Camera PnPoint 是 Blender 的附加组件，它为相机跟踪工作台带来了强大的Perspective-n-Point求解器。PnP 是根据给定的一组 3D 点及其在图像平面中的 2D 投影来估计校准相机的姿态的问题。该插件还包括一个相机校准解算器，允许使用来自 3D 和 2D 标记的投影数据调整最相关的镜头参数，如焦距和径向畸变。PnP算法与其他透视匹配工具的主要区别在于，它不需要具有多个消失点的图片，也不需要具有平行线的物体。此外，与内置的相机运动求解器不同，该插件依赖于真实的 3D 位置，并且只需要一张静止图片即可找到相机姿势。
支持Blender 2.93、3.0、3.1
Camera PnPoint is an add-on component of Blender, which brings a powerful Perspective-n-Point solver to the camera tracking workbench. PnP is the problem of estimating the attitude of the calibration camera according to a given set of 3D points and their 2D projections in the image plane. The plug-in also includes a camera calibration solver that allows you to adjust the most relevant lens parameters, such as focal length and radial distortion, using projection data from 3D and 2D markers. The main difference between PnP algorithm and other perspective matching tools is that it does not require images with multiple vanishing points, nor objects with parallel lines. In addition, unlike the built-in camera motion solver, the plug-in relies on the real 3D position and only needs a still picture to find the camera pose.
Supports Blender 2.93, 3.0, 3.1
