Problems solved by technology

[0003] At present, cars have gradually entered the family life of the majority of users. On the way of travel, traffic accidents caused by factors such as road conditions, weather, driver's negligence or vehicle congestion occur from time to time, and there are many problems in the process of handling accidents. High risk, the longer the accident processing time, the higher the risk, which will easily cause secondary accidents and traffic jams
[0004] For example, if a traffic accident occurs in the middle of the road, according to the conventional processing method, first turn on the double flashing of the vehicle, set up a warning sign, and then wait for the police to deal with it. traffic accidents and serious traffic jams
[0005] The inventors of the present disclosure found that in the existing traffic accident handling, most of them only adopt on-site photography and on-site measurement to collect parameters. The process of taking photos for evidence collection is cumbersome and the processing speed is slow, which will cause long-term congestion during the peak traffic period. However, simple photo processing in order to quickly relieve congestion is not conducive to the later identification of responsibilities

Embodiment 1

[0048] Embodiment 1 of the present disclosure provides a method for assisting in handling traffic accidents, the implementation process is as follows figure 1 shown.

[0049] after a traffic accident;

[0050] First, identify the accident scene, deal with the event elements that must be resolved on the spot, and lay out three-dimensional feature points at the same time;

[0051] Secondly, use laser scanners and other equipment to collect non-contact information on the accident site, generate a 3D point cloud, and obtain a 3D model of the accident scene. After completing the information collection, vehicles can be evacuated and traffic can be resumed;

[0052] Then, through the point cloud model, the law enforcement elements are supplemented, such as the automatic calculation of the braking length, the vehicle speed calculation, etc., to find out the cause of the accident and register the case;

[0053] Finally, the 3D model, texture picture, video and other information are a...

Embodiment 2

[0087] Embodiment 2 of the present disclosure provides a laser point cloud-based road traffic accident auxiliary processing system, including:

[0088] The data acquisition module is configured to: obtain the three-dimensional point cloud data of the accident scene according to the identification factor of the road traffic accident scene;

[0089] The model building module is configured to: construct a three-dimensional model of the accident scene according to the acquired scene image data and three-dimensional point cloud data, and obtain at least one element of law enforcement according to the three-dimensional model of the accident scene.

[0090] The working method of the system is the same as the road traffic accident auxiliary processing method based on the laser point cloud that embodiment 1 provides, and will not repeat them here.

Embodiment 3

[0092] Embodiment 3 of the present disclosure provides a computer-readable storage medium, on which a program is stored. When the program is executed by a processor, the laser point cloud-based road traffic accident auxiliary processing method described in Embodiment 1 of the present disclosure is implemented. The steps are as follows:

[0093] According to the identification factor of the road traffic accident scene, the 3D point cloud data of the accident scene is obtained;

[0094] According to the acquired scene image data and 3D point cloud data, a 3D model of the accident scene is constructed, and at least one element of law enforcement is obtained according to the 3D model of the accident scene.

[0095] The detailed steps are the same as the laser point cloud-based road traffic accident auxiliary processing method provided in embodiment 1, and are not repeated here.

Abstract

The invention provides a laser point cloud-based road traffic accident auxiliary processing method and system, and the method comprises the following steps: obtaining three-dimensional point cloud data of an accident scene according to an identification factor of the road traffic accident scene; constructing an accident scene three-dimensional model according to the acquired scene image data and three-dimensional point cloud data, and obtaining at least one law enforcement element according to the accident scene three-dimensional model. when a traffic accident occurs, a three-dimensional modelis built through the high-precision three-dimensional laser scanner, part of on-site law enforcement is transfered to the back, the on-site execution and dispute time is shortened, the vehicle congestion time is shortened, and the accident handling efficiency is improved.
