A method and apparatus for image interception

Abstract

The embodiment of the invention provides a picture intercepting method and a device, which are applied to a video network. The video network comprises a first protocol conversion server, a second protocol conversion server, and a network camera. The second protocol conversion server is connected with the network camera. The method comprises generating a video stream calling instruction by the first protocol conversion server ;sending the video stream retrieval instruction to the second protocol conversion server; receiving a real-time video stream sent by the second co-transfer server; carrying out image interception on the real-time video stream to obtain one or more frames of pictures; and presenting the one or more pictures. In accordance with an embodiment of the present invention, the invention realizes the image interception function of the real-time video stream in the video network, improves the user experience, and obtains the preview picture of the real-time video stream based on the image interception operation, which can preview the real-time video stream by using the preview picture before playing the real-time video stream, and does not need to upload the picture manually, thereby reducing the labor cost and human error.

Description

technical field [0001] The invention relates to the field of video networking, in particular to a method and device for capturing pictures. Background technique [0002] With the rapid development of science and technology, Internet of Vision technology has been widely used in various industries, such as telemedicine, security, emergency command and other fields. The application of Internet of Vision technology has brought great convenience. [0003] At present, in the process of building a monitoring system, the Internet of Vision technology can be applied to ensure the timeliness and security of video surveillance. In the monitoring system based on the Internet of Vision technology, since the monitored video streams are all real-time video streams, The Internet of Things usually does not store real-time video streams, which makes it impossible to realize the screenshot function, and then cannot generate preview images to browse real-time video streams. [0004] In the pri...

[0003] At present, in the process of building a monitoring system, the Internet of Vision technology can be applied to ensure the timeliness and security of video surveillance. In the monitoring system based on the Internet of Vision technology, since the monitored video streams are all real-time video streams, The Internet of Vision usually does not store real-time video streams, which makes it impossible to realize the screenshot function, and then cannot generate preview images to browse real-time video streams

[0004] In the prior art, since the screenshot function cannot be realized, usually the staff can only manually upload the picture, and then use the picture as the preview picture of the real-time video stream, and the manually uploaded picture cannot play the role of previewing the real-time video stream. And if you set different preview images for different real-time video streams, the manual upload method is too cumbersome and prone to errors
