摘　　要：案事件的调查中,常常需要专业人员出具书面的报告,对视频记载的事件过程进行描述和解释。实际案件中,视频内容的分析报告多采用时间顺序,以语言描述为主。本文提出视频内容解析的概念,综合运用图像处理、图像测量、现场实验等技术方法,对视频中人、车、物等状态及其相互关系进行定性和定量的分析。解析结果以文字与图表相结合的形式呈现,可以更清晰完整地表述视频中反映的事件过程,已在多起重特大案事件的现场视频分析中应用。对于持续时间较长、关键目标动作较复杂的案事件形成视频解析报告,有助于对事件过程的还原,提高了视频证据的证明能力。Objective The video-investigating professionals have responsibility to make due written reports on describing and interpreting the video-recorded event sequence.In practice,such reports are usually organized with text of words by chronological order.Here,a comprehensive method was provided to bring out the report with not only text but diagram as well.Methods The concept was at-fi rst proposed on the evidential video to be interpreted and analyzed.In completion of qualitative and quantitative analysis into the video-recorded people,vehicles and objects about their status and mutual relations,the approaches were comprehensively conducted through image processing and measurement,fi eld experimental simulation plus other technical choices.Results With presentation of the analytical results in the form of a combination of words,pictures and charts,the clearer and more complete description was made of the event process refl ected by the video from crime scene.The method described here has already been applied into the video analysis of serious and extremelybad cases.Conclusions For cases of long duration or complex actions performed with key targets,the comprehensive report comprised of both written words and diagram is helpful to recover facts and improve the proof ability of the evidential video.
