PID control

【实例简介】

以python语言为平台，对机载激光雷达原始数据Las格式和txt格式进行读取，并根据信息熵确定维度特征计算的最佳邻域半径，最后计算得到最佳邻域半径和最佳维度特征值(Based on Python language, the Las format and TXT format of airborne lidar raw data are read, and the optimal neighborhood radius is determined according to the information entropy. Finally, the optimal neighborhood radius and the optimal dimension eigenvalue are calculated.)

说明：  行人的检测使用库函数OpenCV里已经内置的行人检测方法，调用OpenCV预先训练好了的HOG+线性SVM模型，能够对图像和视频中的行人进行检测，系统会分别使用两种算法通过矩形条框将图片中的行人框出来。(Pedestrian detection uses the built-in pedestrian detection method in OpenCV library function, calling the pre-trained HOG + linear SVM model of OpenCV, which can detect the pedestrians in images and videos. The system uses two algorithms to frame the pedestrians in pictures through rectangular bars.)
