Problems solved by technology

Because the information useful for traffic record requirements such as accident handling is often only tens of seconds before and after the accident, the rest of the information is redundant and does not need to be stored, which causes a serious waste of storage space
At the same time, the current driving recorder only simply records and stores road condition information, but cannot analyze the road condition information, and the value of the road condition information has not been brought into play

Embodiment 1

[0035] In ordinary road conditions such as urban roads, expressways, and hardened roads in counties and townships, the specific implementation methods are as follows:

[0036] Through the three cameras set, the road condition information in front of the vehicle is collected in real time and stored in the cache RAM. The ARM processor calls the road condition information in the cache RAM to match the system preset scene mode stored in the ROM, and press image 3 As shown, the conversion work status is explained in detail as follows:

[0037] (1) Matching judgment: when the matching degree between the real-time road condition information and the system preset scene mode is within a specified threshold range, the storage device is activated. When the real-time road condition information deviates from the system's preset scenario mode, and the degree of deviation exceeds the specified threshold range, the storage device is turned off and transferred to the real-time monitoring stat...

Embodiment 2

[0041] Application scenarios: For special groups such as car enthusiasts, adventure enthusiasts, and scientific expeditions, who often need to drive on special road conditions, they often need to record road condition information throughout the process, and are often very concerned about special road conditions such as mountain roads, deserts, muddy, and mountain peaks. Special records are required .

[0042] In view of the above situation, the specific implementation method is as follows:

[0043] Camera setup: install high-definition cameras on the edge of the front windshield of the vehicle, the front surfaces of the left rearview mirror and the right rearview mirror, and install a three-degree-of-freedom waterproof high-definition camera on the front section of the top of the vehicle.

[0044] Through the three cameras set, the road condition information in front of the vehicle is collected in real time and stored in the cache RAM. The ARM processor calls the road conditio...

Embodiment 3

[0049] The specific method of image scene matching: In this technical solution, various algorithms that can realize image scene semantic recognition can be used, such as scene semantic analysis algorithm PLSA, image pattern matching algorithm, etc. This example uses the Content Based Image Retrieval (CBIR) algorithm. Before use, the algorithm first establishes a feature library containing pictures of various preset scene modes. Use the MRSAR algorithm to extract the texture features of the picture in the preset scene mode to build the feature library 1, and use the HSV histogram algorithm to extract the color features of the picture in the preset scene mode to build the feature library 2. In each match, the image acquired in real time is first compared with the feature library 1, and the dimension of the feature library 2 is reduced according to the comparison result, and the simplified feature library 2 is used for a second comparison. The scenario pattern matching result ob...

Abstract

The invention discloses a real-time road condition information monitoring vehicle data recorder and a recording method for the same. The recorder consists of three web cameras, a high-definition camera, an information acquisition module, a real-time information processing and analysis module, a control module and a storage module. The recording method comprises the following steps that the information acquisition module acquires road condition image information in front of or on the side part of a vehicle through the web cameras and transmits the road condition image information to the real-time information processing and analysis module, the real-time information processing and analysis module performing analysis processing on the image information and transmits a result to the control module, and the control module controls the information acquisition module, the three web cameras, the high-definition camera, the real-time information processing and analysis module and the storage module according to the information processing result. According to the recorder and the recording method, redundant road condition information can be effectively removed, real-time monitoring and processing and selective storage can be realized, the storage space can be saved, and a running mode of the recorder can be automatically changed according to the analyzed information.

Description

technical field [0001] The invention relates to the field of video recording, in particular to an image processing technology-based real-time monitoring and recording device for road condition information and a recording method thereof. Background technique [0002] With the rapid increase of the number of urban motor vehicles, the road conditions are becoming more and more complicated, and traffic accidents are gradually increasing. Real-time captured traffic information is an important basis for judging responsibility for traffic accidents. At present, the road condition information recording equipment with the driving recorder as the main form intelligently and simply photographs the road conditions and continuously stores them in the storage device. Because the useful information for traffic record requirements such as accident handling is often only tens of seconds before and after the accident, the rest of the information is redundant and unnecessary to store, which c...
