Digital video recording method and device adopting dynamic compression ratio

Abstract

The invention discloses a digital video recording method and device adopting a dynamic compression ratio. The method comprises: S1, compression capacity obtaining: firstly, obtaining the remaining storage capacity of a monitoring camera in a detection system in real time through a storage capacity obtaining unit, sending capacity data to a processor through a feedback module after obtaining, sorting a plurality of compression ratios corresponding to the capacity data through a ratio obtaining unit, and then sending the compression ratios to a central processing system; and S2, video acquisition and preprocessing: detecting the inclination of the vehicle in the image of the monitoring camera through a gyroscope. The invention relates to the technical field of vehicle-mounted video monitoring. According to the digital video recording method and device adopting the dynamic compression ratio, automatic compression can be carried out according to the size of the recorded video, and the image is subjected to the steps of fidelity processing, size debugging and the like in the compression process, so that the definition of the video is enhanced, the recording duration of a vehicle-mountedvideo recording system can be effectively prolonged, and the video uploading pressure of a 4G network is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle video monitoring, in particular to a digital video recording method and device using a dynamic compression ratio. Background technique [0002] Through the vehicle monitoring system, you can know the location, speed, driving status and other information of the vehicle in real time, realize nearby dispatch, distress alarm and emergency alarm, understand the historical driving status of the vehicle, and analyze and count the working conditions of the vehicle, and form The construction of statistical reports and vehicle monitoring and dispatching system makes the management of vehicles more scientific and reasonable. While improving the management level, it also reduces a lot of unnecessary expenses. [0003] During the normal driving process of the vehicle, most of the monitoring data are monotonous and similar, without too high application value, and the recorded video is not high-resolution, and t...
