Problems solved by technology

my country's mobile communication has developed rapidly, but the data traffic charges have always been high, especially for biological real-time monitoring. Due to the high traffic consumption, real-time biological monitoring through mobile data communication transmission is rarely used in actual production.

Embodiment 1

[0025] A low-traffic video communication transmission system such as figure 1 As shown, it includes an image sending end and an image receiving end, both of which are connected through a network, and the image sending end includes: an infrared detector, which is used to collect real-time images formed in the infrared outline of living things; an ordinary camera, which is used to collect living things The real-time color image; the image processor A is used to extract the biological image, and at the same time extracts the changed background image according to the set fixed time interval; the image receiving end includes: an image processor B, which is used to complete the biological image and Synthesis of the background image, while updating the background image stored at the receiving end according to whether the latest background image exists in the received data.

Embodiment 2

[0027] A low-flow video communication transmission method, which divides the entire process of image collection, transmission, and presentation into two parts: an image sending end processing process and an image receiving end processing process.

[0028] Using the aforementioned video communication system, at the image sending end, such as figure 2 As shown, firstly, the infrared detector at the image sending end collects the real-time image formed in the infrared contour of the organism to obtain infrared imaging, and at the same time, the ordinary camera collects the real-time color image of the organism to obtain ordinary imaging, and then the infrared imaging and ordinary imaging are handed over to the image processor A processing, compare the two kinds of imaging, complete the biological image extraction, and extract the changed background image according to the fixed time interval, and then send the extracted image to the image receiving end.

[0029] like image 3 As...

Abstract

The invention discloses a low-traffic video communication transmission system and method. A front infrared detector is used in the system and the method, a real-time infrared image in an infrared outline formed by an active organism and a real-time color image acquired by a common camera are simultaneously transmitted to an image processor, only the corresponding real-time color image in the infrared outline of the organism is transmitted to a far end by image processing, and the background portion beyond the infrared outline of the organism is processed in a periodic spaced static mapping mode, so that the magnitude of video transmission can be greatly reduced. The method can save a lot of mobile communication fee under the scenario that the organism is monitored in real time by using mobile data traffic.

Description

technical field [0001] The invention relates to a video communication system and method for reducing transmission flow, and belongs to the technical field of video communication. Background technique [0002] With the development of social economy, mobile communication technology has been more and more widely used. In my country, although mobile communication technology started late, it has developed rapidly in recent years. In 2009, the Ministry of Industry and Information Technology issued mobile communication 3G licenses, and in 2013 the Ministry of Industry and Information Technology issued the first batch of mobile communication 4G licenses. The faster network speed increases the communication between people through video. With the development of video communication technology, there are more and more video communication between people, especially chatting through mobile phone video has become instant messaging. The common means of network development is from virtual t...
