A method for compensating beam angle variation of a beam bundle of laser beams with respective beam angles includes generating the beam bundle using a diffractive optical element, determining a beam angle value from a beam angle of at least one laser beam of a first subset of the laser beams, detecting a light pattern projected by a second subset of the laser beams, and evaluating the light pattern. The evaluation is performed taking into account the beam angle variation of the beam angles of the second subset of the laser beams on the basis of the determined beam angle value.

An imaging system for capturing an object includes a plurality of light sources for illuminating the object and a plurality of optical sensors. The plurality of light sources emit light radiation and the plurality of optical sensors are arranged to detect light radiation reflected from the object.

Imaging system

A lighting devicehaving: a plurality of light sourcesarranged in a line; each of said light sourceshaving a condenser lensarranged in the optical pathof the respective light source, wherein said condenser lensesare designed such that light is focused at least in a first plane XZ; at least one cylinder lensin form of a Fresnel lens, arranged in the direction of the optical path behind the condenser lenseswherein said cylinder lensis designed such that light is focused in a second plane YZ, which second plane YZ is arranged traverse to the first plane XZ; and an optical diffuserarranged in the direction of the optical path behind the cylinder lens, wherein the optical diffuseris designed such that light is diverged and homogenized in the first plane XZ.

The invention relates to a measuring method for determining biometric data of human feet, comprising the following steps providing a reference object, which has at least one reference pattern, providing a freely moveable image recording device, automatically detecting the relative position and the alignment of the image recording device relative to the reference object using the at least one reference pattern, automatically recording of several images by the image recording device, wherein each individual image is only recorded, when the relative position and the alignment of the image recording device relative to the reference object corresponds to a triggering position predetermined for the respective image, determining biometric data of the at least one foot by means of the recorded images. Furthermore, the present invention relates to a measuring system as well as a pedestal for determining biometric data of human feet.

A method for measuring the height of an object, including projecting a light pattern having successive coded picture elements extending in a direction of a transversal axis onto the object by a light source. Each of the picture elements has at least one coding feature and the picture elements together define a code word. The picture element groups from a sequence of a predetermined number of successive picture elements each define individual partial code words, existing exactly once within the code word. Capturing the light pattern by a picture sensor arranged off-set to the light source. Determining the positions of the picture element groups and determining the height of the object the determined position of the picture element groups in comparison to a respective reference position.

Method and light pattern for measuring the height or the height profile of an object

Traffic monitoring apparatus with a housing, which has several longitudinal profiles, which are aligned parallel to a vertical axis H and which are arranged circumferentially around the vertical axis H and enclose an inner housing chamber, wherein at least one of the longitudinal profileshas an outer wall, forming the outer face, and an inner wall, forming the inner face, facing to the inner housing chamber

Traffic monitoring apparatus

A plurality of separate conveyings over each of which a single line camera is mounted and connected to a sensor processor, which itself is connected to a fast data network with a plurality of processing terminals. Because of the high resolution (up to 7000 picture elements per line) and a line scanning frequency of the order of up to 6000 hertz very large amounts of data are received, so in the preferred embodiment a high capacity data network is used, for example a 100 Mbit ethernet with a switching hub.
