Summary of point cloud reconstruction methods I (pcl-cgal)

---

One 、 Preface

A few days ago, I took time to PCL neutralization CGAL Common in Reconstruction methods All ran , Today, I would like to make a summary here .

One 、 The main method ：

PCL	CGAL
Concave bag	Advancing Front
convex hull	Scale Space
Poisson	Poisson
greedy

Two 、 data ：

With bunny Take the data , Show the reconstruction effect

---

Two 、 Effect display

2.1 PCL To realize

1、 Convex hull reconstruction

The convex hull principle and effect are the most intuitive , as follows ：

2、 Concave reconstruction

Among them, the effect of concave reconstruction is similar to Alpha of ,Alpha According to Point cloud resolution Adjustment , Here's a different picture Alpha Value to rebuild the effect .

Alpha=0.5

Alpha=1.5

Alpha=5

Alpha=15

3、 Greedy reconstruction

The effect of greedy reconstruction is as follows ：

4、 Poisson reconstruction

The Poisson reconstruction effect is as follows , The parameter setting needs to be considered .

2.2 CGAL To realize

1、 CGAL The reconstruction process is as follows

2、 CGAL Medium reconstruction effect

1、CGAL The Poisson reconstruction effect is as follows .

2、CGAL in Advancing Front The reconstruction effect of the method is as follows .

3、CGAL in Scale Space The reconstruction effect of the method is as follows .

3、 ... and 、 follow-up

The code will be released later , Or integrated into 《QT+PCL》 in .
