A kind of 3D scanning device based on Internet of Things control
Technical field
The present invention relates to scanning device field, in particular to a kind of 3D scanning device based on Internet of Things control.
Background technique
The purposes of 3D scanning device is the point cloud (point cloud) for creating object geometric jacquard patterning unit surface, these points can be used to
At the surface shape of object, more intensive point cloud can create more accurate model for interpolation.If scanning device can obtain surface
Color then can further be pasted on the surface of reconstruction, that is, so-called texture mapping, and 3D scanning device can
It is modeled as camera, their range of visibility all embodies coniform, and the collection of information all limits in a certain range.The two is not
Be that camera grabbed with place is colouring information, and the measurement of 3D scanning device is distance.
Since the scanning range of 3D scanning device is limited, often needs for object to be placed in and be swept on electric turntable with variation
The relative position for retouching instrument and object pieces together the complete model of object by multiple scanning.But existing 3D scanning device
In actual use, it first has to for equipment being placed on horizontal platform, when platform angle inclination, some surfaces are smooth
Article is easy to slide from turntable, moreover, in the object (the smooth spherical object in such as surface) for scanning some special shapes
When, due to lacking corresponding fixed device, cause in turntable rotation process, object can also be rotated with turntable, or even can also be from turning
It is slid on disk, so as to cause the failure of scanning work.
