官网节点介绍（机翻）：

Reconcile3D turns a point in 3D space into an x, y position in the camera. The 3D point is controlled by the first fields in the properties panel, and by the optional Axis input. The point is projected through the camera to the image and the position of the result is put in XY output. In addition, the absolute 3D point is put in XYZ output (this is only useful if there is an Axis parent, otherwise it is the same as the input point). This lets you lock a photographed plate to a 3D scene or track.

Reconcile3D 将 3D 空间中的点转换为相机中的 x、y 位置。 3D 点由属性面板中的第一个字段和可选的轴输入控制。 该点通过相机投射到图像上，并且把得出的位置信息输出到XY output参数上。 此外，绝对 3D 点放在 XYZ 输出中（这仅在有 Axis 父级时才有用，否则与输入点相同）。 这可以使您可以将拍摄的镜头图像锁定到 3D 场景或跟踪中。
