A low-bit-rate video coding transmission reconstruction method and system

Abstract

The invention discloses a method and system for reconstruction of low-bit-rate video encoding and transmission. The method includes the following steps: collecting original video images in a monitoring area; performing feature extraction on the original video images, and extracting features of the video images after feature extraction. performing vectorization to obtain the vectorization feature information of the original video image; transmitting the vectorization feature information through a wireless network; performing image reconstruction on the vectorization feature information to obtain a simplified version corresponding to the original video image image. While maintaining a high frame rate, this method can greatly reduce the data rate of transmitting the original video image, so that it can be transmitted on a wireless network with a very low bit rate. Since the vectorized feature information is extremely small, the bandwidth occupied is extremely small. Small, it can realize uninterrupted transmission of high frame rate video in an extremely narrow bandwidth environment, so as to achieve the purpose of monitoring without delay, and has strong anti-interference characteristics.

Description

technical field [0001] The present invention relates to the field of video transmission, in particular to a method and system for reconfiguring low-bit-rate video coding and transmission. Background technique [0002] Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. It shoots specific scenes through cameras and transmits them to display devices for display. In occasions where video transmission without delay is required, such as in remote Monitor the external video of the environment where the high-speed driving car, aircraft or robot is located, and remotely control the driving trajectory of the car, aircraft or robot, capture the target, etc. according to the monitored external video, due to the network environment during the video transmission process Or the limitation of bandwidth, it is difficult to realize the transmission of the collected video without delay, and the bandwidth occupied in ...
