For example, Chinese patent CN219714375U (application date 20230524) discloses an oblique photogrammetry device, including a chassis; the chassis has a vertically movable plate and a drive assembly for moving the movable plate; the lower side of the chassis has a vertical camera and several oblique cameras, and each oblique camera is connected to a connecting rod on its upper side. The connecting rod passes through the lower wall of the chassis and is rotatably connected to the lower wall of the chassis. The upper end of the connecting rod is connected to a horizontal roller. The lower side of the movable plate has several horizontal guide rails that correspond one-to-one with the rollers. The rollers move horizontally along the inner side of their corresponding guide rails. This device can drive the oblique camera to change its tilt angle by using the vertical movement of the movable plate. The structure of the guide rails and rollers can stably support the oblique camera, avoid the oblique camera from shaking during operation, and ensure the quality of photogrammetry.

[0047] Example 4
[0048] like Figure 1-6As shown, an indoor modeling combined photogrammetry device includes a circular electric slide rail 4, a circular first photogrammetric guide rail 5 above the electric slide rail 4, a circular second photogrammetric guide rail 6 inside the first photogrammetric guide rail 5, and a circular third photogrammetric guide rail 7 inside the second photogrammetric guide rail 6.

[0050] Example 5
[0051] like Figure 1-6 As shown, while other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that a second electric slider 29 is slidably connected on the electric slide rail 4, and the second electric slider 29 is also fixed to the first photographic guide rail 5 through the bracket II 15.
[0052] By setting a second electric slider 29 to cooperate with the first electric slider 32, the first camera guide rail 5, the second camera guide rail 6, and the third camera guide rail 7 rotate more smoothly, thereby making the camera mechanism more stable.
[0053] Example 6
[0054] like Figure 1-6As shown, while other parts are the same as in Embodiment 2, the difference between this embodiment and Embodiment 2 is that: the photography mechanism includes a U-shaped slider 10, and the left and right sides of the U-shaped slider 10 are provided with grooves 30. The grooves 30 are provided with side guide rails 17. The U-shaped slider 10 and the side guide rails 17 slide together. The two side guide rails 17 are fixedly connected to the left and right sides of the outer slide rail 14 respectively. The top of the U-shaped slider 10 is fixedly connected to the 360-degree camera 8 through the bracket I9. The top of the U-shaped slider 10 is also fixed to the fill light 13 via bracket I9. The camera mechanism also includes an arc-shaped tube 11, which is fixed to the U-shaped slider 10. A first bearing 18 is installed inside the arc-shaped tube 11. The outer ring of the first bearing 18 is fixed to the inner wall of the arc-shaped tube 11, and the inner ring of the first bearing 18 is fixed to one end of the first rotating shaft 20. Two limiting discs 19 are fitted on the first rotating shaft 20 and are fixed to the first rotating shaft 20. Two connecting ropes 27 are arranged between the two limiting discs 19. One end of the two connecting ropes 27 is fixed to the left and right sides of the first rotating shaft 20, respectively. An arc-shaped rod 12 is fixed to the other end of each connecting rope 27. The arc-shaped rod 12 is slidably connected inside the arc-shaped tube 11. A spring 26 is arranged between the arc-shaped rod 12 and the first rotating shaft 20, and one end of the spring 26 is fixed to the arc-shaped rod 12. The other end of the spring 26 is fixedly connected to the inner wall of the arc-shaped tube 11; the other end of the first rotating shaft 20 passes through the arc-shaped tube 11 and extends to the outside of the arc-shaped tube 11; a first bevel gear 21 is sleeved on the other end of the first rotating shaft 20; the first bevel gear 21 is fixedly connected to the first rotating shaft 20; the first bevel gear 21 meshes with the second bevel gear 22; the second bevel gear 22 is sleeved on one end of the second rotating shaft 23; the second bevel gear 22 is fixedly connected to the second rotating shaft 23; the other end of the second rotating shaft 23 is fixedly connected to the inner ring of the second bearing 25; the outer ring of the second bearing 25 is fixedly connected to the outer wall of the arc-shaped tube 11; a gear 24 is fixedly sleeved on the second rotating shaft 23; a number of teeth 16 are fixedly provided on the top surface of the outer slide rail 14 along the length direction of the outer slide rail 14; the gear 24 meshes with the teeth 16; a conical plug 31 is fixedly provided on the end of the arc-shaped rod 12 away from the spring 26.
[0055] When in use, place the item to be photographed on the photography table 1, and then adjust the position of the 360-degree camera 8 and the fill light 13. Taking the initial position of the 360-degree camera 8 and the fill light 13 at the first photography guide rail 5 as an example, at this time the arc tube 11 is located at the notch of the first photography guide rail 5, and the arc rod 12 is inserted into the first photography guide rail 5.
[0056] If the 360-degree camera 8 is far from the object and needs to be moved closer, push the outer slide rail 14 towards the object. Since the arc rod 12 on the arc tube 11 is stuck in the first photography guide rail 5, the arc tube 11 cannot move. At this time, the outer slide rail 14 drives the gear 24 to rotate through the teeth 16. The gear 24 drives the first rotating shaft 20 to rotate through the second rotating shaft 23, the second bevel gear 22, and the first bevel gear 21 in sequence. This causes the first rotating shaft 20 to wind the connecting rope 27, which pulls the arc rod 12, causing the arc rod 12 to retract into the arc tube 11 and compress the spring 26 until the arc rod 12 is no longer inserted into the first photography guide rail 5.
[0057] At this point, since the arc rod 12 is no longer stuck in the first camera guide rail 5, the arc tube 11 can move forward. The spring 26 resets and drives the arc rod 12 to move in the opposite direction and gradually extend out of the arc tube 11. The arc rod 12 drives the first rotating shaft 20 to rotate in the opposite direction through the connecting rope 27. The first rotating shaft 20 drives the gear 24 to rotate in the opposite direction through the first bevel gear 21, the second bevel gear 22, and the second rotating shaft 23, so that the gear 24 moves along the teeth 16, thereby causing the arc tube 11, the U-shaped slider 10, the 360-degree camera 8, and the fill light 13 to move synchronously to the second camera guide rail 6.
[0058] At this point, the arc-shaped rod 12 abuts against the outer wall of the second camera guide rail 6. When the outer slide rail 14 is moved again, the arc-shaped tube 11 cannot move because the arc-shaped rod 12 is stuck against the outer wall of the second camera guide rail 6. At this time, the outer slide rail 14 drives the gear 24 to rotate via the teeth 16. The gear 24 then drives the first rotating shaft 20 to rotate via the second rotating shaft 23, the second bevel gear 22, and the first bevel gear 21. This causes the first rotating shaft 20 to wind around the connecting rope 27, which in turn pulls the arc-shaped rod 12, causing it to retract into the arc-shaped tube 11 and compress the spring 26.
[0059] At this point, the arc rod 12 is no longer stuck on the outer wall of the second camera guide rail 6, and the arc tube 11 can continue to move forward into the notch 3 of the second camera guide rail 6. At this point, the spring 26 resets and drives the arc rod 12 to move in the opposite direction and gradually extend out of the arc tube 11 and insert into the second camera guide rail 6, so that the arc tube 11 is fixed at the notch 3 of the second camera guide rail 6, thereby fixing the 360-degree camera 8 and the fill light 13 on the second camera guide rail 6, so that they can get closer to the items on the camera platform 1.
[0060] The first electric slider 32 drives the 360-degree camera 8 and the fill light 13 to rotate around the object via the outer slide rail 14, the U-shaped slider 10, and the bracket I 9.
