Embodiment Construction

[0069] figure 1 and Figure 5 A hand-held auxiliary measuring device 50 according to the invention is shown for use in a system having a station for determining the position and orientation of the auxiliary measuring device for measuring surfaces of objects. The auxiliary measuring device 50 in this case has a body 62 on which the visible markings 52 are arranged in a marking region 58 in a defined spatial relationship relative to one another, so that these visual markings form a pattern.

[0070] Furthermore, the measuring probe 53 is arranged in a defined spatial relationship with respect to the pattern at the aperture 55 of the main body 62 , the measuring probe being formed here, for example, by a pin on which is arranged a sensor for tactilely touching the surface of the object. A sphere that physically touches the measurement point.

[0071] In addition, a first operating member 54 actuatable by the user (for example, an operating button that can be pressed) is provid...

Abstract

The invention relates to a handheld measuring aid for use with a six-degrees-of-freedom laser tracker. Some embodiments of the invention relate to a handheld measuring aid for use in a system having a station for position and orientation determination of the handheld measuring aid for surveying an object surface. The handheld measuring aid has in this case on a body, visual markings which are arranged in a defined spatial relationship, forming a pattern, on the body in a marking region, a measuring probe, which is arranged on an orifice of the body in a defined spatial relationship in relation to the pattern, for the object surface, an operating element, an electronic circuit for generating a measurement triggering signal occurring as a function of an actuation of the operating element, and wireless communication means for transmitting the measurement triggering signal to the station.

Description

technical field [0001] The invention relates to a hand-held auxiliary measuring device for use in a system for measuring surfaces of objects having a measuring station for determining the position and orientation of the auxiliary measuring device. Background technique [0002] Such industrial measuring systems have been known for a long time from the prior art for determining the coordinate position of points on a surface and by means of a hand-held auxiliary measuring device in conjunction with a measuring station (such as in particular 6 A laser tracker with four degrees of freedom) is formed by combining. [0003] Examples of such systems are described, for example, in patent literature publications WO1993 / 07443A1, WO1997 / 14015A1, WO2007 / 124009A2 or WO2007 / 124010A2, or also as products sold by Leica Geosystems AG. - Known form of laser tracker "AT901" and auxiliary measuring device "T probe". [0004] For this purpose, such hand-held auxiliary measuring instruments have...
