Abstract

The invention relates to a movement lens operation state control method and device and a computer device. The movement lens operation state control method comprises the following steps of: obtainingan evaluation parameter of a movement lens; setting a first control parameter of the movement lens according to the evaluation parameter; controlling the movement lens to operate according to the first control parameter; acquiring an operation parameters of the movement lens; according to the operation parameter and the evaluation parameter, correcting the first control parameter to obtain a second control parameter; and controlling the movement lens to operate according to the second control parameter. The control method solves the problem that the movement lens is easy to desynchronize due to a high-rotation-speed control group in related technologies, controls the movement lens to have different operation speeds in different operation periods of the movement lens, reduces the probability of desynchrony of the movement lens, and prolongs the service life of the movement lens.

Description

technical field [0001] The present application relates to the technical field of video surveillance, in particular to a control method, device and computer device for the operating state of a movement lens. Background technique [0002] With the improvement of living standards, the user's demand for security continues to increase, and security monitoring technology continues to develop. The focal length, faster speed, higher precision, longer life and so on. Among them, the movement lens is also called all-in-one movement or integrated movement. It is a key component of the front-end fast dome. It is mainly used for zoom imaging and directly affects the imaging quality of the entire camera. The movement lens mainly drives each Each group in the lens performs optical zoom or auto focus. [0003] In the related technology, the control structure of the movement lens itself includes a high-speed control group and a low-speed control group. The high-speed control group makes th...
