Embodiment Construction

[0036] figure 1A total station 1 is shown as an exemplary surveying instrument tracking a movable object in an environment 4, which in this example is a survey pole 2 with a Retroreflector 3 on top. The surveyor 6 can use the pointing tip of the surveying rod 2 to point to any target point he wants to measure. In this example, the total station 1 is equipped with a tracking unit which can follow the retroreflector with the light emitted through the measuring axis 7 . The measurement axis 7 is the axis of the range finder arranged in the alignment unit. The tracking unit has a detection range which can surround or intersect the measuring axis, so that the tracking unit can detect generally distant objects aimed at with the measuring axis.

[0037] In the illustrated embodiment, the tracking unit comprises a target-seeking system integrated in the surveying instrument and comprising a target-seeking sensor and a light emitter designed to emit light having a characteristic wav...

Abstract

The invention relates to a surveying instrument, wherein a control unit of the surveying instrument is configured for executing a relocation functionality, in context of which the surveying instrumentis configured for determining first coordinates of a stationary target point, receiving a start signal, wherein the first coordinates of the stationary target point are associated with the start signal, in response to the start signal, controlling a first actuator and a second actuator of the surveying instrument in such a way that the stationary target point remains within a detection area of atracking unit of the surveying instrument, determining second coordinates of the stationary target point, receiving an end signal, wherein the second coordinates of the stationary target point are associated with the end signal, and based at least in part on the first and second coordinates of the stationary target point, determining a relative pose of the surveying instrument with respect to a first setup location and a second setup location, wherein the first setup location is associated with the first coordinates and the second setup location is associated with the second coordinates.

Description

technical field [0001] The present invention relates to a surveying instrument and a method of repositioning a surveying instrument. Universal surveying instruments are, for example, total stations, tachymeters, theodolites or laser trackers and belong to the field of geodesy and / or metrology. Background technique [0002] In a typical survey or stakeout procedure, a surveyor uses a surveying instrument to aim at a set target or target point to be surveyed, and then precisely measures the position of the target or target point. Widely used targets are prisms, mirrors, tape and target plates, where such targets typically represent stationary target points of the environment, such as room corners, window corners, wall outlets, water pipes, or any other significant geometric feature . However, general purpose survey instruments are also designed to directly survey such points in the environment. Using a telescope or electronic viewfinder makes it easier to manually aim at a ...
