  • Patent number: 10634314
    Abstract: A light source device includes a semiconductor laser that outputs laser light, a polarization rotator that rotates a polarization plane of the light, a polarization splitter that transmits and reflects the light in accordance with the polarization plane, and a fluorescent body that emits light by being excited by the laser light. The light source device controls an amount of the light that excites the fluorescent body by controlling a rotational angle of the polarization plane in the polarization rotator in a time-series fashion.

  • Publication number: 20200120247
    Abstract: Provided is an imaging device that is able to obtain a clear image in a relatively long distance in an environment of precipitation. A rainy weather camera includes: a light source that emits pulse light; a fan-shaped pulse light radiation unit that performs scanning in one direction with the pulse light emitted by the light source, spreads, in a direction perpendicular to the scanning direction, the pulse light for the scanning when the scanning is performed, and radiates the pulse light, which is in a state of being polarized in the direction perpendicular to the scanning direction, to an object; an imaging unit that receives reflection light from the object and performs exposure to a pixel; and a polarization filter that transmits light that is included in the reflection light received by the imaging unit and polarized to be parallel to the scanning direction. The imaging unit performs exposure only to a pixel which is synchronized with the scanning with the pulse light.

  • Publication number: 20200101984
    Abstract: Parking a vehicle at a location where parking is possible even when an obstacle is falsely detected. In a parking assistance device 1, an external environment recognition unit 11 recognizes road surface environment around an own vehicle on the basis of information detected by an external environment sensor 4 installed in the own vehicle. The display control unit 17 performs screen display using the HMI device 2 to present, to an occupant of the own vehicle, road surface information indicating the presence of an obstacle on the road surface around the own vehicle on the basis of the road surface environment recognized by the external environment recognition unit 11. The road surface information correction unit 16 corrects the road surface information and invalidates the obstacle. The parking route calculation unit 14 calculates a parking route for parking the own vehicle on the basis of the road surface information corrected by the road surface information correction unit 16.

  • Publication number: 20200074618
    Abstract: The image inspection apparatus includes a camera that images a workpiece placed on a stage and generates a workpiece image, and a second camera having an imaging field-of-view wider than that of the camera, which images the workpiece and generates a bird's eye view image. The apparatus detects a position of the workpiece based on the bird's eye view image, and positions the workpiece based on the position of the workpiece so that the workpiece is located in or near an imaging field-of-view of the camera, thereby imaging the workpiece with the camera to generate the workpiece image. The apparatus specifies a detailed position and an orientation of the workpiece in the workpiece image generated by the camera, and determines an inspection point of the workpiece in the workpiece image based on the detailed position and the orientation of the workpiece specified, thereby executing a predetermined inspection process.
