Title:
MOVEMENT PREDICTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/163116
Kind Code:
A1
Abstract:
One purpose of the present invention is to provide a movement prediction device that can predict the movement of a flying vehicle with a high degree of accuracy. This movement prediction device (100) comprises: a first light output device (220); a second light output device (230); a light reception device (270); and a computation device (114). The first light output device (220) outputs output light (310) having a spectrum component of a first optical comb having, as the comb interval, a first interval. The second light output device (230) outputs a reference light (340) having a spectrum component of a second optical comb having, as the comb interval, a second interval. The light reception device (270) receives composite light that is a combination of the output light (310), reflected light (320) generated as a result of the output light being reflected by rotor blades (11) of the flying vehicle (10), and the reference light (340), and measures the distance to the rotor blades (11) on the basis of the composite light. The computation device (114) calculates a rotation quantity representing the rotational speed of the rotor blades (11) on the basis of a change in the measured distance, and predicts the movement of the flying vehicle (10) on the basis of a change in the calculated rotation quantity.
