Problems solved by technology

If we only emphasize on ensuring the frame rate of the video, then in a low-rate wireless channel environment, the quality of each frame of video image will inevitably be reduced, and a harmful "Mosaic" effect will be produced.

Embodiment Construction

[0007] 1. Design and implement a fast vision-centered filtering algorithm to allocate more codewords to macroblocks near the user's attention point in real time, and allocate less codewords to other macroblocks to achieve In a low-speed wireless communication environment, better monitoring image effects are obtained;

[0008] 2. Design and implement a real-time self-adaptive variable frame rate encoding algorithm, which can automatically encode the slow-moving shots at a lower frame rate, and for the violently moving shots, encode at a higher frame rate The purpose is to save precious video code streams for video error control on the premise of ensuring the visual quality of the video, so as to ensure the visual quality of the surveillance image as much as possible;

[0009] 3. Design and implement a video digital watermark algorithm that can be used for video content security authentication and error control. This watermark algorithm improves the security of the monitoring sy...

Abstract

Disclosed is a mobile video monitoring system based on visual sense quality. Through fully tapping the characteristics of a human body visual sense model, by use of a wireless communication technology, self-adaptive variable frame rate encoding and content safety authentication, video data acquired in real time at a monitored point is compressed and encoded and then is transmitted to a monitoring center through a flow-type transmission mode, and under the condition of a low-rate high-error code wireless channel environment, the visual sense quality of a video monitoring image is ensured as much as possible and the safety of video communication is improved. The system provided by the invention has the remarkable advantages of convenient installation, rapid coverage, high flexibility, high expansibility, wide coverage scope, good mobility, high anti-interference and anti-fading capabilities, excellent stability and reliability, and the like.

Description

technical field [0001] The invention relates to the communication field, in particular to a mobile video monitoring system based on visual quality. Background technique [0002] With the continuous improvement of the degree of social informatization, the range of wireless video surveillance that needs to be implemented in all walks of life in society has increased rapidly. In addition, the narrow-band and high-noise characteristics of wireless networks are "powerless" for streaming video services that require continuous and large bandwidth. Therefore, improving the visual quality of surveillance images in mobile video communications has become an important topic in contemporary social research. [0003] The 11.15 catastrophic fire accident in Shanghai once again sounded the alarm for the fire protection of high-rise buildings in China. At present, the main means in the world to solve the fire-fighting problems of high-rise buildings is to use ladders or fire-fight...
