the passenger P scans the two-dimensional code at the bus station through the mobile phone terminal to select 88 buses to be arrived for prepayment, at the moment, the weight of the passenger P is recorded to be 80.23kg, the footprint of the passenger P is recorded to be J-shaped, and the data is sent to the 88 buses to be arrived;
the checking module of the 88-way bus which is about to arrive at the station collects 1000 groups of historical data according to a formula:
calculating to obtain the maximum error increment of 0.37kg;
calculating to obtain the maximum error reduction amount of 0.32kg;
at this time, the passenger P sweats a lot because the weather is too hot at the platform; when an 88-way bus arrives and passes the verification, the current weight is 80kg and is within the error allowable range, so that the footprint verification is carried out;
according to the formula:
the obtained similarity is 95%, and the similarity threshold is 88%, so that the verification is successful, the indicator light flickers, and the passenger P can get on the vehicle directly.
After getting on the bus, the gaze detection module detects an initial included angle of the gaze of the passenger P and the sensor module, which is 45 degrees; then the pupil deflects, and the included angle between the pupil and the sensor module is 60 degrees when the gaze leaves the stop board; the straight line distance between the stop board and the stop board is 1.5m;
according to the formula:
thus 0.63m backwards from the first station, which was found to be the twelfth station "white horse park station"; it is thus predicted that the passenger P gets off at the "lima park station".
The working principle of the invention is as follows: the invention utilizes the prepayment module to lead passengers to pay in advance when waiting for the bus, thus ensuring the order of getting on the bus; the information of the pre-paid passengers is transmitted to the buses of the corresponding bus numbers by utilizing a communication module; verifying the identity of the pre-paid passenger by using a verification module, setting an error range and ensuring the verification accuracy; tracking the pupil deflection angle of the passenger by using a sight detection module to obtain the path of the passenger watching the stop board and predicting the platform for getting off; informing a driver of a departure result by using an output module to prepare the driver; reporting platforms with more passengers for getting off by using a reminding module, and setting the minimum opening time of a getting-off door; utilize alarm module to give an alarm to the passenger who loses the article and inform when it has not got off the bus yet, guarantee passenger's property safety, reduced the trouble that the article was lost in passenger's follow-up searching simultaneously.
