Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The three-dimensional pulse wave display method provided by the application can be applied to the application environment shown in fig. 1. The application environment includes a server 101 and a display terminal 102, and the server 101 communicates with the display terminal 102 via a network. The server 101 generates a pulse wave animation file according to the spatial distribution information of the pulse condition and sends the pulse wave animation file to the display terminal 102; the display terminal 102 displays the corresponding three-dimensional pulse wave according to the augmented reality technology. The server 101 may be implemented by an independent server or a server cluster composed of a plurality of servers; of course, the server 101 may be replaced by a terminal having a data processing function, such as a smartphone. The display terminal 101 may be, but is not limited to, various televisions with display screens, personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices (e.g., head-mounted display devices, etc.).

The embodiment of the invention provides a method and a device for displaying three-dimensional pulse waves, computer equipment and a storage medium. The following are detailed below.

In one embodiment, as shown in fig. 2, a method for displaying a three-dimensional pulse wave is provided. Taking the application of the method to the server 101 in fig. 1 as an example for explanation, the method includes the following steps:

s201, acquiring space distribution information of pulse conditions; the spatial distribution information of the pulse condition is determined according to the pulse condition sensing information of the pulse.

The pulse may refer to various types of pulses on a human body, for example: cun pulse, guan pulse, chi pulse (cun pulse, guan pulse and chi pulse together may be referred to as cun guan chi), etc. The pulse condition sensing information may refer to pulse condition information measured by the pulse condition sensing device. Since the pulse is usually a region corresponding to the surface of the human body, the pulse condition sensing device needs to acquire the sensing information of the region. Based on this, the spatial distribution information of the pulse condition, i.e. the information of the pulse condition at a specific spatial position (e.g. the pressure data at a certain position) can be determined according to the pulse condition sensing information of a region.

The pulse condition sensing device can be various sensors, and the sensors can be arranged on the pulse diagnosis instrument. The plurality of sensors are arranged together to form a sensor array, so that pulse condition sensing information can be acquired through the sensor array. The sensor array can be as shown in fig. 3, and a plurality of sensors are arranged in a criss-cross manner to form the sensor array, so that the sensor array can acquire pulse condition information of each position in the area where the pulse is located. The sensor may be a pressure sensor or the like. Specifically, the pulse condition sensing device may be a capacitive pressure sensor (the corresponding pulse condition sensing information is pressure value information). While the sensor array may have some flexibility.

Further, the step of obtaining the spatial distribution information of the pulse condition comprises: receiving pulse condition sensing information of an area where a pulse is sent by a sensor array; acquiring the arrangement relation of the sensor array; integrating the pulse condition sensing information according to the arrangement relationship to obtain the spatial distribution information of the pulse condition. The area where the pulse is located refers to a small area on the skin surface where the pulse can be sensed (the boundary of the area can be determined according to whether the sensor can sense the pulse condition information).

S202, obtaining a three-dimensional pulse wave according to the space curved surface information in the set format; the spatial surface information is generated from the spatial distribution information.

Since the spatial distribution information is the pulse condition information in a certain space, the process of pulse up-and-down beating can form a curved surface in a small range, as shown in fig. 4. The obtained spatial distribution information is integrated to a certain extent, so that corresponding spatial curved surface information can be obtained; this integration process may be a certain operation or format conversion of the spatial distribution information. In addition, the set format may be FBX, DAE, STL, OBJ, or the like, and the specific format selected may be determined as the case may be.

Furthermore, the spatial curved surface information at a certain moment may correspond to a curved surface, and the spatial curved surface information at multiple moments may correspond to a continuously-jumping curved surface. The information corresponding to the continuously pulsating surface is a three-dimensional pulse wave (in some embodiments, the three-dimensional pulse wave may also be referred to as a pulse condition model).

S203, obtaining a pulse wave animation file corresponding to the three-dimensional pulse wave, and sending the pulse wave animation file to a display terminal; the pulse wave animation file is used for triggering the display terminal to display the three-dimensional pulse wave according to the augmented reality technology.

The pulse wave animation file refers to an animation file representing information such as the shape, size, amplitude, playing rate and the like of the three-dimensional pulse wave, wherein the pulse wave animation refers to animation corresponding to the three-dimensional pulse wave.

Augmented Reality (AR) is a new technology for integrating real world information and virtual world information in a superimposed manner. By means of the electronic information science technology and corresponding equipment, the AR technology simulates and superposes objective information (such as visual information, touch sense or other information and the like) which is limited by a time space range and is difficult to experience in the original real world, and then applies the objective information to the real world, so that human sense can generate the illusion that the object information exists in the real world, and the beyond-reality sense experience can be achieved.

