Problems solved by technology

[0005] In recent years, many scholars at home and abroad have conducted a lot of research on the driver's driving behavior monitoring using image processing technology. However, most of the research is mainly focused on fatigue detection, through the driver's facial features such as gaze direction, facial expression, etc. However, this is only an indirect monitoring of the driver's driving behavior, and it is also easily affected by factors such as whether the driver wears glasses, the size of the driver's glasses, and facial differences, and the analysis of facial features is only an example of the driver's driving behavior. A small portion, ignoring the activity status of other parts of the driver's body

Abstract

The invention discloses a method for detecting an illegal driving behavior based on hand gesture tracking. The method comprises the following steps of: 1, reading an image from a monitoring video; 2, pre-processing the read image, and particularly performing gray conversion, image filtration, edge extraction, contour enhancement and the like; 3, positioning a steering wheel; 4, intercepting a corresponding interested area by using the steering wheel as the center; 5, extracting features of the intercepted area; and 6, classifying and identifying the extracted features, and judging whether hand gesture belongs to the illegal driving behavior. By the method, the illegal behavior of a driver in a driving period can be effectively determined, and a traffic accident which is caused by the illegal operation of the driver can be effectively avoided.

Description

technical field [0001] The invention relates to the field of traffic information control and driving behavior monitoring and early warning technology, in particular to a method for detecting driving violations based on hand posture tracking. Background technique [0002] In recent years, driving behavior monitoring and early warning technology has become one of the research focuses in the field of intelligent transportation. The situation is important. [0003] The current research on driving behavior monitoring and early warning technology can be roughly divided into the following categories: [0004] 1. A detection method based on sensing parameters of the driver's physiological state. This method evaluates the driver's driving state by measuring the driver's physiological signals. Physiological state sensing requires the driver to wear many instruments, which is difficult to apply in the actual driving process. 2. A sensor-based detection method for driving behavior ch...
