Description

A method for four-dimensional waveform fusion display Technical Field

[0001] This invention relates to the field of electronic measuring instruments, and in particular to a waveform fusion display method. Background Technology

[0002] Currently, three-dimensional fusion information display technology exists in electronic measuring instruments such as oscilloscopes, vibration signal acquisition instruments, and spectrum analyzers. For example, digital phosphor oscilloscopes can use the horizontal axis to represent time, the vertical axis to represent voltage value, and waveform brightness to represent probability information, allowing users to intuitively observe the relationship between voltage, time, and probability information in the image. Spectrum analyzers also use waterfall plots, where each horizontal line represents one acquisition, the vertical axis represents time, the horizontal axis represents frequency, and different color temperatures / brightness represent amplitude. Although more and more electronic measuring instruments have the ability to display acquired results as waveform images, the existing display methods such as scatter plots, curves, digital phosphor images, and waterfall plots can only fuse and display information from three dimensions at most, which cannot yet meet users' needs for displaying more dimensions. Summary of the Invention

[0003] In view of this, the present invention provides a four-dimensional waveform fusion display method, which utilizes 3D digital model construction and image generation technology to intuitively display four-dimensional waveform information, overcomes the above-mentioned shortcomings, and improves the amount of information in the image. The specific technical solution is as follows:

[0004] A four-dimensional waveform fusion display method is proposed, which obtains three-dimensional information from a frame image and fuses the three-dimensional information into a frame 2D image. The three-dimensional information is displayed through the X-axis, Y-axis, and brightness or color at each (X, Y) position. The 2D images corresponding to multiple frames are unfolded along the Z-axis according to the order of each generated frame to complete the fusion display of the four-dimensional waveform.

[0005] Furthermore, in the VT fluorescence waveform display of the fluorescence oscilloscope, the X-axis represents the sampling time of each sampling point in a frame of waveform data displayed by the oscilloscope.

[0006] Furthermore, in the VT fluorescence waveform display of the fluorescence oscilloscope, the Y-axis represents the voltage amplitude at each sampling point on the waveform.

[0007] Furthermore, in the VT fluorescence waveform display of a fluorescence oscilloscope, the digital fluorescence brightness of the waveform represents the probability of that sampling point occurring.

[0008] Furthermore, in the VT fluorescence waveform display of the fluorescence oscilloscope, the Z-axis represents the order in which multiple frames of waveform data are generated. Beneficial effects

[0009] 1. This invention combines 3D image generation technology with data acquisition information feature fusion extraction technology to fuse and display the four-dimensional information of the acquired data, which can effectively increase the amount of information in the image;

[0010] 2. By using this invention, users can intuitively observe the changes in long-term waveforms through four-dimensional waveforms;

[0011] 3. Using this method, users can know the possible locations and approximate probability of occasional burrs;

[0012] 4. By using this invention, no additional cost is required; the display function of more information can be realized solely through software, resulting in a low implementation cost. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] A four-dimensional waveform fusion display method is shown in Figure 2. This embodiment can be applied to the four-dimensional waveform information display of the VT fluorescent waveform of an oscilloscope.

[0018] In the VT fluorescence waveform display of a fluorescence oscilloscope, the X-axis represents the sampling time of each sampling point in a frame of waveform data displayed by the oscilloscope, the Y-axis represents the voltage amplitude of each sampling point on the waveform, and the digital fluorescence brightness of the waveform represents the probability of the occurrence of that sampling point. All of these three types of information can be displayed in a frame of image, that is, three-dimensional information is fused and displayed in a frame of 2D image.

[0019] By applying the proposed four-dimensional waveform fusion display method, in this embodiment, the X-axis represents the sampling time of each sampling point in a frame of waveform data displayed by the oscilloscope, the Y-axis represents the voltage amplitude of each sampling point on the waveform, the digital fluorescence brightness of the waveform represents the probability of the sampling point appearing, and the Z-axis represents the order of each generated waveform (the waveform closer to the origin is acquired earlier). A total of four types of information can be displayed in a single frame, that is, four-dimensional information is fused and displayed in a single frame of 3D image.

[0020] The specific steps of the method provided by this invention in the embodiments are as follows:

[0021] S00. The oscilloscope completes the acquisition of the first frame of waveform data, 3D information fusion, and 2D waveform image generation in the original conventional manner.

[0022] S01. Place the first frame waveform image at the origin of the Z-axis;

[0023] S02. The oscilloscope completes the acquisition of the next frame of waveform data, the fusion of three-dimensional information and the generation of 2D waveform image in the original conventional manner;

[0024] S03, Place the waveform image of this frame at the next interval point on the Z-axis origin;

[0025] S04. Repeat S02 to S03. The waveform on the screen will increase as the oscilloscope completes the acquisition time, gradually forming a complete 4D waveform that integrates four-dimensional waveform information.
