Two ways to use PCL computing point cloud maximum axis value

way one:

**Load PCD File**: The `pcl::io::loadPCDFile` function is used to load point cloud data from a PCD file named “bunny.pcd” located in the “data” directory into the `cloud` object.

Calculate The Area of Point Cloud Grid Method by Open3D python

This method is mainly used for rough airborne statistics point cloud of The floor area.

The principle of themethod is to place the point cloud along XOY The surface, then the pointcloud is divided…

PCL reconstructs point cloud convex hull and visualizes it

First, choose a tetrahedron (initial convex hull) formed by 4 points, and then add a new point P each time, divided into two cases:
1.P is in the convex hull, you can skip it

Two ways to use PCL reads STL files and covert to PCD

method one:

Read an STL file, convert it to a point cloud, and visualize it.

**Read CAD Model**: A `vtkSTLReader` object is created to read an STL file. The file path is set, and the…

Surface Reconstruction Based on B-Spline Curve in PCL

This code run a B-spline fiting algorithm on a point cloud Q to obtain a smooth, parametric surfacere presentation.

Steps:

PCL calculates the coordinates of the maximum point

The use of the `std::minmax_element` function to find both the minimum and maximum elements in a container.

**Array Initialization**: A `std::array` named `foo` is declared and initialized with seven integers: `{3…
