In this embodiment, in order to improve user experience, the virtual robot generates a virtual portrait through a holographic projection technology to interact with a user, the virtual portrait is preferably a three-dimensional image generated through the holographic projection technology, and the holographic projection technology belongs to one of 3D technologies, and refers to a technology for recording and reproducing a real three-dimensional image of an object by using an interference principle. Then, with the guidance of science fiction movies and commercial propaganda, the concept of holographic projection is gradually extended to commercial activities such as stage performance, exhibition and exhibition. In the interference process of the holographic technology, the superposition of the wave crest and the wave crest is higher, the superposition of the wave crest and the wave trough can be flattened, so that a series of irregular and light-dark alternate stripes can be generated, and phase information is converted into intensity information to be recorded on a photosensitive material. When the user interacts with the virtual portrait in a living or working scene, the height of the virtual portrait is higher than that of the user, so that the user has a feeling of being high-lying. The height of the body of the virtual portrait is generally 0.5m, the user places the virtual robot 500 on the desktop, the height of the body of the desktop is assumed to be 0.3 m, at this time, the height of the virtual portrait is 0.8m, if the user lies on a sofa, the height is 0.4m, a height difference of 0.4m is formed between the virtual portrait and the user, and the height of the virtual portrait is adjusted through the device 100, so that the height difference can be reduced. Specifically, the device 100 for adjusting the height difference between the virtual portrait and the user comprises a sound detection module 10, a first spatial position calculation module 20, a distance measurement and calculation module 30, a height difference calculation module 40 and a control module 50; detecting the sound emitted by the user through a sound detection module 10, and positioning a first spatial position of the user according to the detected sound information by matching with a first spatial position calculation module 20; when the first spatial position information is obtained, the first height of the user may be calculated according to the first spatial position of the sound source through the distance measurement and calculation module 30, and the distance measurement and calculation module 30 may be a distance measuring instrument; when the height difference calculating module 40 determines that the second height of the virtual portrait is higher than the first height of the user, the virtual portrait needs to be controlled to execute corresponding operations, for example, bending over, squatting, lowering head, and the like, so as to reduce the height difference, and the control module 50 controls the virtual portrait to execute the corresponding operations according to the height difference. Therefore, by adopting the device 100, the height of the virtual portrait can be reduced in cooperation with the user, so that the intimacy between the virtual portrait and the user is increased, and the user experience is improved.

Referring to fig. 2, in one embodiment of the present invention, the apparatus 100 further comprises:

the camera module 60 is configured to scan an external image, obtain information of the image, and position a second spatial position of the user according to the information of the image.

In this embodiment, when the user does not make a sound and needs to detect the position of the user, the position of the user may be captured by setting the camera module 60; the camera module 60 is a camera including a camera head; the camera module 60 and the sound detection module 10 are in a complementary relationship to each other, and are used for locating the spatial position of the user. In different scenes, the camera module 60 and the sound detection module 10 may be different from each other. If the image acquisition of the camera module 60 is limited in the night scene, the sound source direction of the sound detection module 10 is taken as the leading factor, and the sound detection module 10 detects the spatial position of the user who makes a sound, and determines the positional relationship of the user who makes a sound in a specific space. When a sound source is detected, the camera of the camera module 60 rotates to the sound source position, and at the same time, the user's movement in the sound source direction is detected, and the user's eyes or speaking height is detected. And when the camera module 60 captures the second spatial position of the user, the virtual portrait is turned to the user, so that the interactive experience between the user and the virtual portrait is increased.

In an embodiment of the present invention, the sound detection module 10 includes a microphone array formed by a plurality of microphones, and detects the sound emitted by the user through the microphone array formed by the plurality of microphones to obtain the sound information of the sound.

In this embodiment, a plurality of microphones are distributed at different positions in space according to a predetermined sequence to detect the sound (sound source) emitted by the user, and the first spatial position calculation module 20 performs signal processing on the sound output by each microphone in the microphone array, so as to form spatial directivity. Determining a positional relationship with the user. By this method, it is possible to suppress sound interference other than the target sound, and suppress not only noise but also human voice in other directions.

Referring to fig. 2, in one embodiment of the present invention, the first spatial position calculation module 20 includes:

a semantic judgment sub-module 21, configured to match the sound information with a sentence library, and judge whether the sound information has a semantic meaning;

and the spatial position calculating submodule 22 is used for calculating a first spatial position of the sound source according to the sound information when the sound information has semantic meaning.

