    摘要： A system for generating a three-dimensional height image of a reflective target includes an illumination source configured to generate a patterned illumination on the reflective target, and an imaging system configured to acquire an image of the patterned illumination on the reflective target, the illumination source and camera being aligned relative to the target such that the camera acquires a specular image of the patterned illumination. The system further including a controller coupled to the illumination source and the camera configured to generate a first height image of the target based on the acquired image, the first height image being used by the controller to determine a position, a height, and a tilt of the target and calculate an error function based on the determination to compensate the first height image for the calculated error.

    摘要： A method of determining dimensional information of a target surface includes generating a first point cloud corresponding to a first plurality of reconstructed surface points of the target surface generated by a first imaging system-illumination source pair of a phase profilometry system; generating a second point cloud corresponding to a second plurality of reconstructed surface points of the target surface generated by a second imaging system-illumination source pair of the phase profilometry system; generating an initial estimate of the target surface based on the first and second point clouds; and refining the initial surface estimate using positions of the first and second point clouds and geometry of the first and second imaging system-illumination source pairs to generate a final point cloud.

    摘要： A computer-implemented method of and system for measuring a three-dimensional surface are provided. The method includes projecting structured illumination on the surface and acquiring a plurality of sets of images. The sets of images are processed to obtain a plurality of point clouds. A spatial accumulator is defined. A first point cloud of the plurality of point clouds is combined with a second point cloud of the plurality of point clouds into the spatial accumulator. Spatial coordinates of the surface are generated based on the contents of the spatial accumulator.

    摘要： A system for generating a three-dimensional height image of a reflective test target includes an illumination source configured to generate a patterned illumination on the test target, an imaging system configured to acquire an image of the patterned illumination on the test target, and a variable focus optical system configured to cause the camera to image the test target with at least two distinct focus positions, the illumination source and camera being aligned relative to the test target such that the camera acquires a specular image of the patterned illumination. The system further including a controller coupled to the illumination source, the camera and the variable focus optical system, the controller being configured to generate a height image of the test target based on the acquired image of the patterned illumination using at least two distinct focal positions.

    摘要： A three-dimensional non-contact scanning system is provided. The system includes a stage and at least one scanner configured to scan an object on the stage. A motion control system is configured to generate relative motion between the at least one scanner and the stage. A controller is coupled to the at least one scanner and the motion control system. The controller is configured to perform a field calibration where an artifact having features with known positional relationships is scanned by the at least one scanner in a plurality of different orientations to generate sensed measurement data corresponding to the features. Deviations between the sensed measurement data and the known positional relationships are determined. Based on the determined deviations, a coordinate transform is calculated for each of the at least one scanner where the coordinate transform reduces the determined deviations.

    摘要： A system for sensing a three-dimensional topology of a circuit board is provided. An illumination source projects an illumination pattern from a first angle of incidence. A first camera acquires an image of the structured light pattern on the circuit board from a second angle of incidence. A second camera simultaneously acquires an image of the structured light pattern on the circuit board from a third angle of incidence, the third angle of incidence differing from the second angle of incidence. A controller is coupled to the illumination source and to the at least two camera devices. The controller generates a height topology of the circuit board based on images acquired from the at least two camera devices of the structure light illuminator.
