  • Publication number: 20210147075
    Abstract: Provided is a landing apparatus which guides an unmanned aircraft to avoid obstacles and lands the unmanned aircraft at a low-risk spot. The landing apparatus has a dangerous object position detecting device, a movement target spot calculating device, and a parachute control device. The dangerous object position detecting device detects the position of a dangerous object that is present in the vicinity of the unmanned aircraft attempting to land using a parachute. Based on the position of the dangerous object, the movement target spot calculating device calculates a movement target spot to which the unmanned aircraft should move at each instance in order to avoid colliding with the dangerous object and landing on a dangerous site. The parachute control device controls the parachute so that the unmanned aircraft moves to the movement target spot calculated by the movement target spot calculating device.

  • Publication number: 20200166620
    Abstract: [Problem] To provide a control apparatus that is capable of continuing monitoring even when an environmental change causes fluctuation in the coverage area of a sensor. [Solution] This control apparatus is provided with: a coverage area prediction means 1; and a control means 2. The coverage area prediction means 1 predicts, on the basis of the measurement result of the environment of an area in which an object is to be detected, a coverage area that is a range in which a stationary sensor for detecting objects can carry out measurement. The control means 2 determines the position where a mobile sensor for detecting objects is to be disposed, and controls the mobile sensor, on the basis of the coverage area predicted by the coverage area prediction means 1 and the probability that the object is present.
