Abstract

The invention is applicable to the field of video monitoring, and provides a focusing method. The method comprises the following steps: after a focusing motor moves, obtaining the definition corresponding to the current position; determining change information of the definition according to the definition, wherein the change information comprises a target change rate and / or a continuous change frequency; if the preset termination condition is not met, determining the moving direction and the moving step length of the next time of movement according to the change information, and controlling the focusing motor to execute the next time of movement according to the moving direction and the moving step length; if the preset termination condition is met, taking the position with the maximum definition as the focusing position. According to the scheme, the moving direction and the moving step length of the next moving can be determined according to the target change rate and / or the continuous change frequency, the position with the highest definition can be found more quickly, the moving frequency is reduced, and therefore the focusing efficiency is improved.

Description

technical field [0001] The present application belongs to the field of video monitoring, and in particular relates to a focusing method, equipment and computer-readable storage medium. Background technique [0002] When the front camera is auto-focusing, it needs to find the position with the highest definition. The existing method of searching for the position with the highest degree of clarity is generally to continuously acquire multiple frames of image data, determine the change trend based on the clarity of the continuous multiple frames, and determine the search direction and search step size of the next step of the focus motor according to the change trend. This determines the position with the highest clarity. [0003] However, in this way, due to disturbances such as noise, there may be jitters, and the sharpness of consecutive multiple frames does not necessarily show a monotonous rise or fall trend, and the resulting change trend is prone to misjudgment. When , ...
