Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention lies in the problems of the pre-prompt method of breaking the line in the prior art, which requires a large number of cameras, a large amount of collected data, and a large amount of calculation, thus proposing a method that only requires one camera and Method and system for preventing key transport vehicles from breaking line violations with reduced amount of collected and processed data

Embodiment 1

[0037] The present embodiment provides a method for preventing the violation of the line pressing of key transport vehicles. The flow chart is as follows: figure 1 shown, including the following steps:

[0038](1) Use a camera set on the top of the vehicle to collect the image in front of the vehicle running. The camera is arranged at a certain position on the top of the vehicle. When the vehicle is driving on the road, the camera captures the road conditions ahead, including the marking lines on both sides of the vehicle, and the image information is collected by the camera. The marking lines on the road generally include solid lines and dotted lines. The solid lines are not allowed to cross, and the dotted lines are allowed to cross.

[0039] The marking lines on the road are divided into yellow lines and white lines. The yellow line is used to distinguish lanes in different directions. It is generally drawn in the middle of the road, like an isolation belt, dividing the r...

Embodiment 2

[0046] In this embodiment, on the basis of the above-mentioned Embodiment 1, the dotted line in the marked line is further judged. No matter what type of dashed line, it can be crossed, so when the dashed line enters the safe area, there is no need to prompt and alarm. However, when the vehicle is running, it is not allowed to drive on the line. Therefore, if the dotted line is in the safe area for a long time, it means that the vehicle is driving on the line. This method is illegal and needs to be prompted. Therefore, the method for preventing the illegal behavior of pressing the line of key transport vehicles in the present embodiment is as follows: figure 2 It also includes comparing the position of the dotted line image with the position of the safe area, and when the dotted line image enters the safe area and the duration reaches a preset time threshold, a line pressure warning prompt is performed. The time here can be set to 1-10 minutes as required, such as 3 minutes,...

Embodiment 3

[0049] In this embodiment, two methods for determining the safe area are provided for the above-mentioned method for preventing the illegal behavior of pressing the line of a key transport vehicle. Whether the setting of the safety area is appropriate or not directly affects the subsequent relationship between the vehicle and the position of the marking line.

[0050] method one:

[0051] When the vehicle is moving normally and the left wheel is close to the left marking line, the position of the left marking line in the image collected by the camera is taken as the left edge of the safe area; when the right wheel is approaching the right marking line, the The position of the right marking line in the image captured by the camera serves as the right edge of the safety line, and the area between the left and right edges serves as the safety area.

[0052] After the safety zone is established according to this method, the vehicle is normally driven, and the marking lines on bot...

Abstract

The invention provides a method for preventing the line pressing unlawful act of an important transport vehicle. The method includes the steps that an image of the road in front of the vehicle is collected through a camera, the dotted line position and the full line position in front are obtained, a safety region is set in a collecting visual field of the camera, marker lines on the two sides of the vehicle are not located in the safety region when the vehicle is driven normally, and when the position of a full line image is located in the safety region, a line pressing early warning prompt is given. According to the method, the problems that in the prior art, data of the two sides of the vehicle need to be collected and processed respectively, two cameras are needed, and the data collecting and processing amount is large are solved and cost is reduced. The position of the vehicle relative to the marker lines is judged through the preset safety region, the method is easy to achieve, the position of the safety region is reasonably set according to different vehicles and current road information, the accuracy degree for judging the positions between the marker lines and the vehicle is improved, and therefore the accuracy of line pressing early warning is improved.

Description

technical field [0001] The invention relates to a method for identifying the line-breaking of vehicles, in particular to a system and method for preventing illegal acts of line-breaking of key transport vehicles. Background technique [0002] Road traffic safety regulations stipulate that vehicles cannot suppress special ground markings such as double yellow solid lines, single yellow solid lines, and white solid lines when driving on the road. line driving behavior. In terms of the degree of violations, most of the violations are relatively low, and in most cases the drivers do not violate the rules, but because of misjudgment or ignorance. If the driver's illegal behavior of pressing the line can be warned in advance, so that the driver is aware of the risk of the imminent line pressing, it will greatly facilitate the driver to adjust the vehicle running track in time during driving, and reduce or avoid the occurrence of the line pressing situation . [0003] In order t...
