Problems solved by technology

[0002] There is a difficulty in speech recognition, that is, the sound collection device cannot judge when the user is chatting with other objects, and when the user is giving commands to the voice system. It is a lot of inconvenience, and since you have to press the button, in the scene where the operation steps are simple, it is a bit redundant to give the voice command, just make a different button and press it

Embodiment Construction

[0043] Please check figure 1 , an apparatus for issuing voice commands based on eye contact, comprising at least one voice collector 1, a first camera 7, a first analyzer 8, at least one automatic pan-tilt 4 equipped with a second camera 2 and a light emitter 3 , a second analyzer 5 and a controller 6. The first camera 7 is a wide-angle camera 7, as required, other cameras can also be used, such as ordinary cameras, and the first analyzer 8 is a wide-angle image acquisition analyzer 8, if other cameras are used, ordinary images can be used instead Acquisition analyzer; the second camera 2 is a long zoom camera 2, as required, other cameras can also be used, such as common cameras, and the second analyzer 3 is a telephoto image acquisition analyzer 3, if other cameras are used, corresponding Ordinary image acquisition analyzer can be used instead. The light emitted by the light emitter 3 is light that can be captured by the camera and is not irritating to human eyes, such as ...

Abstract

The invention discloses a sight connection-based voice command issuing device and method. The sight connection-based voice command issuing method comprises steps of 11, capturing and shooting to obtain first video data; 12, analyzing first video data and judging whether a face is toward a first camera and continuously stays for t1 or not, obtaining azimuth information and executing a step 2 if yes and continuously executing the step 11 if no; 2, adjusting a second camera according to the azimuth information, enabling the second camera to shoot the face to obtain second video data, and controlling a light transmitter to transmit light to human eyes so as to obtain reflective images of the human eyes; 3, analyzing second video data to obtain real-time three-dimensional coordinates of the face and judging whether the human eyes stare the cameras or not according to human eye images and the reflective images and positions; 4, judging whether the human eye stare time exceeds t2 or not, identifying sight connection and sending a command to a corresponding voice collector if yes; 5, enabling the voice collector to collect voice, identifying voice to obtain semantic contents, providing the semantic contents for other devices to access, judging whether a conversion is finished or not, executing the step 1 if yes and ignoring the face relevant information in the first video data during the conversion if not.

Description

technical field [0001] The invention relates to a device and method for issuing voice commands based on eye contact. Background technique [0002] There is a difficulty in speech recognition, that is, the sound collection device cannot judge when the user is chatting with other objects, and when the user is giving commands to the voice system. It is a lot of inconvenience, and since you have to press the button, in the scene where the operation steps are simple, it is a bit redundant to issue a voice command, just make a different button to press. Contents of the invention [0003] The present invention provides a voice command issuing device and method based on gaze connection, which overcomes the shortcomings of the voice command issuing device and method in the background art. [0004] One of the adopted technical schemes that the present invention solves its technical problem is: [0005] The device for issuing voice commands based on eye contact includes at least on...
