Reminding system and method for non-wearing of safety belt

Abstract

The invention relates to the field of automobile parts and components, in particular to an auxiliary system and method for a safety belt. A reminding system for non-wearing of the safety belt comprises a camera, an image recognition and control assembly, the safety belt and an alarm device. A two-dimension code recognition pattern indicating that the safety belt is worn is arranged on the safety belt. The output end of the camera is connected to the input end of the image recognition and control assembly. The image recognition and control assembly is connected with the alarm device in a control mode. A reminding method for non-wearing of the safety belt comprises the steps that an image to be analyzed is obtained, face recognition and judgment are conducted, two-dimensional code scanning and judgment are conducted, and whether an alarm is given or not is determined according to a code scanning result. According to the reminding system and method for non-wearing of the safety belt, the image photographed by the camera is analyzed and processed, and whether a person exists or not and whether the safety belt is worn or not under the condition that the person exists are recognized; only one camera needs to be additionally arranged in the aspect of hardware equipment, and thus the arrangement of internal decoration of an automobile is prevented from being influenced; and the alarm reliability is high, the false alarm / alarm omission rate is quite low, the safety of passengers is guaranteed, and the reminding system and method have high application value and popularization value.

Description

technical field [0001] The invention relates to the field of vehicle components, in particular to a safety belt accessory system and method. Background technique [0002] At present, the existing seat belt unfastened reminder device is to judge whether the seat belt is inserted into the buckle through the sensor on the seat belt buckle through the pressure sensor installed on the seat to identify whether there is someone on the seat. Are the occupants wearing seat belts? This way of judging has two problems: 1. If the plug-in piece imitating the safety belt lock tongue is used, the existing device can be easily deceived, causing the failure of the safety belt reminder function; 2. When a certain weight is placed on the seat After the item is mistakenly identified as someone in the seat, it is reminded to wear a seat belt. Therefore, the recognition ability is very poor, there are many false positives, and the practical value is low. Contents of the invention [0003] Th...
