An Experiment on Detecting Moving Objects Using a Single Scene of QuickBird Data

Abstract

An experiment on detecting moving objects was made by the utilization of a single QuickBird scene. The observation time lag between panchromatic and multispectral images of QuickBird bundle product is around 0.2 seconds. This product can be considered to be two consecutive acquisition images covering the same area within the time lag, though the ground resolutions of those images are different. Applying this principle, moving objects, e.g. aircrafts, boats, vehicles, can be detected by the simple way using overlapping panchromatic and multispectral images in the same size and at the same coordinate. The distances of the target movements and the velocities can be obtained by the measurements of target displacements because they change their positions in this extremely short interval. This paper is to introduce a new method of high resolution satellite data application which has not been considered yet.
