Three=dimensional surveying and determination of bounded travel path of vehicle esp. construction unit e.g. earth compactor

摘要

The surveying and travel path determination involves determination of the standing places of auto-theodolites (16L,16R), related to a locally fixed coordinate system associated with the terrain (12). The positions of the bearing marker (14) mounted on a vehicle (10), in the coordination system are computed using the known triangulation computing method at discrete intervals. The computed positions are recorded. The two self-aligning theodolites, with CCD cameras controlled by a computer (20), are mounted at a selected height above the terrain at any place. The standing places of the theodolites are determined with reference to a locally established coordinate system, associated with the terrain.
