Surveying device, method for surveying target object with the survey device and computer program product

Abstract

The invention relates to a surveying device, a method for surveying a target object with the survey device and a computer program product. The surveying device has a base for setting up the surveying device and a targeting unit, which is rotatable in relation to the base about two axes, and which defines a target axis or targeting a target object to be surveyed. The targeting unit has a first beam path for emitting optical radiation in the direction of the target object to be surveyed and a second beam path for receiving a component of the optical radiation, which is reflected from the target object, by way of an optoelectronic receiving element. In some embodiments, at least one of the beam paths, has an optical element, which is implemented having an optically transparent, deformable volume body, and which has at least one interface toward a medium having an optical index of refraction deviating from the volume body. The interface makes the optical reflective performance changes on at least two different directions by deformation of a plurality of electrical activation signals.

Description

technical field [0001] The invention relates to an optical mapping device, in particular a tachymeter, a laser scanner, or a laser tracker, and a method for mapping a target object with an optical mapping device. Background technique [0002] The devices of surveying technology operate in various forms based on optical measuring systems. Examples of surveying devices according to this type are eg disclosed in US6,873,407, CN201892533, US2011 / 080477, EP1081459, US2012 / 127455, WO2012 / 033892, WO2007 / 079600, WO2010 / 148525 or other patents. [0003] Typically, optical radiation is emitted from these devices in the direction of the target object to be mapped, the distance and angular position of the target object, ie polar coordinates are determined, which are then usually further processed. A component of the radiation emitted from the target object to be mapped is in this case reflected to the device, received there and converted into an electrical signal for distance determina...

AI Technical Summary

Problems solved by technology

Not only is the device design difficult due to the high number of optical components required, but also the alignment of all respectively participating components relative to each other (to be done during production) proves to be more difficult and complex

The probability also increases with the number of components that one of these components can be misaligned by internal or external influences and thus the device loses accuracy
