After the second fixed base is installed, the irradiation assembly is turned on, the camera assembly is connected to an external display, and the detection software is turned on. The relative position of the first fixed base is adjusted by adjusting the base, thereby ensuring the relative horizontal and vertical alignment of the microlens dot matrix and the camera display area.

[0008] Optionally, the adjusting base includes an adjusting base plate, a first adjusting plate, a second adjusting plate, a third adjusting plate, and a fourth adjusting plate along the direction close to the first fixed base.

[0009] By adopting the above technical solution, the adjustment base is structured with an adjustment base plate, a first adjustment plate, a second adjustment plate, a third adjustment plate, and a fourth adjustment plate, which can realize multi-dimensional adjustment of the position of the first fixed base, thereby enabling more precise adjustment of the position of the camera components to ensure the relative horizontal and vertical alignment of the microlens dot matrix and the camera display area, and improve the accuracy of the microlens in optical path measurement.

[0010] Optionally, the adjusting base has a rotation adjusting assembly on the top of the fourth adjusting plate. The rotation adjusting assembly includes a rotating base, a rotating seat rotatably arranged on the rotating base and used for the first fixed seat, and a rotation adjusting member for adjusting the rotation of the rotating seat. The rotating seat has a rotating boss on the side facing the rotating base, and the rotating base has a rotating groove for the rotating boss to rotate.

[0011] By adopting the above technical solution, the base is equipped with a rotation adjustment component. The rotating seat rotates on the rotating base through the cooperation of the rotating boss and the rotating groove.

[0019] By adopting the above technical solution, the driving component can slide horizontally along the length of the horizontal slide groove, and the moving end of the driving component abuts against the first abutting part of the lifting component, thereby driving the lifting component to rotate. When the lifting component rotates, it abuts against the bottom of the abutting component through the second abutting part, thereby achieving stable adjustment of the height of the first fixed seat, so as to better meet the height requirements when the microlens assembly and the camera assembly are pasted.

[0020] Optionally, the second fixing seat has an arrangement opening that communicates with the mounting ring groove and is used for arranging the outer frame.

The second positioning post has a second positioning hole that penetrates the upper and lower surfaces along the length direction, and a positioning screw is arranged in the second positioning hole.

[0023] By adopting the above technical solution, the second fixing seat and the mounting boss can be accurately positioned and securely connected by using the second positioning post, positioning screws and positioning screw holes on the mounting boss, thereby ensuring the accurate relative position of the microlens assembly and the camera assembly.

[0024] Optionally, the irradiation component is arranged on the mounting bracket, and the mounting bracket has an arrangement through hole for mounting the irradiation component, the axis of the arrangement through hole being arranged to coincide with the axis of the mounting boss.
