现场方位无人机航拍技法实验探究——以一起立交桥路道上案发现场方位照相为例

UAV Aerial Photography Techniques Experiment of Crime Scene: Taking a case on an Overpass as Example

通过模拟一起立交桥路道上案发现场方位的航拍实验,讨论无人机航拍案发现场方位的一般流程、操作步骤及方法,为将无人机航拍系统引入现勘工作并应用于城区道路案发现场方位图像信息的采集积累实践经验,有助于现场方位摄影思路的拓展,也有助于现场方位摄影传统方法的改良,实现案件现场方位照相中"最佳拍摄角度难以或无法寻找"难题的解决,拓展现场方位照相表现能力。

Through a simulation of aerial photography of a crime scene on an overpass, the article discusses the general process, operation steps and method, which can accumulate practical experience for applying UAV aerial photography system to crime scene investigation in urban area. It is helpful to develop the thinking of taking crime scene photography, to improve tradition ways of location photography, to solve the problem of finding the best shooting angle, and to perfect location photography skills.
