中文摘要

本論文主要利用友晶科技公司所開發的Altera DE2-70 多媒體開發平台來設計一個遠端指尖虛擬觸碰控制器。目的是讓使用者在不需要配戴任何裝置及實際接觸控制面板下,就能簡單地以指尖虛擬控制音樂之播放。本論文首先利用數位相機來擷取手部影像,並利用膚色偵測方法來判斷手掌所在之位置。接著將背景雜訊濾除後,再以指尖偵測方法來判斷手指隔空觸碰功能面板之對應位置,以控制驅動不同之音樂播放功能。使用者可分別選擇六種功能:音樂播放、前一首、下一首、音量增加、音量降低及停止等。為了達到即時影像處理之要求,以硬體描述語言Verilog 來撰寫影像處理演算法程式,並使用FPGA 硬體來實現本設計。本研究成果未來除了可以提供銀髮族在控制家電用品便利性外,另應可延伸至其他電子消費產品之虛擬觸碰控制需求。

英文摘要

This paper uses the Altera DE2-70 Multimedia platform created by Terasic to design a virtual-touched control music player. The aim is to let the user can easily control the music playing without wearing any devices. At first, the digital camera is used to capture the image and the hand area is decided by skin detection. Then the fingertip is detected to determine its position corresponding to the location on the touch panel. Image processing techniques are adopted to filter out the noise and the location on the touch panel is utilized to decide the touched music player function. The captured image is displayed on the touch panel and the play functions can be chosen by the user are play, previous song, next song, volume up, volume down, and stop. To fulfill the requirement of real-time image processing, Verilog language is used to implement the control programs and the hardware is designed by using FPGA. The achieved research results can not only be applied to those products of consumer electronics where the virtual-touched control is required, but also used to help senior citizens to improve their living convenience.
