浅谈数码成像技术在现场勘查中的应用 李林青 [摘 要]为提高现场勘查工作的效率,数码成像技术已经被广泛地应用到了公安工作做中，例如视频监控、数码照相、数字摄像、数字监控技术，虽然它们在刑事案件的侦破及现场勘查中应用的时间并不长短不一,但它们所具有的独特性及发挥出的重要作用越来越为人们所注意和认识,特别是当办案人员在案件侦破过程中出现岔枝或久侦不破时,他们首先希望的是能够重临案发现场,但由于种种原因的存在,使得现场不易长久保存,所以如何解决这一难题是至关重要的,虽然有些刑事技术如:照相、录音、笔录……等具有记录、保留现场资料的作用，但是数码成像技术在现场勘查中的应用是传统的刑事科学技术所能替代的，而且随着科技的的进步，数码成像技术将会更加广泛的被应用于公安工作的各部分工作中。 [关键词]现场勘查；数码；监控；照相；刑事科学技术 Discussion on digital imaging technology in the field of exploration Abstract：In order to improve the work efficiency of field exploration, digital imaging technology has been widely applied to public security work, such as video surveillance, digital camera, digital camera, digital monitoring technology, although they are in the detection of criminal cases and crime scene investigation in the application of the time is not long, but they have unique and play the important role more and more peoples attention and recognition, especially when the investigators in the case of the detection process in bifurcated branches or long investigation is not broken, they hope to be able to return to the scene, but due to kinds of reasons, the site is difficult to store for a long time, so how to solve this problem is essential, although some criminal technology such as: photography, audio, transcript......Having recorded field data, retaining the role, but digital imaging technology in the exploration of the application of traditional criminal science and technology can replace, and along with the progress of science and technology, digital imaging technology will be more widely applied to each part of the work of public security work.
