Vehicle-mounted monitoring device, monitoring system based on expression recognition, and monitoring method

Abstract

The invention relates to a vehicle-mounted monitoring device, a monitoring system based on expression recognition, and a monitoring method. The vehicle-mounted monitoring device is good in concealment, large in monitoring visual field and good in monitoring effect. According to the monitoring system and method based on expression recognition, real-time monitoring of the mobile terminal can be achieved, monitoring data are not prone to being lost, and control operation of the monitoring device in the vehicle can be achieved through the mobile terminal. Face detection and suspicious expression recognition are based on a deep learning algorithm training expression recognition model, a potential infringement object can be automatically recognized, and the recognition accuracy is high. Comparedwith other algorithms, the Adaboost face position detection model has better calculation efficiency and is suitable for the requirement of real-time operation. Compared with the traditional CNN for classifying expressions, the LSTM network capable of ensuring the time sequence is used, the LSTM network focuses on continuous expression changes, the detection result of each frame can influence thenext frame, and a suspicious expression judgment result can be output at each moment, so the suspicious expression judgment reliability and the alarm timeliness are improved.

Description

technical field [0001] The invention belongs to the field of security protection, and in particular relates to a vehicle-mounted monitoring device, a monitoring system and a monitoring method based on facial expression recognition. Background technique [0002] The traditional on-board monitoring device is easy to block the line of sight after installation, and the shooting field of view is small, so it is impossible to monitor the car and the internal and external conditions in an all-round way. In addition, there are also problems of abrupt appearance, poor concealment, and easy discovery and destruction by criminals. With the increase of the number of cars in our country, the number of criminal cases related to vehicle damage and theft is increasing, which seriously threatens people's property safety. Based on this, people are in urgent need of a vehicle-mounted monitoring device with better concealment and monitoring effect. Contents of the invention [0003] The inv...
