Abstract
A stand-alone module for localizing a surveying device installed with a stand above a ground mark. The module has at least one housing attached between the stand and the surveying device, a measuring camera unit, which is arranged and designed in such a way that when the module is mounted on a stand the ground mark can be detected in the field of view of the measuring camera unit, a power supply, an inclination sensor and a communication unit.
Claims15
A stand-alone module for localizing a surveying device installed with a stand above a ground mark, the stand-alone module comprising:
- a housing configured to be attached between the stand and the surveying device, the housing having a lower mounting plate for connecting to the stand and an upper mounting plate for connecting to the surveying device;
- a measuring camera unit configured such that when the stand-alone module is mounted on the stand the ground mark can be detected in a field of view of the measuring camera unit;
- a power supply;
- an inclination sensor determining an inclination of the stand-alone module with respect to a horizontal direction;
- a communication unit for communication with the surveying device or an external operating unit;
- a localization unit which calculates a location in relation to the ground mark and provides the location via the communication, the calculation of the location being based on:
- image information of the ground mark from the measuring camera unit or a visual pattern of a defined target plate in the image information, and
- inclination information from the inclination sensor.
A method for localizing a surveying device positioned on a stand above a ground mark with a stand-alone module which is attached between the stand and the surveying device, the method comprising:
- a recording of an image of the ground under the stand with a measuring camera in the stand-alone module;
- identifying a ground point in the image and surveying the ground point in the image;
- detecting an inclination value of the stand-alone module in at least two axes in relation to a horizontal or vertical direction with an inclination sensor in the stand-alone module;
- calculating a localization of the stand-alone module with respect to the ground mark based on measurement of the ground point in the image and of the inclination value, with a localization unit in the stand-alone module;
- directly or indirectly communicating a determined position or raw data for a position determined by the stand-alone module by means of a communication unit in the stand-alone module to the surveying device;
- and
- establishing a localization of the surveying device relative to the ground point with the localization provided by the stand-alone module.
