Abstract
A plurality of images are captured by an image capturing device that is an integral part of the mobile data collection platform from at least two different perspectives that depict a point of interest in a scene. Coincident with capture of each of the plurality of images, orientation information is obtained via orientation sensors of the mobile data collection platform, a position fix of an antenna associated with the mobile data collection platform is determined, and a position of an entrance pupil of the image capturing device is calculated. Scale information associated with at least one of the images is captured. Scene data comprises the images, the orientation information and the entrance pupil positions. A three dimensional position of the point of interest at the scene is determined based on photogrammetric image processing of the scene data.
