3D TERRAIN MAPPING SYSTEM AND METHOD

摘要

A terrain mapping system includes an aerial system including at least one camera configured to capture a plurality of aerial images of an area and transmit the plurality of aerial images to an image database, a plurality of machines each having a ground control point (GCP) disposed thereon, and each being configured to periodically record a global location of the GCP in a location history database, and a mapping unit configured to construct a preliminary three-dimensional (3D) terrain map based on the plurality of aerial images, detect at least one GCP within at least one aerial image, determine an estimated global location and an accurate global location of the at least one GCP, and calibrate the preliminary 3D terrain map based on the estimated global location and the accurate global location of the at least one GCP.

1. A terrain mapping system, comprising:
an aerial system comprising at least one camera configured to capture a plurality of aerial images of an area and transmit the plurality of aerial images to an image database; a plurality of machines each having a ground control point (GCP) disposed thereon, and each being configured to periodically record a global location of the GCP in a location history database; and a mapping unit in communication with the image database and the location history database, and configured to:
retrieve the plurality of aerial images from the image database;construct a preliminary three-dimensional (3D) terrain map based on the plurality of aerial images;detect at least one GCP within at least one aerial image;determine an estimated global location of the at least one GCP in the preliminary 3D terrain map;determine an accurate global location of the at least one GCP;calibrate the preliminary 3D terrain map based on the estimated global location and the accurate global location of the at least one GCP; andoutput the calibrated 3D terrain map.
