Problems solved by technology

Due to the limited shooting speed of the camera, there needs to be a certain reaction time between two captures, and when shooting, it is often encountered that vehicles on multiple lanes pass through the road section at the same time in a very short time interval. The camera cannot respond in time, which will lead to missed shots, or because the capture is not timely, the complete vehicle information cannot be seen in the captured photos of passing cars, resulting in unavailable photos of passing cars and inefficient use of photos

Embodiment Construction

[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] like figure 1 as shown, figure 1 It is a flowchart of a method for collecting traffic information in an embodiment of the present invention. The traffic information collection method of this embodiment includes:

[0037] Step S10, receiving the trigger signal of continuous vehicle passing, and starting the multiplexing mode;

[0038] In this embodiment, when there are vehicles passing successively in each lane, in order to avoid missed or slow shots due to the slow reaction speed of the camera, it is necessary to start the multiplexing mode, that is, only take pictures within the range that the camera can respond. A passing photo is used as a multiplex.

[0039] Step S20, in the multiplexing mode, take photos of passing vehicles according to the preset shooting frequency, and designate the photos taken as m...

Abstract

The invention disclose a traffic information acquisition method and an apparatus thereof. The traffic information acquisition method comprises the following steps: receiving a triggering signal of continuously passed cars and starting a reuse pattern; shooting a passed car photo as a preset shooting frequency under the reuse pattern and taking the photo as a reuse photo. In the invention, a photo reuse technology is used so as to avoid situations of missing shooting or performing late shooting. Using one photo to reflect the situations of a plurality of continuously passed cars so that shooting times of a camera can be minimized, a service life of the camera can be prolonged and a utilization rate of the photo can be effectively raised.

Description

technical field [0001] The invention relates to the field of traffic monitoring, in particular to a method and device for collecting traffic information. Background technique [0002] In the traffic monitoring system, electronic monitoring equipment is usually installed on each designated intersection or road section, such as a camera with a vehicle capture function, etc., to take photos of passing vehicles on the road in time to obtain information about passing vehicles on the road and provide them to Relevant departments analyze and use it to assist the traffic management system to effectively manage the traffic conditions of each road section. [0003] The current commonly used traffic information collection method is to install a camera at a designated intersection or road section to capture a picture of each passing vehicle on each lane. Due to the limited shooting speed of the camera, there needs to be a certain reaction time between two captures, and when shooting, i...
