The term 3D scanning implies the process of capturing the digital visual information from a real-world object. This information is then feed to computers and translated to a virtual 3D object.
3D scanning is also known as 3D Imaging, Laser Scanning, Laser Digitizing, and Digital Shape Sampling & Processing (DSSP).
The device found in this process is known as a 3D Scanner. It is an imaging device that uses a laser or light to basically measures the distance between the scanner and the object.
It is a really fast and reliable way of putting visual measurements associated with an object into a computer.
The resulting data are further organized to what is commonly called the 3D scan data. 3D scanning can not only capture data of very small objects but also large enough like a full size aircraft or a building.
It can be used for reverse engineering, computer-aided inspection, or simply documenting the shape for future use.
Nowadays, in conjunction with 3d printers, 3d scanning has grown more popular than ever.
After scanning, you can upload the scanned 3D model on your computer for processing by a 3D modeling software for making images or videos. It is also possible to utilize the models that you just scanned for 3Dprinting.
3D scanning can be a superior technique and technology that presents real-world imagery of surroundings and objects. It gives construction workers and engineers the opportunity to model their plans by materializing in real world existing landscapes.
In the office and home environment, 3d scanners are used to capture the 3d image of real objects and feeding the information to a computer for further processing and printing.
Without a 3d scanner you must either create the virtual object on the computer or use a ready-made design for 3d printing.
