Title:
METHOD AND SYSTEM FOR DETERMINING POSITIONS OF WATCH FACE HANDS
Document Type and Number:
WIPO Patent Application WO/2019/184642
Kind Code:
A1
Abstract:
A method and system for determining the positions of watch face hands. The method comprises the following steps: step one, utilizing a camera of a photographing device to capture in real-time the watch face of a watch to produce a video; step two, the photographing device performs a recognition with respect to the video captured by the camera, the recognition being the recognition of images of the video; step three, the photographing device positions the images so that the images are positioned in a watch dial area; step four, the photographing device performs positioning processing with respect to watch hands of the watch dial area to obtain the hands; nd step five, the photographing device determines the angle at which the hands are offset from a preset point. By means of the described technical solution, first, the positions of the hands of the watch on the watch face can be calculated accurately and in real-time, secondly, no high requirement is placed on a processor of a mobile phone, the recognition is asynchronously processed, thus preventing apps of the mobile phone from lagging; moreover, the employment of a scheme of selectively ignoring image frames allows low-end mobile phones, even if incapable of quickly processing images, to perform smoothly.
