  5. Kinect歷史 Ｋｉｎｎｅｃｔ外型 http://0rz.tw/f9EsR Ｋｉｎｎｅｃｔ http://www.xbox.com/zh-TW/kinect/ Ｗｉｉ http://www.elotrolado.es/tag/wii/ Ｗｉｉｍｏｔｅ http://www.wiiphysics.site88.net

  6. Kinect歷史 Light coding技術 而什麼樣的技術 導致kinect脫穎而出呢? 左圖為Light coding中的雷射散斑現象 http://www.uns.org.tw/node/417 ←

  7. Kinect歷史 http://0rz.tw/BlYyK

  8. Kinect構造 3D深度感應器(左右)： 由光源發出紅外線脈衝光照射被攝景物，而反射回來的紅外線則由 CMOS 影像感測器接收，再傳送到整合系統晶片，產生代表被攝景物距離的 VGA 解析度深度圖像，最後透過 USB 2.0 介面傳輸到主機進行進階辨識。 RGB視訊彩色攝影機(中)： 將來自鏡頭光學圖像聚焦，經由CCD轉換為隨時間變化視頻訊號，再傳送到整合系統晶片，產生被攝景物顏色彩色圖像，最後透過 USB 2.0 介面傳輸到主機進行進階辨識。 陣列式麥克風(左1右3)： 藉由多組麥克風同時收音，比對後消除掉雜音，有效過濾背景聲音，接著會經過程式配合鏡頭所識別使用者正確位置後，即可將語音識別擷取範圍鎖定在使用者身上，而不會識別到其他使用者所發出的聲音。 內建馬達運作： 讓Kinect可作27度的上下調整，同時提供Kinect自動調整焦距的功能，同時配有內建散熱風扇。 http://0rz.tw/RBpgk http://0rz.tw/dxMJU

  9. Kinect功能 因此使得人體可以直接做為控制器而不需要任何的儀器來幫助操控 建立數位骨架，處理使用者的動作，亦可準確分辨不同使用者的動作 每個人在使用之前都須登錄，而記錄每個使用者的身體資料 辨識使用者聲音，濾掉房間的雜音，進而使用語音來控制kinect http://0rz.tw/rmJRj

  10. 3D Motion sensor

  11. There many methods for optical 3D mapping (i)laser speckle (ii)astigmatism (iii)diffraction and so on…. Light coding

  12. What is laser speckle?? • REF: http://www.futurepicture.org/?p=116

  13. IRlaser diode (class 1) (750~900nm)(12A) Diffuser:光柵、擴散片.. (12B) Astigmatic optical element(12B) Ref: ZeevZalevsky, Alexander Shpunt, AviadMaizels,JavierCarcia” Method and system for object reconstruction”

  14. Astigmatism • Ref: Barak Freedman,AlexanderShpunt, YoelArieli “Distance-Varying illumination and image technology depth mapping”

  15. F a 根據相似三角形 可以推得長度x(46) 　　　　　長度y(60) x= (F-f)a/F , y= (F-f)b/f 同理如果距離astigmatic optical element為z時 就可以算出z所在位置 的長短軸長度 f b

  17. Ref: ZeevZalevsky, Alexander Shpunt,” Three-dimensional using speckle patterns”

  18. Skeleton Tracking • Ref:http://msdn.microsoft.com/en-us/library/hh438998.aspx

  20. Time-of-Flight (TOF)

  21. Principle Light source (Laser Pulse) Target Lens Sensor d

  22. Application – 3D Scanner Ref:http://herkules.oulu.fi/isbn9514269667/html/c305.html

  23. People tracking Ref: Alessandro Bevilacqua, Luigi Di Stefano, PietroAzzari “People tracking using a Time-of-Flight depth sensor”

  24. Kinect application

  26. Q&A

  27. Light coding的技術是要獲得什麼資訊? Question 1

  28. Skeleton Tracking是辨識人體上多少的關節來判斷人的動作? Question 2
