Abstract: A method for verifying the authenticity of a security document by means of a camera-equipped cellphone comprises steps of acquiring a transmission mode image and a reflection mode image of the security document. Transmitted light through a plurality of perforations in a substrate of the security document is evaluated by means of the cellphone. Then, a relative positioning of the perforations with respect to a printed security features is determined, and the security document is considered “authentic” if the determined positions and the acquired images substantially correspond to pre-stored “templates” for the security document. The perforations are structured such that they are not visible to the naked eye of a human observer which makes it harder to counterfeit the security document.

Abstract: Irrespective of the layout, moving path, and moving range of the X-ray source and the detector, a highly precise image is acquired, in a similar manner as an X-ray CT scanner that is capable of acquiring a measured image using a rotation angle of 180 degrees or more. A measured image detected by the detector is converted into a rotationally measured image that is acquired by rotationally moving the X-ray source and the detector along concentric circular paths. Then, the rotationally measured image at every measurement angle is provided with a weight that gives intensity variation equivalent to that of the reconstructed image obtained from the rotationally measured images acquired by the measurement using the rotation angle range of 180 degrees, a reconstruction operation is performed, and a reconstructed image is obtained.

Abstract: A measurement machine includes an optical lens and a spectral confocal sensor. An electronic device adjusts a zoom ratio of the lens to be a maximum ratio, and calculates X, Y, Z coordinate differences between the lens center and the sensor center. The electronic device calibrates the X, Y coordinate differences at least twice, to obtain calibrated X, Y coordinate differences. The X, Y differences are replaced by the calibrated X, Y coordinate differences when the calibrated X, Y coordinate differences satisfy first predetermined requirements. The electronic device further calibrates the Z coordinate difference at least twice to obtain a calibrated Z coordinate difference. The Z coordinate difference is replaced by the calibrated Z coordinate difference when the calibrated Z coordinate difference satisfies second predetermined requirements.

Abstract: In disclosed examples, a satellite receiver dish (SRD) is peak aligned with a satellite in a geostationary orbit through use of guidance provided by a smartphone or tablet device fixedly attached to the SRD. A camera within the smartphone attached to the SRD can capture an image of a celestial object such as the sun. Celestial object data can be used to determine a predicted location of the sun at the time the image is captured. The predicted location of the sun can be used to determine an expected capture location of the sun within the captured image if the SRD was peak aligned with the satellite. A difference between the actual capture location of the sun and expected capture location of the sun within the capture image can be translated into at least one alignment adjustment for adjusting an azimuth position or an elevation position of the SRD.

After both of the determining steps and the setting step for each of the sets of attributes, the item associated with the current best score is identified.

Abstract: A processor generates a first road surface image from an image at a first time captured by an imaging device mounted on a moving body, and generates a second road surface image from an image at a second time after the first time. Next, the processor determines direction information depending on a direction of travel of the moving body between the first time and the second time from an amount of turn of the moving body between the first time and the second time. Then, the processor determines a relative positional relationship between the first road surface image and the second road surface image by using the amount of turn and the direction information, and determines an amount of travel of the moving body between the first time and the second time on the basis of the relative positional relationship.

Abstract: A vehicle peripheral obstacle notification system, used on a construction machine, detects a moving obstacle, gives composite display of the detected moving obstacle, and notifies a user thereof, the moving obstacle being at a location not appearing in a composite bird's-eye view obtained by onboard cameras acquiring images of the surroundings of the vehicle including an image immediately under the vehicle body. The system has a composite image formation part that extracts composite image formation areas from the surrounding images to compose a composite bird's-eye image. A moving obstacle is detected using the surrounding images and it is decided whether the detected position of the moving obstacle is inside or outside the composite image formation areas. If the detected position is determined to be outside the composite image formation areas, information about the detected position is extracted and an image thereof is output for superimposition onto the composite bird's-eye image.
