在3D polygon Triagulate (之二)这一篇里前几步里有很有意思的操作: ... Project the points to the plane. Transform the points into the coordinate system of the plane, so that every point has a 2D coordinate (x, y) and a depth z ... 这里就来看一下 Project the points to plane 这个操...

A branch point was classified as a node with two or more offspring nodes, with the branch number equating to the total of these points. Each neuron possessed multiple terminals projecting onto the cortex. The length from the neuronal soma to each cortical terminal was defined as an axonal ...
refractive properties of the thin less would effective create a cone that pentrates through the plane of focus, where a circle of rays coming from beyond the plane of focus would focus onto a single point on the lens, causing all their rays to blend into one, resulting in the blurry ...
Finally, we have a way to transform some arbitrary 2D point (a, b) on the image to a 3D point on the virtual screen.That formula inspired these additions to Vec:// p = o + p[0] u + p[1] v public static void map( double[] p, double[] o, double[] u, double[] v) { ...
Those matches from the first frame with a valid LiDAR depth are lifted to 3D to obtain 3D-2D matches between the first and second frame. We then use the 3D- 2D matches to solve a Perspective-n-Point (PnP) problem with RANSAC, which estimates a relative pose between the two frames. ...
