进行文档和调查交通事件的外部条件起着重要作用

在交通事故中，如犯罪或消防/纵火场景等其他事件一样，警察机构进行视觉检查并保留证据。证据为分析和重建事件的过程提供了基础。通常，事故/事件发生后必须立即进行文档和调查。在现场工作的警察有时需要在艰难的外部条件下进行碰撞文档 - 在不利的天气条件下，例如雪，雨，雾等。在范围内数百米的大规模事件中，该文件可能是冗长的，有时需要需要同时完成：白天和晚上。每个调查都是不同的。在许多情况下，响应者会受到压力，事件环境以及受害者和证人的情绪状态等因素的负担。快速记录，清理并重新开放交通事故现场，这也意味着对所有参与人员的巨大压力。

不应低估交通事故中的特征和各种痕迹

需要记录的交通事故的痕迹不仅仅是直接在肉体上可见的机械镜痕迹，而且涉及事故的车辆的底盘。它们还包括在路面上剩下的各种轨迹。这些是事故重建和分析的重要指标。事故或碰撞所涉及的车辆通过滚动，制动，锁定，漂移或打滑创造了轨道和标记。此外，可能存在不同类型的划痕，例如，由倾覆的单轨车辆的接地接触引起的：磨碎的痕迹，干燥标记或玻璃，灯或其他破碎部件的碎片。换句话说，需要记录各种迹线和指标。精确测定道路上距离轨道的几何形状，例如标记打滑标记长度的点的确定通常仅在文档直接现场期间才有可能。

The role of comprehensive documentation in accident reconstruction

The result of traffic event documentation and evidence gathering must be objective and precise and include the detected traces, the condition of involved vehicles and possibly injured persons, and the spatial relationships of all objects, traces and surroundings of the accident. The secured evidence is crucial for the correct reconstruction of the event. The evidence determines the probability of valid conclusions regarding the traffic parameters: before, during and after the collision. The material has a significant influence on the determination of the accident course and causes.

The problem: Immense challenges on-scene. The solution: Leica TS10 total station and eSURV forensic mapping software.

警察在记录事故时必须考虑的上述因素集可能会影响对发生的事情的正确解释。关于视觉检查，捕获事件细节的及时性的挑战，考虑到轨道的规格，调查的场景的大小，天气条件，相关人员等是巨大的。然而，警察当局需要直接在现场收集可靠的证据，以便在以后的阶段进行进一步调查。

CYBID, a Polish company specialized in the engineering of forensic mapping software and partner of Hexagon and Leica Geosystems, has developed a unique solution for traffic accidents documentation.

Leica-CYBID's solution is a complete system consisting of hardware and software tailored to the need for proper and comprehensive road accidents documentation. The system provides effective and efficient support for all emergency teams working on the incident scene, especially during the initial visual accident inspection and documentation, and for the analysis and reconstruction of the incident later on. The Leica-CYBID system consists of various software applications (eSURV, PLAN, V-SIM, PHOTORECT) and a Leica FlexLine TS10 total station.

The Leica TS10, a high-end manual total station, is used for on-site accident mapping. The total station has an extended range of up to 10 km, making it suitable for documenting minor as well as major, long-range incidents. Due to its robustness, the TS10 can operate in temperatures ranging from -20 to +50°C. The Leica TS10 has an IP rating of 66, which means the device is strongly water and dust protected. The backlit screen and keypad, laser pointer, large 5" colour touch screen display allows for comfortable operation in different conditions and situations (day-night, working with gloves, etc.), and make the device an excellent tool for data collection of a traffic event.
To meet the demand for fast measurement of an accident site, the TS10 has been combined with CYBID's forensic mapping software eSURV. eSURV was developed and optimized specially for on-site measurement purposes. The workflow is simple: the data collected with the Leica total station on-site is analyzed and processed by the eSURV software, which creates a 2D drawing/a sketch also on-site.

The operation of the eSURV software is intuitive and minimizes the risk of human error. It corresponds with the current standard accident documentation methodology of the Polish Police. Even though the Leica TS10 total station was designed for geodetic and surveying usage, combined with the CYBID eSURV software, makes it easy for a trained law enforcement officer to document a traffic accident on-site without specialized surveying know-how.

除ESURV应用程序外，还有以下软件模块：

• Cybid Plan设计用于创建情境图/草图和3D可视化。它包含用于绘制道路和十字路口的模块，包括垂直和水平标记在内的图书馆，车辆和其他道路使用者的轮廓（包括人身伤害的身体位置），全球和本地参考系统，层次，层次，可视化天气条件，支持WMS（正射图），用于尺寸，缩放，位图的导入（例如照片，大地测量基础）的工具，车辆数据库，导入点云和3D模型的可能性。

• CYBID V-SIM——用于创建模拟交易ffic accident scenarios and vehicle collisions. The V-SIM program imports the sketches created in the PLAN program. V-SIM allows the analysis of the course and consequences of vehicles' collisions with each other, with other road users and with terrain obstacles. V-SIM has a built-in force transmission and impulse collision model and a driver's model for simulating the driver's behaviour, including the possibility of simulating driver’s failures and damage to the vehicle. In addition, V-SIM has a technical database of vehicle models and a video recording function. V-SIM also allows the visualization of different weather conditions. In this software module, the observer (witness) figure can be placed at any location on the scene. Same for the driver and the passenger of the vehicle.
  
  V-SIM is widely used by the experts of the Police forensic laboratories and accident experts and the experts appointed by the courts (expert witnesses).
  

• CYBID PHOTORECT - developed for the photogrammetric image transformation. It enables the conversion of photographs into metric ortho plans. PHOTORECT integrates the photographic documentation into a situational sketch. Photogrammetrically transformed images can be used, e.g. as a carrier of information about tracks or traces on the road surface, the geometry of the location and at the same time as an indication of geolocation of elements/details of objects (evidence).
  The Leica-CYBID system is currently being introduced to the Polish Police throughout the country as a standard tool for accident documentation. The system delivers reliable and fast documentation of a traffic incident and its location regardless of external conditions.

The Leica TS10 and CYBID eSURV solution will make it possible for Polish Police officers to provide digital documentation of an traffic incident to crash and accident experts or courts for analysis, investigation, and reconstruction purposes.
