3D Reconstruction with Quadcopters Summer Camp 2019

“2019四軸飛行器三維重構夏令營”主要介紹流行的四軸飛行器DJI Spark Fly Drone 及三維重構技術。夏令營有兩天的活動，包括講授與實作課程。學員們在最後部分還有透過使用四軸飛行器Spark Fly Drone對場境進行三維重構的競賽。通過這些活動，學生們將體驗新穎的飛行機器人並認識實用的場景三維重構技術。

“3D Reconstruction with Quadcopters Summer Camp 2019” mainly introduces the basic knowledge of quadcopter using popular DJI Spark Fly Drone and 3D reconstruction techniques, which includes two-day activities such as lecturing and practical courses. At last, the participants will have a competition on 3D reconstruction using Spark Fly Drone. Through these activities, the students will experience the novel quadcopters and learn some practical techniques in 3D scene reconstruction from 2D images.

主題一: 探索四軸飛行器
-四軸飛行器DJI Spark Fly Drone的基本概念及各種功能模塊。
-四軸飛行器DJI Spark Fly Drone的基本操作。
-四軸飛行器DJI Spark Fly Drone的基本編程。

實作一:
學生們透過手提裝置及編程操控四軸飛行器。

主題二: 三維重建 (透過二維圖像 / 光學雷達)
-圖像特征提取及配對
-圖像三維重建的基本概念: 運動恢復結構, 視覺里程計, 視覺 SLAM.
-激光三維重建的基本概念

實作二: 
學生們透過相機/光學雷達設備實現三維重構，並學會如何對三維輸出進行後處理，適用於3D打印。最後，學生分組作賽 — 透過使用四軸飛行器DJI Spark Fly Drone進行三維重構。

Theme one: Exploration of Quacopters
-Basic concept and different functional mechanisms of a quadcopter such as Spark Fly Drone
-Basic operations of Spark Fly Drone
-Basic programming of Spark Fly Drone

Practice one:
Students have opportunity to remote control the quadcopters through handheld device and programming.

Theme two: 3D Reconstruction (from 2D images / LiDAR)
-Image features extraction and image matching
-Basic concept and methods on image-based 3D reconstruction: Structure from motion, Visual Odometry, Visual SLAM.
-Basic concept and methods on laser-based 3D reconstruction.

Practice two:
Students have opportunity to practice 3D reconstruction through hand-held camera / LiDAR and learn how to post-process the 3D output to be suitable in 3D printing. Finally, students will form in groups to have a competition on 3D reconstruction using Spark Fly Drone.
