Embodiment 1

[0030] figure 1 It shows a flow chart of an interactive method for robot spatial positioning provided by an embodiment of the present invention, which is described in detail as follows:

[0031] In step S101, the voice command is acquired in real time, and the sound source direction of the voice in the voice command is acquired according to the microphone array algorithm.

[0032] Specifically, in the embodiment of the present invention, the robot performs recording through the system, controls the microphone array to pick up voice in real time in all directions while recording, receives voice commands, and then obtains the direction of the sound source through the microphone array algorithm. A single microphone can only obtain sound information, while a microphone array composed of multiple microphones placed in a certain geometric position can obtain not only sound information but also spatial information of sound.

[0033] Optionally, in order to avoid interference and sav...

Embodiment 2

[0100] image 3 A flow chart showing another interactive method for robot spatial positioning provided by an embodiment of the present invention is described in detail as follows:

[0101] In step S201, the voice command is acquired in real time, and the sound source direction of the voice in the voice command is acquired according to the microphone array algorithm.

[0102] In this embodiment, for the specific steps of step S201, refer to step S101 of the first embodiment, which will not be repeated here.

[0103] Step S202, judging whether the voice command is noise according to the sound characteristics of the voice command.

[0104] Specifically, in the embodiment of the present invention, the microphone array picks up speech in all directions, and the omnidirectional direction may be 360 ​​degrees in the horizontal direction or 360 degrees in the vertical direction. The voice instruction includes sound signals from various sound source directions, so the received voice ...

Embodiment 3

[0115] Corresponding to the interactive method of robot spatial positioning described in the above embodiments, Figure 4 It shows a structural block diagram of an interactive device for robot spatial positioning provided by an embodiment of the present invention, the device can be applied to a smart terminal, and the smart terminal can include user equipment that communicates with one or more core networks via a radio access network RAN , the user equipment may be a computer with a mobile device, for example, an intelligent robot. For ease of description, only parts related to the embodiments of the present invention are shown.

[0116] refer to Figure 4 , the interaction device for spatial positioning of the robot includes: a direction acquisition unit 31, a user locking unit 32, a position calculation unit 33, and an operation execution unit 34, wherein:

[0117] The direction obtaining unit 31 is used to obtain the voice instruction in real time, and obtain the sound so...

Abstract

The present invention provides an interaction method and a device of robot space positioning, pertaining to the technical field of terminals. The method comprises the following steps: acquiring a voice command in real time, and acquiring sound source direction of the voice in the voice command according to a microphone array algorithm; acquiring image information of the sound source direction, andlocking a command user based on the image information of the sound source direction; calculating position information of the locked command user; and adjusting the position information of a robot according to the position information of the command user, and performing the operation corresponding to the voice command. According to the method, the specific location of the user sending the commandcan be positioned accurately, and the efficiency of performing the user command is improved.

Description

technical field [0001] The invention belongs to the technical field of terminals, and in particular relates to an interactive method and device for spatial positioning of a robot. Background technique [0002] With the development of social productivity and the advancement of multimedia processing technology, people have higher and higher requirements for robot functions, expecting robots to be able to "listen", "see" and "move". In practical applications, robots often need to interact with humans through voice and operation, and how the robot locates and instructs the user has become a difficult problem. [0003] In the existing technology, the auditory function of the robot can be realized through the sound source localization technology, so as to locate the position of the commanding person. Specifically, the sound source localization technology is to collect sound signals through a microphone array with a certain geometric relationship, and estimate it through digital si...
