Embodiment Construction

[0049] Figure 1A and Figure 1B Shown is a portable measuring device for non-contact measurement of the distance z to a target object 200, for example at Figure 3A and Figure 3B The target object is exemplified in the Figure 5 The spacing z is further explained in . Figure 1A is a plan view of the operation surface of the housing 10 of the measuring instrument 100, Figure 1B is a side view of the housing 10 - schematically showing the constituent components of the gauge 100.

[0050] The housing 10 of the measuring device 100 , for example in the form of a laser distance meter, is designed for portable use - currently slightly larger than the size of a hand and has a corresponding feel, possibly ergonomic design; Even so, the housing 10 is illustrated as having a rectangular shape for simplicity. A distance measuring device 20 in the form of a laser distance measuring unit with optical measuring beam 1 is arranged in housing 10 . exist Figure 2A and Figure 2B A...

Abstract

The invention relates to a measuring device for noncontact measurement of distances to a target object, including a housing; a distance measuring unit situated in the housing uses an optical measuring beam, with the aid of which the distance between a reference point and at least one measuring point on a target object is measurable without contact; a photoelectric image acquisition unit situated in the housing having a viewfinder and camera lens situated in the housing as well as an image path connecting them for detecting target points of the target object, an image processing unit and a control and computation unit with the aid of which the image of the image processing unit is displayable. The image processing unit defines target points pixels in exactly one single photoelectric image, the control and computation unit allocating the distance of the reference point to the measuring point to at least one of the pixels, the allocation available for further processing.

Description

technical field [0001] The invention relates to a measuring device according to the preamble of claim 1 , in particular in the form of a portable tool, for the non-contact measurement of distances on a target object. The invention also relates to a method according to the preamble of claim 17 . Background technique [0002] A measuring device of the type mentioned at the outset can be used in particular as a portable distance measuring device, for example provided with a suitably designed laser measuring unit. [0003] In most cases, the non-contact measurement of the distance to a target object uses optical measuring beams, for example laser beams. In principle - independent of the measuring beam used - various distance measurement methods are known, for example non-contact measurement of the distance to a target object using transit time determination, phase measurement or laser triangulation . For the conversion of this or a similar method, the housing of the measuring...
