| Project overview Tianjin Railway Transportation "Rapid Investigation and Disposal System of Road Traffic Accident Site Based on Three-dimensional Scaleless Photogrammetry" is a traffic accident scene rapid disposal system developed by Tianjin Railway Transportation Co., Ltd. in strict accordance with the relevant regulations of the Ministry of Public Security on road traffic accident disposal, and in combination with the theoretical algorithm of computer image intelligent recognition. In order to quickly clean up and remove the scene of traffic accident and restore the road traffic as quickly as possible after taking several digital photographs at the scene of traffic accident, the digital photos taken at the scene of the accident can be identified and processed by a large number of intelligent operations through the system software on the spot, so as to quickly and accurately acquire the needs of investigation and location at the scene of the accident. All the data needed need no manual measurement. Accident traffic police can quickly produce the scene scene scene record map of road traffic accident and the scene scale map of road traffic accident, which is convenient for accident parties to sign and approve at the scene. At the same time, the system also has the scene investigation record, inquiry record and interrogation pen. In order to facilitate the identification and analysis of accident liability, the system can also be equipped with three-dimensional simulation and analysis function of road traffic accident scene. Project qualification 1. In 2017, Tianjin Railway Communications Corporation and the Ministry of Public Security jointly drafted and formulated the industry standard of GA/T1381-2018 "General Technical Conditions for Drawing Road Traffic Accident Site Maps", leading the frontier development direction of the project field. 2. Participate in the scientific research task of the National Plan of Action for Road Traffic Safety Science and Technology organized by the Ministry of Public Security, the Ministry of Science and Technology and the Ministry of Transportation in 2010, which is the seventh topic of "Road Traffic Safety Law Enforcement Technology and Wide-ranging Application"; 3、The project has been listed in the "Guidance Plan for Scientific and Technological Achievements of Public Security" of the Ministry of Public Security in 2009 and designated to be popularized and applied in the traffic police departments of the whole country. 4. Product items are strictly identified by the Road Traffic Safety Product Testing Center of the Ministry of Public Security, which fully conforms to the relevant countries. 5. The photogrammetric accuracy of the system has been confirmed by the strict test of Tianjin Institute of Metrology Supervision and Inspection 6. It has two major patent technological advantages originated exclusively by the whole country: 7. Winning "Tianjin Municipal Government Science and Technology Progress Award" and "Tianjin Public Security Bureau Science and Technology Achievement First Prize" Application Customer 1. The product project has won nearly 30 bids for government procurement bidding projects at the level of National Traffic Police Corps in many provinces. It has a large number of traffic police customer application groups: Traffic Police Corps Tianjin Public Security Traffic Administration in 2007 Traffic Police Corps Traffic Police Corps of Qinghai Public Security Bureau in 2012 3. The product project has won nearly 30 bids for government procurement bidding projects at the level of National Traffic Police Corps in many provinces. It has a large number of traffic police customer application groups: Traffic Police Corps Chongqing Public Security Traffic Administration in 2014 Traffic police detachment High Speed Traffic Police Detachment of Hunan Public Security Traffic Administration Traffic police detachment Yinchuan Traffic Police Detachment of Ningxia Hui Autonomous Region Traffic police detachment Traffic Police Detachment of Jingdezhen City, Jiangxi Province
Technical characteristics 1. The system is simple and practical, especially suitable for front-line police without any experience in computer operation. 2. Fully automatic digital three-dimensional photogrammetry of traffic accident scene has been realized. No calibration objects need to be placed on the scene, only a few pictures of the accident scene need to be taken simply and quickly, then the scene of traffic accident can be quickly removed. After that, the system software carries out a large number of intelligent operations to identify and process the scene photos, which can be accurate. Reliably generate all the labeled data needed for site investigation and positioning without manual measurement, which reduces the hidden danger of secondary accidents and greatly improves the efficiency of accident site disposal. 3. It can automatically and intelligently stitch the photographs taken at the accident scene to form a complete accident scene map, which is convenient for dealing with the complex accident scene quickly. 4. It can automatically and accurately identify and locate reference points, reference lines, vehicles and other elements in traffic accident scene photos. It is more intelligent and easy to quickly generate traffic accident scene map. 5. Random and intuitive distance data can be labeled in the digital photos taken at the accident scene. The system supports printing of "Road Traffic Accident Scene Record Map". 6. The road graphics data can be automatically loaded into the traffic accident scene by GPS satellite positioning without manual road plotting. 7. The "road intelligent pencil" drawing function initiated in China makes it possible for traffic policemen to draw a sketch of traffic accident scene easily and quickly on the computer. It is as simple and intuitive as the drawing habit of traffic policemen on paper, and has a high degree of intelligence. It is especially suitable for traffic policemen operation without any experience of computer operation. 8. It has the function of two-dimensional reconstruction analysis and three-dimensional reconstruction analysis of traffic accident scene. It can automatically generate three-dimensional accident scene according to the actual situation of traffic accident, and reproduce the whole process of traffic accident occurrence with three-dimensional picture. At the same time, it can also carry out two-dimensional reconstruction analysis from the perspective of forward and downward, so as to confirm the responsibility of accident. Provide a complete image basis. 9. The "Tietong Fast Text Input Method" of independent intellectual property rights makes it faster and easier for traffic police to input text. 10. In order to meet the different needs of traffic policemen all over the country, a large number of practical functions have been customized and developed, and each functional detail has been carefully designed with the goal of "maximizing the speed of field map drawing". (1) Nested printing function of field maps. (2) It has the function of intelligent distribution and dispersal of annotated data, which makes the scene map clearer. (3) Multi-datum line data labeling. (4) Multi-trailer linkage control function. 
11. It has abundant road shape drawing template and powerful pre-set road database function. )[TEUGK5OQC9E6XC~AZX6O.png)
12. It can have a graphical tool for making exploration records, which is simple and intuitive. At the same time, the system can be connected with the accident information processing system implemented by the Ministry of Public Security. 13. Simple accident handling procedures are available, and transcripts of inquiry and interrogation are available. 14. Have a list of seized articles and a list of items left over from road traffic accidents. 15. Have the certificate of compulsory administrative measures of public security traffic management and the registration form for blood (urine) extraction of the parties concerned. 
16. Laser-assisted ranging can support Bluetooth wireless communication. 17. It can support the new touch operation under Microsoft Windows 10 operating system. It can operate freely with a stylus or finger. V. Application Program Solution 1. Tablet PC Photography In this scheme, a two-in-one tablet computer is used to take pictures of the accident scene directly. After that, a three-dimensional scale-free rapid survey and disposal system is used to analyze and process a large number of pictures taken, which can automatically generate the scene map of road traffic accidents and the scene record map of road traffic accidents. Scheme 3.