In this embodiment, if the semantic determination sub-module 21 determines that the sound detected by the sound detection module 10 has a semantic meaning, the first spatial position calculation module 20 calculates the first spatial position of the sound source from the sound information. The semantic sound is a sound indicating that the user interacts with the virtual portrait or a sound indicating that the user is moving, such as a slipper sound. And the virtual portrait can be subjected to height difference adjustment operation in the process of interacting with the user by judging whether the sound information has semantics.

Referring to fig. 2, in one embodiment of the present invention, the control module 50 further comprises:

a second control sub-module 54, configured to control the virtual portrait to perform a squatting posture if the height difference is smaller than the first threshold and larger than a second threshold; and if the height difference is smaller than the second threshold value, controlling the virtual portrait to execute a head-lowering gesture.

Specifically, the first threshold value is 0.7 m;

the second threshold is 0.2 meters.

In the embodiment, the height of the body of the general virtual portrait is 0.5m, and the height of the body of the person is 1.5-1.8 m; therefore, when the height difference between the virtual portrait and the sound source of the user speaking is detected to be less than 0.2m, the virtual portrait compensates the visual experience difference caused by the height difference through operations of adjusting the head, such as head lowering, head raising and the like. When the height difference between the virtual portrait and the speaking sound source of the user is detected to be larger than 0.2m and smaller than 0.7m, the virtual portrait adopts a natural posture of squatting and the like to reduce the height difference to prioritize the visual difference, and the difference part is filled up by operations of raising head, lowering head and the like. If the height of the sound source of the user is 0.4m (assuming that the user lies on a sofa), and the height of the virtual portrait is 0.8m (the height of the body of the virtual portrait is 0.5, and the height of the body of the table top is 0.3 m), the height of the virtual portrait after squatting is 0.5m, and the height difference of 0.1m is compensated by head-lowering operation. When detecting that the height difference between the virtual portrait and the speaking sound source of the user is larger than 0.7m, the virtual portrait can make up the visual difference by using postures of lying, lying on the stomach and the like, so that the interaction between the user and the virtual portrait is more natural and flexible.

In particular, said third threshold value is 0.7 m;

the angle ranges from 50 degrees to 65 degrees.

In this embodiment, when the height difference between the virtual portrait and the sound source of the user is detected to be greater than 0.7m, the virtual portrait is deflected as a whole, and if the virtual portrait is detected to stand vertically on the ground, when the height difference between the virtual portrait and the sound source is detected to be greater than 0.7m, the angle of the virtual portrait as a whole is deflected by 30 °, that is, the angle with the ground is 60 °.

Referring to fig. 3, in an embodiment of the present invention, there is further provided a method for adjusting a height difference between a virtual portrait and a user, including:

In this embodiment, the height difference between the user and the virtual portrait is reduced by adjusting the height of the virtual portrait, so that the user interacts with the virtual portrait more naturally. Specifically, the sound detection module 10 detects the sound emitted by the user, and cooperates with the first spatial position calculation module 20 to locate the first spatial position of the user according to the detected sound information; when the first spatial position information is obtained, the first height of the user may be calculated according to the first spatial position of the sound source through the distance measurement and calculation module 30, and the distance measurement and calculation module 30 may be a distance measuring instrument; when the height difference calculating module 40 determines that the second height of the virtual portrait is higher than the first height of the user, the virtual portrait needs to be controlled to execute corresponding operations, for example, bending over, squatting, lowering head, and the like, so as to reduce the height difference, and the control module 50 controls the virtual portrait to execute the corresponding operations according to the height difference. Therefore, the height of the virtual portrait matched with the user can be reduced by adopting the method, so that the intimacy between the virtual portrait and the user is increased, and the user experience is improved.

In one embodiment of the invention, the method further comprises: scanning an external image, acquiring information of the image, and positioning a second spatial position of the user according to the information of the image; by means of a camera module 60.

In different scenes, the camera module 60 and the sound detection module 10 may be different from each other. If the image acquisition of the camera module 60 is limited in the night scene, the sound source direction of the sound detection module 10 is taken as the leading factor, and the sound detection module 10 detects the spatial position of the user who makes a sound, and determines the positional relationship of the user who makes a sound in a specific space. When a sound source is detected, the camera of the camera module 60 rotates to the sound source position, and at the same time, the user's movement in the sound source direction is detected, and the user's eyes or speaking height is detected. And when the camera module 60 captures the second spatial position of the user, the virtual portrait is turned to the user, so that the interactive experience between the user and the virtual portrait is increased.
