為了更合理地描述地面雷射掃描儀系統性誤差，本研究提出自率定法結合個別組件校正的混合模式校正理論，共採用FARO S350、Trimble SX10與RIEGL VZ-400進行測試。根據t-test（95％信心區間）結果，使用系統性誤差改正參數的確能有效描述儀器系統性誤差模式，其中常數項與線性項改正參數已足以描述本研究三款掃描儀的系統性誤差模式，而帶入個別組件校正得到的參數更能達到約制的效果，呈現本研究提出之理論具有更謹慎地進行地面雷射掃描儀校正與評估系統性誤差分析的潛力。

To describe the systematic error of the Terrestrial Laser Scanners (TLS) more reasonably, based on the self-calibration method, a hybrid calibration theory that combines self-calibration and individual component calibration is proposed. In this study, FARO S350, Trimble SX10 and RIEGL VZ-400 were used to test at the National Land Surveying Center (NLSC). According to the results of t-test (in the 95% confidence interval), using systematic error calibration parameters can effectively simulate the TLS systemic error model. The results also show that the constant and linear calibration parameters are sufficient to describe the systematic errors of the three scanners used in this study, and the calibration parameters obtained from the individual component calibration can achieve a reduced effect. These show that the theory proposed in this study have the potential for more careful analysis of TLS calibration and evaluation of systematic errors.
