Driving behavior comprehensive evaluation system and method

Abstract

The invention relates to a driving behavior comprehensive evaluation system and method. The system comprises a video information acquisition unit, a video information storage unit, a video information processing unit, an evaluation information acquisition unit, an evaluation information processing unit and a comprehensive information management unit. A driver-pedestrian-based evaluation mechanism is constructed, so that the system can conduct real-time evaluation and caution on the driving behavior of a driver through evaluation criterions extracted according to information characteristics of a monocular video and the like, and evaluative feedbacks from vehicles and the pedestrians related to the driver can be conducted on the driving behavior of the driver through the mechanism of the system, and the evaluation of each driver is from accumulation of system evaluation and public evaluation in the practical driving process. The driving behavior comprehensive evaluation system provides a feedback channel for bad driving habits of the driver, and is favorable for establishing a safe and standard driving environment. In addition, only monocular video acquisition information of a single camera is utilized, so that required hardware is simple and easy to achieve.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and relates to a driving behavior comprehensive evaluation system and method. Background technique [0002] At present, the driver automatic evaluation model based on fuzzy evaluation is only used in the driving test process in some areas, because the test process is relatively simple and fixed, and the links are easy to quantify, so the driver evaluation model is relatively simple and easy to implement. However, its evaluation index only considers whether the driving behavior violates the rules or not, and does not take into account more complicated situations, so it is not suitable for the usual evaluation of drivers. The patent with the application number CN201210567491.9 discloses a dangerous driving behavior correction and evaluation technology for automobile drivers, which involves a dangerous driving behavior correction and evaluation system for automobile drivers.

Problems solved by technology

This method is based on an expert system, and the defined dangerous driving behavior is mainly centered on the evaluated driver, without more consideration of the existence of bad driving behavior, that is, the driving behavior may not be dangerous to the driver and the vehicle itself. Or the level of danger is very low. Although it did not directly cause an accident, it has a bad influence on other drivers or pedestrians and even becomes a serious hidden danger of accidents caused by danger.

For example, overtaking and grabbing lanes, merging without prompting, not giving way to pedestrians, etc., these behaviors are difficult to be discovered by the regulatory authorities in time and given corresponding warnings or penalties
