【摘要】：增强现实(Augmented Reality,AR)技术,是在虚拟现实(Virtual Reality,VR)技术的基础上发展起来的新兴技术,使虚拟物体与真实场景完美融合,同时用户可通过人机交互技术与虚拟物体进行交流,使人们获得超越现实的感官体验。AR家具布置是指将增强现实技术应用于家居生活领域,通过在用户房间叠加3D虚拟家具模型,并实时对家居设备进行摆放操作,模拟真实的家居装修过程,从而实现在将家具未买到家里之前就看到在房间中摆放效果的目的,提高家居装修的沉浸感、交互性和实时性。随着移动设备计算处理能力的飞速发展,增强现实技术中图形处理运算需求可以逐步得到满足;同时,移动设备在便携性和人机交互方面明显具有优势。本文研究了基于AR技术的家居布置,实现了虚拟家具与真实场景相融合,主要内容包括市场调研、技术选定、核心算法优化及具体工程实现四个方面:首先,对增强现实技术的应用领域、研究背景、国内外发展现状及实现方法进行调研,研究如何将新兴的AR技术融入到家居布置中,使虚拟家居更为真实、易用。其次,详细阐述了基于AR技术的家具布置系统工程框架,以及选用的核心技术,如图像识别与跟踪技术、相机外参矩阵计算、三维重建技术与虚实融合技术。第三,提升设备对标识物识别的性能与人机交互的稳定性。本文基于方向信息对目前主流的图像识别与跟踪技术之一随机蕨算法进行改进,简称方向蕨(Oriented Ferns,OFerns),使分类器体积为原始大小的1/8至1/16,解决其无法在目前的移动设备或内存较低的计算机上使用;同时,结合了三维重建技术,在体验距离上较原始算法提高了13倍以上。最后,为了验证本文设想的可行性,设计并实现了一款基于AR技术的家具布置系统。经过分析数据和评测,该系统具有虚实融合、可自然人机交互以及可多平台运行的特点,具有良好的实际使用价值。
[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. This paper studies the home layout based on AR technology and realizes the fusion of virtual furniture and real scene. The main contents include market research, technology selection, core algorithm optimization and concrete engineering implementation. This paper investigates the application of augmented reality technology, research background, domestic and international development status and implementation methods, and studies how to integrate the emerging AR technology into the home layout to make virtual home more real and easy to use. Secondly, the frame of furniture layout system engineering based on AR technology is described in detail, and the selected core technologies, such as image recognition and tracking technology, camera external parameter matrix calculation, 3D reconstruction technology and virtual reality fusion technology, are discussed in detail. Third, improve the stability of the identification performance and man-machine interaction. In this paper, based on the direction information, the random fern algorithm, one of the most popular image recognition and tracking techniques, is improved. Oriented Ferns,OFerns, for short, makes the classifier one-eighth to one-sixth the size of its original size, solving the problem of not being able to use it on current mobile devices or low-memory computers; at the same time, it combines three-dimensional reconstruction techniques. Compared with the original algorithm, the experience distance is more than 13 times higher. Finally, in order to verify the feasibility of this paper, a furniture layout system based on AR technology is designed and implemented. Through analysis and evaluation, the system has the characteristics of virtual reality fusion, natural human-computer interaction and multi-platform operation, and has good practical value.
