Embodiment Construction

[0022] In the field of optics, FOV (Field of View) is the field of view, which refers to the maximum field of view that the lens can capture, including the diagonal field of view FOV-D, the horizontal field of view FOV-H and the vertical field of view FOV-V, its size relationship FOV-D>FOV-H>FOV-V. In order to adapt to the complete acquisition of the optical-mechanical focusing image during auto-focusing, and because the focusing circle has a high requirement for the vertical field of view, the PCB board needs to be rotated at a certain angle during assembly, which brings a certain error and assembly difficulty. Therefore, the solution provided in this embodiment can simply and quickly solve the above problems by converting the vertical viewing angle and the horizontal vertical viewing angle.

[0023] A lens assembly method, characterized in that: first determine the horizontal direction and vertical direction corresponding to the PCB board, and then determine the correspondi...

Abstract

The invention discloses a lens assembly method and system. The assembly method includes the following steps: determining the horizontal direction and the vertical direction corresponding to the PCB board, and determining according to the horizontal field of view FOV‑H and the vertical field of view FOV‑V of the lens Corresponding to the FOV-H direction and FOV-V direction, after the lens is rotated and installed on the corresponding position of the PCB board, the PCB board with the lens installed is fixed facing forward and facing the front to complete the assembly of the lens. The technical solution provided by the present invention can capture larger images in the up and down directions, ensure that the camera can capture images of the focus circle, improve the reliability of the auto-focus function, reduce the requirements for positioning accuracy, have simple design, convenient assembly, and improve efficiency. ; and the implementation cost of the technical solution is simple, easy to operate, and the assembly and assembly errors of the equipment are small, which can effectively solve the cost, improve the production efficiency, improve the automatic focus effect and optimize the user experience in actual production.

Description

technical field [0001] The invention relates to the field of automatic focusing, in particular to a focusing lens assembly method and system. Background technique [0002] With the development of projection technology, projection equipment is becoming more and more popular in the office and home fields, and the focus definition of projected images is an important factor in determining user experience. Existing projection focus adjustments mainly include two types: manual adjustment and automatic adjustment. The traditional manual focus adjustment is not only time-consuming and labor-intensive, but also the adjustment effect and clarity are not good. Autofocus is to adjust the lens position to the best position according to the calculated image definition value by obtaining the current focusing image. This type of focusing can effectively improve the user experience and is a key research direction in the projection industry. [0003] In the existing auto-focus components of...
