  • Patent number: 10249030
    Abstract: Obtaining a good image is important for reading indicia. Often, however, objects are not well aligned with an indicia reader's digital imager. This misalignment may lead to images in which an indicium may appear distorted due to perspective. This perspective distortion makes indicia reading difficult. In general, perspective distortion of an imaged object may be corrected using knowledge of the true size, shape, and/or orientation of the physical object. The present invention embraces the use of a dimensioning system to obtain the 3D information necessary to provide this knowledge. Then, using this knowledge, to transform a distorted image of an indicium into a corrected image of the indicium without distortion. This corrected image may then be processed to read the undistorted indicium.

  • Patent number: 10229506
    Abstract: An optical tracking system comprises a marker part, an image forming part, and a processing part. The marker part includes a pattern having particular information and a first lens which is spaced apart from the pattern and has a first focal length. The image forming part includes a second lens having a second focal length and an image forming unit which is spaced apart from the second lens and forms an image of the pattern by the first lens and the second lens. The processing part determines the posture of the marker part from a coordinate conversion formula between a coordinate on the pattern surface of the pattern and a pixel coordinate on the image of the pattern, and tracks the marker part by using the determined posture of the marker part. Therefore, the present invention can accurately track a marker part by a simpler and easier method.

  • Patent number: 10210426
    Abstract: The invention relates to a method for determining an unknown position, i.e. height and/or orientation, of a light source within a locality. The determination is based on a first image of a scene within the locality acquired by a camera in such a manner as to contain a light footprint of light emitted by the light source from the unknown position. The method includes steps of processing the first image to determine one or more characteristics of the at least the portion of the light footprint within the first image, comparing the determined characteristics with one or more corresponding known characteristics of a light footprint of light emitted by the light source from a known position to determine a deviation between the determined and the known characteristics, and determining the unknown position of the light source based on the determined deviation.

  • Patent number: 10127461
    Abstract: First and second image data is captured comprising a first and second image, respectively. A fixed light source is identified in each of the first and second images. A first ground plane is determined in the first image data. A first (second) intersection is determined, wherein the first (second) intersection is a point in the first image where a virtual lamp post corresponding to the fixed light source in the first (second) image intersects with the first (second) ground plane. The first image data and the second image data are transformed to provide a first and second inverse perspective map (IPM) comprising a first transformed intersection and a second transformed intersection, respectively. Movement parameters are determined based on the location of the first transformed intersection in the first IPM and the location of the second transformed intersection in the second IPM.

  • Patent number: 7437014
    Abstract: Methods and systems for model reduction and system identification of dynamic systems with multiple inputs are disclosed. In one embodiment, a method includes generating a plurality of statistically independent random ntunbers for use as input signals, and performing a singular-value-decomposition directly on the system response due to a simultaneous excitation of the plurality of input signals. Alternate embodiments further includes sampling individual pulse responses for the first two time steps, and constructing Hankel-like matrices from which the state-space system matrices (A, B, C, D) are obtained. Since the system response is sampled almost exclusively for the single representative input, the model construction time is significantly reduced, especially for a large-scaled dynamic systems. The plurality of input signals may be filtered tbrough a low-pass filter.

  • Patent number: 7426313
    Abstract: A method and an apparatus of reducing the mosquito noise in a decoded image by using a noise reduction algorism that does not depend on the compression coding algorism applied to the image to be improved. The decoded compression-coded digital image is divided into blocks. The standard deviation or the “variance coefficient” of luminance values is calculated for each block of the decoded compression-coded digital image. An ? matrix for the compression-coded digital image is composed so that all components of each block of the ? matrix is filled with the standard deviations or the variance coefficients for each block. An ? filter is composed so that its ? values are expressed by the ? matrix. The decoded compression-coded digital image is applied to the ? filter to reduce the mosquito noise that arises during decoding process.

  • Patent number: 7421149
    Abstract: A system and associated methodology of detecting objects using multiple sets of object probability data relating to different respective expected object sizes relative to the image size. A list of locations in an image where an object has been detected is stored, the list defining a probability data set and a probability value for each detected object. Object locations in a set of object probability data as locations at which a local maximum probability value exceeds a threshold probability value are detected and, if that location is substantially similar to a location previously stored in the list, where the local maximum probability value exceeds that relating to the previously stored location. The storing is repeated successively in respect of each set of probability data.
