Автор: Charles Mondello, Frank D. Giuffrida, Robert L. Gray, Stephen L. Schultz
Принадлежит: Individual

A computerized system for displaying and making measurements based upon captured oblique images. The system includes a computer system executing image display and analysis software. The software reads a plurality of captured oblique images having corresponding geo-location data and a data table storing ground plane data that approximates at least a portion of the terrain depicted within the captured oblique images. The executed software causes the computer system to receive a starting point selected by a user, receive an end point selected by the user and calculate a desired measurement between the starting and end points dependent upon the geo-location data and ground plane data. The desired measurement is selected from a group consisting of a distance measuring mode, a height measuring mode, and a relative elevation measuring mode.

To make it easy to recognize that pixel resolving power is changed during photography operation. A first camera and a second camera photograph two perspective images. A pixel resolving power calculation section 31 calculates pixel resolving power for photographing the two perspective images, based on a focal length, a base length, an object distance and a pixel size. In a reference pixel resolving power memorizing section 54 , reference pixel resolving power is memorized. In a display section 25 , the calculated pixel resolving power is displayed. A display control section 52 performs normal display of the pixel resolving power when the pixel resolving power is maintained to be no less than reference pixel resolving power, and performs highlighting display of the pixel resolving power when the pixel resolving power became a value lower than the reference pixel resolving power during photography operation.

A method for automatically steering mosaic cut lines along preferred routes to form an output mosaic image includes creating an assignment map corresponding to the output mosaic image where each pixel has an initial designation of unassigned; marking each pixel of the assignment map that intersects the preferred routes as being a Preferred Cut Line pixel to divide the Assignment Map into one or more regions; searching for each region to locate one or more source images that cover that region; and using a Selection Heuristic or Pairing Heuristic to determine quality of coverage. The Preferred Cut Line pixels are redesignated to match the image assignments of their bounded regions, and the output mosaic image is formed by contributing pixel values from the source images based upon the designations set forth in the assignment map.

Systems, methods and devices for use with unmanned aerial vehicles (UAV). A central controller is coupled to the autopilot system for a UAV. Navigation is implemented by using two GPS antennas and obtaining a difference between the locations from these two antenna to arrive at a high precision bearing or direction of travel. This single GPS derived bearing is used to trigger all the various subsystems on the UAV for imaging or mapping. Areas and locations to be mapped and imaged are determined by geolocation and mapping and imaging equipment are triggered based on the single GPS signal derived from the two GPS antennas. To reduce vibration effects on navigational and imaging or mapping equipment, these are positioned as close as possible to the vehicle's center of gravity and are deployed in a shielded box on vibration isolation mounts.
