A traffic navigation prompt method and system thereof

Abstract

The invention discloses a traffic navigation prompting method and system thereof, comprising generating a navigation route from the current position of a target object to the target position; marking the current position of the target object in the navigation route with a first mark, and updating the first mark in real time; Extract all the traffic lights included in the navigation route; judge whether the traffic lights include a countdown timer; if not, extract the traffic lights as the target signal lights; mark the target lights in the navigation route with the second mark; extract and first Mark a second mark with the shortest distance; acquire the image of the target signal light at the second mark; calculate the red light countdown length and green light countdown length of the target signal light respectively according to the image; when the target signal light switches to the red light state at the moment, the user Output the countdown time of the red light; when the target signal light switches to the green light state, output the countdown time of the green light to the user.

Description

technical field [0001] The invention relates to the field of traffic passage, in particular to a traffic navigation prompting method and system thereof.
