應用智慧型手機快速建模測量之研究

科技日新月異使用智慧型手機建模可以在短時間內拍攝且透過App快速建模後可於網站上觀看建模或至電腦內後處理成點雲資料，而在室內戶外拍攝時，常會受到許多環境因素的影響，例如距離長短、角度不同、光線溫度、物件紋理等，皆有可能影響建模的成果及測量之精度，在做拍攝時因注意每張拍攝時的角度及站位，拍攝時的畫面應如何涵蓋，每一張影像透過SfM(運動恢復結構)得出原先的相機位置，都是造成資料誤差及建模的好壞來源。本研究探討應用智慧型手機建模於123D Catch及VisualSfM+Trimble RealWork 4.2，探討建模、測量的可能性，以及分析其成果之精度。探討於不同距離造成的影響、不同軟體間產生的問題、參考點應如何點選以及提升精度的方法、基礎的點雲補點該如何執行、若建模失敗應如何處理、此技術可以應用於何處。經本文實驗後提出一個合適的建模標準作業程序，對現階段的智慧型手機存在的系統性誤差以及軟體隨機誤差的辦法。因123D Catch屬於雲端建模，並無法從何而知其建模過程，所以本文把拍攝好的相片給VisualSfM+Trimble RealWork 4.2可以做出類似於離線版本的建模過程，其處理過後的資料供使用者自行更改，並比較後選出目前建模的走向應利用於何處做一個整合。

Application of smartphone modeling to shoot in a short time, Quickly model through the App modeling on the site to view the modeling or to the computer after the processing point cloud data, Indoor and outdoor shooting, Often affected by many environmental factors, Such as distance length, angle, light temperature, object texture and so on, May affect the results of modeling and measurement accuracy, when shooting, note the angle and position of each shot, Each image is transmitted through SfM (Structure from Motion), Resulting in data errors and modeling of good and bad sources. This study explores the use of smartphone modeling at 123D Catch and VisualSfM + Trimble RealWork 4.2, explore the possibility of modeling, measurement, and analyze the accuracy of its results. Explore the effects of different distances and the problems that arise from different software, reference point should be how to click and improve the accuracy of the method, the basis of the point cloud fill point how to implement, If modeling failure should be handled, Where this technique can be applied. This article describes the appropriate modeling Standard Operating Procedure,The systematic error of the smart phone at this stage and the software random error method.
