| Summary: | In recent years, Mobile Laser Scanning (MLS) systems have garnered increasing attention for their efficient and convenient data acquisition, finding widespread applications across various fields. However, most users typically select a single system that best suits their needs, with few attempts to utilize two independent MLS systems simultaneously. To explore this possibility, we selected two currently leading commercial MLS systems (Z+F FlexScan 22 and Leica BLK ARC) and developed an uncertainty analysis workflow to quantitatively evaluate their respective uncertainties. Following this, a trajectory-based fusion method was employed to merge point clouds from both systems. The experimental results demonstrate that our uncertainty-aware evaluation and fusion solution successfully decreased trajectory estimation drift and point cloud noise, offering a feasible solution for evaluation and fusion of simultaneous scanning with dual indoor MLS systems. |
