摘要
崖墓是四川地区具有地域特色的丧葬形式,数量众多,分布范围广泛。在分析墓葬间的空间分布关系方面,传统测量方法存在作业效率低、总体精度差等问题。因此,以新川创新科技园屈家山2号文物点为例,首先采用基于即时定位与地图构建技术的移动式三维激光扫描系统获取点云数据,再利用专业软件准确绘制墓葬分布图,并与测距仪测量结果进行对比分析。结果表明,移动式三维激光扫描系统可明显提高绘制崖墓分布图的作业效率,且满足测量精度要求,在考古领域中具有较好的应用前景。
As a funeral form with regional characteristics in Sichuan,cliff tombs are numerous and widely distributed.In the analysis of spatial distribution relationship between tombs,the traditional measurement methods have some problems,such as low efficiency and poor overall accuracy.Therefore,taking Qujiashan No.2 cultural relic site in Xinchuan Innovation and Technology Park as an example,we used the mobile 3D laser scanning system based on simultaneous localization and mapping(SLAM)technology to obtain point cloud data at first.And then,we used professional software to accurately draw the distribution map of tombs,and compared it with the measurement results of rangefinder.The result shows that the mobile 3D laser scanning system can significantly improve the mapping efficiency of cliff tomb distribution map,and meet the requirements of measurement accuracy,which has a good application prospect in archaeology.
