In this embodiment, key points of a face may be selected from an image to form a plane graph, and the plane graph is calculated and analyzed to obtain a face yaw angle, it can be understood that a manner of calculating the face yaw angle may be selected according to actual needs, a specific manner of calculating the face yaw angle is not limited in this embodiment, and a process of calculating the face yaw angle in different manners is well documented in the existing literature and is not described in this embodiment.
After the face yaw angle is obtained, whether the face yaw angle meets a preset angle condition is further judged, so that whether the face faces the ticket vending machine is judged, if the face yaw angle meets the preset angle condition, the face faces the ticket vending machine, the face which meets the distance condition and the angle condition is determined to be a first face, and if the face which meets the angle condition does not meet the preset angle condition, the first face which meets the preset condition does not exist. It is understood that if the first face exists, the number of the first faces is at least one.
On the basis of the above embodiment, the distance condition includes a first distance condition and a second distance condition.
Accordingly, the specific process of determining whether the distance satisfies the preset distance condition in step 1012 is executed in steps 10121-10122, and the specific process includes:
step 10121, calculating a first distance between the face and a plane where the front face of the ticket vending machine is located, and calculating a second distance between the face and a plane where the side face of the ticket vending machine is located.

And 103, starting a microphone to enable the microphone to receive a voice ticket purchasing instruction of the target passenger, and sending the voice ticket purchasing instruction to the server to receive the ticket drawing information returned by the server.
After the ticket vending machine is awakened, a microphone on the ticket vending machine is started, the voice ticket purchasing instruction of the target passenger is received through the microphone, then the voice ticket purchasing instruction received by the microphone is sent to the server, the server analyzes the voice ticket purchasing instruction, payment of the fare is completed, ticket outlet information is generated, and finally the server sends the ticket outlet information to the ticket vending machine interaction equipment.
In one embodiment, the ticket vending machine further comprises a display module.
Correspondingly, the specific process of sending the voice ticket purchasing instruction to the server in step 103 to receive the ticket drawing information returned by the server is executed in step 1031, and specifically is as follows:
step 1031, sending the voice ticket buying instruction to a server so that the server performs character conversion and voice feature recognition on the voice ticket buying instruction to obtain ticket buying information and voice features; and sending the ticket buying information fed back by the server to a display module for display, acquiring a voice confirmation instruction received by a microphone, sending the voice confirmation instruction to the server so that the server completes fare payment according to the voice characteristics and the ticket buying information and generates ticket drawing information, and receiving the ticket drawing information returned by the server.
After the voice ticket buying instruction received by the microphone is sent to the server, the server performs character recognition and voice feature recognition on the voice ticket buying instruction, and the purpose of performing character recognition on the voice ticket buying instruction is to convert the voice ticket buying instruction into characters so as to obtain the meaning of the voice ticket selling instruction, thereby obtaining ticket buying information. The voice feature recognition aims to recognize voice features in the voice ticket buying instruction, and each user can be understood to have different voice features. In this embodiment, different neural networks trained in the prior art may be respectively used to implement text recognition and speech feature recognition, and the specific structure and training process of the neural network are well documented in the existing literature and are not described in detail in this embodiment.
The method comprises the steps that after a voice ticket purchasing instruction is subjected to character conversion by a server to obtain ticket purchasing information, the ticket purchasing information is sent to a ticket vending machine, the ticket purchasing information is sent to a display module by the ticket vending machine to be displayed, the display module displays a word of 'please confirm by voice of a passenger' on the display module while displaying the ticket purchasing information, the passenger sends a voice confirmation instruction, then obtains the received voice confirmation instruction from a microphone and sends the voice confirmation instruction to the server, the server determines whether the target passenger confirms the ticket purchasing according to the voice confirmation instruction after receiving the voice confirmation instruction, if yes, determines a corresponding payment account according to voice characteristics, finishes fare payment according to the ticket purchasing information and generates ticket discharging information, and feeds the ticket discharging information back to ticket vending machine interaction equipment.
