文物建筑的激光信息采集方法

Laser information collection method of cultural relic buildings

为了解决传统全站手持测距仪数据采集方法存在的检测精度低以及稳定性差的弊端,提出基于三维激光扫描技术的文物建筑信息采集方法,分析了三维激光扫描的工作原理,基于该原理分别分析了三维激光扫描技术实现文物建筑体扫描测绘、文物建筑彩绘扫描测绘、文物建筑彩绘拍摄以及文物建筑数据配准的过程,其中对文物建筑点云数据数据配准过程中,基于不同规模的场景,选择合理的配准方法。依据采集到的文物建筑信息,基于点云剖面的方式实现文物建筑的手工测绘。实验结果说明,所提方法的文物建筑信息采集精度高,获取的云数据质量更为平稳,并且具有较高的数据配准精度和绘制精度。

In order to solve the traditional total station with telemeter data acquisition method of the disadvantages of low detecting precision and poor stability,based on 3 d laser scanning technology of cultural relic building information collection methods,the working principle of 3 d laser scanning is analyzed,respectively.Based on this principle, the process of 3 D laser scanning technology to realize the scanning and mapping of cultural relics and buildings, the scanning and mapping of cultural relics and buildings, the photographing of cultural relics and buildings and the data registration of cultural relics and buildings are analyzed.In the process of point cloud data registration of cultural relic buildings, a reasonable registration method is selected based on different scale scenes. According to the information of the cultural relics collected,the manual mapping of cultural relics is realized based on the method of point cloud profile.The experimental results indicate that the proposed method of information acquisition of high precision,a historical building for cloud data quality is more stable,and have higher accuracy and mapping data registration accuracy.
