Document Type and Number:
WIPO Patent Application WO/2023/214445
Kind Code:
A1
Abstract:
A position estimation device (10) comprises an image acquisition unit (110) and a position estimation unit (120). The image acquisition unit (110) acquires a plurality of images generated by an image capture device that captures images of a space of interest in which a flying object is flying. The position estimation unit (120) estimates the position of the flying object by processing the plurality of images. The position estimation unit (120) tentatively sets the type of the flying object and estimates the distance to and the speed of the flying object. The position estimation unit (120) then updates the type of the flying object using this speed and the rate of change in the area of the flying object in the images. The position estimation unit (120) repeats the processes described above.
