【摘要】：高坠死亡案件的现场分为坠落起点、坠落轨迹和坠落终点,公安机关在勘查现场过程中需大量测量距离数据;随着手持式激光测距仪逐渐在公安机关刑事技术部门装备,为探讨该仪器在高坠案件现场勘查中的应用价值及使用技巧,回顾并总结了近年来在高坠类案件勘查中该仪器的使用经验。结果表明,与传统的测距工具相比,手持式激光测距仪具有重量轻、体积小、操作简便,测距非接触、测速快、测量精度高等优点,在高坠案件现场勘查中发挥重要作用,值得推广,但由于现场勘查工作的特殊性,在使用中要注意测量的方法及技巧,并探讨研制公安现场勘查专用测距仪的可行性。
[Abstract]:The scene of a high fall death case is divided into the starting point of fall, the track of falling and the end of fall. The public security organs need to measure a large number of distance data in the course of investigating the scene. As the hand-held laser rangefinder is gradually equipped in the criminal technical department of the public security organ, In order to discuss the application value and skill of the instrument in the field survey of high drop cases, the application experience of the instrument in the field investigation of high drop cases in recent years is reviewed and summarized. The results show that compared with the traditional ranging tools, The hand-held laser rangefinder has the advantages of light weight, small volume, simple operation, non-contact ranging, fast speed measurement and high measurement precision. It plays an important role in the field investigation of high drop cases and is worth popularizing. However, due to the particularity of the field survey work, attention should be paid to the methods and techniques of measurement in use, and the feasibility of developing a special range finder for public security site survey should be discussed.
