  • Publication number: 20180336691
    Abstract: Whether to correct unevenness of brightness of a first image of an object onto which pattern light for three-dimensional shape measurement is projected is determined based on the first image or a second image of the object onto which the pattern light is not projected. If correction is performed, the three-dimensional shape of the object is measured using a corrected image obtained by correcting the unevenness of the brightness of the first image based on the second image; otherwise, the three-dimensional shape of the object is measured using the first image.

  • Publication number: 20180275017
    Abstract: An electronic control unit of a misfire detection device is configured to calculate first time series data based on a detected angle signal of a rotating shaft and a crank signal of a crankshaft in a connected state, a state where the rotating shaft and the crankshaft are connected. The electronic control unit is configured to generate, in the connected state, second time series data acquired by removing a predetermined frequency component from time series data indicating a rotational behavior of the crankshaft. The electronic control unit is configured to generate third time series data indicating the rotational behavior of the crankshaft by combining the second time series data with the predetermined frequency component based on the first time series data and the second time series data. The electronic control unit is configured to determine presence of misfire in an internal combustion engine based on the third time series data.

  • Patent number: 10068056
    Abstract: This invention provides a mechanism for making a doctor surely follow correct procedures in which the doctor confirms diagnosis information obtained by computer processing after he or she has completed interpretation. A medical diagnosis support apparatus executes diagnosis processing for acquiring medical diagnosis information from an image to be interpreted by computer processing. The medical diagnosis support apparatus accepts interpretation information as an interpretation result of the image to be interpreted, which information is input by, for example, a doctor. The medical diagnosis support apparatus calculates a degree of matching between the diagnosis information and interpretation information, and permits to present the diagnosis information acquired by the diagnosis processing when the calculated degree of matching exceeds a predetermined threshold.
