地板革上灰尘足迹的提取一直存在瓶颈,用传统的方法很难达到理想的效果。全波段CCD物证照相系统作为一项新技术在刑事科学技术领域应用的较好。通过在实际案例中的研究,发现全波段CCD物证照相系统对地板革上灰尘足迹的提取有了新的突破,在波长254nm的光谱下,利用紫外光照射,灰尘足迹显现效果最佳,既能有效的将地板革表面的背景杂色去掉,又能保持检材的完好。
There is always a bottleneck in extracting the dust footprint on the floor leather, which is difficult to achieve with the traditional methods. Full-band CCD photographic evidence system as a new technology in the field of criminal science and technology is better. Through the research in the actual cases, it is found that the full-band CCD photographic evidence system has made a new breakthrough in the extraction of the dust footprint on the floor leather. Under the wavelength of 254 nm, the dust footprint shows the best effect by using UV light, Effectively remove the mottled surface of the floor leather surface, but also to maintain the intact samples.
