Abstract
Methods and apparatus which enable use of augmented vision in survey procedures and related work. Virtual objects are presented to an operator on a see through display. Some of the objects correspond with real objects in the operators field of view at any instant and others may provide interactive functions for the operator. The operator eye positions are determined using measurements from a remote positioning system such as GPS, an operator head orientation sensing system, and knowledge of head geometry. Positions and attributes of real objects are stored in a database memory carried by the operator. The operators field of view is continuously determined and images of the real objects are generated from database information by a rendering system. The images are presented on the see through display as virtual objects. Numerous functions may be provided for the operator using virtual interactive objects, depending on the work at hand. Functions to assist navigation around a site, measurement of new survey points, virtual entry of control commands, site checking, and survey calculations such as intersections and offsets may be provided. One adaptation of the augmented vision system r…
