Problems solved by technology

[0002] The simulation of automatic driving needs to drive on a more realistic road. The lane lines on the road are an important basis for judging whether the parking space is correct. The lane lines are included in the map. All lanes must have corresponding maps, and the width of the lane cannot be adjusted. Or all lanes need to be modeled and produced, which is very inefficient and takes a long time to produce

Embodiment 1

[0068] figure 1 It is a flow chart of the method for quickly drawing traffic lanes involved in the present invention.

[0069] Such as figure 1As shown, the present embodiment 1 provides a method for quickly drawing traffic lanes, including: setting the parameters of the lane; creating a corresponding number of traffic lanes according to the parameters of the lane; setting the Bezier curve parameters of the center line of the lane line in the traffic lane; The parameters of the lane and the Bezier curve of the center line of the lane line determine the Bezier curve parameters of the corresponding lane line in the lane; draw the lane according to the Bezier curve parameters of the lane; connect the lanes of different lanes; and store the drawn The lane line, realizes the rapid drawing of the center line of the lane line and multiple lane lines in the lane line, avoiding the traditional mapping and modeling when drawing lane lines, which is very fast and convenient; it does n...

Embodiment 2

[0101] Figure 6 It is a functional block diagram of the fast lane drawing system involved in the present invention.

[0102] Such as Figure 6 As shown, on the basis of embodiment 1, the present embodiment 2 also provides a fast lane drawing system, including: a lane setting module, which sets the parameters of the lane; a creation module, which creates a corresponding number of lanes according to the parameters of the lane The lane center line setting module is used to set the Bezier curve parameters of the lane line center line in the traffic lane; the lane line setting module is used to determine the Bezier curve of the corresponding lane line in the traffic lane according to the parameters of the lane and the Bezier curve of the lane line center line Parameters; a drawing module, drawing a traffic lane according to the Bezier curve parameters of the traffic lane; a connection module, connecting traffic lanes of different lanes; and a storage module, storing the drawn tra...

Abstract

The invention belongs to the field of automatic driving simulation, and particularly relates to a rapid lane drawing method and system, and the method comprises the steps: setting parameters of a lane; creating a corresponding number of lanes according to the parameters of the lanes; setting a Bezier curve parameter of a lane line center line in the driving line; determining a Bezier curve parameter of a corresponding lane line in the driving line according to the parameters of the lane and the Bezier curve of the center line of the lane line; drawing a lane according to the Bezier curve parameters of the lane; the lane lines are connected with different lanes. According to the lane line drawing method, the drawn lane lines are stored, the lane line center lines and the lane lines in the lane lines are rapidly drawn, mapping and modeling during traditional lane line drawing are avoided, and the lane line drawing method is very rapid and convenient.

Description

technical field [0001] The invention belongs to the field of automatic driving simulation, and in particular relates to a method and system for quickly drawing traffic lanes. Background technique [0002] The simulation of automatic driving needs to drive on a more realistic road. The lane lines on the road are an important basis for judging whether the parking space is correct. The lane lines are included in the map. All lanes must have corresponding maps, and the lane width cannot be adjusted. Or all lanes need to be fully modeled and produced, which is very inefficient and takes a long time to produce. [0003] Therefore need to design a kind of new traffic lane fast drawing method and system based on above-mentioned technical problem. Contents of the invention [0004] The purpose of the present invention is to provide a method and system for quickly drawing traffic lanes. [0005] In order to solve the above-mentioned technical problems, the present invention provid...
