1. An unmanned aerial vehicle (UAV) comprising:
- a camera device;
at least one processor coupled to the camera device; and
a storage device coupled to the at least one processor and stores one or more programs, the one or more programs executed by the processor, the one or more programs comprising;
creating a sample database for reflecting a plurality of features of a user;
storing the plurality of features of the user in the storage device;
receiving consecutive images of a scene from the camera device;
acquiring features of at least one object present in the consecutive images;
storing the features of the at least one object in the storage device; and
determining whether a size change of the object image is less than a relative percent value in a storage time, and sending an alarm signal to the user in response to the size change of the object image being less than the relative percent value in the storage time.

Abstract
An unmanned aerial vehicle (UAV) detecting method is executed and applied in an UAV. The method can include creating a sample features database for a user, and storing the sample features database in a storage device; shooting a plurality of scene images from every direction around the user; capturing a plurality of features of the object from the scene image; comparing the sample features of user with the features of the object, and storing a new feature of the object different from the sample feature of user in the storage device; determining whether a tagger is around the user, and sending an alarm signal to the user.

5. A detection method operated in an unmanned aerial vehicle (UAV), the UAV comprising a camera device and a storage device, the detection method comprising:
-
creating a sample features database for a user, and storing the sample features database in the storage device; shooting a plurality of scene images from every direction around the user; capturing a plurality of features of the object from the scene image; comparing the sample features of user with the features of the object, and storing a new feature of the object different from the sample feature of user in the storage device; computing whether a storage time of features of object stored in the storage device exceeding an alarm time; computing whether a size change of features of the object exceeds a preset percent value, when the storage time of features of object stored in the storage device exceeds the alarm time; and sending an alarm signal to the user in response to the size change of features of the object exceeding the preset percent value. - View Dependent Claims (6, 7, 8)
