摘要
针对馆藏铜鼓本体记录上的不足,将多基线近景摄影测量技术应用于馆藏铜鼓数字化及铜鼓保护领域.采用多基线交向摄影方式获取大重叠度的序列影像,通过多基线立体匹配、多光束交会和区域网平差等方法实现特征点匹配和多光束立体定位,提高铜鼓表面点云数据的可靠性与精度.实验表明,该方法操作简便、快速高效,满足馆藏文物精细建模的要求.
On account of deficiency in bronze drum collections,multiple baseline close-range photogrammetric technology is applied in the field of bronze drum digitalization and protection.Multiple baseline to cross the way of photography is adopted to get sequence images with large overlap.Characteristic point matching and multiple beam stereo positioning are realized by using multiple baseline stereo matching,multiple beam intersection and block adjustment.The reliability and accuracy of surface point cloud data are improved.Experiments show that this method is simple but efficient,and it meets the requirements of fine modeling for cultural relics collections.
