基于实景激光扫描技术的室内导航系统的建立

随着城市化进程的发展,人们在室内的时间越来越多,室内空间的应用价值也越来越高。在智慧城市的发展过程中,大量的室内空间需要数字化,室内空间数据的获取手段和数据应用需要进一步挖掘。本文利用三维实景激光扫描仪对北方工业大学浩学楼进行数据采集,创建了实景展示和实景导航,重点介绍了M3扫描车获取点云数据,并将点云数据进行拼接、去噪等处理,最后分析了点云数据的精度。由此可以得出实景激光扫描技术在建立室内导航系统中的可行性、高效性和准确性。     

Stability analysis on Jinjia dam hydropower project in Chongqing City

The stability analysis is one of the chief problems at hydropower stations. The Jinjia Hydropower Station is a significant project in Southwest China. The paper adopts the rigidity limited equilibrium theory and evaluated stability of the slope body, which will provide the evidences for further detail design.
