Title:
IMAGING FOCUSING SYSTEM FOR SPECIFIED MONITORING AREA
Document Type and Number:
WIPO Patent Application WO/2023/103207
Kind Code:
A1
Abstract:
Disclosed in the present invention is an imaging focusing system for a specified monitoring area. The imaging focusing system comprises a focusing ring driving wheel, a lens focus-fixing ring, an electric motor system and a fixed support, wherein the electric motor system comprises an electric motor control system and an electric motor; the electric motor control system controls the rotation direction and the rotation time of the electric motor, a transmission structure in the electric motor then drives the focusing ring driving wheel to rotate, and the focusing ring driving wheel is connected to the lens focus-fixing ring, so as to control the lens focus-fixing ring to implement a focusing operation of a lens. In the present invention, the rotation of a focus-fixing ring is controlled by using an electric mechanism, without needing to perform manual focusing when a camera is mounted, and adjustment can also be performed in a timely manner after a specified area is modified. The definition of a focused image is calculated by using an assessment algorithm, and therefore, compared with a traditional subjective assessment method, focusing is more accurate. A focusing ring driver uses a gear set structure, and therefore, compared with other transmission methods, a control angle is more accurate, and thus there is no need to rotate a lens backwards.
