Abstract
The invention provides a method and a system for inspecting a large screen video. Before the large screen video is inspected, a video inspecting scheme is only required to be established in advance, and a one-key operation can be performed in the process of executing the scheme and the system can inspect the large screen video automatically according to a scheme design. By the method and the system, the efficiency of inspecting the video is greatly improved and the 100% accuracy of video switching can be achieved under the condition that an executive staff is not required to be familiar with a video camera serial number and large screen inspecting equipment.
Description
Technical field
The present invention relates to the intelligent transportation applied technical field, be specifically related to a kind of large-size screen monitors video routing inspection method and system.
Background technology
At present; Video frequency pick-up head monitoring road traffic situation is generally adopted in China's city main roads or key area; Each video frequency pick-up head all has a fixing number information; And it can only monitor fixing scene domain, and each video frequency pick-up head can be sent to the video image in the scene domain that monitors traffic police command centre.
When need control or have road traffic condition in the process that major event or traffic police performing important duties comprehensively; Need carry out tours of inspection to the video image of all video frequency pick-up head monitoring ranges; When grasping urban highway traffic and security situation, at this moment can check the video image of whole cameras through being arranged on the inner large-size screen monitors video routing inspection equipment of traffic police command centre comprehensively.
Large-size screen monitors video routing inspection equipment has a plurality of monitors, and the monitor number of large-size screen monitors video routing inspection equipment is 2 * 3 (totally 6 monitor 2 row 3 row), 2 * 4 (totally 8 monitor 2 row 4 row), 4 * 6 (totally 24 monitor 4 row 6 row), 4 * 8 (totally 32 monitor 4 row 8 row) generally speaking.Wherein each monitor all has fixing numbering, when needs are realized video routing inspection through the monitor of large-size screen monitors video routing inspection equipment, only needs to confirm that each monitor shows that the video image of the video frequency pick-up head monitoring of which numbering gets final product.When carrying out video routing inspection, the video image of the video frequency pick-up head monitoring of reference numeral information is sent to the monitor of reference numeral.
Look the monitor number that screen is patrolled and examined equipment owing in general the video frequency pick-up head quantity in the urban road deploy be far longer than large-size screen monitors.Therefore if will utilize the large-size screen monitors video routing inspection equipment of minority to check the video image of whole video frequency pick-up head monitoring of having disposed; Just need to specify rational video routing inspection scheme, and the time according to the rules switches to the video image of the video frequency pick-up head monitoring of appointment and checks on the monitor of large-size screen monitors video routing inspection equipment of appointment and reach the purpose of patrolling and examining.
After traffic police command centre confirms the scheme of patrolling and examining, when promptly confirmed need the video image of the video frequency pick-up head monitoring of which numbering to be sent on the monitor of large-size screen monitors video routing inspection equipment of reference numeral.In the prior art, after learning the scheme of patrolling and examining, the monitor that traffic police command centre adopts manual type the video image of designated camera head monitor to be switched to the large-size screen monitors video routing inspection equipment of appointment is is on time patrolled and examined and is checked.This will negate the personnel of duty video switch clear fully to the monitor numbering that is deployed in the large-size screen monitors video routing inspection equipment in all video frequency pick-up heads numberings and the traffic police command centre on the urban road; Otherwise very easily cause video switch incorrect, can't realize the purpose of patrolling and examining; And video switch is carried out in manual work, switch step of every execution; The video image that all can only the video frequency pick-up head of a numbering be monitored switches on the monitor of large-size screen monitors video routing inspection equipment of reference numeral; So, nervous when the time, under the heavy situation of patrol task; Adopting manual work to carry out video switch wastes time and energy, and efficient is too low.
Summary of the invention
To be solved by this invention be in the prior art when carrying out the video routing inspection task, cross and wrong technical problem occurs and then the large-size screen monitors video routing inspection method and system of a kind of switching video signals automatically to the large-size screen monitors video routing inspection equipment monitor device of correspondence are provided low and easily but need the artificial video image that the video frequency pick-up head of correspondence is monitored to switch to efficient on the monitor of corresponding large-size screen monitors video routing inspection equipment.
