多源数据融合：老旧小区改造中测量技术的对比与应用
Multi-Source Data Fusion: Comparison and Application of Measurement Technologies in the Renovation of Old Residential Communities
摘要: 为解决老旧小区改造中测量效率低、数据精度不足的行业痛点，本文以武汉市楚材社区为研究对象，构建涵盖激光测距仪、手持激光扫描仪、架站式三维激光扫描仪及无人机航测的多源测量技术评价体系，并通过实测数据展开分析对比。结果显示：毫米级精度的架站式扫描仪在建筑结构分析中具有显著优势(皮尔逊相关系数R = 0.98)，但单站覆盖范围受限；无人机航测可实现1:2000比例尺地形建模，却受限于低空地面采样距离；手持设备在室内狭窄空间测量中效率提升300%，但存在2 cm级系统性误差。进一步研究表明，采用多源数据融合策略可将总体测量误差降低约47%，大幅提升数据完整性与改造适配性。研究成果为老旧小区改造中测绘方案的优化提供了坚实的理论支撑与可靠的实证依据。
Abstract: To address the critical challenges of low measurement efficiency and inadequate data precision in the renovation of old residential communities, this paper takes the Chucai Community in Wuhan City as the core research object, and constructs a multi-source measurement technology evaluation system covering laser rangefinders, handheld laser scanners, stationary 3D laser scanners, and unmanned aerial vehicle aerial surveying. The analysis and comparison are carried out through the collected field data. The results show that the stationary scanner with millimeter-level accuracy has a significant advantage in building structure analysis (the pearson correlation coefficient has a value of 0.98), but its single-station coverage is relatively limited; unmanned aerial vehicle aerial surveying can achieve 1:2000 scale terrain modeling, but is limited by the practical low-altitude ground sampling distance; handheld devices increase the measurement efficiency by 300% in indoor narrow spaces, but have a systematic error of 2 cm. Further research shows that the adoption of reasonable multi-source data fusion strategies can reduce the overall measurement error by approximately 47%, significantly improving data integrity and renovation adaptability. The research results provide a solid theoretical support and reliable empirical basis for the effective optimization of mapping schemes in the renovation of old residential areas.
