As shown in Figures 1 and 2, the imaging display device includes a processor (not shown), an audio receiving device (not shown), a screen (not shown), an imaging body, and a housing. A light-transmitting hole is provided on a designated surface of the housing. The processor and the screen are disposed within the housing, and the audio receiving device is embedded in the housing. The imaging body is disposed on the designated surface. The imaging body includes a beam-splitting film and two identical first and second light-transmitting triangular prisms.

After acquiring the audio information, corresponding imaging information is generated based on the audio information, and then the imaging information is... The system controls the screen to display an image. After the screen displays the image, the light passes through a light-transmitting hole on a designated surface of the housing and is refracted by a beam-splitting film to form an image that can be observed by the user. It should be noted that the image displayed on the screen controlled by this imaging information can be a 3D image, specifically a holographic 3D image.

[0087] Figure 5 is a schematic flowchart of an imaging display method provided in an embodiment of this disclosure. The imaging display method runs in the processor of the imaging display device described above. As shown in Figure 5, the imaging display method is implemented through the following steps:

[0088] Step 501: After acquiring the voice signal through the audio receiving device, the voice signal is processed into frames to obtain multiple voice segments.

[0089] Step 502: For each of the aforementioned speech segments, process the speech segment using the following formula to obtain the speech to be processed:

[0090] Sω(n) = s(n) × ω(n); (Formula 1)

[0091] Where s(n) is the speech segment and ω(n) is the window function.

[0092] Step 503: For each speech segment, determine the frequency domain signal of the speech to be processed using the following formula:

[0093] (Formula 2)

[0094] in, This is the time-domain signal corresponding to the speech currently being processed. The number of sampling points of the speech currently being processed is denoted as n, the sampling sequence number of the time-domain signal is denoted as k, the sampling sequence number of the speech currently being processed in the frequency domain is denoted as j, an imaginary number satisfying j²=-1, e is the base of the natural logarithm, and π is an irrational number.

[0095] Step 504: After obtaining the frequency domain signal corresponding to each speech to be processed, for each frequency domain signal, use the following formula three to obtain the spectral amplitude corresponding to each speech to be processed:

[0096] (Formula 3)

[0097] in, Indicates modulo, is the real part of the frequency domain signal, and Im is the imaginary part of the frequency domain signal.

[0098] Step 505: Based on the time position and frequency component number of the speech to be processed corresponding to each spectral amplitude in the speech signal, map each spectral amplitude to a two-dimensional space with time as the horizontal axis and frequency component number as the vertical axis to obtain a two-dimensional image.

[0099] Step 506: Normalize each spectrum amplitude integer to 0-255 to obtain the normalized value corresponding to each spectrum amplitude.

[0100] Step 507: Determine the hue value of each normalized value according to the following formula four:

[0101] T = (A / 255) * 360; (Formula 4)

[0102] Where A is the normalized value.

[0103] Step 508: Determine the RGB value corresponding to each hue value based on the mapping relationship between hue value and RGB value.

[0104] Step 509: Assign color to the corresponding position in the two-dimensional image according to the obtained RGB values, and control the screen to generate a color image according to the two-dimensional image after color assignment, so that the color image is refracted by the beam splitter after passing through the light-transmitting hole and then imaged on the regular hexahedron.

[0105] Specifically, speech signals are nonlinear, non-stationary, and time-varying random signals, but they can be considered stationary and invariant in the short term. Therefore, after obtaining the speech signal, it is divided into frames according to a preset duration to obtain multiple speech segments. This makes the characteristics of the signal within each frame relatively stable. After framing, there will be discontinuities at the beginning and end of each speech segment. Therefore, the more speech segments there are, the greater the error compared to the original speech signal. To solve this problem and make the framed speech segments continuous, and each speech segment will exhibit the characteristics of a periodic function, a window function needs to be applied to each speech segment. For example, a rectangular window, a Hamming window, a Hanning window, etc. The window function is a sequence of finite length, the same as the length of the speech segment.

[0106] Since frequency domain amplitude can reflect various speech characteristics of users, including energy distribution, formant characteristics, pitch and tone quality, speech emotion and state, etc., these characteristics are of great significance for applications in speech processing, speech recognition, speech analysis and other fields. Therefore, in order to better analyze each speech segment, the frequency domain signal corresponding to each speech segment is obtained by formula two, and then the corresponding spectral amplitude is obtained by formula three. In the above, the value of e is approximately 2.71828, and the value of π is approximately 3.14159.

[0107] Since each speech segment corresponds to a different time period, and different speech segments have different frequency component numbers, and since the frequency component number can characterize various features such as the complexity and clarity of a speech segment, in order to construct an image that matches the current user's speech signal, a two-dimensional coordinate system can be constructed with time as the horizontal axis and frequency component number as the vertical axis. Then, based on the time corresponding to each speech segment and the frequency component number of the corresponding spectral amplitude, each speech segment can be projected onto this two-dimensional coordinate system, thereby obtaining a two-dimensional image composed of multiple points.

[0108] To obtain a colored image, the integer amplitudes of each spectrum can be normalized to 0-255. For example, values ​​greater than 255 are normalized to 255. If the value is not an integer, it is rounded to obtain the corresponding integer, i.e., the normalized value. Then, the normalized value is mapped to the hue value using Formula 4. Based on the preset mapping relationship between hue value and RGB value, the corresponding RGB value for each hue value is determined. The obtained RGB value is then assigned to the corresponding position. In this way, each point on the two-dimensional image obtained above has color, thus obtaining a color image. To prevent the color between adjacent positions in the color image from abruptly changing, continuous and smooth colors can be used to transition between adjacent positions. A color image can be obtained through the above method. Then, the screen is controlled to form an image, which is refracted through the light-transmitting hole and then imaged on a regular hexahedron.

[0109] In one feasible implementation, after the speech signal is framed, the length of each speech segment is 20 to 30 milliseconds.

[0110] In one feasible implementation, the window function is a Hamming window.
