【摘要】：目前,虛擬裝配系統(tǒng)通常依賴力反饋、體感設(shè)備作為交互工具,采用“抓取”、“拖拽”等直觀的手勢(shì)完成產(chǎn)品的裝配。然而,當(dāng)遇到精細(xì)零件模型的裝配時(shí),往往達(dá)不到預(yù)想的結(jié)果。 針對(duì)這一問題,本論文提出了以Kinect體感設(shè)備為輸入,利用中文語(yǔ)音指令識(shí)別引導(dǎo)裝配流程,并設(shè)計(jì)實(shí)現(xiàn)了一套基于中文語(yǔ)音交互的自行車虛擬裝配系統(tǒng),驗(yàn)證了方法的可行性。論文的具體研究?jī)?nèi)容包括： (1)由于基于中文語(yǔ)音交互的虛擬裝配涉及到虛擬環(huán)境的建模、虛擬環(huán)境的渲染、中文語(yǔ)音的識(shí)別等多項(xiàng)技術(shù),因此在虛擬裝配系統(tǒng)架構(gòu)設(shè)計(jì)時(shí)重點(diǎn)考慮了多種軟件的通訊方式,并以自行車虛擬裝配為例設(shè)計(jì)實(shí)現(xiàn)了原型系統(tǒng)。 (2)虛擬裝配環(huán)境的設(shè)計(jì)與仿真。利用3DS MAX完成虛擬裝配系統(tǒng)中零件和場(chǎng)景的建模,利用Photoshop CS6完成交互菜單設(shè)計(jì)和材質(zhì)紋理圖片處理,并在3Dvia Studio Pro中導(dǎo)入場(chǎng)景模型,完成了整個(gè)虛擬裝配環(huán)境的設(shè)計(jì)、場(chǎng)景渲染、裝配序列規(guī)劃等。 (3)為了降低用戶的操作錯(cuò)誤率,提出了一種基于推薦的零件裝配序列規(guī)劃。通過分析零件的物理連接關(guān)系、層次關(guān)系以及同層次下裝配約束關(guān)系,定義了自行車的裝配優(yōu)先級(jí)模型。僅當(dāng)較高優(yōu)先級(jí)的零件完成了裝配仿真,其下一優(yōu)先級(jí)的零件才會(huì)被系統(tǒng)推薦為待裝配零件。 (4)為了解決多人環(huán)境下操作者確認(rèn)問題,提出了一種基于Kinect的中文語(yǔ)音指令識(shí)別的方法,并通過實(shí)驗(yàn)測(cè)試了該方法的識(shí)別準(zhǔn)確度。該方法借助Kinect設(shè)備捕捉多人的骨骼跟蹤數(shù)據(jù),并據(jù)此確定Kinect視野前方一定范圍內(nèi),距離Kinect最近用戶的骨骼信息；然后,利用該用戶頭部的坐標(biāo)信息以及Kinect線性麥克風(fēng)陣列的聲源定位功能確定操作者,實(shí)時(shí)捕獲該用戶的語(yǔ)音指令并進(jìn)行識(shí)別,通過模擬鍵盤事件來完成操作用戶和虛擬裝配系統(tǒng)的交互。
[Abstract]:At present, virtual assembly systems usually rely on force feedback. As an interactive tool, the virtual assembly system uses intuitive gestures such as "grab" and "drag and drop" to complete the assembly of the product. However, when the assembly of fine parts model is encountered, the expected results are often not achieved. In order to solve this problem, this paper proposes to use Kinect as input to guide assembly process with Chinese speech instruction recognition, and designs and implements a bicycle virtual assembly system based on Chinese voice interaction, which verifies the feasibility of the method. The main contents of this paper are as follows: (1) Virtual assembly based on Chinese speech interaction involves modeling of virtual environment, rendering of virtual environment, recognition of Chinese speech, and so on. Therefore, in the design of virtual assembly system architecture, the communication mode of many kinds of software is considered, and the prototype system is designed and implemented by taking the bicycle virtual assembly as an example. (2) the design and simulation of virtual assembly environment. Using 3DS Max to complete the modeling of parts and scenes in the virtual assembly system, using Photoshop CS6 to complete the interactive menu design and texture image processing, and importing the scene model in 3Dvia Studio Pro to complete the design and rendering of the whole virtual assembly environment. (3) in order to reduce the operating error rate of users, a part assembly sequence planning based on recommendation is proposed. The assembly priority model of bicycle is defined by analyzing the physical connection relation, hierarchical relation and assembly constraint relation of the same level. Only when the higher priority part has completed the assembly simulation, the next priority part will be recommended as the part to be assembled. (4) in order to solve the problem of operator confirmation in multi-person environment, A method of Chinese speech instruction recognition based on Kinect is proposed, and the accuracy of this method is tested by experiments. The method uses Kinect device to capture bone tracking data of a number of people, and then determines the skeletal information of the user closest to Kinect in a certain range of areas in front of Kinect field of vision. The operator is determined by the coordinate information of the user's head and the sound source location function of the Kinect linear microphone array. The user's voice commands are captured and recognized in real time. The interaction between user and virtual assembly system is accomplished by simulating keyboard events.
