    摘要: An illumination head (1) for machine vision has an annular support (2) with first, second, third, and fourth illumination sections (3, 4, 5, and 6). The third section (5) has three sets of LEDs (12, 13, 14) arranged in a pattern so that each set illuminates at approximately the same angle. Each set is driven in succession so that a series of three monochrome images at the same angle are captured. These are superimposed by an image processor to provide a color image, although the camera is monochrome. More information can be obtained in such a color image and the high resolution and robustness of monochrome cameras is availed of.

    摘要: A measurement system (1) has a camera with a lens (12) and a separate sensor (10) mounted so that their planes (13,11) intersect at an object plane (3) according to the Scheimpflug principle. A reference camera(4) is normal and provides a 2D normal image which is used by an image processor (25) to determine a calibration image. This allows the image processor to determine height of the object (2). A single image capture provides an image of the full object, such as a ball grid array (BGA).

    摘要: A system has a projection lens directing on-axis light and low level LEDs directing light to blind microvias. A high resolution camera captures blind microvia images and an image processor recognizes defects according to classifications according to reflected light area and centroid position. The lens is telecentric for particularly effective image capture in blind microvias. The system also has an array of 6000 back lighting LEDs providing illumination for capture of images by a camera. These images are analyzed by the image processor to detect defects such as blocked through microvias.

    摘要: A machine vision system (1) has two laser sources (2, 3) to illuminate a solder deposit from both sides for comprehensive coverage without occlusion. The camera (4) has an FGPA (32) programmed to define a subset of the sensor array (20) as a region of interest to be processed for each laser source (2, 3). This reduces the amount of data transfer and processing required. The image line (31) is dynamically maintained in the region of interest by adjustement of camara Z position according to warp of the substrate (S).

    摘要: A solder paste inspection machine carries out the steps of automatically generating inspection data for solder paste deposits, automatically determining a squeegee direction of travel for said paste deposits. It associates the squeegee direction with the inspection data, and feeds the inspection data back to a solder paste printer with an indication of squeegee direction. The direction is determined from three-dimensional range maps, the direction of squeegee travel being in the direction of upward slope.

    摘要: A classification system or classifying images of solder joints has a two-sided classifier to which query cases are presented. It can operate in an environment without task-specific counter-concept cases (“bad examples”) because it filters a library of general counter-concept cases to provide a refined set of counter-concept cases. The filtering is performed by a one-sided classifier, which uses a base of task-specific concept cases to perform the filtration.

    摘要: A machine vision inspection system captures images of placed components and generates defect data. The defect data indicates defect components together with associated confidence scores. The confidence scores are generated according to factors such as the number of sides of a component lead at which paste has been detected (attribute factor), or measured component position (measurement factor). The confidence scores allow the placement machine to decide on how to act upon the defect data. They are also used by the inspection system to decide on which “visual watchpoint” series of component images to output for operator visual inspection.
