Abstract
Real-Time Mapping of Laser Rangefinder to Photograph in ArcMap
Track: Surveying
Author(s): Lionel White, Carlos Aiken, Mohammed Alfarhan, Jarvis Cline
Laser Sketch is an ArcGIS/ArcMap tool which maps in real-time the points measured by a non-imaging total station or laser range finder to their proper location in a photograph. A camera is characterized for lens distortion and the distortion parameters stored in Laser Sketch. A photograph of the target is taken and loaded into Laser Sketch. Four tiepoints between the photograph and the target are identified and measured. The photograph is oriented to the target in Laser Sketch and all subsequent shots appear directly on the photograph. There is no need to distortion correct the photograph in the field. The points are saved as a point shapefile with the XYZ coordinates of the points saved in separate fields of the attribute table. 3D analysis of the object that was surveyed, such as distance or volume, can be performed using the XYZ values stored in the attribute table.
