摘要： A reality capture device configured to perform a measuring process for generating a digital representation of an environment comprising a body defining a first axis, and an imaging unit with one or more 2D cameras configured to provide 2D image data of the environment. The device comprises a ToF camera arrangement configured for capturing 3D point-cloud data of the environment and comprising at least two time-of-flight cameras, wherein each time-of-flight camera comprises a sensor array and one or more laser emitters, the sensor array of each of the time-of-flight cameras having an optical axis and being configured to receive reflections of light pulses emitted by the one or more laser emitters of the respective time-of-flight camera, the time-of-flight cameras being arranged around the first axis so that each sensor array has one or two other sensor arrays as a neighbouring sensor array.

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： An industrial or geodetic surveying device with a scan functionality including an alidade rotating about a standing axis and a telescope unit with a beam exit for a laser measuring beam. The telescope unit is mounted on the alidade and is movable in a tilting motion about an elevation axis substantially orthogonal to the standing axis. The scan functionality comprises a scan sequence with an angular velocity of the alidade around the standing axis, wherein during the scan sequence the alidade is in a continuous revolving motion with mainly constant angular velocity about the standing axis, and the angular velocity of the alidade is faster than half of the angular velocity of the tilting motion of the telescope unit about the elevation axis.

摘要： In one example, a method may include receiving one or more laser scan of a scene, receiving two or more camera images of the scene, determining one or more decision regions where the camera images are different from one another, detecting edges of the decision regions where the camera images are different from one another, comparing the decision regions where the camera images are different from one another inside of the detected edges with a corresponding region in the laser scan to determine which of the camera images includes a desired region that more closely corresponds to the laser scan, and generating a corrected image including the desired region that more closely corresponds to the laser scan.

摘要： A six DOF measurement aid module for determining 3D coordinates of points to be measured of an object surface, comprising a laser tracker for determining the position and orientation of the six DOF measurement aid module. The six DOF measurement aid module has a body comprising an object coupling device with an object interface, configured to couple, via the object interface, alternatively both a handle to the body with a fixed pose and the body to a mobile platform with a fixed pose, a sensor attachment coupling device with a sensor interface-configured to couple alternatively both a sensor attachment effecting non-contact measurement and a sensor attachment effecting tactile measurement to the body with a fixed pose via the sensor interface, and visual markings, which are arranged in a defined spatial relationship in a manner forming a pattern in a marking region on the body.

摘要： A coordinate measuring and/or stake out device can be designed for being hand-held (one-handed), free carriage and movement by a user. A position giving means is for determination of an actual translational position of the device using an external position reference and an orientation giving means for determination of an actual rotational position of the device, such that the actual position of the device with respect to all six degrees of freedom of the device can be determined. A radiation source is for generation of a radiation beam as measuring and/or marking beam for measuring and/or visually marking of an object point. A beam steerer is for automatic steering of an alignment of the beam, whereby the beam which differ in the manner of automatic steering the beam alignment.
