Guanyun photography

Imagine a pile of scattered point cloud data, with no regularity at all. But through our magical technology, these point clouds will be transformed into a continuous and regular surface model. The process behind this is actually not simple. Let's reveal the secret together:

data acquisition

First of all, we need to capture these scattered point cloud data one by one through 3D scanner or photography technology. These data, like stars, illuminate our 3D world.

pretreatment

After the acquisition, in order to ensure the high precision and high efficiency of reconstruction, we will carry out a series of preprocessing operations, such as denoising, data simplification, point cloud registration and so on. Just like screening and sorting the stars, just for better presentation.

surface fitting

Next, we map these stars and clouds onto a surface model to form a continuous three-dimensional surface. It's like connecting the stars in series to form a beautiful sky map.

Parameterization

In order to make this picture more regular and easier to handle, we will parameterize it and map the surface to a regular parameter domain. It's like adjusting the colors and lines of a picture scroll with a brush to make it more perfect.

Optimize

According to the demand and data characteristics, we will further adjust and optimize the surface to achieve higher accuracy and better fitting effect. It's like putting the finishing touch on a picture scroll to make it more vivid and real.

show

Finally, the complete surface model is displayed by rendering, animation and other means for everyone to observe, analyze and apply. It's like showing you a beautiful picture. It's amazing.
