If a person enters the sensing range of the elevator box body 1, a high level is output, if the person leaves the sensing range, the high level is automatically delayed and closed, a low level is output, and the OUT pin of the module is connected with the pin in the raspberry group, so that whether the person exists in the subway can be known only by detecting whether the input voltage of the pin is the high level or the low level.
In order to enable old users to select floors by directly using face recognition, the features of faces of the old users must be stored, an LBDH algorithm is adopted as an algorithm for extracting the features of the faces, and from the viewpoint of texture analysis, the algorithm is used for judging the texture features of a certain pixel point on an image, namely the relationship between the point and a walking pixel point and the relationship between the point and a point in the field of the old users. From which angle the features are extracted for this relationship, different kinds of features are formed. Good features, can be classified according to texture. LBPH constructs a relationship that measures one pixel and its surrounding pixels.
The specific operation is as follows:
1. and finding out the positions of all the detected faces in the picture by using Haar.
2. And calculating 68 characteristic points of the face, and properly adjusting the position of the face to align the face.
3. The face image obtained in the previous step is put into a neural network, 128 feature measurement values are obtained, and they are stored.
4. And calculating the Euclidean distance together with the previously stored measured values to obtain the Euclidean distance value, and comparing the values to obtain whether the same person exists or not.
The equation for obtaining the euclidean distance value is:
inputting voice: because the raspberry group is not provided with a voice input module, the functions of the raspberry group can be realized only by converting a sound card into a USB, then the sound card is connected into a USB port of the raspberry group, and then the microphone 9 is connected into the sound card to finish the hardware for voice input of the raspberry group.
And (3) voice recognition: the recognition of the voice is realized by a message flying SDK, the solution is to log in an API of the message flying, then an interface XF _ text (file, audio _ rate) of the API is used, wherein the file is the address stored in the audio file, the audio _ rate is the audio frequency which is generally 16000, the voice can be converted into characters by using the function, the MFCC characteristics of the voice are extracted, and then comparison is carried out to obtain a command instruction, and the recognition rate can reach 96%.
And (3) playing voice: the language for playing the information of the floor and the information of the upstairs and downstairs is realized by an ilangdb packet, and the desired voice can be played by calling an ilang function. Because the raspberry pi has a 3.5mm audio output port, the connection with the loudspeaker 8 can be completed directly.
A face recognition module, namely a camera 10, is added in the elevator, the use method is that a user firstly carries out face recognition, if the passenger is an old user, the face of the old user can be directly recognized to obtain the floor number of the old user, the floor number selection can be finished, and if the old user goes to other floor numbers or a new passenger is used, the voice recognition is directly carried out. The mechanism can greatly improve the convenience of contactless riding, and the flow of the face recognition of the device is shown in figure 3.
