摘要： The invention relates to a method for enhancing images for metrological applications. The method comprises the steps: 1) providing a geometric correction image having an image geometric correctness higher than the processed image geometric correctness and showing at least a part of the scene of interest, and 2) at least partially reducing the loss of initial metrological information in the distorted metrological information by fusing the enhanced image with the geometric correction image.

摘要： A laser-scanning method may include obtaining scan data captured by a laser scanner in which the laser scanner includes a first private key that uniquely corresponds to the laser scanner. The laser-scanning method may include obtaining a first digital signature corresponding to the obtained scan data that is generated based on the scan data and the first private key. The laser-scanning method may include validating the first digital signature using a first public key that corresponds to the first private key and generating a report that summarizes results of the validating. The laser-scanning method may include transforming and aggregating, by a scan data aggregator, the scan data as aggregated scan data and generating a second digital signature corresponding to the aggregated scan data. The second digital signature may be generated by signing hashes corresponding to the aggregated scan data using a second private key corresponding to the scan data aggregator.

摘要： A distance measuring device comprising an optical transmitter channel for transmitting laser light along a transmitter path and an optical reception channel for receiving laser light along a reception path. At least one optical element including a glass part with a coated surface is positioned in the optical transmitter channel or in the optical reception channel. The glass part includes a glass pane with a thickness below 0.3 mm, with a peripheral edge and with a coating on at least one of the two surfaces, and a ring element. The glass pane is adhesively connected to an end face of the ring element. This distance measuring device shows reduced measuring artefacts and/or reduced optical aberration effects and/or a reduced weight.

摘要： Measurement method where a code projection which is dependent on a three-dimensional position of a code carrier relative to a sensor arrangement is generated on a sensor arrangement, and at least part of the code projection is captured. An angular position of the code carrier with reference to the defined axis of rotation is ascertained and a current measurement position of the measurement component relative to a base is determined, wherein, a position value for at least one further degree of freedom of the code carrier relative to the sensor arrangement is ascertained on the basis of the code projection and is taken into account to determine the current measurement position, and a relative position of the connecting element with respect to the holder and/or the deformation thereof is determined from the position value in the form of a change in shape or size.

摘要： A laser scanner and a system with a laser scanner for measuring an environment. The laser scanner includes an optical distance measuring device, a support, a beam steering unit rotatably fixed to the support which rotates around a beam axis of rotation. The beam steering unit includes a mirrored surface which deflects radiation used in the optical distance measurement and an angle encoder for recording angle data. The optical distance measurement is performed by a progressive rotation of the beam steering unit about the beam axis of rotation and the continuous emission of a distance measurement radiation, the emission being made through an outlet area arranged in the direction of the mirrored surface on the support, the receiving optics for receiving radiation are arranged on the support, and wherein the outlet area has a lateral offset with respect to the optical axis of the receiving optics.
