摘　　要：传统的案事件现场方位照录像和现场概貌照录像存在难以在现场附近找到合适的拍摄制高点、拍摄点视角有限和一些危险的现场勘查人员难以进入等问题。航拍无人机具备操控性能好、机动灵活、成像质量较高等特点,将无人机引入现场勘查工作中,可以很好地解决现场方位照录像和现场概貌照录像中存在的一些问题,极大地提高现场照录相工作的质量和效率。本文在介绍无人机的基本原理和操控方法的基础上,对无人机在案事件现场照录像的实际应用情况进行了总结,归纳了爆炸类大范围案事件、高坠类案事件和现场低洼类案事件三类无人机适用的典型应用场景,并结合典型案例介绍了无人机的具体操作方法和注意事项。最后,本文分析了采用无人机开展现场重点部位照相和现场重点细目照相的可行性,并对无人机未来在案事件现场勘查中的应用前景进行了展望。For the crime scenes,both azimuth and overview photographing/video-recording are required,yet the traditional manipulation is of limitations,e.g.,difficulty to find the suitable shooting height/spot around the crime scene,restriction of visual angles at the shooting spot and some dangerous scenes to prevent investigating photographers from entering.Unmanned aerial vehicle(UAV)brings opportunities and promise to overcome the above problems since it excels in good handling performance,fl exibility,wide range of environmental adaption and high image quality when it is fi xed of mancontrolling camera.Here,the introduction was at first conducted of UAV about its basic principle and manipulating methods,with the summarization being put through the actual applications where three suitable typical application scenarios were especially expatiated,the large-scale explosion scene,the high falling scene and the low-lying scene.Successively,the specific operation methods and precautions of UAV were illustrated in combination with the exampling cases of applications at typical crime scenes.Finally,an analysis was carried out on the possibility for UAV to photograph the key areas/subtlety of crime scene,with the applicable prospects of UAV being discussed in the future crime scene investigation.
