Document Type and Number:
WIPO Patent Application WO/2019/179441
Kind Code:
A1
Abstract:
The present disclosure provides a focus tracking method and device of a smart apparatus, a smart apparatus, and a storage medium. The method comprises: detecting a face key point of a target user in an environmental image acquired by a smart apparatus, determining a face center point according to the face key point, and controlling the smart apparatus to perform focus tracking on the face center point; and if no face key point is found in the environment image, detecting a body key point of the target user in the environmental image, determining a body center point according to the body key point, and controlling the smart apparatus to perform focus tracking on the body center point. A body key point is used as a substitute in the above method to resolve the technical issue in which focus tracking cannot be maintained when no face key point has been detected, thereby preventing loss or missed detection of a focus point, and improving the success rate and accuracy of focus tracking.
