基于人體動(dòng)作識別與語(yǔ)音識別的舞蹈機器人

—— ——2008年英特爾杯大學(xué)生電子設計競賽嵌入式系統專(zhuān)題邀請賽作品簡(jiǎn)介
作者:鄧磊,薛源海,代明月,吳瓊之 北京理工大學(xué) 時(shí)間:2008-11-10 來(lái)源:電子產(chǎn)品世界 收藏

本作品是一個(gè)以EC5主板為平臺構建的多功能智能舞蹈機器人DDX-08。它具備單目視覺(jué)能力,通過(guò)人臉識別算法和跟蹤算法,實(shí)現了人體動(dòng)作的識別和跟蹤。在開(kāi)源的語(yǔ)音開(kāi)發(fā)包SAPI的支持下,通過(guò)語(yǔ)音識別,語(yǔ)音合成和圖形界面完成友好的人機交互。通過(guò)自行設計的驅動(dòng)電路控制執行機構協(xié)調地完成了機器人的動(dòng)作。安裝了履帶底盤(pán)和電池后,DDX-08實(shí)現可移動(dòng)性。自制的機器人框架不但使結構穩定,而且保證了各硬件模塊的良好散熱。

復雜背景下無(wú)任何傳感器的人體手臂動(dòng)作的識別和跟蹤是本作品最大的特色和創(chuàng )新。改進(jìn)的CAMSHIFT算法在其中起了關(guān)鍵性作用。DDX-08的創(chuàng )新在于通過(guò)控制伺服電機將識別的結果直觀(guān)地展現在用戶(hù)眼前。分層結構設計是本作品機械部分的主要特色。此外DDX-08還實(shí)現了非特定人語(yǔ)音的識別。

使用時(shí),用戶(hù)需穿長(cháng)袖。用戶(hù)需要先做一個(gè)初始動(dòng)作對DDX-08進(jìn)行標定,隨后DDX-08便可模仿表演者的手臂平面動(dòng)作。結合語(yǔ)音,它可以實(shí)現智能學(xué)習功能。用戶(hù)將語(yǔ)言和舞蹈教給機器人后,便可通過(guò)語(yǔ)音控制DDX-08表演學(xué)會(huì )的動(dòng)作。

DDX-08 is a multi-purpose intelligence dancing robot based on EC5-1719CLDNA, which can identify and track human motion through monocular machine vision and tracking algorithm under complex background. With the advantage of open source SAPI, DDX-08 can complete the human-computer interaction through the speech recognition, speech synthesis and the graphical interface. The human motion is determined by servo motor and DC motor which is controlled by the driving circuit. The robot can be mobile after installing the caterpillar band chassis and the battery in it. With the self-made frame, the structure becomes stable and good to heat dissipation. 

It is human motion recognition and tracking without sensor in complex background that DDX-08 mostly features for, in which CAMSHIFT algorithm plays a key role. DDX-08 also features for that the result of recognition can be shown with the servo motors and DC motors control system. Part of the main characteristic of our machine is manifested through the concept of stratification structure design. In addition, speech recognition of non-specific speaker is also a feature of the system.

An initialization pose is required when it is used for the first time, which can be used in system calibration. DDX-08 can imitate the flat motion of the user who requires dressing long sleeves. With voice interactive system, it may realize the intelligent study function. The user can control DDX-08 to perform the dance through voice control.
