Specific embodiment
Referring to Fig.1, a kind of signal lamp prompt system based on image recognition proposed by the present invention, comprising:
Detection module is waited, for detecting whether target vehicle is waiting traffic lights.
It waits detection module to be specifically used for: obtaining the location information of target vehicle；Obtain the speed of target vehicle；In target
The location information instruction target vehicle of vehicle is in the preset range of intersection and the speed of target vehicle is less than default
Speed threshold value when, judge target vehicle wait traffic lights.
In concrete scheme, the location information of target vehicle is positioned first, then obtains the speed of target vehicle, passes through target
The location information of vehicle determines that target vehicle is in the preset range of intersection, and the speed of target vehicle is less than default
Speed threshold value when, illustrate at this time target vehicle intersection stop or slow down, at this point, judge target vehicle road friendship
Prong waits the traffic lights of intersection setting.
Lane information obtains module, for determining target vehicle institute when detecting that target vehicle waits traffic lights
The lane at place.
Lane information obtains module and is specifically used for: when detecting that target vehicle waits traffic lights, acquiring target carriage
The lane markings image in locating lane；The lane markings image in the lane according to locating for target vehicle, determines locating for target vehicle
Lane.
Lane information obtains module and is specifically used for: when detecting that target vehicle waits traffic lights, obtaining target carriage
Position；According to the position of target vehicle determine target vehicle locating for lane.
In concrete scheme, the lane markings image in lane locating for target vehicle is acquired by image capture device, is passed through
Image recognition technology identify lane markings image in lane markings, according to lane markings determine target vehicle locating for lane
(left turn lane, Through Lane or right-turn lane)；
Alternatively, the position of positioning target vehicle, can determine lane locating for target vehicle according to the position of target vehicle
(left turn lane, Through Lane or right-turn lane).
Signal lamp matching module, it is matched with target vehicle driving direction for the determination of the lane according to locating for target vehicle
Echo signal lamp；
Time-obtaining module is converted to the target latency time of green light for obtaining echo signal lamp by red light.
