在本視頻教程中,我使用Raspberry Pi 4通過USB從便宜的360度LADR / LiDAR(YDLIDAR X4)讀取數據。一旦能夠獲得距離測量值,我便繼續在Python中設計一個Web界面,該界面使我可以可視化極坐標圖中的數據。我將JavaScript庫D3.js / Plotly(https://plot.ly/javascript/)用於客戶端圖表,並將Flask Web微框架用於設置Web應用程序的伺服器端。其核心是使用Websocket在伺服器和客戶端之間交換LiDAR數據。為此,我使用了Flask-SocketIO模塊。
該項目的代碼:

我在上一個視頻中廣泛介紹了websockets:
我們之前已經設置了基於Linux的Raspbian操作系統,如下所示:
