【摘要】：增強(qiáng)現(xiàn)實(Augmented Reality,AR)技術(shù),是在虛擬現(xiàn)實(Virtual Reality,VR)技術(shù)的基礎(chǔ)上發(fā)展起來的新興技術(shù),使虛擬物體與真實場景完美融合,同時用戶可通過人機(jī)交互技術(shù)與虛擬物體進(jìn)行交流,使人們獲得超越現(xiàn)實的感官體驗。AR家具布置是指將增強(qiáng)現(xiàn)實技術(shù)應(yīng)用于家居生活領(lǐng)域,通過在用戶房間疊加3D虛擬家具模型,并實時對家居設(shè)備進(jìn)行擺放操作,模擬真實的家居裝修過程,從而實現(xiàn)在將家具未買到家里之前就看到在房間中擺放效果的目的,提高家居裝修的沉浸感、交互性和實時性。隨著移動設(shè)備計算處理能力的飛速發(fā)展,增強(qiáng)現(xiàn)實技術(shù)中圖形處理運算需求可以逐步得到滿足;同時,移動設(shè)備在便攜性和人機(jī)交互方面明顯具有優(yōu)勢。本文研究了基于AR技術(shù)的家居布置,實現(xiàn)了虛擬家具與真實場景相融合,主要內(nèi)容包括市場調(diào)研、技術(shù)選定、核心算法優(yōu)化及具體工程實現(xiàn)四個方面:首先,對增強(qiáng)現(xiàn)實技術(shù)的應(yīng)用領(lǐng)域、研究背景、國內(nèi)外發(fā)展現(xiàn)狀及實現(xiàn)方法進(jìn)行調(diào)研,研究如何將新興的AR技術(shù)融入到家居布置中,使虛擬家居更為真實、易用。其次,詳細(xì)闡述了基于AR技術(shù)的家具布置系統(tǒng)工程框架,以及選用的核心技術(shù),如圖像識別與跟蹤技術(shù)、相機(jī)外參矩陣計算、三維重建技術(shù)與虛實融合技術(shù)。第三,提升設(shè)備對標(biāo)識物識別的性能與人機(jī)交互的穩(wěn)定性。本文基于方向信息對目前主流的圖像識別與跟蹤技術(shù)之一隨機(jī)蕨算法進(jìn)行改進(jìn),簡稱方向蕨(Oriented Ferns,OFerns),使分類器體積為原始大小的1/8至1/16,解決其無法在目前的移動設(shè)備或內(nèi)存較低的計算機(jī)上使用;同時,結(jié)合了三維重建技術(shù),在體驗距離上較原始算法提高了13倍以上。最后,為了驗證本文設(shè)想的可行性,設(shè)計并實現(xiàn)了一款基于AR技術(shù)的家具布置系統(tǒng)。經(jīng)過分析數(shù)據(jù)和評測,該系統(tǒng)具有虛實融合、可自然人機(jī)交互以及可多平臺運行的特點,具有良好的實際使用價值。
[Abstract]:Augmented reality (Augmented Reality,AR) technology is a new technology developed on the basis of virtual reality (Virtual Reality,VR) technology, which makes virtual object and real scene perfect fusion, at the same time, users can communicate with virtual object through human-computer interaction technology. To make people obtain sensory experience beyond reality. AR furniture arrangement means that the augmented reality technology is applied to the field of household life. By adding 3D virtual furniture model in the user's room, the furniture can be placed and operated in real time. Simulation of the real process of home decoration, so as to achieve the purpose of seeing the effect in the room before the furniture is bought at home, and improve the immersion, interactivity and real-time of home decoration. With the rapid development of computing and processing ability of mobile devices, graphics processing requirements in augmented reality technology can be gradually satisfied. At the same time, mobile devices have obvious advantages in portability and human-computer interaction.
