How to Use Laser Scanning to Create Accurate 3D Models

Laser scanning is an advanced technology that is used to create highly accurate 3D models of objects. This technology is used to measure the size, shape, and dimensions of an object in three-dimensional space. It is used in a variety of industries, from automotive and aerospace engineering to architecture and archaeology. The technology is also used for reverse engineering, creating highly detailed 3D models for use in virtual reality and video games.

What is Laser Scanning?

Laser scanning is a non-contact, high-resolution imaging technique that uses a laser beam to measure the shape and size of an object. The laser beam is projected onto the object and is then reflected back to a receiver. This reflection is then used to create a 3D map of the object, which can be used to create highly detailed 3D models.

Advantages of Laser Scanning

Laser scanning has a number of advantages over other methods of 3D modeling. It is highly accurate, with measurements accurate to within 0.03 mm. It can also capture a large number of points in a short amount of time, making it ideal for creating large or complex 3D models. Additionally, the technology can be used to scan objects which are not directly visible, such as objects behind walls or inside other objects.

How to Use Laser Scanning to Create 3D Models

Using laser scanning to create 3D models is relatively straightforward. The first step is to set up the laser scanner, which involves positioning the scanner at the desired location and setting up the software. Once the scanner is set up, it is used to scan the object and collect data points. This data is then used to create a 3D model of the object.

Software for Laser Scanning

Once the data has been collected, it must be processed in order to create a 3D model. This is done using 3D modeling software such as Autodesk ReCap or 3D Systems Geomagic Control. These programs allow users to manipulate the data and create a detailed 3D model.


Laser scanning is a powerful tool for creating highly accurate 3D models. It is used in a wide range of industries and is capable of producing highly detailed models in a short amount of time. By following the steps outlined above, you can use laser scanning to create accurate 3D models of any object.
