A Complete Guide to Choose the Best 3D Handheld Scanner

3D scanning technology has revolutionized various industries, from industrial design to archaeology. In this blog post, we will explore what is 3D scanning technology, how does a 3D scanner work, and the benefits of using a LiDAR 3D handheld scanner. We will also provide tips on choosing the best one for your needs from performance and price perspectives.

What is 3D Scanning Technology?

3D scanning technology is an innovative and advanced process. It involves capturing the precise shape, size, and surface details of physical objects using a digital sensor, such as a camera or laser. The collected data is processed into a point cloud, which represents the object's surface in three-dimensional space. Multiple scans are often needed to create a complete 3D model. And specialized software is used to align, register, and refine the point cloud data. The resulting digital model can be used in diverse applications. For example, 3D printing, virtual reality, and computer-aided design (CAD).

How Does a 3D Scanner Work?

A 3D scanner's working process involves data acquisition, processing, and refinement.

Data acquisition involves capturing the geometric information of the object using either a laser or structured light source. The light interacts with the surface, and the scanner's sensor captures the reflected light. Once the reflected light data is captured, it is processed to create a 3D model of the object. This involves converting the raw data into a point cloud, which contains information about the object's position and surface details.

The 3D model can then be refined and manipulated using specialized software. This may involve smoothing out rough surfaces, filling in gaps or holes, or adding additional details to the model. The final result is a highly accurate digital representation of the object. Thus, it opens up new possibilities and applications for the future.

Benefits of LiDAR 3D Handheld Scanner

Portability

One of the main advantages of LiDAR 3D handheld scanners is their portability. These devices are designed to be lightweight and compact, thus being easy to carry and transport.

User-friendly

Another benefit of LiDAR 3D handheld scanners is their user-friendly design. Most of these devices come with intuitive software and user interfaces. So it is easy to learn and operate, even for those who may not have previous experience with this technology. The software often includes features like automated alignment, real-time visualization, and data processing. Thus, it simplifies the scanning process and achieves accurate results quickly.

Affordability

With advancements in technology, 3D handheld scanner has become more affordable in recent years. This has made them accessible to a wider range of users, from small businesses to individual hobbyists. As a result, more people can now benefit from the advantages of 3D scanning technology. For example, improved accuracy, faster design iterations, and better quality control. This makes it even more accessible and beneficial for various industries and applications in the future.

Wide Application

In addition, LiDAR 3D handheld scanners are also versatile in their applications. They can be used to scan a wide range of objects, from small artifacts to large structures. And the scanners suit various industries like archaeology, engineering, and manufacturing. This versatility makes them a valuable tool for professionals who require accurate and detailed 3D models of objects for their work. A 3D handheld scanner is ideal for industrial design & engineering, forestry & agriculture, and archaeology & heritage preservation.

How to Choose the Best 3D Handheld Scanner?

Selecting the best 3D handheld scanner for your specific needs can be a challenging task. Here, we provide a comprehensive guide to help you make an informed decision:

3D Scanner Accuracy vs. Price

One of the most crucial factors to consider is the level of scanning accuracy it offers. Higher accuracy often comes at a higher cost. So it is essential to strike a balance between your project requirements and your budget.

Determine the level of accuracy required for your project. Before starting your search, assess the level of detail and precision you need for your specific application. For instance, industrial design and engineering projects may require higher accuracy than those in archaeology or forestry.

Compare different models within your budget. Once you have a clear understanding of your accuracy requirements, research various 3D scanner models that fall within your budget. You can compare their specs to select a scanner that offers the best value for money.

3D Scanner Volume and Coverage

Assess your scanning volume and coverage requirements. Determine the size of the objects or environments you will be scanning. And consider if you need a scanner that can cover large areas or focus on smaller, more intricate details.

Evaluate the scanner's specifications. Look for information on the scanner's field of view, depth of field, and scanning distance. These specifications will give you a better understanding of the scanner's capabilities. Then you can determine whether it is suitable for your project.

Consider the portability and ease of use. Depending on your project's nature, you may need a scanner that is easy to transport and operate in various environments. Ensure that the scanner you choose is lightweight, ergonomic, and user-friendly. Then it will be convenient to use in different settings.

Additional Factors to Consider

Software compatibility. Ensure that the 3D scanner you choose is compatible with the software you plan to use for processing and analyzing the scanned data.

Scanning speed. Depending on your project's time constraints, you may need a scanner that can capture data quickly without compromising accuracy.

Customer support and warranty. Choose a scanner from a reputable manufacturer that offers reliable customer support and a good warranty to protect your investment.
