Among them, 1 is the main control chip, 2 is the gesture recognition module, 3 is the speech recognition module, 4 is the TTS module, 5 is the holographic projection display stand, 6 is the SD card, and 7 is the display screen.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Referring to Fig. 1, the holographic projection multimedia display platform based on voice and gesture control of the present invention includes a main control chip 1, an SD card 6, a holographic projection display stand 5, a TTS module 4, and a gesture recognition module for recognizing user gestures 2 and a speech recognition module 3 for recognizing speech, wherein the main control chip 1 is connected to the holographic projection display stand 5, the TTS module 4, the SD card 6, the gesture recognition module 2 and the speech recognition module 3.

The utility model also includes a display screen 7 connected with the main control chip 1; the speech recognition module 3 is connected with the main control chip 1 through the SPI bus; the gesture recognition module 2 is connected with the main control chip 1 through the IIC bus; the TTS module 4 Connect with the main control chip 1 through the serial port.

The model of main control chip 1 is STM32F407; the model of TTS module 4 is XFS5152CE; the model of speech recognition module 3 is LD3320; the model of gesture recognition module 2 is APDS9960.

Concrete work process of the present utility model is:

SD card 6 is pre-stored with some frequently asked questions and the answers to the questions, and the gesture recognition module 2 can identify the state of the user's hand moving up, down, left, right, close and far away, and then the user The movement state of the hand is sent to the main control chip 1, and the main control chip 1 generates a corresponding control command according to the movement state of the user's hand, and then controls the holographic projection display stand 5 to work according to the control command, wherein a movement of the user's hand The state corresponds to a control command; in addition, the speech recognition module 3 recognizes the voice information sent by the user, and then sends the user's voice information to the main control chip 1, and the main control chip 1 judges the type of the user's voice information. When the voice is a control command, the holographic projection display stand 5 is controlled to work; when the voice issued by the user is a voice problem, the TTS module 4 is used to answer the question raised by the user, wherein, in the judgment process of the main control chip 1 , the main control chip 1 searches the question answer in the SD card 6 according to the voice information sent by the user. The answer to the question is broadcast through the TTS module 4; when the answer to the question cannot be found, the recognized voice information of the user is a control instruction.
