Description

Technical Field

[0001] This utility model relates to the field of 3D modeling and shooting technology, specifically to a shooting device for 3D modeling. Background Technology

[0002] Furthermore, 3D modeling requires capturing images of objects from multiple angles and all directions to ensure the integrity of the model reconstruction. For example, each part of the reconstructed object should be photographed from at least three different viewpoints. For objects with a certain height, images should be taken at different height levels to enhance the texture information restoration. However, the number of photographic layers should not be too many to avoid aerial triangulation failure, thus requiring the use of 3D modeling imaging equipment.

[0003] In existing technologies, the device typically places the model to be photographed on a platform and fixes it to a frame with cameras around it. The camera positions are manually adjusted as needed to complete the photographing of the model. However, in actual use, the device mounts its cameras on the frame and requires manual adjustment of each camera's shooting angle. Consequently, it is impossible to adjust the vertical shooting angles of multiple cameras simultaneously as needed during the preparation process, thus increasing the preparation time. Therefore, there is a need to improve the photographing device for 3D modeling. Utility Model Content

[0015] 1. This shooting device for 3D modeling, through its angle-adjusting lifting mechanism, starts motor one to quickly adjust the shooting height of the camera as needed.

An electric push rod 512 is fixedly connected to the front of the fixed plate 511. A connecting plate 513 is fixedly connected to the output end of the electric push rod 512.

A fixed frame 516 is fixedly connected to the back of the adjustment frame 515. A gear 517 is rotatably connected to the front and rear inner sides of the fixed frame 516. A limit strip 519 is fixedly connected to the front and rear inner sides of the lifting frame 527. A rack 518 is slidably connected to the outside of the limit strip 519.

[0031] Furthermore, the adjusting frame 515 is rotatably connected to the front of the lifting frame 527, and the fixing frame 516 is rotatably connected inside the lifting frame 527, which facilitates the rotation of the fixing frame 516.

[0032] Furthermore, gear 3 517 meshes with rack 518, and grooves are provided at corresponding positions of adjusting frame 515 and roller 514, with roller 514 movably connected in the grooves to facilitate synchronously driving gear 3 517 to rotate. Example

[0033] Based on the existing technology's requirement for rotational adjustment of the horizontal position, please refer to [link / reference]. Figure 5 Furthermore, in conjunction with Embodiment 1, it is further found that the rotating mechanism 4 includes a second motor 41, which is fixedly connected to the top of the fixed frame 2.

[0035] In actual operation, when the device is in use, the control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the power supply are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail. The control method of this utility model is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail. First, the model to be photographed is placed on the placement platform 3. According to the required shooting height and angle of the model, the set angle adjustment lifting mechanism 5 starts the motor 522. The motor 522 drives the first bevel gear 523 to rotate, and then the first bevel gear 523 drives the second bevel gear 524 to rotate. In turn, the second bevel gear 524 drives the trapezoidal screw 525 to rotate, so that the trapezoidal screw 525 rotates synchronously and drives the lifting mechanism. The lifting sleeve 526 moves, which in turn drives the lifting frame 527 to move, thereby quickly adjusting the shooting height of the camera 5110 as needed. Simultaneously, by activating the electric push rod 512, the connecting plate 513 moves, causing it to pull the roller 514. The roller 514 then drives the adjusting frame 515 to rotate around the connection point of the lifting frame 527, which in turn drives the fixed frame 516 to rotate. During the rotation of the fixed frame 516, the gear 517 rotates synchronously, thus... Gear 3 517 synchronously drives rack 518 to move, and in turn, it can synchronously drive multiple cameras 5110 to adjust their vertical angles. At the same time, during the shooting process, the set rotation mechanism 4 starts motor 2 41, which drives gear 1 42 to rotate, and gear 1 42 drives gear 2 43 to rotate. Gear 2 43 synchronously drives rotating disk 44 to rotate, and in the process of rotating disk 44, it synchronously drives camera 5110 to rotate horizontally, thereby adjusting the shooting position of camera 5110 in real time.
