Embodiments of the present application provide a method, apparatus and video monitoring device for capturing a target object. The method comprises detecting target objects in current panoramic video frame acquired by panoramic camera, and determining first position information, size, moving direction, and speed information of each target object in the current panoramic video frame; calculating position information for capturing of each target object; determining detail camera position information corresponding to each target object and determining a magnification corresponding to each target object according to size thereof; and determining a tracking duration for each target object, and controlling, for each target object, the detail camera to adjust its position and magnification according to the detail camera position information and magnification corresponding to the target object, and controlling the adjusted detail camera to capture the target object within the tracking duration for the target object. Embodiments of the present application can improve the quality of capturing of a target object while ensuring the monitoring range.
