A kind of 3D scanning devices based on Internet of Things control
Technical field
The present invention relates to scanning device field, more particularly to a kind of 3D scanning devices based on Internet of Things control.
Background technology
The purposes of 3D scanning devices is to create the point cloud (point cloud) of object geometric jacquard patterning unit surface, and these points can be used for
Into the surface configuration of object, more intensive point cloud can create more accurate model for interpolation.If scanning device can obtain surface
Color, then further it can be pasted on the surface of reconstruction, that is, so-called texture mapping, 3D scanning devices can
Camera is modeled as, their visual line of sight all embodies coniform, and the collection of information is all limited in certain scope.Both are not
Be that camera captured with part is colouring information, and the measurement of 3D scanning devices is distance.
Because the scanning range of 3D scanning devices is limited, therefore often need object being positioned on electric turntable to sweep to change
The relative position of instrument and object is retouched, by multiple scanning to piece together the complete model of object.But existing 3D scanning devices
In actual use, first have to equipment being positioned on horizontal platform, when platform angle tilts, some surfaces are smooth
Article easily slides from rotating disk, moreover, is scanning the object (the smooth spherical object in such as surface) of some special shapes
When, due to lacking corresponding fixing device, cause in rotating disk rotation process, object can also rotate with rotating disk, or even can also be from turning
Slid on disk, so as to cause the failure of scanning work.
