With the continuous development of the oblique photography technique, it has been used more and more widely in the field of geological disasters. It can quickly obtain the three-dimensional(3D) real scene model of dangerous mountainous areas under the premise of ensuring the safety of personnel while restoring the real geographic information as much as possible. However, geological disaster areas are often accompanied by many adverse factors such as cliffs and dense vegetation. Based on this, the paper introduced the flight line design of oblique photogrammetry, analyzed the multi-platform data fusion processing, studied the multi-period data dynamic evaluation technology and proposed the application methods of data acquisition, early warning, disaster assessment and decision management suitable for geological disaster identification through the analysis of actual cases, which will help geologists to plan and control geological work more scientifically and rationally, improve work efficiency and reduce the potential personnel safety hazards in the process of geological survey, to offer technical support to the application of oblique photogrammetry in geological disaster identification and decision making and provide the scientific basis for personal and property safety protection and later-stage geological disaster management in disaster areas.

为了改善城市实景模型边缘模糊,提出了一种曲率引导的结构化线面特征重构方法。根据曲率特征将网格分割为平面、可展凹、可展凸以及不可展曲面4类,在平面分割结果内提取平面,在可展凹和可展凸分割结果内提取直线,对过度弯曲的不可展区域进行保留,最终形成包含几何特征的复合网格模型。结果表明,结合曲率信息预先设置几何特征的潜在范围,使得结构化线面特征更可靠,同时保证城市实景中复杂的树结构不被错误地提取为平面。

针对并行式运动恢复结构(SfM)在局部场景合并时稳健性差的问题,提出一种摄影测量局部场景稳健合并的并行式SfM方法。对整个场景的影像关联图进行分块及扩展处理,得到相互重叠的子区块,并利用一种改进的增量式SfM方法生成局部场景重建结果。在局部场景合并时,首先利用局部场景的重叠关系构建子区块关联图,并以子区块三元组为单元,进行粗差剔除;然后,利用子区块三元组的代数性质,优化得到更符合几何一致性的子区块间的相对变换;最后,从上述结果中计算得到更准确的局部场景到统一坐标系下的尺度、旋转、平移变换。试验采用无人机影像,结果表明本文方法在局部场景合并时有更好的稳健性,而且SfM结果的精确度也要优于其他并行式方法和COLMAP,在摄影测量和实景三维重建中有较大的应用潜力。

红花具有活血通经、散瘀止痛的功效,是临床常用的活血化瘀类中药之一。迄今,红花中已分离并报道的化合物有210多种,包括醌式查尔酮类(红花黄色素和红色素)、黄酮类、亚精胺类、生物碱类、聚炔类、有机酸类等。红花黄色素作为红花主要的水溶性活性成分,常用水提法进行提取分离,而红色素常用碱提酸沉法进行提取。近年,天然深共熔溶剂作为一种绿色溶剂在红花的色素提取分离中呈现出较好的应用前景。该文针对红花的化学成分进行系统地归纳,并对红花中色素类成分的提取工艺进行分析,以期为进一步合理利用红花资源提供参考。
