Abstract
Achieved is a configuration in which a reliability of self-position estimation of a mobile device, such as a drone, is calculated to perform warning display and flight control. A sensor data acquisition unit that acquires detection information of a sensor provided in a mobile body, a self-position estimation unit that receives an input of the detection information of the sensor from the sensor data acquisition unit and executes self-position estimation of the mobile body, an environment information analysis unit that analyzes environment information such as ambient brightness when a self-position estimation process has been executed in the self-position estimation unit and a score of a feature point of a camera-captured image, and an estimated self-position reliability calculation unit that calculates a reliability of a self-position estimated by the self-position estimation unit on the basis of the environment information analyzed by the environment information analysis unit are provided to perform warning display and flight control on the basis of the calculated reliability.
