  • Patent number: 11107246
    Abstract: A method and an apparatus for capturing a target object and a video monitoring device are disclosed. The method includes: detecting target objects in a current panoramic video frame acquired by a panoramic camera; determining detail camera position information corresponding to each of the target objects, and determining a magnification corresponding to the target objects; performing block processing on the target objects to obtain at least one target block; for each target block, identifying first target objects, at edge positions, among target objects included in the target block, and determining, based on the first target objects, the detail camera position information and the magnification corresponding to the target block; for each target block, controlling the detail camera to adjust its position and magnification based on the detail camera position information and the magnification corresponding to the target block, and controlling the adjusted detail camera to capture the target block.
