Problems solved by technology
The resolution and frame rate of the image processed by the existing security video monitoring system are getting higher and higher, and the amount of information is quite huge. If it is not compressed, it will require hundreds of megabytes or even gigabytes of bandwidth, which will bring a huge burden to data storage, processing, and transmission. great inconvenience

Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.
[0021] The present invention considers that the existing security video monitoring system needs to store, process, and transmit huge data, and it is urgent to solve this problem with a high-speed compression method for large-resolution video images, so it provides a video image fast compression system and methods. The inventors have observed that video images have relatively large correlations and large amounts of data redundancy, and the correlation and statisti...

The present invention provides a video image rapid compression system and method. The system comprises a signal conversion unit, a control unit, a coding unit, a memory unit and an upper computer; the signal conversion unit converts an original image to a single-end image signal and sends the single-end image signal to the control unit; the control unit converts the single-end image signal to a RAW-format signal and sends the RAW-format signal to the coding unit; the coding unit encodes the RAW-format signal to generate a compression image signal and send the compression image signal to the control unit; the control unit receives the compression image signal and writes the compression image signal into the memory unit; and the upper computer accesses the memory unit to obtain the compression image signal. The video image rapid compression system and method are able to realize real-time acquisition of large-resolution video image, perform compression with high speed, high compression ratio and high resolution of a video image through adoption of the correlation and statistics characteristics of the image, and rapidly transmit the compression image to the upper computer and an external network.
Description
technical field [0001] The invention relates to the field of image processing, in particular to a video image fast compression system and method. Background technique [0002] With the development of science and technology, people pay more and more attention to public safety, and more and more security video surveillance systems have been applied. The security video monitoring system has gone through two stages of analog monitoring and digital monitoring. On the basis of digital monitoring, the new generation of monitoring technology is developing rapidly in the direction of large-scale network monitoring and intelligent monitoring. Therefore, the reliability of the security video monitoring system Performance, high resolution, intelligent video processing, management of 10,000 cameras, multiple video source signal input, network storage and other aspects pose more and more challenges. The resolution and frame rate of the image processed by the existing security video monit...
