    摘要: A camera-parameter-set calculation apparatus includes a three-dimensional point group calculator that calculates a plurality of three-dimensional coordinates, based on first and second images respectively captured by first and second cameras and first and second camera parameter sets of the first and second cameras; an evaluation value calculator that determines a plurality of pixel coordinates in the second image, based on the plurality of three-dimensional coordinates and the second camera parameter set, determines a plurality of third pixel coordinates in a third image captured by a third camera, based on the plurality of three-dimensional coordinates and a third camera parameter set of the third camera, and calculates an evaluation value, based on pixel values at the plurality of second and third pixel coordinates in the second and third images; and a camera-parameter-set determiner that determines a fourth camera parameter set for the third camera, based on the evaluation value.

    摘要: A detection system including an autonomous collection device that is capable of moving on a floor surface and for collecting an object on the floor surface, and a station device for detecting an analyte from the object collected from the floor surface by the autonomous collection device. The autonomous collection device includes a moving part for moving on the floor surface, a primary electric blower for sucking the object on the floor surface, and a dust container for storing the sucked object. The station device includes a transfer pipe fluidically connected to the dust container of the autonomous collection device when the autonomous collection device is positioned in a home position, and a virus detection part for detecting the analyte from the object transferred from the dust container through the transfer pipe.
