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.

Measurement method for a surface-measuring measuring machine

A method of operating an articulated arm CMM is provided. One or more coordinates on an object can be measured with the articulated arm CMM. At least one of the encoders can then be at least partially powered-off. The encoder can then be powered on and one or more coordinates on the same object can be measured without recalibrating the encoder.

CMM with improved sensors

A system is disclosed that comprises a camera module and a control and evaluation unit. The camera module is designed to be attached to the surveying pole and comprises at least one camera for capturing images. The control and evaluation unit has stored a program with program code so as to control and execute a functionality in which a series of images of the surrounding is captured with the at least one camera; a SLAM-evaluation with a defined algorithm using the series of images is performed, wherein a reference point field is built up and poses for the captured images are determined; and, based on the determined poses, a point cloud comprising 3D-positions of points of the surrounding can be computed by forward intersection using the series of images, particularly by using dense matching algorithm.

Surveying system

Some embodiments described herein relate to a measuring system for automated measurement of an object and detection of differences between features of the object and CAD data of the object. The measuring system may include a measuring device having a distance meter for measuring a position of at least one remote target point, a local computer terminal that is connected to or part of the measuring system, an assigned memory unit for storing the data base comprising the CAD data and an assigned set of measurement software program for controlling the measuring system. In some embodiments, the stored CAD data of the object comprise typical dimensions and tolerances of the features of the object and the assigned set of measurement software programs for controlling the measuring system comprises an optimization algorithm for the measurement of each feature.

Measuring system and method for automated measurement of an object

A coordinate measuring machine () for determining at least one spatial coordinate of a measurement point of an object () to be measured, comprising a base () and a drive mechanism, adapted to drive a probe head () in a manner such that the probe head () is capable to move relative to the base () for approaching a measurement point, characterized by a first range camera () having a range image sensor with a sensor array, wherein the range camera () is adapted to be directed to the object () for providing a range image () of the object (), and wherein range pixels of the range image are used for creating a point cloud with 3D-positions of target points of the object (), and a controller, adapted to control the drive mechanism on the basis of 3D-positions of the target points.

Coordinate measuring machine having a camera

A volume determining method for an object on a construction site is disclosed. The method may include moving a mobile camera along a path around the object while orienting the camera repeatedly onto the object. The method may include capturing a series of images of the object from different points on the path and with different orientations with the camera, the series being represented by an image data set; performing a structure from motion evaluation with a defined algorithm using the series of images and generating a spatial representation; scaling the spatial representation with help of given information about a known absolute reference regarding scale; defining a ground surface for the object and applying it onto the spatial representation; and calculating and outputting the absolute volume of the object based on the scaled spatial representation and the defined ground surface.

Method and system for volume determination using a structure from motion algorithm

In some embodiments, an articulated arm coordinate measurement machine can include a plurality of transfer members and a plurality of articulation members connecting the plurality of transfer members to each other to measure an angle between the transfer members. The machine can additionally include at least one coordinate acquisition member positioned at an end of the articulated arm. Further, the machine can include a harness connected to at least one of the group consisting of the transfer members and the articulation members to support at least a portion of the weight of the transfer members and the articulation members. The harness can also be configured to mount to a human.
