Green message prolonging method, system and device special for old people

Abstract

The invention discloses a special green message prolonging method, system and device for old people. The method comprises the following steps: acquiring facial information of old people through a facerecognition method; obtaining face information of all pedestrians in a sidewalk monitoring range; performing similarity measurement on the face information of the old people and the face informationof the pedestrians, and determining and marking the old people who verify the identities; tracking the marked old people in real time to obtain a street crossing track of the old people; calculatingthe average street crossing speed of the old people according to the street crossing track of the old people; obtaining the distance between the old people and the end point of the sidewalk, and recording as the remaining distance; determining the lowest safe crossing time according to the average speed and the residual distance; and setting countdown of green message extension time according to the lowest safe street crossing time. According to the invention, the street crossing safety problem of the old people can be solved, and the delay of motor vehicles can be reduced to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of pedestrian re-identification, in particular to a method, system and device for extending green letters dedicated to the elderly. Background technique [0002] As my country gradually enters an aging society, the travel safety of the elderly group has gradually received more attention. Due to the physical function of the elderly group, the street-crossing behavior of the elderly is very different from that of ordinary people. Existing street crossing facilities have great disadvantages. The pedestrian crossing design speed is too high, the green light time is short, and the elderly cannot cross the street safely. In order to solve the safety problem of crossing the street of the elderly group, it is necessary to design a green letter extending method and device suitable for the elderly. [0003] The green letter extension device suitable for the elderly that has been researched more in the current field ...
