Problems solved by technology

[0006] For this reason, the technical problem to be solved by the present invention is that in the prior art, motor vehicles cannot be prompted to slow down in time when passing a pedestrian crossing, and motor vehicles are prompted to stop and give way when pedestrians pass by, and at the same time, the illegal behavior of not avoiding pedestrians according to law cannot be corrected. Carry out automatic recording, thereby propose an automatic reminder system and method when a motor vehicle passes a pedestrian crossing

Embodiment 1

[0040] This embodiment provides an automatic reminder system when a motor vehicle passes a pedestrian crossing, such as figure 1As shown, it is set on a road without a pedestrian crosswalk controlled by signal lights, including the pedestrian crosswalk and the pedestrian crosswalk stop line set behind the pedestrian crosswalk, and also includes a video tracking unit, a prompt unit and a data processing unit set at the intersection. The video tracking unit tracks the pedestrian crossing of motor vehicles and every pedestrian passing on the crosswalk. The video tracking unit is realized by an image tracking system arranged at the intersection, including a camera and software for tracking and processing the images obtained by the camera.

[0041] The prompt unit is a display screen arranged in the direction of motor vehicle traffic. When the motor vehicle passes the pedestrian crosswalk warning marking line, it prompts the motor vehicle to slow down. Regardless of whether there a...

Embodiment 2

[0050] In this embodiment, an automatic prompting system for a motor vehicle passing through a pedestrian crossing is provided, such as figure 2 As shown, the system is installed on a road with a pedestrian crossing but no traffic lights, including the pedestrian crossing and the pedestrian crossing stop line in front of the pedestrian crossing. There are waiting areas for crossing pedestrians on both sides of the pedestrian crossing, and a pedestrian crossing warning is set behind the pedestrian crossing stop line. As for the marking line, several equidistant marking lines are set between the pedestrian crossing warning marking line and the pedestrian crossing stop line, and several distance marking points are also set on the pedestrian crossing.

[0051] The automatic prompting system also includes a video tracking unit, a display screen and a data processing unit arranged at the crossing, the video tracking subunit includes a video acquisition subunit and an image recogniti...

Abstract

The invention provides an automatic prompt system and a method during passing of a motor vehicle through a pedestrian crosswalk. The system comprises a video tracking unit, a prompt unit and a data processing unit; when the motor vehicle passes through a warning marking line of the pedestrian crosswalk, deceleration prompt is performed, and photographing is performed if no deceleration is performed; if a pedestrian passes through and a distance between the motor vehicle and the pedestrian is detected as less than a set threshold, a display screen prompts stop to avoid the pedestrian; and if the motor vehicle passes over a stop line, when the distance between the pedestrian and the motor vehicle in an advancing direction is less than the set threshold, the motor vehicle is photographed to provide a basis for subsequent traffic law administration. With the adoption of the scheme, the motor vehicle is prompted in advance to decelerate when the motor vehicle passes through the pedestrian crosswalk, and when the pedestrian passes through, the stop can be automatically prompted, so that an accident of a pedestrian bruise by the motor vehicle when the pedestrian passes through the pedestrian crosswalk can be avoided, and the walking safety of the pedestrian on the pedestrian crosswalk is improved.

Description

technical field [0001] The invention relates to the field of traffic law enforcement, in particular to an automatic prompting system and method for a motor vehicle passing a crosswalk. Background technique [0002] With the rapid development of social economy, road traffic is becoming more and more busy, and the contradiction between motor vehicles and pedestrians is very prominent. Chinese-style crossing the road has attracted the attention of the world. How to improve the efficiency of road traffic on the premise of ensuring the safety of pedestrians crossing the road is people's attention. focus. The best way to ensure the safety of pedestrians and improve the efficiency of road traffic is to separate pedestrians and vehicles by means of underground pedestrian crossings or overpasses. Where there is no condition, the only way to control pedestrian crossing lights is to reduce road traffic efficiency. [0003] In order to improve the efficiency of road traffic, the traffi...
