为什么南威尔士警方正在使用Leica Geosystems BLK360用于激光扫描主要犯罪场景

The journey to buying a forensic laser-scanner

Russell Gardner是南威尔士州警察总部的联合科学调查单位的主要法医成像官，也为Gwent警方提供服务。该力一直在犯罪场景中使用手动测量技术和传统视频/摄影，但可以看到激光扫描可以带来的好处。“因此，对于一些主要案件，我们支付了外部服务 - 但这永远不会成为一个长期解决方案，”拉斯解释道。

“The BLK360 has worked well in our crime-scene investigations.” Russ Gardner, South Wales Police

长期场景捕获的好处

根据卢卡德纳的说法：“我们的使用系统有助于我们避免扰乱证据，我们可以在删除或处理任何事情之前永久捕捉整个场景。然后我们可以随时返回数据，甚至几年后，看看床的高度或见证人的角度。这真的很重要，因为当你在现场时，你不能知道几个月可能会在线上提出的问题。

作为法医成像专家，我们越来越多地对案件的结果有所作为，这也可能意味着对受害者或亲人的积极差异。

Using scan data can be important. We’re there at the very start of the case, gathering the evidence, and then again at the end when we present and interpret it in court. It’s a privilege to be involved in the whole journey, rather than just part of it.”

Scenario 1 – A buried victim

一个失踪的人变成了一个谋杀案件时body was found in a makeshift grave. Russ’ team scanned the burial area both before and after the body was removed, unsure what the data might offer but wanting to capture the best possible evidence as fully as they could.

包括法医考古学家在内的专家能够推断坟墓是如何挖掘的，并且在嫌疑人在挖掘并挖土时犯罪的地方。

The scan data was key in producing a very accurate visual record of the grave shape and structure, which is often difficult to see from 2D scaled drawings, photographs and plot diagrams.

法医考古学家说,扫描工作very well on this case and it does a great job of recording the scene to scale with relative ease, speed and most importantly to me, with no intrusion to the grave or what it contains. The videos you produced of the fly through were exceptional and really assisted in the presentation of the evidence.’

Senior Investigating officer DI Andy Miles said, “As the senior Investigating officer in this case I would have attended at the scene to view the landscape and deposition site for myself. Where this technology has a significant impact is for the benefit of others. The jury at the subsequent trial-obviously they would not have the benefit of being there themselves, the trial would have been many months later. I have no doubt that showing this emotive footage within the courtroom setting to the jury and the defendant has had the knock on effect of the defendant offering a guilty plea. Technology such as this cannot be underestimated in such cases”.

方案2 - 通过刺伤的车载谋杀

CCTV英尺长在一辆停放在房子外的车辆晚上晚上刺伤了。然而，很暗示很难解释镜头。所以第二天，Russ'团队使用该系统创建了“鸟瞰”飞行的场景，使车辆与CCTV相机有关，其视图范围。

虽然嫌疑人被其他方式所逮捕，但扫描数据提供了重要的确认和对案件中所有有关的地点和定向的理解，特别是陪审团。被定罪导致。
