PCL Calculation of intersection between line and plane in point cloud processing （ Fifty-three ）
One 、 It is known that
A point on the line ：（a,b,c）
Line direction vector ：(d,e,f)
A little flat ：(l,m,n)
Plane normal vector ：(i,j,k)
Two 、 To be asked
First step ： Guarantee (i* d+ j* e+ k* f) It's not equal to 0, That is, the straight line is not parallel to the plane , The intersection
if( (i* d+ j* e+ k* f) == 0 )
