  • Patent number: 11543639
    Abstract: Dual mode imaging systems and methods for macroscopic and microscopic imaging using the same optical imaging system (OIS). The various embodiments enable controllable and/or automated switching between macroscopic imaging and microscopic imaging modes. A dual mode imaging system includes a sample platform movable relative to an OIS between first and second locations, and a light source subsystem configured to generate and project an illumination beam onto a focal plane. When in the first location, the sample platform coincides with the focal plane, and the OIS receives light from the sample platform along a first detection light path. When in the second location, the illumination beam interacts with relay optics and impinges on the sample platform through an objective lens, and the light from the sample platform is directed back through the objective lens and relay optics to the OIS via the first detection path.

  • Patent number: 11488322
    Abstract: This invention provides a system and method for training and performing runtime 3D pose determination of an object using a plurality of camera assemblies in a 3D vision system. The cameras are arranged at different orientations with respect to a scene, so as to acquire contemporaneous images of an object, both at training and runtime. Each of the camera assemblies includes a non-perspective lens that acquires a respective non-perspective image for use in the process. The searched object features in one of the acquired non-perspective image can be used to define the expected location of object features in the second (or subsequent) non-perspective images based upon an affine transform, which is computed based upon at least a subset of the intrinsics and extrinsics of each camera. The locations of features in the second, and subsequent, non-perspective images can be refined by searching within the expected location of those images.

  • Patent number: 11353389
    Abstract: Examples disclosed herein relate to system and method for detecting the size of a particle in a fluid. The system includes a conduit for transporting a fluid and a sample area. Some of the fluid passes through the sample area. A first imaging device has an optical lens and a digital detector. A laser source emits a first laser beam. The digital detector generates a metric of an initial intensity of a scattered light that passes through the optical lens. The scattered light is scattered from particles passing through the sample area, and includes light from the first laser beam, which passes through the sample area. A controller outputs a corrected particle intensity based upon a comparison of the initial intensity to data representative of intensity of a focused and defocused particle. The corrected particle intensity generates a corrected metric corresponding to an actual size of the particles.

  • Patent number: 10818000
    Abstract: Data indicative of a group of defect candidates may be obtained. The data may be indicative of a group of defect candidates and may include values of attributes for each defect candidate of the group of defect candidates. Sub-groups of defect candidates may be iteratively selected for review using a review recipe to classify the defect candidates in each selected sub-group based on the values of attributes of respective defect candidates and classification results of previously reviewed defect candidates. The sub-groups may be selected until a sampling stop condition is fulfilled to obtain a classification output for the wafer. Instructions specifying at least one of the sampling stop condition, the inspection recipe, or the review recipe may be altered and additional defect candidates in a next wafer may be classified by using the altered instructions.

  • Patent number: 10755133
    Abstract: A system and method for identifying line Mura defects on a display. The system is configured to generate a filtered image by preprocessing an input image of a display using at least one filter. The system then identifies line Mura candidates by converting the filtered image to a binary image, counting line components along a slope in the binary image, and marking a potential candidate location when the line components along the slope exceed a line threshold. Image patches are then generated with the candidate locations at the center of each image patch. The image patches are then classified using a machine learning classifier.

  • Patent number: 10718609
    Abstract: This disclosure relates to calibrating a volumetric estimation device for determining dimensions of an object. Two laser sources project two laser lines onto the object to form a rectangular calibration target. A camera captures an image of the rectangular calibration target and has a camera image plane and a camera image plane centre point. A processor measures the camera distortion effects to generate a filter to remove the distortion effects to approximate a pinhole camera. The camera image plane centre point and the points of projection of the laser sources are not collinear. The point of laser projection are not collinear with the camera image plane centre point. The processor uses locations of laser projected crosslines to determine a deviation angle from a direction perpendicular to the camera image plane and the distance between the camera image plane centre point and each laser source.
