Embodiment 1

[0025] In this embodiment, a method for building a safety belt recognition model is provided, figure 1 is a flow chart of a method for building a seat belt recognition model according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0026] Step S101: collecting head and shoulder region images. At present, most cars are equipped with a front-facing camera that records driving conditions. This camera can collect images of the overall area where the driver and co-driver are located, and can clearly capture the driver without affecting the driving safety of the driver. state of behavior;

[0027] Step S102: Obtain a training set of wearing a seat belt and a training set of not wearing a seat belt according to the image of the head and shoulder region. In order to adapt to various complex environments, collect 100,000 sample images of drivers wearing seat belts and 100,000 sample images of drivers not wearing seat ...

Abstract

The invention provides a safety belt identification model establishing method and device. The safety belt identification model establishing method comprises the steps that a head-shoulder zone image is acquired, fastened safety belt training sets and un-fastened safety belts training set are obtained according to the head-shoulder zone, positive sample characteristics are determined according to the fastened safety belt training sets, negative sample characteristics are determined according to the un-fastened safety belt training sets, and a safety belt identification model is obtained by utilizing positive sample characteristic and negative sample characteristic training classifiers. The problem that the un-fastened safety belt behavior detection accuracy rate is low in the prior art is solved, establishment of the safety belt identification model is achieved, and the un-fastened safety belt behavior detection accuracy rate is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and device for constructing a safety belt identification model. Background technique [0002] Intelligent transportation system is the development direction of the future transportation system, and it is also a frontier research topic in the field of transportation in the world. Car accident surveys show that if you wear a seat belt in a frontal collision, the death rate can be reduced by 57%, in a side collision by 44%, and in a rollover by 80%. Therefore, how to effectively supervise whether the driver is wearing a seat belt and promote the driver to consciously develop the habit of safe and civilized driving, so as to ultimately reduce casualties in traffic accidents is a meaningful topic. In recent years, the intelligent transportation system based on image processing technology has been widely used, but it still faces many difficulties to analyze...
