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。
Camera PnPoint is an add-on for Blender that brings a powerful PnP solver to the camera tracking workbench.Perspective-n-Point is the problem of estimating the pose of a calibrated camera given a set of known 3D points and their 2D projections in the image. Blender features a strong built-in solver for camera pose and feature tracking, but it does not constrain the projected features to known coordinates in the 3D world. The PnP algorithm expands on this functionality by using 3D markers as ground truth for the 2D projections, enabling camera solves that require less points and only one still image.
支持Blender 2.93、3.0、3.1
