Embodiment Construction

[0094] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0095]The H.264 encoding process includes five parts: inter-frame and intra-frame prediction, transformation and inverse transformation, quantization and inverse quantization, loop filtering, and entropy coding. Inter-frame predictive coding exploits temporal redundancy in successive frames for motion estimation and compensation. The motion compensation of H.264 supports most of the key features in previous video coding standards, and adds more functions flexibly. In addition to supporting P frames and B frames, H.264 also supports a new inter-stream transmission frame - SP frame. After the code stream contains SP frames, it can quickly switch between code streams with similar content but different bit rates, and supports random access and fast playback modes; intra-frame coding is used to reduce the spatial redundancy of images. In order to improve t...

Abstract

The invention discloses a vehicle security risk warning and accident reconstruction system and method of big data processing. The system comprises a vehicle-mounted video terminal and a cloud big data processing platform, all kinds of parameters, video images, voice information and the like of vehicle operation are analyzed by the big data processing platform in the background to provide effective information for accident authentication, driving behaviors of drivers, vehicle conditions and the like, and provide a novel method for confirmation of responsibility, vehicle improvement, traffic management and the like. The system is a research and development system of a key common technology based on cloud computing, collected videos are encoded in an H.264 manner, stored locally and are circularly covered, and after an abnormal driving behavior is detected, video data within 10-30 seconds before and after the time point are transmitted to a service system for accident analysis and reconstruction. The system solves the vehicle driving security risk problem and provides a vehicle security public service platform.

Description

technical field [0001] The invention relates to a vehicle safety hidden danger early warning and accident reappearance system and method for big data processing. Background technique [0002] With the continuous development of the automobile industry, the number of automobiles in my country continues to rise, and the traffic accidents that follow have become a major social nuisance. The World Health Organization stated on May 6 that more than 200,000 people die in road traffic accidents every year in China. Schwartländer, the representative of the World Health Organization in China, published an article in the "China Daily" that a large number of road traffic accident deaths "are completely avoidable." Therefore, the analysis and research on traffic accidents can obtain the causes of traffic accidents and the causes of personal injuries, and then take measures to reduce the occurrence of traffic accidents or the personal injuries caused by accidents. [0003] With the evol...
