In the process of car design, we need to convert the shape of the surface of the object into three-dimensional data that the computer can understand through a way called "data acquisition". It's like "photographing" the surface of a model car with a special camera, but this "camera" can record every detail of the object. This data helps designers modify the model and ultimately create the desired car appearance.

Why use clay models?

In the early stages of car design, designers usually make a model of the shape of a car out of clay. Clay models not only show the effect of the design, but also allow the team to discuss and improve the design more intuitively. This is a very important part of car development.

With the help of 3D scanning technology

In order to ensure that every detail of the clay model can be accurately translated into digital information, we use a technique called "contactless 3D scanning". In simple terms, this technology can accurately "scan" out the shape data of the model without touching it, and transfer it to the computer. This method can completely avoid deformation of the model, which is especially important when dealing with volatile materials such as clay.

How a handheld 3D laser scanner works

One common tool is a handheld 3D laser scanner, which is like a "laser camera" that you can hold in your hand. When a designer uses it to scan a clay model, it fires a laser and then records the shape of the model's surface by calculating the Angle at which the laser reflects back. The scanner is fast and accurate, allowing designers to make subsequent changes and improvements more quickly.
