At present, there are numerous types and brands of 3D scanners on the request. The different dimension principles of 3D scanners are generally different because of the light source and 3D technology used. Photographic 3D scanners use structured light while handheld ray 3D scanners use structured light. It’s a ray, so the measuring principle of the 3D scanner is also different.
1. Measuring principle of camera- type 3D scanner
The 3D scanner is substantially used to overlook the spatial shape and structure of objects to gain the spatial equals of the object face, descry and dissect the shape (geometric structure) and appearance data ( similar as color) of the object or terrain in the real world., Texture and other parcels). The photographic 3D scanner is named after its scanning principle is analogous to that of taking prints with a camera. It’s a product developed to meet the operation requirements of artificial design assiduity. The scanning speed is high and the delicacy is high. The dimension range can be acclimated freely according to the requirements, from small corridors to surveying The overall dimension of the auto body is impeccably competent and has a veritably high performance-price rate.
Principle analysis and affiliated technology
The scanner host is composed of two or further artificial CCD cameras and a grating protuberance unit. The grating protuberance unit is used to project a group of grating circumferences with phase information onto the face of the object to be measured. The cameras measure contemporaneously and combine[ 1 ] Computer vision technology[ 2 ] Photoelectric detector technology[ 3 ] Image processing technology[ 4 ] Software control technology, etc. can gain high-viscosity three-dimensional data on the face of an object in a short time
2. Measuring principle of handheld ray 3D scanner
A handheld ray 3D scanner is a scientific instrument used to descry and dissect the shape (geometric structure) and appearance data ( similar as color, face albedo, etc.) of objects or surroundings in the real world. The collected data is frequently used for 3D reconstruction computations to produce digital models of factual objects in the virtual world. These models have a wide range of uses, similar as artificial design, disfigurement discovery, rear engineering, robot guidance, topography dimension, medical information, natural information, felonious identification, digital artistic bones, film product, game creation accouterments, etc. operation. The product of 3D scanners doesn’t calculate on a single technology. Colorful reconstruction technologies have their advantages and disadvantages, and the cost and selling price are also different. Presently, there’s no universal reconstruction technology, and the instruments and styles are frequently limited by the face characteristics of the object. For illustration, optic technology isn’t easy to handle candescent ( high albedo), glass, or translucent shells, while ray technology isn’t suitable for fragile or perishable shells.
The purpose of the handheld ray 3D scanner is to produce a point pall of the geometric face of the object. These points can be used to fit the face shape of the object. The thick the point pall can produce a more accurate model (this process is called 3D). reconstruction). Still, it can further bury a texture chart on the repaired face, which is so-called texture mapping, If the scanner can gain the face color. The handheld ray 3D scanner is a perfect examination device for assaying and reporting geometric confines and forbearance ( GD&T). The directly generated stl train can be fluently imported into the examination software for quick editing and posterior processing.
3. Measuring principle of handheld white light 3D scanner
The handheld white light 3D scanner uses a new generation of face-grounded optic raster surveying technology. Technically speaking, the raster surveying technology has bettered both in delicacy and speed. Hand-held white light 3D scanners can acquire millions of data points in one checkup. Hand-held white light 3D scanners can acquire further details at one time and have an advanced scanning speed; raster scanning can overlook one face at a time, with in- airplane data. Unconventional, the data of each point is only related to itself. The handheld white light 3D scanner supports two kinds of mark splicing and point splicing. The handheld white light 3D scanner can support one machine with multi-color light.
From the perspective of literal operations, the utmost of the gantry-type ray surveying systems was on the request before 2008, but as the raster machine progressed after 2008, they were replaced in the scanning request, because the camera type has better scanning delicacy, Faster scanning speed, and better rigidity.
4. Measuring principle of bottom-shaped 3D scanner
The bottom-shaped 3D scanner is a computer-backed 3D dimension device that uses a ray line structure light detector. It integrates new technologies in the fields of optics, mechanics, and electronics. It’s ergonomically designed. It adopts a multi-view ray light path design and is equipped with important software. The scrutinized data is displayed in real-time, accurate, presto, important, simple, and easy to use. The complete data of the entire bottom can be attained in a moment, and it can be an affair in a variety of train formats, seamlessly connecting with all kinds of footwear software after a period. The outfit is extensively used in shoe plant R&D and design centers, shoe retail stores, hospitals, conventions, pedicure institutions, universities, exploration institutions, etc. Foot-shaped 3D scanner ray surveying advanced algorithms, short time for data accession,multi-scanning, high data accession delicacy, small size, easy to handle and carry, with bottom-shaped opinion function, a complete set of loss networking results.
Foot ray three-dimensional scanner full light path closed system, 8 viewing angles Omni-directional scanning, surveying objects bases ( bare bases or wearing socks), lasts, cataplasm models, intelligent one-button touch operation, one-button touch operation.
Non-contact ray scanning, no detriment to mortal body and eyes, contemporaneous scanning of both bases, ergonomic design, fast scanning speed (15-20s for both bases), high dimension delicacy ( standard error<0.5mm).
