Comparison of 3D scanners: Shining 3D Einscan-SP vs RangeVision Spectrum
If you want to understand the simple and budget models of color 3D scanners, our review is for you. Today we will compare models RangeVision Spectrum and Shining 3D Einscan-SP – low-cost devices with high performance. In our article you will get acquainted with the characteristics of devices, their features, strengths and weaknesses, fundamental differences.
Einscan-SP – a 3D scanner from Shining 3D, – a Chinese developer and manufacturer of digital equipment: 3D printers3D scanners, related products. The company has been known on the world market for more than 15 years due to the high quality of its products and the active position of the manufacturer: Shining 3D devices are presented at leading industry exhibitions and are covered on thematic online and offline platforms.
Einscan-SP is an inexpensive scanner, which is one of the important advantages of the device. Other advantages of the model include: the ability to color scan, intuitive interface, easy setup. To work with small objects (up to 0.2 m), a rotary platform is used. Note that a black-and-white model when scanning on the platform is obtained in just a few minutes (the exact time depends on the capabilities of the computer).
To work with larger items – up to 1.2 m on each axis, no rotary table is used. The accuracy of the models is 50 microns.
All work items, a projector and 2 cameras are enclosed in one housing. Before starting a scan, you need to install the work module and platform on any suitable flat surface with a hard base.
Description of Spectrum
RangeVision Spectrum – Russian 3D-scanner. RangeVision has been working in the field of digital technology for over 10 years. Despite the fact that the company’s products are professional devices, the manufacturer manages to launch relatively inexpensive models on the market. Budget 3D-scanner works in black and white and color modes. Plus models – in a large working field: the device works with objects up to 3 m in size on each axis. Due to the high resolution of 60 microns, the device is used in many fields. Inexperienced users may spend a little more time setting up the device than setting up their Chinese counterpart.
Options Einscan-SP and Spectrum
In the package with the Einscan-SP scanner you will find all the necessary accessories for the job:
metal base;
a tripod – very convenient, built into the turntable;
calibration kit;
all necessary cables;
a package of documents.
Options Spectrum is similar to a set of Chinese-made, however, it is worth noting that the entire set of equipment is packed in a durable case, which is usually supplied with more expensive devices. Yes, and the tripod is much more serious here, because it is not a desktop, but an outdoor device.
Package Contents:
3D scanner;
swivel platform up to 5 kg included
optionally a platform of up to 60 kg is bought in;
tripod;
magnetic stand and set of calibration boards;
all necessary cables;
USB hub
set of documents;
set of stickers.
Preparatory work for Einscan-SP
As we have already noted, the simplicity of the preparatory work is an important competitive advantage of the model. The software controls the algorithm, showing each next step to the user. To start the workflow, you just need to install the calibration board on the stand and observe the automated actions of the software. If you are using a turntable, you will need to reposition the board 90 degrees. To adjust the white balance, a sheet of white paper is placed opposite the scanner, the device is automatically configured.
You can digitize an object with and without tags. When working on a turntable, they are not needed. The software monitors the parameters of the image: if there are problems with exposure, the program gives a signal and suggests making adjustments.
Preparatory work for Spectrum
It takes more time to set up this appliance. First you need to mount the projector on a tripod and install the camera on the slider. Preparing cameras requires operator intervention: aperture adjustment and focusing are manual. The quality of the finished model depends on the attention and experience of the operator. After setting up the cameras, the calibration process begins. The calibration board moves within the workspace until the cameras take eleven different frames. When digitizing large items, you must use monochrome stickers.
The entire product line of Shining 3D scanners is powered by the EinScan Software suite. The developers have created an understandable program with a number of tips for the user. It is possible to combine several images at the corresponding points to obtain a complete picture.
ScanCenter NG provides RangeVision 3D scanners. This is a software with wide capabilities, but an accessible interface. The program is also able to “collect” the whole image from several pictures in automatic or manual modes.
Case Shining 3D Einscan-SP
Holster Design
The American developer of military equipment was faced with the task of creating an innovative holster for weapons complete with a flashlight. The accessory had to meet a number of requirements: to have a rigid structure for reliable fixation and to allow quick extraction of contents. T.REX ARMS engineers scanned the gun using the Einscan-SP and designed a holster based on the finished model.
The objective of the graduation project of students of the Moscow Polytechnic University was to improve the aerodynamics of a sports car. To digitize the body chose Spectrum. Using tags and photogrammetry technology, experts created a model of individual scanned elements in just 1 business day.
Compare Models
To summarize and highlight the strengths of RangeVision Spectrum and Shining 3D Einscan-SP scanners.
Shining 3D Einscan-SP has proven itself in the following ways:
The convenience of use;
Simple calibration
Quick model creation;
Budget cost.
Strengths of RangeVision Spectrum:
Scans objects up to 300 cm in size;
It is equipped with a durable case.
Summary
Shining 3D Einscan-SP and RangeVision Spectrum – Professional equipment that perfectly copes with the digitization of objects, performing the tasks of reverse engineering and prototyping. High resolution color scanning is an undeniable advantage of both models.
This is where the similarity of models ends.
The Chinese scanner is suitable for even inexperienced users. All you need to get started is to connect it to a computer and follow the recommendations of the program. The size of scanned objects is limited to 120 centimeters on each side. The scanner is ideal for 3D shooting of a large number of small items, for example, when creating a jewelry catalog or wearable electronics with 3D illustrations. It can also be used for reverse engineering of small parts.
The Russian Spectrum is closer to professional devices than amateur ones. It works with objects up to 300 cm, it requires some experience to customize. Comes with a convenient shipping case in which the necessary accessories are placed. It is rather an industrial tool, for the simple digitization of goods on the site, it will be redundant.
Briefly summarizing: Shining 3D Einscan-SP – a model for novice users and simple tasks, RangeVision Spectrum more suitable for technical specialists for professional use.
