PCL Euclidean Distance Clustering Source Code Analysis

I spent some time looking at the relevant algorithms and took a simple note.

The specific implementation method of the Euclidean algorithm is roughly as follows:

PCL computing point cloud AABB and OBB bounding box ( C++ code)

method 1: use getMinMax3D Compute way…

PCL Principal Component Analysis (PCA) in 3D Point Cloud C++ code

This C++ code perform Principal Component Analysis (PCA) on a 3D point cloud and project pointcloud to the space spanned by the eigenvectors

Determine if a point is inside a polygon (C++ code)

I tested the code and made a few small changes to improve the efficiency.

Determine whether it is inside the polygon based on the number of intersection points between points and the edges of the polygon

Conversion between QByteArray and Signed Integer (int)

About the decimal to hexadecimal signed conversion method:

hexadecimal Converts to a signed decimal number (-128–127)
The first bit is used as the sign, 0 is a positive number and 1 is a negative number.

JPG image convert to NV12 format (C++ code)

Using the opencv function, transferring a JPG image to NV12 format is divided into two steps:

Convert the BGR format to I420.
Convert the I420 format to NV12 or NV21.

C++ code NV12 format to BGR

This function processes each pixel in the input NV12 image, converts the YUV values to RGB, and stores the result in the output BGR image. It handles the subsampling of the U and V components by calculating the correct index for them and ensures that the RGB values are within the…

C ++ splits a string with a comma or other symbol, and then converts the result of each split into a floating or int value and saves it to a list

The code initializes inputto “1.1, 2.2, 3.3, 4.4, 5.5”, then splits the string with…
