说明：  基于PCL的点云滤波中的体素栅格滤波算法，将点云数量过于庞杂的点云文件进行简化但保留其特征，减少后续处理的计算量(PCL VoxelGrid filter)

说明：  Zigzag和iZigzag的程序及改进的Zigzag和iZigzag的程序。后者可以大幅提高运算效率(Zigzag and iZigzag procedures and improved Zigzag and iZigzag procedures. The latter can substantially increase the computing efficiency)

flac3d中邓肯张自定义本构模型的源代码。(duncan self-defined model)

用于点云切片功能的实现，非常好用，可以计算密度、厚度、等内容(For point cloud slicing feature to achieve very easy to use, you can calculate the density, thickness, etc.)

对图像的特征向量进行降维处理，降低代码复杂性，提高目标检测准确率(The dimension of feature vectors extracted image can be reduced by the code. Also, the code complexity is decreased, accompanying with the improved precision of object detection.)

最大类间方差法是由日本学者大津(Nobuyuki Otsu)于1979年提出的,是一种自适应的阈值确定的方法,又叫大津法,简称OTSU。它是按图像的灰度特性,将图像分成背景和目标2部分。背景和目标之间的类间方差越大,说明构成图像的2部分的差别越大,当部分目标错分为背景或部分背景错分为目标都会导致2部分差别变小。(The largest between-class variance method was proposed by the Japanese scholar Nobuyuki Otsu in 1979. It is an adaptive threshold determination method, also known as the Otsu method, or OTSU for short. It is based on the grayscale characteristics of the image and divides the image into two parts: the background and the target. The larger the variance between the background and the target, the greater the difference between the two parts that make up the image. When the part of the target is wrongly divided into backgrounds or part of the background is mis-divided into goals, the difference between the two parts will be smaller.)
