Innovation of the aero maintenance system based on augmented reality ( ar ) technology and eye tracking technology, which can give real-time instruction for maintenance, is vital for enhancing the accuracy of maintenance and reducing the cost of maintenance . in the paper, the study work include 3 sections, as following : firstly, deducing 3d registration algorithm based on markers, depicting the display and 3d display technologies of artificial matters, and realizing 3d registration function specifically; secondly, establishing an eye-movement measurement system based on the infrared television method, making use of the thoughts of ranks superimposition to withdraw the pupil center coordinates, and giving the thaught of recombining the position relation of purkinje spot to determine the eye sight direction primarily; finally, describing the basic theory of augmented reality maintenance guiding system in detail, and introducing the software function and hardware frame, which will provide the foundation for the further study of this system 本文的研究工作主要包括以下三個(gè)部分:首先,改進(jìn)了有標(biāo)志點(diǎn)的三維注冊(cè)算法,并具體實(shí)現(xiàn)了三維注冊(cè)功能,最后試驗(yàn)驗(yàn)證了注冊(cè)算法的正確性,為將來(lái)基于無(wú)標(biāo)志點(diǎn)的發(fā)動(dòng)機(jī)維修誘導(dǎo)系統(tǒng)的研究提供基礎(chǔ)和實(shí)踐經(jīng)驗(yàn);其次,描述了基于紅外電視法的視線跟蹤系統(tǒng)的基本原理,對(duì)眼動(dòng)信號(hào)處理技術(shù)做了初步的研究,即利用了行、列疊加的思想提取了瞳孔中心坐標(biāo)和普爾欽(purkinje)斑點(diǎn)的坐標(biāo),闡述了結(jié)合瞳孔中心與普爾欽(purkinje)斑點(diǎn)的位置關(guān)系進(jìn)行初步判定視線方向的方法;最后,詳細(xì)描述了所構(gòu)建的增強(qiáng)現(xiàn)實(shí)維修誘導(dǎo)系統(tǒng)的基本原理、軟硬件框架,為今后維修誘導(dǎo)系統(tǒng)的深入研制提供基礎(chǔ)。
