近年来，无人机产业发展迅速，随着制造成本的降低和技术的不断更新，体积小、重量轻、操作简便的微型无人机开始在市场涌现，无人机逐渐从军用市场走向商用。无人机可作为操作平台搭载不同的设备，具备侦查攻击、影像传输、物品投放、现场干预等功能，目前已广泛应用于公共安全、事故救援、森林防火、地质勘探、空中测绘、环境保护等领域。无人机航拍技术是以无人机作为搭载平台，通过专用照相机、摄像机以及视频无线传输技术从不同高度和角度俯瞰拍摄的方式获取图像和视频信息的技术。通过该技术可直观、快捷地获取案件现场的全景图像，解决大范围或大面积现场、特殊区域（海上、山区）发生的案事件或事故现场、道路交通事故及铁路事故现场、高层建筑火灾现场的全景拍照及快速取证问题。本文从试用情况和实际案例两方面介绍了无人机航拍技术在犯罪现场勘查方面的应用现状，对该技术在犯罪现场勘查领域的应用前景进行了展望。%With the continuous decline of production cost and improvement of performance, the unmanned aerial vehicle (UAV) industry has developed rapidly from high-end commercial use to mass market in recent years. UAV has the advantages of small size, light weight and easy operation so that it can be deployed to make reconnaissance and/or attack, photograph and transmit, deliver goods and conduct scene intervention. Until present, UAV has been widely used in public safety, accident rescue, forest fire prevention, geologic exploration, aerial photography, environmental protection and others. UAV aerial photography is to take photos of the ground and objects from different heights and/or angles by the UAV equipped with high-definition camera plus video and wireless video transmission device, being categorized into the low altitude photography that is permitted to carry out at a height less than aviation control. This paper explicates the on-going application of UAV aerial photography in crime scene investigation and prospects its development trend.
