Title:
METHOD AND SYSTEM FOR ELECTRONIC IMAGE STABILIZATION, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/176963
Kind Code:
A1
Abstract:
Disclosed are a method and system for electronic image stabilization, and an unmanned aerial vehicle. The method comprises: acquiring an image stabilization region; determining, from a pre-established virtual camera coordinate system, a region corresponding to the image stabilization region so as to obtain a first region, wherein the virtual camera coordinate system is a coordinate system established in a virtual camera in a stationary position with respect to a world coordinate system; determining, from a physical camera coordinate system, a region corresponding to the first region so as to obtain a second region; determining, from an image coordinate system, a region corresponding to the second region so as to obtain a third region; and performing, according to a mapping relationship between the image stabilization region and the third region, a mapping operation to map, to the image stabilization region, an image to be stabilized captured by a physical camera on an unmanned aerial vehicle so as to obtain a stabilized image. The present invention realizes execution of image stabilization processing on an image captured by an unmanned aerial vehicle.
