Abstract:
1. A method for visualizing a scene, comprising: scanning the scene with a substance detector to detect a substance in the scene; tracking scanning positions of the substance detector in the scene with respect to a first frame of reference; storing data representing three-dimensional scanning positions of the substance detector in the first frame of reference; displaying a view of the scene from a second frame of reference; tracking changes in a relationship between the first frame of reference and the second frame of reference due to changes in position and orientation of the substance detector and/or the view of the scene; retrieving the data representing the three-dimensional scanning positions of the substance detector in the first frame of reference; transforming the data from the first frame of reference to the second frame of reference, taking into account the changes in the relationship between the first frame of reference and the second frame of reference; and augmenting the displayed view of the scene with graphical element data that represents the three-dimensional scanning positions of the substance detector in the second frame of reference.
