Problems solved by technology

[0004] There are the following disadvantages in this face capture method: the speed of automatic focus cannot meet the real-time requirements of face capture—that is, when the camera moves in place, the automatic focus function needs to be executed, and the automatic focus will gradually converge on the current shooting picture. Keep converging until the current shooting picture is clear
Therefore, it takes a certain amount of time to ensure the clarity of the current picture, so the real-time performance of the capture cannot be guaranteed.

Abstract

The invention relates to the technical field of monitoring, in particular to a snapshot method and device and a camera. The snapshot method comprises the following steps: after a predetermined snapshot position is determined, obtaining a position angle parameter and a multiplying power parameter corresponding to the predetermined snapshot position; obtaining a snapshot focus parameter of the camera according to the position angle parameter and the multiplying power parameter; adjusting the focus of the camera according to the snapshot focus parameter; and enabling the camera to perform image snapshot at the predetermined snapshot position. According to the invention, the snapshot focus during snapshot of the camera can be directly set, the time for searching the focus position is reduced,the focusing time consumption is short, snapshot can be carried out in real time during monitoring, the focusing effect is good, and the fuzzy state of a shot picture is reduced to a certain extent.

Description

technical field [0001] The present application relates to the technical field of monitoring, and in particular to a method and device for capturing pictures, and a camera. Background technique [0002] PTZ camera is a camera that can move horizontally and vertically and zoom control in all directions in space, and can change the shooting angle and focus during monitoring. PTZ is short for Pan / Tilt / Zoom. [0003] The process of the existing PTZ camera capturing human faces in monitoring is as follows: the camera rotates and zooms to the scene area to be monitored according to the preset position to capture the human face; The current shooting picture is in focus; when the focus is clear, the face recognition function will be activated to capture the faces in the current picture. [0004] There are the following disadvantages in this face capture method: the speed of automatic focus cannot meet the real-time requirements of face capture—that is, when the camera moves in plac...
