Abstract
A method for determining an external state of an unmanned aerial vehicle (UAV) includes obtaining historical external state information of the UAV, obtaining a current image and a historical image captured before the current image, predicting a matching feature point in the current image that corresponds to a target feature point in the historical image according the historical external state information, and determining the external state of the UAV based on the matching feature point.
Claims20
A method for determining an external state of an unmanned aerial vehicle (UAV) comprising:
- obtaining historical external state information of the UAV;
- obtaining a current image and a historical image captured before the current image;
- predicting, according the historical external state information, a matching feature point in the current image that corresponds to a target feature point in the historical image;
- and
- determining the external state of the UAV based on the matching feature point.
A system for controlling an unmanned aerial vehicle comprising:
- a processor;
- and
- a memory storing program instructions that, when executed by the processor, cause the processor to:
- obtain historical external state information of the UAV;
- obtain a current image and a historical image captured before the current image;
- predict, according the historical external state information, a matching feature point in the current image that corresponds to a target feature point in the historical image;
- and
- determine the external state of the UAV based on the matching feature point.
