摘要： A method is presented for processing an image of a two-dimensional (2D) matrix symbol having a plurality of data modules and a discontinuous finder pattern, each distorted by “donut effects”. A resulting processed image contains an image of the 2D matrix symbol having a continuous finder pattern suitable for conventional 2D matrix symbol locating techniques, and having a plurality of data modules, each data module having a center more truly representative of intended data, and suitable for conventional 2D matrix symbol sampling and decoding. The method includes sharpening the distorted image of the 2D matrix symbol to increase a difference between low frequency and high frequency image feature magnitudes, thereby providing a sharpened image, and smoothing the sharpened image using a moving window over the sharpened image so as to provide a smoothed image, the moving window and a module of the 2D matrix code being of substantially similar size.

摘要： A method is provided for reading distorted optical symbols using known locating and decoding methods, without requiring a separate and elaborate camera calibration procedure, without excessive computational complexity, and without compromised burst noise handling. The invention exploits a distortion-tolerant method for locating and decoding 2D code symbols to provide a correspondence between a set of points in an acquired image and a set of points in the symbol. A coordinate transformation is then constructed using the correspondence, and run-time images are corrected using the coordinate transformation. Each corrected run-time image provides a distortion-free representation of a symbol that can be read by traditional code readers that normally cannot read distorted symbols. The method can handle both optical distortion and printing distortion. The method is applicable to “portable” readers when an incident angle with the surface is maintained, the reader being disposed at any distance from the surface.

摘要： The invention provides methods and appartaus for analysis of images of two-dimensional (2D) bar codes in which a model that has proven successful in decoding of a prior 2D image of a 2D bar code is utilized to speed analysis of images of subsequent 2D bar codes. In its various aspects, the invention can be used in analyzing conventional 2D bar codes, e.g., those complying with Maxicode and DataMatrix standards, as well as stacked linear bar codes, e.g., those utilizing the Codablock symbology. Bar code readers, digital data processing apparatus and other devices according to the invention be used, by way of non-limiting example, to decode bar codes on damaged labels, as well as those screened, etched, peened or otherwise formed on manufactured articles (e.g., from semiconductors to airplane wings). In addition to making bar code reading possible under those conditions, devices utilizing such methods can speed bar code analysis in applications where multiple bar codes of like type are read in succession and/or are read under like circumstances—e.g., on the factory floor, at point-of-sale locations, in parcel deliver and so forth. Such devices can also speed and/or make possible bar code analysis where in applications where multiple bar codes read from a single article—e.g., as in the case of a multiply-encoded airplane propellor or other milled parts. The invention also provides methods and apparatus for optical character recognition and other image-based analysis paralleling the above.

摘要： An embodiment of the invention provides a method for training a system to inspect a spatially distorted pattern. A digitized image of an object, including a region of interest, is received. The region of interest is further divided in to a plurality of sub-regions. A size of each of the sub-regions is small enough such that a conventional inspecting method can reliably inspect each of the sub-regions. A search tool and an inspecting tool are trained for a respective model for each of the sub-regions. A search tree is built for determining an order for inspecting the sub-regions. A coarse alignment tool is trained for the region of interest. Another embodiment of the invention provides a method for inspecting a spatially distorted pattern. A coarse alignment tool is run to approximately locate a pattern. Search tree information and an approximate location of a root image, found by the coarse alignment tool, is used to locate sub-regions sequentially in an order according to the search tree information. Each of the sub-regions is inspected, the sub regions being small enough such that a conventional inspecting method can reliably inspect each of the sub-regions.

摘要： A method and system for probe-based pattern matching including an apparatus for synthetic training of a model of a pattern. The apparatus comprises a sensor for obtaining an image of the pattern and a processor for receiving the image of the pattern from the sensor and running a program. In the steps performed by the program a boundary of the pattern in the image is identified. A plurality of positive probes are placed at selected points along the boundary of the pattern and at least one straight segment of the boundary of the pattern is identified. The at least one straight segment of the boundary is extended to provide an imaginary straight segment and a plurality of negative probes are placed at selected points along the imaginary straight segment, where each negative probe has a negative weight.

摘要： Disclosed are methods and apparatus for automatic optoelectronic detection and inspection of objects, based on capturing digital images of a two-dimensional field of view in which an object to be detected or inspected may be located, analyzing the images, and making and reporting decisions on the status of the object. Decisions are based on evidence obtained from a plurality of images for which the object is located in the field of view, generally corresponding to a plurality of viewing perspectives. Evidence that an object is located in the field of view is used for detection, and evidence that the object satisfies appropriate inspection criteria is used for inspection. Methods and apparatus are disclosed for capturing and analyzing images at high speed so that multiple viewing perspectives can be obtained for objects in continuous motion.
