[0002] Generally speaking, it takes a lot of time and effort to make or obtain a 3D model of an object, and it places high demands on the designer. Designers need to spend a lot of time and energy to master the use of professional 3D modeling software (such as Blender, AutoCAD, SolidWorks, etc.); they also need to understand geometry and design principles, and designing complex models requires artistic sense, imagination and creativity; even if they have certain skills and creativity, they still need more care and patience to fix errors in the model, adjust the size and optimize the structure when facing delicate and complex structures. Existing 3D scanning equipment requires people to scan objects manually, which is time-consuming and labor-intensive.

[0003] In this context, a "fully automatic three-dimensional scanning device" is proposed, which can better solve the pain points of existing 3D model design. Utility Model Content

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] See also Figure 1 to Figure 2 , the utility model provides a technical solution:

[0018] A fully automatic three-dimensional scanning device comprises a cabinet 1, a top cover with a flip structure is arranged on the top of the cabinet 1; a chassis 2 is arranged at the bottom of the cabinet 1, a rotating boss 3 is rotatably arranged on the bottom wall inside the cabinet 1, a first rotating motor 21 is fixedly installed inside the chassis 2, an output end of the first rotating motor 21 rotates through the cabinet 1, and the output end of the first rotating motor 21 is fixedly connected to the inside of the rotating boss 3; the side walls inside the cabinet 1 are all provided with scanning structures;

[0019] Wherein, the scanning structure includes a slide 11 arranged on the side wall of the cabinet 1, and a camera structure is slidably arranged on the slide. The camera structure can be any existing technology with a camera function. The four side walls of the cabinet 1 are all provided with scanning structures. Therefore, when the object to be measured is placed on the rotating boss 3, the camera structure can take pictures of the four sides of the object to be measured. Before the measurement, the camera structure on each side wall is numbered. When measurement is required, the rotating boss 3 is carried by the object to be measured and rotates, and the camera structure moves along the guide rail. By scheduling the motion relationship between the rotating boss 3 and the camera structure, photos of the object to be measured in all directions are obtained. At the same time, the number of the camera structure, the position of the slide 11 where the camera structure is located, and the rotating boss 3 are recorded when each photo is taken. The angle of rotation of the platform 3 and other information; at the same time, the camera structure and the first rotating motor 21 are electrically connected to the background, and the information exchange is completed by feeding back the captured data and the motor rotation to the background; according to the photos of the measured object in various directions, the number of the camera structure in each photo, the position of the slide 11, the angle of rotation of the boss and other data, the feedback is sent to the background, and the background uses the model to generate 3D model data of the measured object; multiple groups of camera structures can reduce the time of image acquisition, and assuming that the number of slides 11 is n, the rotating boss 3 can complete a group of shooting by rotating (360 / n) degrees at least; specifically, in the actual modeling process, the rotating boss 3 can be manipulated to rotate for several weeks, and photos under different conditions can be taken from multiple angles to facilitate the accuracy of modeling.

[0020] Specifically, the scanning structure includes a slide 11 arranged on the side wall of the cabinet 1, a threaded rod 4 is rotatably arranged in the slide 11, a second rotary motor 22 is arranged inside the chassis 2, the bottom of the threaded rod 4 rotates through the slide 11 and is fixedly connected to the output end of the second rotary motor 22; a threaded sleeve 5 is threadedly connected to the threaded rod 4, and a camera structure is connected to the threaded sleeve 5; the camera structure is arranged toward the rotating boss 3; the position of the slide 11 where the camera structure is located can be simply calculated by the time it takes for the second rotary motor 22 to complete the rotation and the distance the threaded sleeve 5 moves when the threaded rod 4 rotates one circle;

[0021] The bottom wall of the cabinet 1 is provided with a light strip 12, which is arranged around the rotating boss 3. The light strip 12 provides lighting for the interior of the cabinet 1. The inner surface of the cabinet 1 is made of a light-colored rough material, and the light source is diffusely reflected by the inner wall of the box to create a suitable shooting environment.

[0022] The working principle of the above-mentioned fully automatic three-dimensional scanning device is as follows:

[0023] First, open the top cover, then place the object to be tested on the rotating boss 3, and then close the top cover, and start the first rotating motor 21 and the second rotating motor 22 inside to obtain the motion relationship between the rotating boss 3 and the camera structure, and obtain photos of the object to be tested in various directions. According to the photos of the object to be tested in various directions obtained, the number of the camera structure in each photo, the position of the slide 11, the angle of rotation of the boss and other data, feedback is given to the background, and the background uses the model to generate 3D model data of the object to be tested.

[0024] Specifically, the positions of the objects in the photo can be confirmed by moving the position and angle of the camera structure used to take the photo, and then the modeling can be quickly completed using existing technology.
