Embodiment Construction

[0046] The preferred embodiments of the present invention are specifically described below with reference to the accompanying drawings, wherein the accompanying drawings constitute a part of the present application, and together with the embodiments of the present invention, are used to explain the principles of the present invention, but are not used to limit the scope of the present invention.

[0047] Method embodiment

[0048] A specific embodiment of the present invention discloses a method for controlling the projection of sidewalk guidance signs, such as figure 1 shown, methods include:

[0049] S1. Detect whether there is a pedestrian in the pedestrian waiting area;

[0050] S2. If there is a pedestrian in the waiting area, control the projection device to project a guide sign on the road.

[0051] S3. Detect the position of the pedestrian on the road. If the pedestrian has passed the road or the projection time is longer than the longest projection time, the projectio...

Abstract

The invention relates to a sidewalk guide sign projection control method, and belongs to the field of traffic control, and the method comprises the steps: detecting whether there is a pedestrian in a pedestrian waiting area; if the pedestrian exists in the waiting area, controlling projection equipment to project a guide sign to a road; and detecting the position of the pedestrian in the road, if the pedestrian passes through the road or the projected time is longer than the longest projection time, controlling the projection equipment to stop projecting the guide sign to the road, otherwise, dynamically adjusting the projection area range of the guide sign according to the position of the pedestrian on the road. Namely, the projection range of the sidewalk guide mark is dynamically adjusted. The traffic efficiency is improved while the road traffic safety is improved.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a projection control method for sidewalk guidance signs. Background technique [0002] Most of the zebra crossings on the road are drawn directly on the road surface by hand. With long-term use, there will be fading, aging, grinding, etc. The zebra crossings on the road need frequent maintenance. Lack of conditions for regular maintenance, with the development of technology, there is also a proposal to use projection devices to project zebra crossings. By projecting virtual zebra crossings instead of manually drawn zebra crossings on the road, zebra crossings can be displayed clearly for a long time and maintenance is reduced. [0003] The current control method for virtual zebra crossings is based on the traffic light signals at the intersection. For intersections without traffic lights, the projection cannot be effectively controlled. At the same time, since the project...
