The invention discloses a three-dimensional spectrogram generation method and device, a terminal and a computer readable storage medium. The three-dimensional spectrogram generation method comprises the steps: acquiring a time parameter, a frequency parameter and an energy parameter of an original spectrogram when a three-dimensional spectrogram generation request is received; generating a first image based on the time parameter and the energy parameter, and generating a second image based on the frequency parameter and the energy parameter; judging whether the first image and the second image meet a preset rule; and if the first image and the second image accord with the preset rule, performing 3D synthesis on the first image and the second image to generate a three-dimensional spectrogram. Therefore, a user can visually, accurately and quickly read related information from the three-dimensional spectrogram, and the spectrogram information reading efficiency and accuracy of the userare improved.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular to a method, device, terminal and computer-readable storage medium for generating a three-dimensional spectrogram. Background technique [0002] A spectrogram is a graph of speech data that uses a two-dimensional plane to express three-dimensional information. The abscissa of the spectrogram is time, the ordinate is frequency, and the coordinate points are the energy of the voice data. Since a two-dimensional plane is used to express three-dimensional information, the size of the energy value is represented by different colors, that is, the color of the coordinate point represents the speech energy value of the speech point, and the darker the color, the greater the speech energy of the coordinate point . At present, when it is necessary to read the energy information of a speech point from the spectrogram, it is necessary to query the color of the speech po...
