A 3D scanning device based on Internet of Things control

Abstract

The invention relates to a 3D scanning device based on Internet of Things control. The3D scanning device comprises a platform, a support mechanism, a turntable and a scanner. The turntable is providedwith a plurality of notches. A translation mechanism and a lifting mechanism are arranged in the notch. The translation mechanism comprises a belt and two translation assemblies each including a second drive motor, a buffer block, a second drive shaft, and a drive gear. The support mechanism includes a plurality of support units including an air pump, a cylinder, a piston, a connecting rod, a support leg, and a hinge unit. According to the 3D scanning device based on Internet of Things control, the angle of the support leg is changed by the support units so that the angle of the platform is adjusted. Thus, the platform and the turntable are in a horizontal position so as to place objects on the turntable smoothly. Moreover, the lifting mechanism is moved by the translation mechanism in the notch, an object is fixed by enabling a vertical rod in the lifting mechanism to be in contact with the object so that the object is prevented from slipping from the turntable during the rotation ofthe turntable, thereby ensuring smooth scanning.

Description

Technical field [0001] The present invention relates to the field of scanning equipment, in particular to a 3D scanning equipment based on Internet of Things control. Background technique [0002] The purpose of a 3D scanning device is to create a point cloud of the geometric surface of an object. These points can be used to interpolate the surface shape of the object. The denser the point cloud can create a more accurate model. If the scanning device can obtain the surface color, it can be further pasted on the reconstructed surface, which is the so-called texture mapping. The 3D scanning device can be simulated as a camera, and their sight range is conical, and the collection of information is limited to a certain extent. In the range. The difference between the two is that what the camera captures is color information, while the 3D scanning device measures distance. [0003] Because the scanning range of the 3D scanning device is limited, it is often necessary to place the obj...

Problems solved by technology

However, in the actual use of the existing 3D scanning equipment, the equipment must first be placed on a horizontal platform. When the platform angle is inclined, some items with smooth surfaces are easy to slip off the turntable. Not only that, but when scanning some special-shaped objects (such as smooth spherical objects), due to the lack of corresponding fixing devices, the object will also rotate with the turntable during the rotation of the turntable, and even slip off the turntable, resulting in the failure of the scanning work
