Low-bit-rate video code transmission reconstruction method and system

Abstract

The invention discloses a low-bit-rate video code transmission reconstruction method and system. The low-bit-rate video code transmission reconstruction method includes the following steps that original video images of a monitoring region are acquired; the characteristics of the original video images are extracted, the extracted characteristics of the video images are vectorized, so that vectorized characteristic information of the original video images is acquired; the vectorized characteristic information is transmitted through a wireless network; image reconstruction is conducted on the vectorized characteristic information, and then simplified images corresponding to the original video images are acquired. According to the method, the high frame rate is kept, the data rate of transmission of the original video images can be greatly decreased, data can be transmitted on the wireless network with the extremely low bit rate, due to the fact that the vectorized characteristic information is small and the occupied bandwidth is small, high-frame-rate videos can be continuously transmitted in the extremely-narrow bandwidth environment, delay-free monitoring is achieved, and high anti-interference characteristics are achieved.

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 ...
