ITAI崩溃测试和研究日

22 July 2019

This year, Leica Geosystems once again sponsored the Institute of Traffic Accident Investigators’ Crash Test and Research Day at Bruntingthorpe Airfield and Proving Ground. Over 420 delegates attended, including collision and crime-scene investigators, fire and ambulance services, private investigators, insurers and salvage companies.

ITAI委员会成员检查员Richard Auty是大都会警察道路与运输警务司令部高级法医碰撞调查员，他领导了这一天。他说：“我对莱卡的支持感到非常高兴。”“没有他们，我们很难上演活动并进行如此广泛的重要测试。”

Mike Skicko, Leica Geosystems’ UK public safety lead for forensics and collision investigation, explained why Leica sponsors the event. “We’ve been working very closely with police forces across the UK for the past two years, moving from being simply a solutions provider to being the go-to source of advice and support for collision investigators. Events like this cement our relationships with individual crash investigators. These relationships help us understand each force’s individual working practices so we can offer best practice on surveying and validation, and recommend the best scene-to-screen workflow for them.”

做一个调查

验证测试的受控碰撞
A number of crash tests were conducted throughout the day which were impacted by a remotely controlled vehicle, at speeds ranging from 40-90 mph and with varying degrees of overlap. Using Leica Geosystems RTC360 scanner, each vehicle was scanned both pre and post collision, to measure metal deformation (which can help to establish the collision speed) and momentum exchange.

根据Inspector Auty的说法，“今年的测试更为广泛，我们花了几个月的时间进行计划，因为我们正在使用Leica Geosystems RTC360收集的数据来验证我们的某些流程。Collision investigation has traditionally been part of the Road Policing or Traffic Departments, the operations side of police forces, but we’ll soon be coming under the Forensic Science Regulator, which has required us to conduct extensive testing to demonstrate the science we use is always valid across the wide range of cases we deal with. The ITAI event enabled us to gather the ‘ground truth’ we need to validate the current processes and techniques we use and we will retain it to validate any new processes, techniques or software in the future.

“ Leica的RTC360扫描仪很小且轻巧 - 而且很快。对于碰撞调查人员而言，这确实很重要，因为我们需要尽快重新开放道路。”

演示区
我们设置了一个示范区，其中一辆经历了受控崩溃的汽车，在这里我们演示了许多Leica Geosystems解决方案，包括RTC360,BLK 360,BLK3D, plus theGS18TGNSS tilt receiver and the VivaTS16 Total Station. As always, the RTC360 was a big draw thanks to its versatility, small size/weight, and its speed of data capture.

Leica Geosystems技术专家Juan Madronal与Sussex警察局高级法医碰撞调查员Colin O’Neil一起工作，展示了我们的Aibot AX20无人机（无人机）。在碰撞视线上方提供空中图像。AIBOT AX20是农村或难以访问场景的理想选择，或者崩溃碎片散布在广泛的地方。

在软件解决方案帐篷中，我们自己的凯特（Kate）博士奇特·沃克（Kate Strange-Walker）和塞萨尔·阿尔梅达（CésarAlmeida）使用了我们的场景至屏幕工作流程Cyclone REGISTER 360and the LeicaIMS 360事件映射套件。克劳斯·里克（Klaus Rieke）还邀请了崩溃测试的调查人员来尝试登记点云（验证过程的重要组成部分，这是所有崩溃调查人员都需要遵守批准的过程所必需的ISO/IEC 17020到2020年10月1日）。

“大都会警察已经使用了莱卡的总站和全科医生已有25年了。亚博5分钟快三他们为我们提供了出色的服务 - 他们的支持确实是典范。他们迅速对任何问题做出反应，并在我们的行动不足或失控后能够提供替换设备。”

关键速度分析
Iain Took of West Midlands Police is seconded to the NPCC’s Forensic Collision Network, and has been helping to prepare for ISO/IEC17020. On the day, he invited delegates to use Leica’s Total Stations to see how accurately they could all measure the same road marks – and they came in within a very tight tolerance. In his own force, he uses the Leica ScanStation P20 and the new RTC360: “It’s very convenient to use, and produces good results,” he says of the RTC360. “We looked at competitor brands, but we stuck with Leica because they give us cracking customer support.”

当天的其他活动
In the afternoon, Leica delivered a manufacturer-agnostic lecture on “Laser-scanning best practice对于碰撞调查人员”。特别是，我们研究了良好的几何形状对一起注册扫描的重要性，涵盖了不同的城市，农村和半农村场景。其他研讨会包括NPCC弗朗西斯（Frances）高级资深人士的ISO验证的最新信息；UKAS的David Compton在ISO/IEC 17020，ILAC G19和法医科学监管机构的实践守则的碰撞调查中的认证戴维·康普顿（David Compton）；和别的。

还有几次车辆处理活动，包括关键曲线练习，不完整的车轮锁定练习以及对较低的Tyre压力处理的检查。车辆驾驶的机会包括萨里消防局的最新训练车辆和大型货车（感谢Cemex） - 都可以看到最新的安全系统，特别是对于行人和骑自行车的人。
