[0100] The multi-degree-of-freedom adjustment device 010 in this embodiment, by setting a mounting portion 100 and an adjustment base 200, based on the principle that three points can determine a plane, the three adjustment members 130 passing through the first adjustment holes 112 are inserted into any three second adjustment holes at an ideal adjustment angle, so that the angle between the mounting portion 100 and the adjustment base 200 can be adjusted; that is, the optical module 300 is adjusted along the Rx direction and the Ry direction relative to the object to be photographed, thereby achieving the adjustment of the angular relationship between the optical module 300 and the object to be photographed.

[0101] Furthermore, the multi-degree-of-freedom adjustment device 010 can adjust the mounting portion 100 on which the optical module 300 is mounted relative to the object along the X-axis direction, the Y-axis direction, and the Z-axis direction by setting the first adjustment module 410 and the second adjustment module 420, that is, the optical module 300 can be adjusted relative to the object along the X-axis direction, the Y-axis direction, and the X-axis direction. Therefore, the multi-degree-of-freedom adjustment device 010 can adjust the optical module 300 relative to the object along the X-axis direction, the Y-axis direction, the X-axis direction, and the Rx direction and the Ry direction by setting the mounting portion 100, the adjustment base 200, the first adjustment module 410, and the second adjustment module 420, thereby achieving five degrees of freedom that can be adjusted and meeting most adjustment requirements; at the same time, the spatial layout is reasonable, the volume is small, and the arrangement is reasonable.

[0102] Furthermore, the three degrees of freedom of the mechanism in the X-axis direction, Y-axis direction, and X-axis direction can be adjusted with visible scales, with an adjustment accuracy of 0.001mm. The adjustment scales in the Rx and Ry directions are not visible, and the measured leveling flatness can reach 0.02mm.

[0103] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
