Problems solved by technology

However, whether this solution can avoid danger depends mainly on the reaction speed of the driver or the vehicle. Even if the pedestrian is warned, it is based on the vehicle's angle to judge that there may be danger before the driver honks the horn or automatically honks the horn. Alarms are issued in different ways. Due to the high speed of the vehicles, the alarms at this time are often unable to avoid the occurrence of danger in time.
In general, the existing technology lacks an effective technical solution for hazard warning based on pedestrian state analysis

Embodiment Construction

[0046] method embodiment

[0047] refer to figure 1 , the present invention provides a method for real-time analysis of pedestrian status based on mobile devices, comprising the following steps:

[0048] After obtaining the real-time physiological signal of the pedestrian, according to the change of the physiological signal, analyze and obtain the fatigue level of the pedestrian;

[0049] Interference detection is performed based on the inertial sensing signal IMU signal of the mobile device, and the interference status of the mobile device to pedestrians is judged;

[0050] When it is judged that the pedestrian is in the area where the motor vehicle appears, based on the interference detection result and the fatigue level of the pedestrian, it is judged to obtain the danger level of the pedestrian;

[0051] According to the obtained danger level, corresponding warnings are given to pedestrians.

[0052] The present invention acquires the real-time physiological signal of t...

Abstract

The invention discloses a real-time analysis method and system for the pedestrian state based on mobile equipment. According to the invention, a real-time physiological signal of a pedestrian is obtained, the fatigue level of the pedestrian is obtained through analyzing changes of the physiological signal, and the interference state of the mobile equipment for the pedestrian is judged based on anIMU (Inertial Measurement Unit) signal of the mobile equipment, so that the risk level of the pedestrian can be obtained when the pedestrian is in an area where a motor vehicle appears, and the pedestrian is correspondingly warned and reminded timely and quickly. The real-time analysis method and system perform analysis from the perspective of the pedestrians, thereby being capable of warning thepedestrians automatically and timely when a danger is judged to occur, enabling the pedestrians to avoid the danger timely, and being capable of widely applied to the pedestrian safety monitoring industry.

Description

technical field [0001] The invention relates to the field of pedestrian safety monitoring, in particular to a mobile device-based real-time analysis method and system for pedestrian status. Background technique [0002] In the field of car safety driving, how to improve the safety of vulnerable road users is an important issue. In the current technology, safety warning is mainly based on the perspective of the driver, such as judging the proximity of the vehicle through data collected by sensors such as image acquisition. Whether there are pedestrians, so as to give an alarm, etc., or by collecting the physiological state of the driver, so as to judge whether the driver is driving in fatigue, so as to realize the corresponding safety warning. Generally speaking, in the prior art, it is mainly based on monitoring the vehicle side to realize safe driving and avoid causing danger to pedestrians. However, whether this solution can avoid danger depends mainly on the reaction spe...
