【摘要】：傳統(tǒng)的照片因為展現(xiàn)形式簡單、內(nèi)容單薄,不能讓客戶充分了解相應(yīng)場景的三維空間結(jié)構(gòu)。隨著房地產(chǎn)、家裝等線上展示平臺的發(fā)展,使用三維模型結(jié)合全景圖片來重現(xiàn)室內(nèi)場景的方式受到越來越多人的推崇。但是,當(dāng)前國內(nèi)產(chǎn)品都只是簡單的全景圖片的切換,并不具有三維結(jié)構(gòu),用戶無法獲知空間信息。在這個背景下,本項目旨在將全景和模型進行結(jié)合,對室內(nèi)三維場景進行數(shù)據(jù)采集、處理和展示。本文主要研究室內(nèi)三維數(shù)據(jù)的采集和模型的拼接,設(shè)計并實現(xiàn)了基于IOS設(shè)備對室內(nèi)三維場景數(shù)據(jù)進行采集處理和管理的系統(tǒng)。本文設(shè)計并實現(xiàn)的室內(nèi)三維模型的數(shù)據(jù)采集處理系統(tǒng),包含項目管理、數(shù)據(jù)拍攝獲取、模型拼接三個子系統(tǒng)。其中,項目管理子系統(tǒng)負責(zé)在IOS應(yīng)用上對單個項目數(shù)據(jù)進行編輯處理和多個項目的展示、編輯。數(shù)據(jù)拍攝獲取子系統(tǒng)負責(zé)數(shù)據(jù)采集,IOS應(yīng)用通過連接拍攝設(shè)備的WI-FI控制拍攝設(shè)備轉(zhuǎn)動,并獲取拍攝到的點云數(shù)據(jù)和全景圖片數(shù)據(jù)。模型拼接子系統(tǒng)負責(zé)處理拍攝設(shè)備采集的原始3D點云,通過計算出兩次掃描的相對旋轉(zhuǎn)、平移信息,將多次不同的掃描數(shù)據(jù)放在同一坐標系中。該系統(tǒng)IOS應(yīng)用開發(fā)使用Objective-c語言和MVC框架,IOS應(yīng)用與拍攝設(shè)備間使用Socket進行通信,數(shù)據(jù)存儲使用CouchbaseDB,模型點云展示使用SceneKit,在I0S應(yīng)用與服務(wù)器間使用HTTP和HTTPS通信,底層的室內(nèi)三維模型的拼接使用C++實現(xiàn)。本文介紹了室內(nèi)三維模型的數(shù)據(jù)采集處理系統(tǒng)的項目背景、研究現(xiàn)狀、使用到的技術(shù)背景;而后對系統(tǒng)進行需求分析,完成對系統(tǒng)的整體架構(gòu)設(shè)計和各模塊的詳細設(shè)計;最后,對系統(tǒng)各模塊的實現(xiàn)細節(jié)進行描述,并展現(xiàn)項目的成果。室內(nèi)三維重建應(yīng)用廣泛,并開始走進大眾視野。本文對室內(nèi)三維模型的數(shù)據(jù)采集處理的研究,是對三維重建的實際應(yīng)用場景的一次探究。降低了室內(nèi)三維模型的數(shù)據(jù)采集的門檻,提高了三維重建的數(shù)據(jù)采集的自動化程度和采集效率。
[Abstract]:Because of its simple presentation and thin content, traditional photos can not fully understand the 3D spatial structure of the corresponding scene. With the development of real estate, home decoration and other online display platforms, the use of 3D models combined with panoramic images to reproduce indoor scenes has been praised by more and more people. However, the current domestic products are only simple panoramic image switching, do not have a three-dimensional structure, users can not get spatial information. Under this background, this project aims to combine panorama and model to collect, process and display the indoor 3D scene. This paper mainly studies the collection of indoor 3D data and the splicing of models, and designs and implements a system of collecting, processing and managing indoor 3D scene data based on IOS equipment. The data acquisition and processing system of indoor 3D model is designed and implemented in this paper, which includes three subsystems: project management, data shooting and acquisition, and model splicing. The project management subsystem is responsible for editing individual project data and displaying and editing multiple items in IOS application. The data capture subsystem is responsible for data acquisition iOS application controlling the rotation of the shooting equipment by connecting the WI-FI of the shooting equipment and acquiring the point cloud data and panoramic picture data. The model splicing subsystem is responsible for processing the original 3D point cloud collected by the shooting equipment. By calculating the relative rotation and translation information of the two scans, the different scanning data are placed in the same coordinate system. The IOS application of the system uses Objective-c language and MVC frame iOS application to communicate with shooting equipment, data storage uses Couchbase DBs, model point cloud display uses scene Kitt, and I0S application uses HTTP and HTTPS to communicate with server. The bottom floor of the interior three-dimensional model splicing using C to achieve. This paper introduces the background of the data acquisition and processing system of the indoor 3D model, the status quo of the research, the technical background used in the system, and then carries on the requirement analysis to the system, completes the overall architecture design and the detailed design of each module of the system; finally, The implementation details of each module of the system are described, and the results of the project are presented. Indoor three-dimensional reconstruction is widely used, and began to enter the public view. In this paper, the data acquisition and processing of indoor 3D model is an exploration of the practical application scene of 3D reconstruction. The threshold of data acquisition of indoor 3D model is reduced, and the automation degree and efficiency of 3D reconstruction data acquisition are improved.
