摄像机通过成像透镜将三维场景投影到摄像机二维像平面上，这个投影可用成像变换描述，即摄像机成像模型。摄像机模型可将空间点的世界坐标变换为图像坐标及像素坐标。本例子提供线性及非线性模型的一种matlab实现方法，仅供参考。-Camera lens through the imaging camera will be projected onto three-dimensional scene on a two-dimensional image plane, the projection image transformation can be described, that the camera imaging model. Camera model space can be transformed into world coordinates of point coordinates and image pixel coordinates. This example provides a linear and nonlinear models matlab implementation for reference purposes only.
