[0030] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0031] Please refer to Figures 1 to 8 The embodiment of the utility model provides an oblique photogrammetry device for performing multi-angle measurement by rotation, including a support mechanism, the support mechanism including a support frame 1, two sets of support rods 2 are slidably arranged in an opening opened at the upper end of the support frame 1, the support rods 2 are fixed by bolts, and the support rods 2 slide up and down in the support frame 1, and the use height of the support rods 2 can be adjusted.

[0032] At the same time, a screw rod 5 is threadedly connected to the lower side of the support frame 1, and a fixing seat 6 is connected to the lower end of the screw rod 5. After the support frame 1 is moved to the measurement location, the screw rod 5 is rotated to make the fixing seat 6 contact with the ground to improve the stability of the support frame 1.

[0033] Secondly, a rotating rod 3 is rotatably arranged on the upper side of the two groups of support rods 2, a mounting disk 4 is arranged on the rotating rod 3, and a positioning hole 7 is opened at the center of the mounting disk 4, the lower end of the positioning rod 10 is plugged into the positioning hole 7, a mounting plate 11 is arranged on the upper end of the positioning rod 10, a rotating rod 2 13 is rotatably arranged in the mounting plate 11, a housing 12 is fixedly connected to the rotating rod 2 13, and the mounting disk 4 is rotated by the rotating rod 1 3, so that the mounting plate 11 can be used in different upper and lower positions.

[0034] Since the positioning rod 10 is inserted into the positioning hole 7, in order to improve the stability of the positioning rod 10, a fixing sleeve 9 is symmetrically arranged on the upper side of the mounting plate 4. The symmetrical fixing sleeve 9 fixes the positioning rod 10 after being fitted. In order to strengthen the fixing effect of the fixing sleeve 9, a spring 8 is connected between the fixing sleeve 9 and the mounting plate 4. The spring 8 pushes the fixing sleeve 9, so that the fixing sleeve 9 fixes the positioning rod 10 more stably. At the same time, this fixing method makes the positioning rod 10 easier to disassemble.

[0035] In order to adjust the measuring angle, an angle adjustment mechanism is installed in the housing 12 , and a camera 18 is installed at the upper end of the angle adjustment mechanism.

[0036] Among them, the angle adjustment mechanism includes a frame 14 fixedly arranged inside the shell 12, a worm 15 is rotatably arranged on the lower side of the frame 14, a worm wheel 16 is rotatably arranged on the upper side of the frame 14, and the worm 15 is driven by a motor. When the motor drives the worm 15 to rotate forward and reverse, the worm wheel 16 engages with the worm 15. Since the two ends of the rotating shaft of the worm wheel 16 are fixedly connected to the two sides of the top plate 17, a camera 18 is rotatably arranged on the upper side of the top plate 17, so when the worm wheel 16 rotates forward and reverse, the worm wheel 16 drives the top plate 17 and the camera 18 to rotate back and forth, and the shooting angle of the camera 18 is adjusted in this way.

[0037] Furthermore, a gear 19 is connected to the lower end of the camera 18, and a gear 20 is rotatably provided on the top plate 17. The gear 20 is driven by a motor to make the gear 19 and the gear 2 20 mesh. The rotation of the gear 19 makes the camera 18 rotate autonomously to adjust the shooting direction of the camera 18. In combination with the reciprocating rotation of the housing 12 with the rotating rod 2 13, the insufficient angle adjustment of the worm wheel 16 and the worm 15 is compensated, thereby expanding the shooting area.

[0038] In summary, the working principle of the tilt photogrammetry device for multi-angle measurement by rotation in the embodiment of the utility model is as follows: when shooting, the shooting angle of the camera 18 is adjusted by utilizing the meshing of the worm 15 and the worm wheel 16. Secondly, the housing 12 is rotated by utilizing the rotation of the rotating rod 13, so that the shooting direction of the camera 18 is adjusted to a position opposite to the above-mentioned shooting direction according to the meshing of the gear 19 and the gear 2 20, so that the camera 18 can be adjusted in angle in another orientation, and the angle can be fully adjusted in cooperation with the worm wheel 16 and the worm 15.

[0039] 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 have 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.
