    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 system for measuring solder paste stencil aperture positions and sizes is provided. The system includes at least one camera configured to acquire images of the stencil and an alignment target. A motion system generates relative motion between the at least one camera and the stencil. A controller is coupled to and controls the motion system. The controller is configured to analyze the images to generate aperture information relative to the stencil. The aperture information is provided to automatically program a solder paste inspection system. Other features and benefits that characterize embodiments of the present invention will be apparent upon reading the following detailed description and review of the associated drawings.

    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 system for sensing a three-dimensional topology of a circuit board is provided. An illumination source generates patterned illumination from a first point of view. At least one camera acquires an image of the patterned illumination from a second point of view. A controller is coupled to the source, and to the at least one camera. The controller generates a height topology of the circuit board based on images acquired from first and second image detectors of the patterned illumination. The characteristics of the pattern illumination are modified based on knowledge of the circuit board to enhance the dynamic range of the sensor and to reject image defects caused by multipath reflections.

    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.
