在Blender中使用Perspective Plotter将相机与图像进行匹配，Perspective Plotter是一款供建模者、建筑师和艺术家使用的交互式Blender插件。这对于从二维草图创建三维模型、将三维场景与二维照片匹配或动态设置相机动画非常有用。

在视口中定义透视线可实时设置相机的焦距、位置和位置。该附加组件还可以与场景中的多个摄影机配合使用。其他工具允许您匹配相机的背景图像比例，沿视图线快速移动顶点或对象，并自动展平地平线。

What is Perspective Plotter?

Match a camera to an image with Perspective Plotter, an interactive Blender add-on for modelers, architects and artists. This is useful for creating 3D models from 2D sketches, matching a 3D scene to a 2D photo, or animating a camera dynamically. 

Defining perspective lines in the viewport sets a camera’s focal length, location and position in real time. The add-on will also work with more than one camera in a scene.

Additional tools allow you to match a camera’s background image proportions, quickly move vertices or objects along the view line, and automatically flatten the horizon.

The add-on is inspired by the freely available fSpy application, with the added benefit of being directly inside Blender.  

This add-on assumes understanding of 1, 2 and 3 point perspectives as well as a working knowledge of Blender.

Features

Dynamically match the camera in real time using perspective guides.

Choose from 1, 2 or 3 point perspective modes.

Determine scale of the scene using a measuring guide.

Animate the camera using keyframe buttons.

Match background image proportions.

Flatten horizon line automatically.

Customize colors and opacity of guide lines.

Freeze guides in place to prevent accidental changed.

Use the bundled Move Along View tool to help model 3D meshes from 2D sketches.

Change axes of vanishing points.

Change camera midpoints and camera target location.
