Title:
無人機、特に自動操縦下でホバリング飛行を行うことができる無人機の水平速度を評価する方法
Document Type and Number:
Japanese Patent JP5854655
Kind Code:
B2
Abstract:
The method involves updating multiresolution representation of pyramid image type models of scene at different successively-decreasing resolutions. The texturing parameter representative of level of microcontrasts is obtained in picked-up scene. An approximation of the horizontal translation speed of drone (10) is obtained. A battery of predetermined criteria is applied to texturing parameter and to speed approximation. The optical-flow algorithm is switched to algorithm of corner detector type so as to estimate differential movement of scene from one image to next.
