Geodetic survey system having a camera integrated in a remote control unit

摘要

A survey system including a target unit that has a survey stick having a high-precision localizable target and a hand-held remote control unit. The remote control unit has an electronic graphical display and can be mounted on a holder on the survey stick such that the remote control unit is in a fixed position relative to the target fitted to the survey stick. The remote control comprises a camera for taking a camera image in a defined shooting direction. In addition, an image processing and evaluation unit with a data link to the position-finding unit and to the camera is provided which, from knowledge of the fixed relative position and of a defined shooting direction and also on the basis of the determined target position, can spatially relate image data from the camera to the targets in the coordinate system.

1. A survey system comprising:
a position determination unit for determining a target position in a defined coordinate system, and a mobile target unit for staking out and/or position determination of target points in the coordinate system, wherein the mobile target unit includes: a surveying pole, the lower end of which is configured to be brought into target point contact, a target which is configured to be fitted on the surveying pole and the target position of which is determinable with high precision; a handholdable remote control unit for the survey system, wherein the remote control unit includes an electronic graphical display and is attachable to a holder on the surveying pole and is—in the attached state—furthermore in a fixed position relationship with respect to the target fitted on the surveying pole; the remote control unit comprises a camera for recording a camera image in a defined imaging direction; and an image processing and evaluation unit having a data link to the position determination unit and the camera is provided, by which, with the aid of knowledge of the fixed position relationship and the defined imaging direction, and as a function of the target position determined, image data of the camera are brought into spatial relation with the target points in the coordinate system.
