摘要： An apparatus is provided for forming an image of the periphery of an object with a camera having optics disposed at a working distance that is significantly less than the focal length of the optics, without introducing image distortion. The invention provides an image formation apparatus having a reduced effective profile height by exploiting a folded optical path to provide reduced working distance between a camera and an object of interest, such as a semiconductor wafer, as compared with direct viewing of the object. In a preferred embodiment, the invention includes two reflecting substrates, a first reflecting substrate and a second reflecting substrate. The distance between the first and second reflecting substrates determines the number of times the light rays that form the image will bounce therebetween, and consequently, the number of images of an object periphery that will appear in the field of view (FOV) of the camera. The invention provides an image formation system that can operate within the small or narrow enclosures of some existing wafer fabrication equipment. The invention also provides reduced camera vibration.

摘要： An apparatus and method are provided for automatic visual inspection of crescent-shaped wire bonds. The apparatus includes image acquisition means for acquiring an image of a wire and an image of a crescent-shaped wire bond. A search model is used that includes a crescent-modeling portion, and can also advantageously include a wire modeling portion. Search functionality is used to find an image of the crescent-shaped wire bond, using the search model, so as to provide location information regarding the location of the crescent base, and shape-match information regarding the reliability of the found location information. The invention is useful for verifying the correct position of the crescent bond to ensure good electrical contact. In addition, the invention greatly simplifies the task of two other important automated visual inspection steps: wire location and crescent shape determination. Presence/absence of the crescent bond can also be determined using this information.

摘要： A method and system detect for the presence of a defect or a non-conforming object of unknown shape, configuration, and location within a semi-opaque enclosure. The semi-opaque enclosure has a pattern which is visible on at least a first of its external surfaces. The semi-opaque enclosure may comprise, for example, a labeled plastic or glass bottle, and the visible pattern may be print and graphical information provided on the bottle's label. A first digital image is captured from first channel light reflected off the first external surface of the enclosure; and a second digital image is captured from second channel light navigating the object inside the enclosure and emanating from the first external surface of the enclosure. A difference image is formed substantially devoid of information representing the visible pattern on the first external surface, by subtracting one of the first and second digital images from the other. Additional segmentation processing may be performed on the difference image in order to better identify the presence of a defect or non-conforming object within the semi-opaque enclosure.

摘要： The invention provides machine vision methods and apparatus for determining a calibration relationship between the imaging reference frame of an image acquisition device (e.g., a camera) and the motion reference frame of a moveable object (e.g., a motion stage) by positioning the object so that a fiducial thereon (e.g., a calibration mark) lies at a first fiducial position in the field of view and recording the corresponding position of the object in the motion reference frame. The object is then repositioned so that the fiducial moves to a second fiducial position in the field of view. Again, the corresponding position of the object in the motion reference frame is recorded. Likewise, the object is moved to a third fiducial position in the field of view, and its corresponding position in the motion reference frame is recorded. A calibration relationship between the motion reference frame of the object and the imaging reference frame of the camera as a function of the first, second and third fiducial positions and as a function of the first, second and third object positions.

摘要： Machine vision methods for determining a characteristic (such as position, orientation, size, center of mass, and boundary) of an object in an image include finding points in the image on the boundary of the object; identifying bounding boxes, or regions, in the image that correspond to edges of the object; and labeling boundary points to denote which respective edges, if any, to which they belong based on (i) the locations and orientations of those points, and (ii) locations of the plural bounding boxes. Points apparently lying on a boundary of the object, but outside a bounding box, can be ignored--and, more particularly, are denoted as not corresponding to an edge. Likewise, apparent boundary points lying within a bounding box, but at an angle not associated with the corresponding to the respective edge of the object, can also be ignored. Characteristics of the imaged object are determined as a function of those boundary points found to correspond to an edge of the object (e.g., points lying within a bounding box, at the expected angle, and not too far from a line connecting similarly situated points). Characteristics of the object, such as position, orientation, size, center of mass, and boundary points, can be determined in the image reference frame.

摘要： The invention automatically inspects the bond of a wire to a contact pad on a semiconductor chip. The apparatus includes a movable platform for holding semiconductor chips situated in lead frames; a video camera for sensing images; illumination means for illuminating a chip in a lead frame; an image processor to digitize and analyze the images; a bonding mechanism; and a host controller electronically connected to bonding mechanism, movable platform, video camera, and image processor. Image processor locates a bond on a pad in a digitized image and provides a first nominal center of ball bond image. The invention aligns the center of a polar coordinate transform image having one or more segments with the nominal center of ball bond image and evaluates ball bond image using the polar coordinate transform image to create a polar projection histogram array and store it. An edge filter is applied to histogram array to detect peaks and store their number and values. Polar coordinate transform image is aligned with a next nominal ball center location until a predetermined number of potential ball center locations is exhausted. The maximum peak in the list of stored peaks is selected as the radius of bond from which the size and position of bond is computed and reported to host controller for further action.

摘要： A method for Golden Template Comparison (GTC) is provided that can be used to efficiently perform flaw and defect detection on a two-dimensional test image that is at least rotated and/or scaled and/or sub-pixel translated. Run-time inspection speed and accuracy is substantially improved by retreiving a golden template image that is rotated and/or scaled and/or translated in a manner substantially similar to the test image. This is accomplished by storing, in an array, a varied plurality of golden template images, each golden template image being characterized by a different combination of at least rotation and/or scale and/or sub-pixel translation. The array is indexed by the respective quantized rotation and/or quantized scale and/or sub-pixel translation of each version of the golden template image. The array can be either one-dimensional or multi-dimensional. At run-time, the values of the rotation and/or scale and/or sub-pixel translation of each test image are measured, and then quantized, thereby providing a unique index into the multi-dimensional array of reference and threshold images. The reference and threshold images stored at the memory location corresponding to the index are retrieved and then used for comparison with the test image to provide a difference image to be analyzed for flaws or defects.

摘要： A coprocessor in an image processing system is coupled to the bus to which a CPU and RAM holding image data are also coupled. The coprocessor extracts an input pixel stream corresponding to input images from selected bus transactions, performs computations on the input stream to produce output pixel streams corresponding to output images, and inserts the output pixel streams into selected CPU-to-memory bus transactions so that the memory stores the data. The CPU generates the selected bus transactions with specially marked address and/or control signals. The coprocessor includes a lookup table, and a first row delay. The row delay accumulates the three most recent rows of input pixels, which are sent to Sobel and rank processing sections for neighborhood processing. The results are thresholded and formatted, and are either output directly or passed through an additional pair of row delays to accumulate three rows of result data for neighborhood peak detection.

摘要： A system for interactively generating a computer program for machine vision analysis insures that the program is correct by permitting the operator to make only syntactically correct modifications to the program. The system includes an element for storing the computer program being generated. A further element displays the program to the operator. A positioning element demarks a location of interest within the program. A menu element displays permissible programming modifications for the location of interest. The menu element incorporates in its display of permissible programming modifications statements for machine vision analysis of an object image, e.g., calls to machine vision subroutines and functions. To facilitate specification of input parameters to those subroutines and functions, the imaging element can generate a candidate image of the object upon which the machine vision analysis is to be run. A graphical input element displays over that candidate image a graphical icon that the operator can manipulate to specify the parameters. A textual input element can display an icon, e.g., a dialog box, prompting the operator to designate textually input parameters for the machine vision tool. An update element responds to the operator selection by appropriately modifying the stored program.
