technique employs the matching of image primitives rather than wire frames the user matches between two images one match for the original image and the other match is for synthesized image of the scene based on a 3d model and existing geo positioned images that are used to texture the model the match points can relate to the geometry such as the corners of a wire box or to texture features reference is now made to the drawings wherein like reference numerals are used to refer to like elements throughout in the following description for purposes of explanation numerous specific details are set forth in order to provide a thorough understanding thereof it may be evident however that the novel embodiments can be practiced without these specific details in other instances well known structures and devices are shown in block diagram form in order to facilitate a description thereof fig1 illustrates a computer implemented calibration system 100 the system 100 includes a visualization component 102 for presenting a semi transparent overlay 104 of image data 106 with model data 108 in a single view for an image registration process the system 100 can also include an interactive component 110 for directly manipulating model points of the model data 106 to corresponding image points on the image data 108.
