Problems solved by technology

There are many problems in this solution. For example, when the gimbal rotates, the focus is interrupted when the focus is not clear, which may cause the shooting picture to remain in a defocused state during the process of turning the gimbal (controlling the gimbal to track the target), and the tracking gap When turning the gimbal, triggering the focus every time the gimbal turns ends will cause the image to have an obvious focusing process, especially at night

Embodiment Construction

[0040] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0041] The tracking and focusing method for the pan-tilt camera provided by this application can be applied to such as figure 1 shown in the application environment. in, figure 1 The pan-tilt camera in comprises a rotatable pan-tilt 104 and a camera 102 installed on the pan-tilt. The camera 102 is installed on the pan-tilt 104. When the camera 102 tracks and shoots a target object, the rotation of the pan-tilt 104 drives the camera 102, so that the target Objects are always within the field of view of the camera. Wherein, the camera 102 can be, but not limited to, a bul...

Abstract

The invention relates to a tracking and focusing method and device for a holder camera, the camera and a medium. The holder camera comprises a rotatable holder and a camera installed on the holder. The method comprises the steps that the rotation state of the holder is detected, when the holder is in rotation, if focusing is completed through an automatic focusing algorithm of a camera, focusing is conducted through a preset adjustment focusing algorithm, and when the holder is in non-rotation, focusing is conducted through a preset non-edge clear focusing algorithm. By adopting the method, the focusing effect of the holder camera in the tracking process and before and after tracking can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of focusing, and in particular to a tracking and focusing method, device, camera and medium for a pan-tilt camera. Background technique [0002] Camera equipment in the security industry generally has intelligent functions such as area intrusion detection and tripwire intrusion detection. When the target object triggers a behavior rule, the built-in algorithm of the device will continuously track the object by controlling the pan / tilt and zoom motor. How to track the object during the tracking process? In order to keep the shooting picture clear to the greatest extent, it brings great challenges to the focusing algorithm. [0003] At present, the camera equipment uses a zoom follow algorithm during the zooming process, and then focuses after zooming. When the pan / tilt rotates, it interrupts and stops focusing, and refocuses when the pan / tilt ends. There are many problems in this solution. For exam...
