Abstract

An adjusting system for traffic lights includes a number of image capture units, a processing unit, and a storage system. The number image capture units capture a number of car images. The storage system examines the number of car images to find license plates in each car image, counts the number of the cars, obtains the status of the traffic lights according to the number of the cars, and manages status of the traffic lights correspondingly.

Claims (33)

1. An adjusting system for traffic lights, the adjusting system comprising:

a plurality of cameras to capture a plurality of car images;

a processor; and

a storage connected to the processor and storing a plurality of computerized instructions to be executed by the processor, wherein the processor executes the computerized instructions stored in the storage

to store the plurality of car images from the plurality of cameras,

to examine each of the plurality of car images to find a license plate in each car image,

to receive the license plates and count a number of the cars,

to store a plurality of relationships between the number of the cars to each direction of an intersection and status of the traffic lights correspondingly, and

to receive the number of cars in each direction of the intersection, obtain the status of the traffic lights according to the relationship storing module, and manage status of the traffic lights correspondingly.

2. The adjusting system of claim 1 , wherein the plurality of cameras are to be located on the traffic lights.

3. The adjusting system of claim 1 , wherein the processor further executes the computerized instructions stored in the storage to store the number of the cars in each direction for various moments, to receive the number of the cars in each direction of the intersection, to compare the number of the cars in each direction of the intersection at this moment with the number of the cars at each direction of the intersection at a previous moment, and to manage status of the traffic lights according to a comparing result.

4. An adjusting system comprising:

a plurality of cameras to capture a plurality of pedestrian images of a plurality of pedestrians at an intersection;

a processor; and

a storage connected to the processor and storing one or more computerized instructions to be executed by the processor, wherein the processor executes the computerized instructions stored in the storage

to store the plurality of pedestrian images from the plurality of cameras,

to examine each of the plurality of pedestrian images to find a face in each pedestrian image,

to store a plurality of relationships between a number of the plurality of pedestrians and status of traffic lights correspondingly, and

to receive the number of the plurality of pedestrians in each direction of the intersection, obtain the status of the traffic lights according to the relationship storing module, and manage status of the traffic lights correspondingly.

5. The adjusting system of claim 4 , wherein the plurality of cameras are to be located on the traffic lights.

6. The adjusting system of claim 4 , wherein the processor further executes the computerized instructions stored in the storage to store the number of the plurality of pedestrians at each direction for various moments, to receive the number of the plurality of pedestrians in each direction of intersection, to compare the number of the plurality of pedestrians in each direction of the intersection at this moment with the number of the plurality of pedestrians in each direction of the intersection at a previous moment, and to manage status of the traffic lights according to a comparing result.

7. An adjusting method for traffic lights, the adjusting method comprising:

capturing a plurality of car images at an intersection, and storing the plurality of car images in a storage;

examining each of the plurality of car images to find a license plate in each car image;

receiving the license plates in the plurality of car images, and counting a number of cars in each direction of the intersection;

receiving the number of cars in each direction of the intersection, and obtaining the status of the traffic lights; and

managing status of the traffic lights correspondingly.

8. The adjusting method of claim 7 , further comprising:

capturing a plurality of pedestrian images, and storing the plurality of pedestrian images in the storage;

examining each of the plurality of pedestrian images to find a face in each pedestrian image;

receiving the faces in the plurality of pedestrian images, and counting a number of pedestrians in each direction of the intersection;

receiving the number of pedestrians in each direction of the intersection, and obtaining the status of the traffic lights; and

managing status of the traffic lights correspondingly.
