  • Patent number: 10949995
    Abstract: Example embodiments of the present disclosure provide a method and a server image capture direction recognition, a method and a system of surveillance, and an image capture device. The recognition method includes: extracting deep features of a target image captured by a camera; based on degree of matchings between deep features of the target image and deep features of a plurality of reference images, determining a matched reference image of the target image; obtaining a coordinate position relationship between the matched reference image and the target image; using the coordinate position relationship and direction information of the matched reference image, calculating the image capture direction of the camera at the time of capturing the target image. Example embodiments of the present disclosure may quickly and accurately recognize an image capture direction of a camera, improving processing efficiency of image capture direction recognition.
