ITAI Crash Test and Research Day
2019年7月22日
今年，Leica Geosystems再次赞助了在Bruntingthorpe Airfield及其探测基地的交通事故研究所的崩溃测试和研究日。超过420名代表参加了会议，包括碰撞和犯罪现场调查员，消防和救护车服务，私人调查员，保险公司和救助公司。
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.”
Leica Geosystems英国法医和碰撞调查的公共安全负责人Mike Skicko解释了Leica为何赞助该活动。“在过去的两年中，我们一直在与英国各地的警察部队紧密合作，从简单的解决方案提供商转变为对碰撞调查人员的建议和支持的来源。像这样的事件巩固了我们与个人崩溃调查员的关系。这些关系有助于我们了解每个部队的个人工作实践，因此我们可以为测量和验证提供最佳实践，并为他们推荐最佳的场景到屏幕工作流程。”

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。
According to Inspector Auty, “The tests were more extensive this year, and we spent several months in the planning because we’re using the data we gathered with Leica Geosystems RTC360 to validate some of our processes. 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
We set up a demonstration zone featuring one of the cars which had undergone a controlled crash, and here we demonstrated a number of Leica Geosystems solutions including theRTC360， 这BLK 360， 这blk3d，加上GS18TGNSS倾斜接收器和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。
Working alongside Colin O’Neil, senior forensic collision investigator at Sussex Police, Juan Madronal, one of Leica Geosystems technical specialists, showcased our Aibot AX20 UAV (drone). Providing aerial imagery directly above the crash sight. The Aibot AX20 is ideal for rural or difficult to access scenes, or where crash debris has been scattered over a wide area.
In the software solutions tent, our own Dr Kate Strange-Walker and César Almeida demonstrated our scene-to-screen workflow using旋风寄存器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).
“The Met Police have been using Leica’s Total Stations and GPS for over 25 years now. They give us an excellent service – and their support has genuinely been exemplary. They respond quickly to any problems and have been able to provide replacement equipment when ours has been away or out of action.”

Critical speed analysis
伊恩（Iain）对西米德兰兹（West Midlands）警察局（West Midlands Police）借鉴了NPCC的法医碰撞网络，并一直在帮助为ISO/IEC17020做准备。在当天，他邀请代表使用Leica的总站，以了解他们可以衡量相同的道路标记的准确性 - 并且他们在bob apple非常紧张的容忍度中进来。他使用Leica ScanStation P20和新的RTC360：“使用非常方便，并产生良好的结果，”他谈到RTC360时说。“我们研究了竞争对手品牌，但我们坚持使用Leica，因为它们为我们提供了破坏的客户支持。”
Other activities on the day
下午，莱卡（Leicafor 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.
