  • Patent number: 10636157
    Abstract: Method and system for calculating a height map of a surface of an object from an image stack in scanning optical 2.5D profiling of the surface by an optical system, a focal plane is scanned at different height positions with respect to the object surface. An image is captured at each height position of the focal plane to form the image stack. The scanning of the focal plane comprises long range sensing and short range sensing a displacement of the focal plane for sensing low and high spatial frequency components. The height position of the focal plane is estimated by combining the low and high spatial frequency components. A height position of each image in the image stack is calculated, based on the estimated height position of each respective focal plane. The images of the image stack are interpolated to equidistant height positions for obtaining a corrected image stack.

  • Patent number: 9547924
    Abstract: Software is provided for functioning in conjunction with a plurality of mission stores and for assisting a pilot of a vehicle with release of the mission stores to achieve a specified number of mission objectives. Each of the plurality of mission stores may be designated for communication with a separate mission reference point or target. The targets may be grouped within a common target area. The software provides processor-executable instructions for determining acceptable timing and location for release of the plurality of mission stores, such as within the common target area, and such that the mission stores achieve communication with the respective mission reference points. The processor-executable instructions calculate and identify a common release area within the common target area, such as a composite launch acceptability region of overlap of separate target regions of each mission store, in addition to identifying an entrance and exit point of the composite region.

  • Patent number: 9489555
    Abstract: A method and system for reading code symbols using a code symbol reading system having a programmable decode time-window filter mode of operation. During this mode of operation, only decoded code symbols that have been scanned within a selected (e.g. central) portion of the laser scan line field are processed according to a special decode time-window filtering function. In particular, if the decoded bar code symbol is a programming-type bar code symbol, then the system controller applies the function represented by the programming-type bar code symbol; and if the decoded bar code symbol is a non-programming-type bar code symbol, then the system controller either transmits symbol character data associated therewith to the host system or stores the symbol character data within memory aboard the bar code symbol reading system.

  • Patent number: 9361504
    Abstract: To prevent misreading of barcodes and to allow accurate outputting of bar data even when an element is damaged or blurred, an optical information reading device containing a computation means 23a for adding widths of 6 elements containing a bar and a space that are adjacent within one character to derive respective patterns of 2- through n-element added widths and for converting each of the patterns of 2- through n-element added widths into the module number for one character to obtain the module numbers of the patterns of the 2- through n-element added widths; an extraction means 23b for narrowing down the target characters to extract a candidate character wherein the target character is that each module number of the 2- through n-element widths is an integer with an error equal to or less than 1; and a search means 23d for comparing the extracted candidate character, having the module numbers of the patterns of the 2- through n-element added widths with the expected value character for evaluating the candid

  • Patent number: 9275264
    Abstract: In a system and method of estimating and classifying a barcode using heuristic and statistical measures, a classification determination is generated for each of a plurality of estimated barcode digits that correspond to a decoded barcode estimation. The classification determination is selected from one of a first classification determination and a second classification determination. The first classification determinations among a plurality of estimation determinations are aggregated. The aggregated first classification determinations are compared to a first predetermined threshold to determine a validity of the decoded barcode estimation.

  • Patent number: 9213875
    Abstract: This invention overcomes the disadvantages of the prior art by providing a system and method for reading symbology, and more typically linear barcodes (“symbols”) that employs trained attributes that remain invariant between scans of different barcodes during runtime to tune various aspects of the procedure for locating and decoding such barcodes. The procedure relies upon a training step in which one or more exemplary barcodes are decoded and the invariant attributes for such barcodes, including, but not limited to, size, shape, relative angle in the image field of view and resolution are stored. The runtime decoding procedure then employs these attributes to constrain the search for subsequent, scanned barcodes and then decode it according to a plurality of tuned steps.

  • Patent number: 9117131
    Abstract: In a system and method of recognizing a barcode from a stream of video frames, a processor-implemented camera module receives a stream of video frames, with at least one video frame including a barcode. A processor-implemented barcode blur estimate module estimates an amount of defocus blur in a video frame. The processor-implemented barcode blur estimate module further estimates an identity of the barcode. A processor-implemented barcode localization module identifies a region of the video frame containing the barcode. A processor-implemented barcode geometric modeler module generates a geometric model of the barcode that includes an identified barcode deformity. A processor-implemented barcode decoder module decodes the barcode from the video frame using the estimated amount of defocus blur, the estimated identity of the barcode, and the geometric model of the barcode.
