobile platform. This
