Embodiments of the present application provide a method and apparatus for determining a trajectory of a human target. The method includes: extracting a target feature of a to-be-tracked human target in a to-be-processed image as a to-be-searched target feature; searching for an acquisition attribute corresponding to the to-be-searched target feature based on a pre-established correspondence between target features and acquisition attributes; determining a trajectory of the to-be-tracked human target based on the found acquisition attribute. It can be seen that in this solution, a face image is not required for determining a trajectory of a person. Even if the acquired face image is not clear, the accuracy of determining the trajectory of the person will not be reduced. Therefore, by the solution of the present application, the accuracy of determining the trajectory of the person is improved.

Method and device for determining path of human target

The embodiments of the present application provide a method and apparatus for recognizing an identity of a human target. The method includes: obtaining a to-be-recognized image; extracting a target feature of a to-be-recognized human target in the to-be-recognized image as a to-be-searched target feature; searching for a facial information item corresponding to the to-be-searched target feature based on a pre-established correspondence between target features and facial information items; and determining an identity of the to-be-recognized human target based on the found facial information item. It can be seen that, in this solution, there is no need to extract the facial features in the image, and even if the facial region is not clear or is shaded by other objects in the image, the accuracy of identity recognition is reduced. Therefore, accuracy of identity recognition is improved.

Method and device for recognizing identity of human target

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.

Method and device for capturing target object and video monitoring device

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.
