Detailed explanation of camera model and de distortion method

We are all familiar with cameras, which can map point sets in 3D space to 2D planes. This mapping process needs to be described by geometric model. The simplest and most basic model is the pinhole camera model, which describes the basic projection and imaging inertia of the camera. However, our commonly used cameras have lenses. Because o ...
