Embodiment 1

[0049] see figure 1 , figure 1 It is a schematic flowchart of a method for controlling movement of a warning sign disclosed in an embodiment of the present invention. Such as figure 1 As shown, the movement control method of the warning sign may include the following steps:

[0050] 101. When it is detected that the vehicle stops moving due to an accident, the movement control device of the warning sign acquires the vehicle heading angle information of the vehicle and acquires the first lane line information of the lane where the vehicle is located captured by the camera.

[0051] In the embodiment of the present invention, the warning sign can be placed on the trunk of the vehicle, or attached to the surface of the vehicle, which is not limited in the embodiment of the present invention. When the vehicle stops moving due to an accident, the warning sign can be manually taken out from the trunk by the driver and placed on the ground where the vehicle stops, or the movement co...

Embodiment 2

[0064] see figure 2 , figure 2 It is a schematic flowchart of another warning sign movement control method disclosed in the embodiment of the present invention. Such as figure 2 As shown, the method for controlling the movement of the warning sign may include the following steps.

[0065] 201. When it is detected that the vehicle stops moving due to an accident, the movement control device of the warning sign acquires the vehicle heading angle information of the vehicle and the first lane line information of the lane where the vehicle is captured by the camera.

[0066] Wherein, the vehicle heading angle information is the vehicle heading angle information within a preset time period before the vehicle stops moving.

[0067] 202. The warning sign movement control device determines the road curvature of the lane according to the first lane line information.

[0068] 203. The warning sign movement control device determines the movement distance of the warning sign accordi...

Embodiment 3

[0090] See 3, image 3 It is a structural schematic diagram of a mobile control device for a warning sign disclosed in an embodiment of the present invention. Such as image 3 As shown, the mobile control device of the warning sign may include:

[0091] The acquiring unit 301 is configured to acquire the vehicle heading angle information of the vehicle and acquire the first lane line information of the lane where the vehicle is captured by the camera when it is detected that the vehicle stops moving due to an accident.

[0092] In the embodiment of the present invention, the warning sign can be placed on the trunk of the vehicle, or attached to the surface of the vehicle, which is not limited in the embodiment of the present invention. When the vehicle stops moving due to an accident, the warning sign can be manually taken out from the trunk by the driver and placed on the ground where the vehicle stops, or the movement control device of the warning sign can control the vehi...

Abstract

Embodiments of the invention relate to the field of traffic technology, and disclose a movement control method and device for a warning sign. The method comprises of: when detecting that a vehicle stops due to an accident, acquiring heading direction information of the vehicle and first lane line information of the lane where the vehicle is photographed by a camera; determining the curvature of the lane according to the first lane line information; determining the moving distance of the warning sign according to the type of the lane and the visibility of the current environment in which the vehicle is located; and controlling the warning sign to move to a specified position according to the heading direction information of the vehicle and the curvature. The distance between the specified position and the stop position of the vehicle is the moving distance. According to the embodiments of the invention, the warning sign can be automatically moved without the need of placing the warningsign by a driver or a passenger, thereby reducing the accidents that happen when drivers or passengers place the warning signs.

Description

technical field [0001] The invention relates to the field of traffic technology, in particular to a method and device for controlling movement of a warning sign. Background technique [0002] According to the requirements of traffic regulations, when a vehicle has a traffic accident or breaks down, it is necessary to place a warning sign 50-150 meters away from the direction of the vehicle to remind the vehicles behind to avoid it, thereby reducing the occurrence of secondary collision accidents. However, under situations such as highways, curves, foggy days and nights, the process of placing warning signs by drivers and passengers is very dangerous. Contents of the invention [0003] The embodiment of the invention discloses a movement control method and device for a warning sign, which can automatically move the warning sign, saves the process of placing the warning sign by drivers and passengers, thereby reducing accidents when drivers and passengers place the warning s...
