Cloudcompare & PCL point cloud equally spaced slices

One 、 brief introduction

Here I draw on PCL The idea of direct filtering in , Through to z The size of the value field is compared to obtain each slice point cloud , The difference is that I do equidistant slice processing for point cloud data , It is mainly for the subsequent implementation of the platform method to calculate the crown volume , As shown in the figure below . In addition, it is to realize the slicing function faster , A parallel method is used to obtain the point cloud data of each layer .

Two 、 Implementation code

For related configurations, please refer to the article https://blog.csdn.net/dayuhaitang1/article/details/124503487 Non plug-in basic configuration in , The core code is as follows ：
