摘要:
A system, apparatus, method, and computer program product for evaluating an object disposed on an upper surface of an object holder. At least one first frame representing a captured portion of the object is acquired, while the object holder is positioned at each of multiple locations. At least one second frame representing a captured portion of at least one other surface of the object holder is acquired, while the object holder is positioned at each of the locations. At least one spatial characteristic associated with the captured portion of the object is determined based on at least one of the acquired frames. Values of multiple optical markers captured in each second frame are determined, where at least two of the optical markers have different characteristics. At least one of coordinates associated with the values and an orientation of the captured portion of the at least one other surface are determined.

摘要:
A method and apparatus for forming an overall image of an object from a plurality of images. Each image includes three-dimensional data and color data and is segmented based on the color data to identify a first region with hard tissue and a second region with soft tissue. For each image, first and second weighting factors may be assigned. Points in the second region with a larger distance to a corresponding proximate part of the first region may have a smaller second weighting factor than a point with a smaller distance to a corresponding proximate part of the first region. The second weighting factor may be variable, with its value dependent upon a value of a first area section corresponding to the first region.

The invention relates to a method and a device for three-dimensional measurement of an object. The device includes a laser source for generating an illumination beam, a focusing optics for focusing the illumination beam on at least one measuring point on a surface of the object to be measured, a detector for detecting an observation beam reflected by the surface of the object, a confocal observation optics which allows only the observation beam that is focused on the surface of the object to pass through to the detector. The laser source includes multiple coherent laser elements, the laser elements simultaneously emitting illumination beams that are focused on multiple measuring points on the surface of the object, so that the laser elements are arranged to reduce the speckle effect in the 3D-image data generated by the measurement.
摘要:
The invention relates to a reference object (3) and a method for checking a measuring system (1), wherein a plurality of three-dimensional recordings (4, 8) of a reference object are recorded from different recording directions (5) by means of the measuring system (1). The reference object (3) has a closed shape, wherein each of the three-dimensional recordings (4) is registered with at least the preceding recording (4). In the case of a faulty calibration and/or in the case of a faulty registration, the individual recordings (4, 8) are deformed compared to the actual shape of the reference object (3), so that the deformation continues when assembling the individual three-dimensional recordings (4) to form an overall recording (54) and the generated overall recording (54) deviates in its dimensions from the dimensions of the reference object (3) as a result thereof. At least one object region (10) of the reference object (3) is measured twice, at the beginning of a circuit and at the end of the circuit, wherein a distance (55) is determined in the overall recording (54) between a first position of the object region (10) in a first recording at the beginning of the circuit and a second position of the object region (10) in a second recording at the end of the circuit.

The invention relates to a method and a device (20) for three-dimensional measurement of an object (6) using a confocal microscopy method comprising a laser source (21) for generating an illumination beam (3), a focusing optics (4) for focusing the illumination beam (3) on at least one measuring point (5, 23) on a surface of the object (6) to be measured, a detector (10) for detecting an observation beam (9) reflected by the surface of the object (6), a confocal observation optics (7), which allows only the observation beam (9) that is focused on the surface of the object (6) to pass through to the detector (10). The laser source (21) comprises multiple coherent laser elements (22), the laser elements (22) simultaneously emitting illumination beams (3) that are focused on multiple measuring points (5, 23) on the surface of the object (6), so that the laser elements (22) are arranged to reduce the speckle effect in the 3D-image data generated by the measurement.
摘要:
A method for optically measuring an object by means of an optical recording apparatus includes a triangulation method. A first shutter means is used to produce a first pattern and to project the first pattern as a first projection beam onto the object to be measured. At least one further shutter means is used to produce a further pattern and to project the further pattern as a further projection beam onto the object to be measured. The first pattern and the further pattern are passed back from the object as observation beams and are recorded by at least one recording means in order to obtain a three-dimensional data record of the object. The projected first pattern and the further pattern are recorded at the same time in at least one triangulation recording using the at least one recording means.

A method for triggering at least one restraint means, triggering signals from peripheral acceleration sensors being released by signals from centrally situated acceleration sensors. In this context, a release threshold is raised in the case of a detected misuse behavior, or the release for the triggering signals is blocked.
