Multi-sensor monitoring device and monitoring method

Abstract

The invention discloses a multi-sensor monitoring device, comprising: a target detection device, an image acquisition device, a target recognition device, a processing device and a power supply device. The invention also discloses a multi-sensor monitoring method, including: detecting the target approaching the vehicle, judging whether the target is a valid target, ignoring the non-valid target, and entering the next step for the valid target. The environment image is collected, and the image information of effective targets is extracted from the environment image. Obtain the physical characteristics and moving trajectory of the effective target, and identify the effective target according to the physical characteristics and moving trajectory. Carry out data fusion to generate valid target recognition results, image data, physical characteristics and moving trajectories. Carry out data storage, save the original data of effective targets and the recognition results, image data, physical characteristics and moving tracks of effective targets generated by data fusion.

Description

technical field [0001] The invention relates to the technical field of automobile safety, more specifically, to the technical field of monitoring the surrounding environment of automobiles. Background technique [0002] With the advancement and development of intelligent driving and artificial intelligence technology, people's demand for vehicle monitoring systems continues to increase. Especially for situations such as collisions and scratches that occur after the process of parking the vehicle, if there is no perfect solution, certain economic losses and unnecessary troubles may be caused. [0003] In the existing vehicle monitoring systems and methods, they are mainly divided into three categories: [0004] 1) Most of the vehicle-mounted driving recorders in the market are fixed on the front windshield of the vehicle by using a camera sensor to detect the environment in front of the vehicle. The characteristics and limitations of this method are: the driving recorder ma...

AI Technical Summary

Problems solved by technology

The characteristics and limitations of this method are: the driving recorder mainly records the driving state, and mainly pays attention to the conditions of the road ahead or the road behind during driving

The characteristics and limitations of this method are: this method uses the on-board battery as the power source, can continue to work after the vehicle is parked and turned off, and monitors the surrounding status through sensors

Although the third type of monitoring equipment performs light sensing and supplementary light to solve the problem of dim light, the processing method of this type of monitoring equipment is only a simple record of data without further processing

In the process of use, the existing problems are as follows: on the one hand, it is easy to cause false alarms, such as when the vehicle is parked too close to some fixed obstacles, or when there is a non-motorized vehicle parked next to the vehicle, it is easy to trigger false alarms

On the other hand, when encountering an infringement situation, the camera is simply turned on to record the situation within the field of view

If the field of view of the camera is small and the infringing target is not within the field of view, relevant information cannot be obtained

If the infringing target leaves the field of view of the camera, it will not be able to continue to obtain images, resulting in incomplete information

In addition, when there is an infringement, there are multiple targets in the field of view of the camera. At this time, the multiple targets will not be distinguished and identified, which will cause difficulties in the later processing.
