摘要

室內拓撲是多數室內適地性服務的基礎，完整的室內網路包括「樓層平面路徑」和「非平面路徑」兩種，後者如樓梯、電梯、手扶梯、坡道等。目前多數研究僅探討樓層平面路徑，i-GIT演算法是少數考慮非平面路徑的研究之一。然而，該演算法再產製樓梯路徑的部分僅適用於樓梯特定的建模參數，這些建模的限制大為侷限演算法的適用性。本研究基於i-GIT的室內拓樸產製架構，重新提出一套樓梯路徑產製的演算法。測試結果顯示，改良後的演算法能適用樓梯四種常見建模參數的12種組合，大幅提昇演算法的適用性。

The indoor topology is the foundation of most indoor location-based services. A complete indoor network includes ＂floor-level paths＂ and ＂non-level paths＂, such as stairs, elevators, escalators, ramps, etc. Unlike those studies that merely discussedthe generation of floor-level paths. i-GIT algorithm is one of the few studies considering both floor-level paths and non-level paths. However, the part of i-GIT algorithm that produces ＂Stair-Flight paths＂ only applies to those stair models under specific modeling parameters. These limitations tremendously restrain the applicability of the algorithm. Based on the same framework of indoor topology adopted by i-GIT algorithm, this study proposes a novel perspective algorithm for producing ＂Stair-Flight paths＂. The test results show that the revised algorithm can be applied to 12 combinations of modeling parameters of the stairs commonly used in most BIM software, which greatly broadens the applicability of i-GIT algorithm.
