Embodiment approach

[0155] As an implementation manner of the embodiment of the present invention, the device further includes:

[0156] a fourth determining module, configured to determine the size of each first target object in the current panoramic video frame;

[0157] The third determining module 540 is specifically used for:

[0158] Determine the corresponding field of view according to the size of the target candidate captured object;

[0159] According to the preset corresponding relationship between the magnification and the angle of view, the magnification corresponding to the angle of view is determined, and the determined magnification is used as the magnification corresponding to the target candidate capture object.

[0160] As an implementation manner of the embodiment of the present invention, the second determining module 530 includes:

[0161] The first determination submodule is used to calculate the posture score of each second target object at least according to the posture...

Abstract

The embodiment of the invention provides a target object snapshot method and device and video monitoring equipment, and the method comprises the steps: detecting a first target object in a current panoramic video frame collected by a panoramic camera, and determining the position information of each first target object in the current panoramic video frame; Determining a second target object whichis not snapshot; Candidate snapshot objects are determined, and the snapshot priority of each candidate snapshot object is determined; In the candidate snapshot objects, identifying a target candidatesnapshot object with a first snapshot priority, determining detail camera position information corresponding to the target candidate snapshot object, and determining a multiplying power correspondingto the target candidate snapshot object; And controlling the detail camera to adjust the position and the multiplying power of the detail camera, and controlling the adjusted detail camera to capturethe target candidate snapshot object. According to the embodiment of the invention, on the premise of ensuring the monitoring range, the monitoring image quality can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to a method, device and video monitoring equipment for capturing a target object. Background technique [0002] With the continuous development of video surveillance technology, video surveillance equipment has been widely used in the field of security. In a monitoring scene, the monitoring equipment is usually required to be able to monitor a wider range of scenes and capture a monitoring image with higher image quality. [0003] However, when using a panoramic camera with a large monitoring range (such as a gun machine, etc.) for monitoring, the target in the monitoring image is usually small, which leads to problems such as the inability to see the details of the target object. When using a detail camera (such as a dome camera, etc.) for monitoring, a clear target object can usually be obtained in the monitoring image, but the monitoring range is often smal...
