Abstract

The invention discloses an intelligent traffic passerby protection method, which relates to the field of intelligent traffic, and comprises the following steps: firstly, collecting image coordinates of a first passerby on a pedestrian crosswalk by adopting a camera, and enabling the image coordinates to be actual first coordinates on the pedestrian crosswalk; solving a first incident angle of the protection lamp irradiating the first reflector, and controlling the first reflector to rotate around a first rotating shaft; solving a second incident angle of the protection lamp irradiating the second reflector, and controlling the second lens to rotate around the second rotating shaft; and finally, controlling the taper angle of the protection lamp according to the optical path length. By adjusting the first reflector and the second reflector to turn over, the position coordinate value of pedestrians on the pedestrian crosswalk irradiated by the protection lamp can be conveniently controlled; the protective lamp plays a role in illuminating passersby and can also highlight the position of the passersby, so that vehicles running at night can clearly see the position of the passersby, and accidents are reduced; the method is simple in calculation, high in precision, simple in equipment and convenient to install, popularize and use.

Description

technical field

[0001] The invention relates to the field of intelligent traffic, in particular to a method for protecting pedestrians in intelligent traffic. Background technique

[0002] Traffic refers to public travel and passenger and cargo transportation between road systems (ground, underground, elevated, waterways, cableways, etc.); before humans used vehicles as a means of transportation, urban public travel was mainly on foot, or by riding livestock or sedan chairs. Waiting for transportation; the transfer of goods is mostly carried by shoulders or transported by simple means of transport; after the appearance of vehicles, horse-drawn carriages quickly became the main means of urban transportation; in 1819, public carriages first appeared on the streets of Paris for the urban public to rent and ride. Generated urban public transport, created a new era of urban transport.

[0003] In the process of night traffic, due to the abuse of far-off lights and the poor visio...

Embodiment Construction

[0029] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0030] Such as Figure 1-5 As shown, in the first embodiment of the present invention, a method for protecting passers-by in intelligent traffic is provided, the method comprising:

[0031] Step S1, using a camera to collect images on the crosswalk;

[0032] Step S2, in response to recognizing the body limbs of the first passer-by on the image, collecting the image coordinates (X' of the first passer-by on the image) i ,Y′ i );

[0033] Step S3, the image coordinates (X' i ,Y′ i ) is transformed into the actual first coordinate (X i ,Y i ); The i is the position code of the first passer-by on the crosswalk; the horizontal coordinate value X i and the vertical coordinate value Y i The coordinate system where it is located is set up on the pedestrian crosswalk, and the coordinate system includes a coordinate origin O, an X axis, a Y axis, and a Z axis....
