Rhinoceros 3D simulation Pothole


這篇主旨在於使用3D立體模型軟體來製作坑洞，從而獲得大量坑洞資料，減少人工採集資料的時間。

以下會依序介紹路面剖析、模擬坑洞等等。


路面分層

路面坑洞常見形成方式，是在密集配瀝青混泥土層破裂從而導致路面塌陷形成坑洞。

路面分層詳細介紹




柏油路上坑洞形成四大種類



道路寬度

  • 快速道路者，不得小於3.2公尺
  • 於主要道路及次要道路者，不得小於三公尺
  • 於服務道路者，不得小於2.8公尺


坑洞設計



使用Rhinoceros 3D來模擬坑洞形成





簡介：Rhinoceros 3D是一套專業的3D立體模型製作軟體，簡稱Rhino3D

解壓縮：rhinoceros67chs.rar

出現畫面，並選取紅框中安裝



安裝完後，不要啟動，回到原先壓縮檔位置，選取紅框



將紅框檔案移動到，Rhino 6 安裝檔案位置，後可啟動




啟動畫面，在 Command 輸入 Grasshopper，按下 enter





Grasshopper 畫面啟動，點選 File，選取紅框



選取檔案




檔案下載點：https://drive.google.com/file/d/1tT3k-_CUdNnEdOCiXDVUaYFr9AMMHeMx/view?usp=sharing


坑洞生成，選取紅框按滑鼠中鍵



點選 Bake



回到 Rhino 畫面，坑洞形成



存檔(存檔位置自行選擇)，檔案類型選擇 Rhino 6 3D Models(*.3dm)




坑洞形成概念

  1. 先在一個方格內隨機佈點

  2. 框出點的範圍隨機分布

  3. A 點為圓心，B 點為框裡面的隨機點分布，以 AB 畫出向量

  4. 劃出坑洞邊界

  5. 邊界向下延伸，形成柱體


  6. 正方體相減不規則柱體


  7. 形成隨機坑洞大小

ArduPilot Software-In-The-Loop (SITL), MavLink, and AirSim

In this article, I would like to share my experience of setting up ArduPilot SITL running with AirSim using Cygwin on Windows. The result is shown in the picture below. I hope this post can be complementary to the original AirSim SITL tutorial Using SITL with AirSim . First of all, let's see the architecture of AirSim SITL: The red block represents SITL, which connects to physics simulator (blue block), which is AirSim, and a Ground Control System (GCS), which is MAVProxy in our case. So we will run three programs that communicates with each other through TCP/IP.  Now we are ready to run the simulation. The major steps are listed below: Git clone ArduPilot and build it under Cygwin. You can follow ArduPilot tutorial ( link ) or see my summary at the section ( Run SITL using Cygwin ). Install Unreal and git clone AirSim and build it, OR  download pre-built AirSim precompiled binaries ( link ) Edit “Documents\AirSim\settings.json”, note the default folder is your Win

In this blog we will show you how to label actions in drone videos, as shown in the video below: https://www.youtube.com/watch?v=y05iJ0vMnuI We use Microsoft VoTT as our labeling tool. The summary of labeling steps are listed as follows: ' Install Microsoft VoTT v2.1.0 ( link ) or NTUT VoTT v0.0.5 ( Windows ) Add security token to VoTT  Name : NTUTDrone Token Key : qITjd1Rj6hFqC7uB0OGxPKYVxIFSdcMrprQAMS5rEhc= Download Drone videos ( DroneVideos ) and labeling projects ( VoTT Projects ) Create two folders: C:\Drone_Target\ and C:\Drone_Source\ Put VoTT project to C:\Drone_Target\ Put drone video to C:\Drone_Source\ (Make sure ONLY project videos in this folder) Open VoTT project file ( C:\Drone_Target\Drone_001.vott ) Label and check actions ( action_lists ) ( Check Labels ) Let's see the detailed steps now. 1. Install Microsoft VoTT Download VoTT from GitHub ( https://github.com/microsoft/VoTT/releases ). Install and open VoTT 2. Add security toke
