Example Embodiment

[0026] Example 1

[0027] Refer to image 3 Shown is a flowchart of a method for adjusting a shooting focus provided by an embodiment of the present invention. The shooting control method is executed in the foregoing figure 1 , figure 2 On the server or / and camera device in, specifically include:

[0028] The first position information of at least one moving object is determined (step S310).

[0029] Specifically, taking the moving object as a racing pigeon as an example, the smart foot ring of each racing pigeon includes a positioning device. The positioning device can obtain the current geographic position of the racing pigeon and generate first position information. The latitude and longitude means the geographic location of the pigeon. For example, in an application scenario where the moving object is an indoor activity of an intelligent robot, each intelligent robot is provided with a positioning device for obtaining indoor geographic location information of the intelligent ro...

Example Embodiment

[0050] Example 3

[0051] Refer to Figure 5 As shown, it is a block diagram of a photographing focus adjustment device module provided by an embodiment of the present invention. The photographing focus adjustment device 500 may run on a server or a photographing device, which includes:

[0052] The object position determination module 510 is configured to determine first position information of at least one moving object.

[0053] The distance calculation module 520 is configured to determine the distance value between the camera and the at least one moving object according to the second position information of the camera and the first position information of the at least one moving object.

[0054] The focal length calculation module 530 is used to calculate the focal length value of the photographing device according to the distance value.

[0055] Further, in the embodiment of the present invention, the focal length calculation module 530 is specifically configured to determine the...

Abstract

The invention discloses a photographing focal length regulating method. The method comprises steps of: determining first position information of at least one motion object; according to second position information of a photographing device and the first position information of the at least one motion object, determining a distance between the photographing device and the at least one motion object; and calculating a focal length of the photographing device according to the distance, wherein the focal length is used for regulating a focal length of the photographing device. In the method, position information of the motion object is acquired, the focal length of the photographing device is determined through the position information of the motion object and position information of each photographing device, the focal length of the photographing device is determined accurately and automatically, and better photographing effect is achieved. The invention further discloses a photographingfocal length regulating device, a server and a storage medium.

Description

technical field [0001] The invention belongs to the field of image acquisition, and in particular relates to a shooting focus adjustment method, device, server and storage medium of a shooting device. Background technique [0002] When people shoot an object, in order to obtain a better quality image, it is necessary to adjust the focal length of the photographing device to obtain a better focal length value, so as to obtain an image with higher image quality. [0003] The inventor's long-term research has found that the present mode of adjusting the focal length includes both manual and active modes. In the way of automatically adjusting the focus, the distance of the target object is generally captured by infrared rays. However, this method has disadvantages in some scenarios. For example, when the shooting target object is relatively small, it is difficult for infrared rays to irradiate the shooting target object; or because the shooting target object is relatively far a...
