Optical range-finding systems which measure underwater vehicles operate within the visible spectral range.

Alternatively, you can measure the reflected light on the surface of the water.

Such calibration can be performed, for example, by measuring already known target points in the measurement environment.

The merchant- preacher might have traded in these fabrics and acquired for himself material to have some suits measured.

Confusion or unintentional duplicate measurement of points to be measured can thus be prevented.

Advantageously it is provided that the two optical sensors measure a single, common signaling device.

On measuring the reflective element with a laser beam, the latter can be simultaneously detected by means of the detector zones.

The position of probe 119 in the direction of movement is detected by an interferometer 114a whose two individual beams 117a and 118a (directly, or after two deflections at prisms 113a and 116a) measure the opposing body mirror 115a.

However, the estimation of the direction by means of triangulation when two or more sensors are used will be successful only if precisely the same object site is measured.

Also, instead of the angle measuring systems (15, 16) and (17, 18) for measuring the position of the probe in the horizontal plane, other measuring systems can be used: such systems, for example, that measure the position of the probe from at least two spaced-apart stationary positions.

The position of probe 119 in the direction of movement is detected by an interferometer 114a whose two individual beams 117a and 118a (directly, or after two deflections at prisms 113a and 116a) measure the opposing body mirror 115a.

Furthermore, proceeding from the setup position 4 of the surveying device 40 b, a respective absolute reference point position 23 can be produced, wherein this position can be variable in a mobile manner by an air vehicle 50, by measuring of the reference point 23 by the surveying device 40 b .

The position determination of the targeting unit 10 can also be performed by means of a surveying station, the targeting unit of which can measure and track the targeting unit 10 or a reflector arranged on the targeting unit 10 and can thus ascertain a distance and angle to the unit 10 .

When, however, a special disk is mounted as a brake disk on the axle between the wheels, then on account of the special and specified angular direction of the measurement axis it is possible also to measure this brake disk.

The unique linkage is possible since measuring a vehicle and capturing the image of the vehicle are linked actions that begin in known chronological correlation with respect to each other.

Measuring device for determining a leg length for measurement of stockings, in particular medical compression stockings, comprising a base plate with a foot-receiving surface and, arranged vertically thereon, a measurement board, wherein the measurement board (6), which can be mounted releasably on the base plate (2), is composed of a plurality of releasably connectable board sections (6 a, 6 b, 6 c, 6 d).

Furthermore, the laser tracker can be calibrated by measuring defined reference points on an object to be measured in an object coordinate system and this enables a measuring position of the scanning device relative to the object to be derived.

In particular, for measuring a target point or a reflector arranged on a surveying rod, an optical contact must be provided between surveying device and the reflector, i.e., a measuring beam can be aligned directly without beam interruption on a corresponding target.

For example, this can be effected by additional measurement of a fixed point position at a known height, this then being taken into account when deriving the fitted transformation parameters.

For this purpose, control data can be obtained from the reference information and the air vehicle can be flown to a defined target position by means of this control data, wherein the surveying device can already have been calibrated beforehand in a coordinate system by measuring points, the coordinates of which are known, and an exact position of the air vehicle in this coordinate system can be able to be determined therefrom.

The invention relates to a measuring device for determining a leg length for measurement of stockings, in particular medical compression stockings, comprising a base plate with a foot-receiving surface and, arranged vertically thereon, a measurement board.

To ensure that these measured relative positions acquire a relationship to the external reference system, in each case measurement of one or more reference points can now be effected, without observing an order, before, between or after the sequential measurement to the measuring points.

If the scanner 1 is positioned over the point 9001, it can for example also measure further points 9002, 9003 in order to associate the data items of the multiple scan thus obtained with one another in a subsequent setup at those further points.

For a use for aligning a laser scanner installed alongside a roadway, what is disadvantageous about this method, in particular, is that, for aligning the scanning plane, firstly the height of the transmitter relative to the roadway has to be known and secondly, with the two well-defined bodies, special aids are required, the arrangement and measurement of which are difficult in moving traffic.

With increasing installation height, the situation can then arise that reliable measurement is no longer ensured in the case of a horizontal alignment of the scanning plane, such that, in order to arrive at an optimum measurement range, a pitching angle dependent on the installation height has to be set, as a result of which the scanning plane forms a corresponding angle of less than 90° with the roadway surface.

Measurement device 192 may measure the retroreflectors 193, 194 and 195 one after the other, i.e. sequentially.
