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 council member Inspector Richard Auty, senior forensic collision investigator at the Metropolitan Police’s Road & Transport Policing Command, took the lead in arranging the day. “I’m very pleased about Leica’s support,” he said. “Without them, it would be much harder for us to stage the event and conduct such a wide range of important tests.”

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

Controlled collisions for validation testing
全天进行了许多碰撞测试，这些测试受到远程控制的车辆的影响，速度为40-90 mph，重叠程度不同。使用Leica Geosystems RTC360扫描仪，对每辆车进行碰撞前和碰撞后扫描，以测量金属变形（可以帮助建立碰撞速度）和动量交换。

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’s RTC360 scanner is small and lightweight – and it’s fast. For collision investigators, this is really important because we’re needing to re-open the roads as quickly as possible.”

Demo zones
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总站。与往常一样，RTC360由于其多功能性，尺寸/重量及其数据捕获速度，这是一个很大的吸引力。

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。

In the software solutions tent, our own Dr Kate Strange-Walker and César Almeida demonstrated our scene-to-screen workflow usingCyclone REGISTER 360和莉卡IMS 360incident mapping suite. Klaus Rieke also invited crash-test investigators to come and try their hand at registering point clouds (an important part of the validation process which will be required for all crash investigators as they head towards compliance withISO/IEC 17020by 1 October 2020).

“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。bob apple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时能够提供替换设备。”

Critical speed analysis
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 practicefor collision investigators”. In particular, we looked at the importance of good geometry for registering scans together, covering different urban, rural, and semi-rural scenarios. Other seminars included an update on ISO validation from Frances Senior of the NPCC; David Compton of UKAS on accreditation in collision investigation for ISO/IEC 17020, ILAC G19 and the Forensic Science Regulator's Code of Practice; and others.

There were also several vehicle-handling events, including a critical-curve exercise, an incomplete wheel lockup exercise, and an examination of low tyre-pressure handling. Vehicle-driving opportunities included Surrey Fire and Rescue’s newest training vehicle and large goods vehicles (thanks to Cemex) – both with a view to the latest safety systems, particularly for pedestrians and cyclists.
