Apparatuses, systems and methods associated with a metrology system for high-speed, non-contact coordinate measurements of parts are disclosed herein. In embodiments, the metrology system includes a metrology bridge to be coupled to a measurement assembly. The measurement assembly may include a stage moveable across multiple independent axes. The bridge may include a housing, mounting members coupled to the housing, and a plurality of sensors mounted within the housing. The mounting members may rotatably couple the housing to the measurement assembly. Further, sensor elements of the plurality of sensor devices may be aligned along a length of the housing and may be directed out of the housing.

A measurement device is provided. The measurement device comprises a guide light source unit, an imaging unit, and a measurement unit. The guide light source unit is configured to output guide light and to continuously irradiate a measurement surface at a plurality of measurement reference points with said guide light. The measurement reference points are each at one end of the distance between two points to the measurement surface. The imaging unit is configured so as to capture a spot of guide light at the measurement surface at a first measurement reference point. The measurement unit is configured to calculate the slope of the measurement surface on the basis of the shape of the captured spot, and to calculate the depth of a second measurement reference point at an instance following the first measurement reference point on the basis of the calculation of the slope.

A six-DOF probe includes a retroreflector, a collection of target lights, and a stylus having a probe tip. A laser tracker measures a distance, a first angle, and a second angle to the retroreflector and captures an image of the illuminated target lights. A processor determines the three-dimensional coordinates of the probe tip based at least in part on the measured distance, measured first angle, measured second angle and on a central portion of the captured image, the size of the central portion based at least in part on the measured distance.

A system includes a first light source that emits a beam of light; an electrical modulator that imparts a time-varying modulation on the beam of light; a beam- shaping system that shapes the beam of light and projects the shaped beam of light onto an object; an image sensor that captures the beam of light reflected from the object; and processors that determine three-dimensional (3D) coordinates of points on the object.

A system includes a handheld unit having a light source, an image sensor, one or more first processors, an Ethernet cable, and a frame. The light source projects light onto an object, and the image sensor captures an image of light reflected from the object. One or more first processors are directly coupled to the frame. An accessory device has one or more second processors that receive data extracted from the captured image over the Ethernet cable and, in response, determine three-dimensional (3D) coordinates of points on the object. The accessory device also send electrical power over the Ethernet cable to the handheld unit.

A device for determining a dimension of a tool having a cutting edge includes a first light source configured to emit light parallel to a first axis, an image sensor which is associatable with a second axis extending orthogonally to the image sensor and an analyzing unit. The first axis and the second axis are inclined relative to each other. The device is configured such that the light emitted from the first light source is reflectable by the cutting edge of the tool in such a way that light spots arranged in a line on the image sensor are generatable by the reflected light. The analyzing unit is configured to determine positions of the light spots. The dimension of the tool is determinable based on the positions of the light spots.

An optical measuring device includes at least one optical sensor configured for optical capture of at least one measurement object at multiple image recording positions. The optical measuring device includes at least one display device configured to display, for multiple predetermined and/or determinable image recording positions, in each case a schematic representation of an image to be recorded at the respective image recording position. The optical measuring device includes at least one data processing unit and at least one interface. The interface is configured to provide at least one item of manipulation information to the data processing unit. The data processing unit is configured to, based on the manipulation information, adapt at least one of the image recording position and an image recording parameter of at least one of the images to be recorded.

An optical position measuring device for recording a relative position of two scales includes the scales. The longitudinal extents of the scales are oriented parallel to a first and second measuring direction. A horizontal plane of movement is spanned by these measuring directions. A light source is configured to emit an illumination beam that is split into at least two sub-beam bundles at the first scale. The sub-beam bundles subsequently impinge on the second scale, which is tilted about the direction of the longitudinal extent thereof relative to the horizontal plane of movement, and are back-reflected to impinge again on the first scale and are recombined there such that a resulting signal beam is subsequently propagated toward a detection unit, via which phase-shifted scanning signals are generatable with respect to a relative movement of the scales along a third perpendicular measuring direction and the first or second measuring direction.

A method including determining with a three-dimensional (3D) measuring instrument 3D coordinates of an object for each of a plurality of poses of the 3D measuring instrument; capturing with a camera first- and higher-order diffraction components of markers near or on the object, the camera having a diffractive optical element (DOE), a lens, and a photosensitive array; and registering with a processor the determined 3D coordinates based at least in part on the determined 3D coordinates and on the imaged zero- and higher-order diffraction components.

A 3D measuring equipment and a 3D measuring method are provided. The 3D measuring equipment includes a base, a fixture, a measuring device, and a controller. The fixture is disposed on the base for an object to be measured to be disposed thereon. The fixture has a plurality of rods. The heights of the rods are adjustable. The measuring device is installed on the base and is movable relative to the fixture. The controller is connected to the measuring device and the fixture and configured to perform the following. The heights of the rods are adjusted according to 3D model data of the object to be measured to support the object to be measured. The measuring device is driven to move relative to the fixture to measure the object to be measured.
