Traffic information collection and analysis system and operation method based on automobile data recorders

Abstract

The invention discloses a traffic information collection and analysis system and operation method based on automobile data recorders. The system comprises a plurality of automobile data recorders, andeach automobile data recorder comprise a front-end data acquisition module and a mobile communication module, wherein the front-end data acquisition module is connected with a storage module and a central processor, and obtains video data from the storage module and the central processor, and processes the video data through a data mining algorithm to form image structuralized data. Each mobile communication module transmits the image structuralized data to a background image analysis module, and the background image analysis module performs the image secondary recognition and structuralizeddata preprocessing of the image structuralized data, and then classifies the processed structure and transmits the processed structure to the corresponding mechanism for deep processing. The system effectively employs the video image resources collected by the automobile data recorders, achieves the vehicle density analysis, road condition information collection and municipal administration construction and positioning. The system achieves the positioning, recognition and monitoring of the transportation infrastructure through the captured road condition information.

Description

technical field [0001] The invention relates to the technical field of traffic data collection and analysis, in particular to a traffic data collection and analysis system and operating method based on a driving recorder. Background technique [0002] The functions of the existing driving recorder have been relatively comprehensive. It can be said that the car uses a black box, and the display control host in the car obtains video information from the camera device, and performs image processing on the video information for display and storage. [0003] However, the stored video is only used to provide evidence for traffic accidents to protect the driver's self-rights or for self-driving tours to record beautiful moments. When the memory occupied by the stored video is greater than a certain limit, the driving recorder will delete the video by time according to the deletion strategy. Therefore, the potential value of the stored video has not been excavated in an all-round wa...

AI Technical Summary

Problems solved by technology

When the memory occupied by the stored video is greater than a certain limit, the driving recorder will delete the video by time according to the deletion strategy. Therefore, the potential value of the stored video is not fully excavated, which is a waste of data resources to a certain extent.
