Embodiment Construction

[0041] The specific implementation manners of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0042] A GPS-based road traffic depth acquisition system, such as figure 1 As shown, it includes a central processing unit and a positioning module, a communication module, an accident scene acquisition module and an accident recording module respectively connected to the central processing unit;

[0043] The positioning module is used to obtain the position information of each position of the accident scene, which includes GPS positioning device and Beidou positioning device. The positions of the accident scene include the collision point, the starting position of all parties in the accident, the final position of all parties in the accident and the landmark position of the accident site. The landmarks at the accident site are fixed buildings, traffic lights, pedestrian crossings or trees at the accident site;

[0044] The acci...

Abstract

The invention discloses a GPS-based road traffic depth acquisition system. The road traffic depth acquisition system comprises a central processing unit and a positioning module, a communication module, an accident scene acquisition module and an accident recording module which are connected with the central processing unit separately; the positioning module is used for acquiring position information of each position of an accident scene and comprises a GPS positioning device; the accident recording module is used for recording related information of an accident; the accident scene acquisitionmodule is used for collecting photos of the accident scene, and comprises a camera for collecting photos of different angles on the accident scene; the central processing unit is used for generatinga road accident scene graph with position information according to the photos at different angles in the accident scene acquired by the accident scene acquisition module and in combination with the position information acquired by the positioning module; and the communication module is used for communicating with a cloud end, and sending the information acquired and processed by the system to thecloud end. According to the road traffic depth acquisition system, the GPS data is acquired, the information recording is comprehensive, the processing speed is high, and the application prospect is extremely high.

Description

technical field [0001] The invention belongs to the technical field of road traffic and relates to a GPS-based road traffic depth collection system. Background technique [0002] In road traffic operation, a large number of accidents and traffic congestion caused by traffic construction, accidents, vehicle breakdowns and other traffic events every year have a great impact on the safety and smooth travel of the people. [0003] When dealing with traffic accidents, it is often necessary to collect detailed information about road traffic accidents. At present, such operations mainly rely on manual completion, which specifically includes the following steps: [0004] (1) Fill out the traffic accident scene information record form; [0005] (2) Hand-painted site map; [0006] (3) Road information measurement, including road width, location information of road signs, etc.; [0007] (4) Take pictures on the spot. [0008] Although manual processing can also collect relevant inf...
