Problems solved by technology

However, the monitoring efficiency of the current existing technology is relatively low. If the front-end equipment can send some monitoring image related information, such as absolute time, image characteristics, and specific area event occurrence signs, etc., in the video stream together with the image information when sending the monitoring image Sending it to the monitoring center can better meet the monitoring needs, save the processing time of the monitoring center, and improve efficiency

Embodiment 1

[0047] In this embodiment, while the front-end equipment is sending the monitoring image, it sends the absolute time identifier, the image acquisition location identifier and the image sequence identifier as monitoring image related information to the monitoring center according to a predetermined fixed time interval (for example, optional at the second level). , so that the monitoring center can obtain the absolute time of the front-end equipment. Such as Figure 5 As shown, it is a flowchart of a monitoring image-related information transmission method according to Embodiment 1 of the present invention, including the following steps:

[0048] In step S501, the front-end equipment collects surveillance images, and acquires surveillance image-related information associated with the surveillance images, wherein the surveillance image-related information includes image collection location identifiers, image sequence identifiers, and absolute time identifiers.

[0049] Step S502...

Embodiment 2

[0052] In this embodiment, monitoring image-related information different from the above-mentioned embodiment 1 can be transmitted, such as monitoring event occurrence identification, which means that the front-end equipment divides the region of interest (ROI) in the monitoring image, and the front-end The device is equipped with an intelligent identification module, which can detect whether there is a monitoring event in the ROI area. If there is a monitoring event in the ROI area, it will prompt the front-end device, and the front-end device will identify the corresponding monitoring event in time. It is sent to the monitoring center as monitoring image related information, so that the monitoring center can prioritize the transmission unit, and then the monitoring center selectively decodes and monitors according to the image acquisition position identification, monitoring event occurrence identification and image sequence identification in the transmission unit Images assoc...

Embodiment 3

[0054] This embodiment is a combination of the first and second embodiments above. When no monitoring event is detected in the ROI area, the front-end device periodically sends relevant information such as absolute time stamps (same as the first embodiment). Once the front-end equipment detects that a monitoring event occurs, the monitoring event occurrence identification is encapsulated in a separate transmission unit and sent to the monitoring center. Like the second embodiment, the transmission unit header of the transmission unit also contains an information indication identification and urgency indicators. As another embodiment of the present invention, when the front-end device detects that there is a monitoring event in the ROI area, since the sending period of the absolute time stamp can be at the second level, the front-end device can wait until the next absolute time stamp is sent and send the The monitoring event occurrence identification is also encapsulated in the...

Abstract

The invention provides a method for transmitting related information of a monitoring image, which comprises the following steps: front-end equipment acquires the monitoring image and the related information of the monitoring image associated with the monitoring image; the front-end equipment encapsulates the monitoring image and the related information of the monitoring image in corresponding transmission units and transmits the transmission units to a monitoring centre respectively, and sets an information identifier in the transmission unit head of the transmission unit carrying the related information of the monitoring image, wherein the information identifier is used for indicating to the monitoring centre that the transmission unit carries the related information of the monitoring image; and the monitoring centre decapsulates the received transmission unit to acquire the monitoring image and the related information of the monitoring image. The related information of the monitoring image associated with the monitoring image can be transmitted in a code stream so as to improve the monitoring efficiency; and the method has the advantages of excellent format compatibility, easy searching, low cost and excellent extensibility.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a method, system and device for transmitting information related to monitoring images. Background technique [0002] With the continuous development of electronic information technology and the popularization of the network, high and new technologies such as audio and video surveillance have been applied to every field of the national economy. Modern shopping malls and banks are inseparable from modern management and security methods, and urban security monitoring, traffic management, forest fire monitoring, etc. are also inseparable from audio and video monitoring technology. In the prior art, the front-end equipment of the monitoring system directly transmits the collected audio and video content back to the monitoring center, and the monitoring center performs subsequent processing. However, the monitoring efficiency of the current existing technology is relatively low. If...
