非接觸式立體量測裝置之設計與製作
Non-Contact Three-Dimensional Measuring Device Design and Fabrication
摘要
本論文針對體積量測，提出一種低成本、高實用性、易操作的複合式量測儀器，主要是建築工程中經常使用到的距離、高度、面積、體積量測相關儀器做進一步的整合。有鑑於建築用儀器大多昂貴且功能單調，因此本論文系統結合雷射測距模組、絕對型編碼器與微電腦控制器，並利用Solid Works進行機構設計，製作出一種可量測距離、高度、並以非接觸的方式量測待測物體積的多功能建築量測儀器。本系統在微電腦控制器中加入三角函數的餘弦定理進行邊長度演算，經由實驗驗證，本量測可運用感測器取得邊長量測的相關係數，透過三角函數的餘弦定理進行物體邊常量測的功能，使其在微電腦控制器上實現非接觸體積量測功能，並符合Measurement System Analysis中GR&R量測分析法。

This study proposes aneconomical, practical, and easy-to-operate combined measuring deviceto measure volume. This device integrates measuring tools that are commonly employed in architectural engineeringfor gauging distance, height, area, and volume, and has an error rate of less than 1% in volume measuring. Because most architectural devices are expensive and lack multiple functions, this study endeavors to integrate a laser rangefinder,absolute encoder, andmicrocomputer controller.This study also conducted mechanical design usingSolidWorks software for creating a multi-functional architectural device that can perform non-contact measurements of distance, height, and area. Regarding the microcomputer controller, the law of cosines in trigonometric functions was adopted to calculate side lengths. The experimental results verified that this device can identify the correlation coefficients of side-length measurements by usingsensors and calculating the side length of an object according to the law of cosines.Consequently, the study device achieved non-contact volume measurement usinga microcomputer controller, and the resultsconformed to the gauge repeatability and reproducibility (GR&R) method in measurement system analysis.
