Embodiment Construction

[0033] Embodiment of the lane line detection method in the vehicle test site:

[0034] The lane line detection method of the vehicle test site proposed in this embodiment is based on a vehicle test site, the vehicle test site, including roads, such as figure 1 through lane markings as shown and / or as figure 2 The patterns shown for curve lane markings, straight lane markings and / or curve lane markings are all in the shape of white broken line distance confirmation lines. This lane line applies to the dedicated lane line for automatic driving in closed parks. As a specific implementation, straight lane lines and curve lane lines are set on the road. Of course, according to specific experimental requirements, only one of the straight lane lines and curve lane lines can be set on the lane, and this The invented lane line is a marking line with certain coding ability.

[0035] Under normal circumstances, the equipment for collecting information on lane lines is the monocular v...

Abstract

The invention relates to a vehicle experiment site and a lane line detection method thereof, and belongs to the technical field of intelligent driving control. The vehicle experiment site comprises aroad, a straight lane line and / or a curve lane line are / is arranged on the road, and the pattern of the straight lane line and / or the curve lane line adopts the shape of a broken line vehicle distanceconfirmation line. The lane line designed by the invention is different from a linear lane line on an actual road surface, and is not easily interfered by other marked lines or ground scratches, so that lane line detection equipment can carry out accurate identification and detection under the scenes of backlight, rainy days, blurring and more vehicle shielding; therefore, the invention is betterin stability, robustness and anti-interference performance during the detection of the lane line. The lane line is also suitable for a special lane line for automatic driving in a closed park.

Description

technical field [0001] The invention relates to a vehicle experiment site and a lane line detection method thereof, belonging to the technical field of intelligent driving control. Background technique [0002] The use of vision-based lane line detection is an effective vehicle-assisted positioning method. Compared with GPS, it has the advantages of large amount of detection information and no interference from the external environment. It has great advantages in road marking detection and recognition. Through the detection and recognition of lane lines, the road recognition and tracking functions in the process of automatic driving are completed, and the lateral positioning of automatic driving vehicles is realized. At present, most of the lane lines for positioning based on vision technology rely on the standard yellow or white virtual and solid straight lane lines on the road. Due to the large distance between the dotted lines, the standard long lane lines are prone to ha...
