Embodiment Construction

[0022] In the optical field, FOV (Field of View) is the field of view, which refers to the maximum field of view that the lens can capture, including diagonal field of view FOV-D, horizontal field of view FOV-H and 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 focus image of the optical machine during automatic focusing, and because the focus ring has high requirements 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 the difficulty of assembly. Therefore, the solution provided in this embodiment can simply and quickly solve the above problems by converting the vertical field of view angle and the horizontal and vertical field of view angles.

[0023] A lens assembly method, which is characterized by first determining the horizontal and vertical directions corresponding to the PCB board, and then determining the corr...

Abstract

The invention discloses a lens assembling method and system. The assembling method comprises the following steps of determining a horizontal direction and a vertical direction corresponding to a PCB and determining a corresponding FOV-H direction and a corresponding FOV-V direction according to a horizontal field of view FOV-H and a vertical field of view FOV-V of a lens; and after the lens is rotatably mounted at a corresponding position of the PCB, forwardly fixing the PCB with the lens to face the front so as to complete the assembling of the lens. According to the lens assembling method and system, the acquired images in the up-down direction are larger in size and the camera is ensured to acquire focus ring images, so that the reliability of the automatic focusing function is improved, the requirement for the positioning precision is reduced, the design is simple, the assembling is convenient and the efficiency is improved; and the lens assembling method and system are simple in implementation cost, easy to operate and small in equipment assembling error, and are capable of effectively solving the cost, improving the production efficiency, improving the automatic focusing effect and optimizing the user experience in the practical 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 continues to be popularized in the office and home fields, and the sharpness of the projection image focus is an important factor that determines the user experience. The existing projection focus adjustment mainly includes two types: manual adjustment and automatic adjustment. The traditional manual adjustment of focus is time-consuming and labor-intensive, and the adjustment effect and sharpness are not good. Auto focus is to obtain the current focus image and adjust the lens position to the best position according to the calculated image clarity value. This type of focus can effectively improve the user experience and is a key research direction in the projection industry. [0003] In the existing automatic focusing components of projectors,...
