ABSTRACT
In order to make Beijing Bell and Drum Towers' Safety detection and structural stability evaluation, we carried out a three-dimensional laser surveying and mapping of Beijing Bell and Drum Towers. And based on three-dimensional laser point cloud data, carried out flat, vertical, cross-sectional construction mapping of the main architecture, texture mapping, city platform tower wall inclined, tilted of the floor, wall roughness and surface flatness measuring of City platform, deformation detection of large timber structure, skew measurement of stone railing and other comprehensive detection work. It provides a detailed basis for the stability evaluation of the main architecture structure. In practice, explore the ancient architecture integrated application safety Inspection items use three-dimensional laser scanning technology, to carry out deformation measurement, disease testing and Safety detection of technical methods and procedures. At the same time, it also provides a comprehensive and detailed data for the follow-up repair engineering design and current data retention.

Application of GPR Detection Technology in Beijing Bell and Drum Towers’ Safety Detection
ICGDA '21: Proceedings of the 2021 4th International Conference on Geoinformatics and Data AnalysisBeijing Bell and Drum Towers have been running for hundreds of years, there are many kinds of diseases after years of baptism. In order to protect it, it is necessary to make statistics and analysis of its structure on the basis of exploration and ...
Laser stripe model for sub-pixel peak detection in real-time 3D scanning
2016 IEEE International Conference on Systems, Man, and Cybernetics (SMC)Estimator algorithms rely on assumed laser stripe image profile to determine its peek with sub-pixel accuracy. They depend on light intensity readings around the peak and are susceptible to noise and saturation. Noise and stripe intensity models are ...
Using light polarization in laser scanning
We use polarization analysis in triangulation-based laser scanning to disambiguate the true laser stripe from spurious inter-reflections caused by holes and concavities on metal surfaces. Stripe candidates are discriminated by projecting linearly ...
