Tracking method and measuring system with laser tracker

摘要

The method involves providing an overview apparatus (13) with known position and orientation relative to a measuring beam (M). An illumination of a reflector (12) is performed using an illuminating unit (15) in regions of a device list, and a field of view of the overview apparatus is illuminated by the illumination unit. The overview apparatus is formed as an overview camera, and the data image coordinates of a reflector image (12') are registered by the overview camera. An extraordinary tracking mode is activated, when no measuring beam reflected by the reflector is detected. An independent claim is also included for a measuring system.
