近景三维GIS技术用于刑侦现场虚拟再现的方法初探

三维建模的前端数据源是基于非量测相机地面获取而构建的特定场景的三维地理信息系统,在国内“三维GIS”应用领域还鲜见有报道,这一概念暂且定义为“近景三维GIS”。以刑事侦察工作区的案发现场为例,本文初步探讨了利用“近景三维GIS”技术快速构建三维模型来建立包含场景空间信息及其相关组成要素在内的刑侦现场三维GIS的可行方案。这一方案同样适用于如交通事故现场和其他需要三维模拟分析的现场。

刑侦现场勘查中的指纹提取

受到多种内外部因素的影响，刑事案件在我国仍时有发生，为尽早破案，恢复社会稳定，侦查人员应加大对案发现场的重视程度，科学利用指纹提取等先进科学技术，准确、全面地收集案发现场遗留下来的线索，确保侦查工作的顺利进行。基于此，本文以指纹提取在勘查过程的必要性为基础，结合指纹提取指令与准确性的因素，重点探究其改进方式。

The Development of Forensic Process Model for Criminal Investigation in Three Southern Border Provinces of Thailand

The purpose of this research is to study the process of forensic science execution in order to use crime investigation in three southern border provinces of Thailand, such as the study of problems and obstacles including the factors that affect forensic examination to use criminal investigation in three southern border provinces, offer the guidance in pattern development of forensic sciences examination in three southern border provinces with standard, and are able to use in criminal investigation effectively. Data were collected from all related agencies. The results of this research have showed that executive process of forensic science is used to investigate the crime in three southern border provinces that can be divided the operations into three main issues as following： crime scene examination, evidence testing, autopsy in case of crime scene, and factors which affect forensic work for using in criminal investigation in three southern border provinces of police practitioners. They should have the knowledge about forensic science, commitment, bravery, and cunning work.
