Embodiment 1

[0023] Embodiments of the present invention provide a method for acquiring traffic conditions through images, such as figure 1 As shown, the method includes:

[0024] 101. Acquire video images of each traffic intersection captured by cameras on each traffic intersection in real time.

[0025] It should be noted that, in order to grasp the running status of vehicles at each traffic intersection, the camera is often set up at a suitable position at the traffic intersection, such as the isolation belt above the road and in the middle of the road, to monitor the running conditions of vehicles on the road at each traffic intersection in real time. Vehicle running conditions include vehicle queuing conditions, traffic light waiting conditions, parking time, vehicle turning left and right, and other information. In order to enable the video processing center to obtain the traffic status of each road through the video images of each intersection captured by the camera, after the came...

Embodiment 2

[0045] An embodiment of the present invention is a device for acquiring traffic conditions through images, such as Figure 4 As shown, the device includes: an acquisition unit 21 , an image processing unit 22 , and a space and time estimation unit 23 .

[0046] The acquiring unit 21 is configured to acquire video images of each traffic intersection captured by cameras on each traffic intersection in real time.

[0047] The image processing unit 22 is configured to perform video processing and analysis on the video image to obtain the traffic status of each traffic intersection.

[0048] The space and time estimation unit 23 is used to estimate the space and time of the roads between the traffic intersections according to the traffic status of the traffic intersections and the pre-established traffic processing model, and obtain the distance between the traffic intersections. The traffic status of each road.

Abstract

The invention discloses a method and a device for obtaining traffic states through images, which relate to the field of urban traffic road condition information treatment and application, can timely and accurately obtain the practical road traffic states, improve timeliness and accuracy of traffic information used by users, and facilitates travel planning of the users. The method includes obtaining video images of all traffic intersections shot by cameras on all the traffic intersections in real time, performing video processing and analyzing on the video images to obtain the traffic states of all the traffic intersections, and performing space and time speculation on roads among all the traffic intersections according to the traffic states of all the traffic intersections and a preset traffic processing model to obtain the traffic condition of each road among all the traffic intersections. Embodiments of the method and the device for obtaining traffic states through the images are mainly used in processes of obtaining the traffic states through the images.

Description

technical field [0001] The invention relates to the field of processing and application of urban traffic road condition information, in particular to a method and device for acquiring traffic status through images. Background technique [0002] Today, with the rapid development of urban traffic, urban roads are becoming increasingly complex, and traffic congestion has gradually become an important problem in urban traffic. For customers, the very important point of traffic information is that it needs to accurately and timely reflect the actual traffic information at that time, and the operation of vehicles on the road through the camera can reflect the actual traffic information at that time, but how to use the camera The image acquisition corresponding to the captured vehicle running conditions on the road is carried out in the traffic state, and there is no relevant technical solution at present. Contents of the invention [0003] Embodiments of the present invention p...
