Abstract:
1. A method for displaying a 2D image data set obtained using a 2D imaging device combined with a 3D range data set obtained using a 3D rangefinder device, comprising: providing a 3D range data set; providing at least one 2D image data set having a different resolution than the 3D range data set; representing the 3D range data set as a first displayed image; representing the at least one 2D image data set as at least a second displayed image; identifying corresponding features within the first displayed image and within the at least one second displayed image respectively; computing a 3D transformation between the 3D range data set and the at least one 2D image data set based on geometry of the identified corresponding features, such that geometric correspondence between the 3D range data set and the at least one 2D image data set is determined; representing the at least one 2D image data set as a third displayed image; and computing a 3D coordinate for a specified pixel of the third displayed image based on the previously computed 3D transformation and the 3D range data set.
