  • Publication number: 20230350432
    Abstract: When an acceleration equal to or larger than a threshold value is exerted to a vehicle, an unmanned air vehicle takeoff and landing dock unlocks an unmanned air vehicle in a direction opposite to a direction in which the acceleration is exerted. When an acceleration detector of the unmanned air vehicle detects the acceleration equal to or larger than a threshold value, a flight controller of the unmanned air vehicle controls flight of the unmanned air vehicle to cause the unmanned air vehicle to ascend. Further, the unmanned air vehicle starts imaging by an imaging unit and starts transmitting imaging data acquired.

  • Publication number: 20230007158
    Abstract: In an image processing apparatus, a first correction unit corrects imaging data acquired from an infrared imaging device, based on a first correction table, and outputs first corrected data. A second correction unit generates a second correction table for the imaging data in a state in which a shutter is closed, and outputs second corrected data based on the second correction table. A saturated region detection unit detects a saturated region in the imaging data. A shutter control unit performs closing control for the shutter, based on a result of detection of the saturated region. An abnormal pixel detection unit detects whether or not the imaging data acquired in the state in which the shutter is closed includes an abnormal pixel. A selection unit selects and outputs either the first corrected data or the second corrected data in accordance with a result of detection by the abnormal pixel detection unit.