The display terminal refers to a terminal for displaying three-dimensional pulse waves, and may refer to a simple display screen, or a terminal with a display screen, for example: televisions, personal computers, notebook computers, smart phones, tablet computers, head-mounted display devices, and the like. When the display terminal is a smart phone, the system of the smart phone can be Android, IOS, Windows and the like, and tools such as ARKit, ARCore and the like can be configured on the smart phone. When the display terminal is a head-mounted display device, the display terminal may be a device such as a Hololens device, a Magic Leap lightnear device, or the like. Specifically, for example, in the case of a head-mounted display device, after receiving a pulse wave animation file sent by the server 101, the Hololens displays a three-dimensional pulse wave on a display screen by outputting the pulse wave animation file.

Can be provided with the camera on the demonstration terminal, this camera can be the camera that has the degree of depth sensing function, and this kind of camera that has the degree of depth sensing function can carry out snatching of three-dimensional characteristic point to human parts such as wrist, and then directly acquire the spatial position of pulse. If the display terminal is not provided with a camera with a depth sensing function but a plane camera, a sticker can be pasted on the radial artery and other positions, and the space position of the pulse is determined through the recognition of the sticker.

Taking a smart phone as an example, a three-dimensional pulse wave displayed on the smart phone by the augmented reality technology can be shown as fig. 5/6/7. The graph 5/6/7 shows the corresponding three-dimensional pulse wave near the cun-guan position of the wrist (the three-dimensional pulse wave in the graph represents the raised skin surface during pulse beating), and the displayed three-dimensional pulse wave is very intuitive. In addition, because the displayed three-dimensional pulse wave is a pulse condition curved surface which changes in real time, the difference of different pulse conditions in form can be well embodied in the displayed three-dimensional pulse wave, such as: the three-dimensional pulse wave of the flat pulse is similar to a cone-shaped curved surface, while the string pulse is obviously elongated in the blood flow direction and is in a 'string' shape, and the three-dimensional pulse waves of the two pulse conditions are obviously distinguished and clear at a glance.

Meanwhile, the display terminal can display the three-dimensional pulse wave in an interactive mode with the user, for example, when the camera of the display terminal identifies the wrist of the human body, the three-dimensional pulse wave is displayed near the wrist of the human body. The playing speed, the playing angle and the like of the displayed three-dimensional pulse wave can be controlled, and the interactivity of the three-dimensional pulse wave display is effectively improved.

Before the three-dimensional pulse wave is displayed through the display terminal, the pulse wave animation file can be processed through a specific tool (such as Unity 3D) so that the pulse wave animation file can be better displayed on the display terminal in an AR manner.

The display method of the three-dimensional pulse wave can convert abstract pulse condition information into a pulse wave animation file, and display the three-dimensional pulse wave through an augmented reality technology, wherein the displayed three-dimensional pulse wave is very visual; and according to the characteristics of the augmented reality technology, a user can display the three-dimensional pulse wave as required, and meanwhile, the interaction with the three-dimensional pulse wave display can be realized, so that intelligent human-computer interaction is realized.

In one embodiment, before the step of obtaining the three-dimensional pulse wave according to the spatial curved surface information with the set format, the method further includes: and generating the spatial curved surface information in the STL format according to the spatial distribution information. Further, determining the spatial distribution information and performing format conversion on the spatial distribution information may be implemented by a matlab tool. The embodiment determines the spatial curved surface information in the STL format, and the STL format can be well used in tools such as matlab and the like, so that the efficiency of displaying the three-dimensional pulse wave is improved.

Of course, the process of determining the spatial distribution information and performing format conversion on the spatial distribution information may be implemented by software such as Rhinoceros, solidworks, maya, and the like. At this time, spatial surface information in other formats may be generated.

In one embodiment, the step of obtaining a pulse wave animation file corresponding to a three-dimensional pulse wave includes: and arranging the three-dimensional pulse waves according to a time sequence, and obtaining a pulse wave animation file according to the arranged three-dimensional pulse waves.

Wherein, the step of arranging the three-dimensional pulse wave according to the time sequence comprises: performing color rendering on the three-dimensional pulse wave according to the height of the three-dimensional pulse wave; and arranging the rendered three-dimensional pulse waves according to a time sequence. Further, color rendering of the three-dimensional pulse wave can be realized through a certain algorithm; it can also be implemented by specific tools, such as: matlab, maya, etc. The process of color rendering through maya may be: performing color rendering on the three-dimensional pulse wave frame by frame (for example, the color is red when the amplitude of the waveform is higher, and the color is blue when the amplitude is lower, namely, the colors of the waveform from high to low are in transition in the order of red, orange, yellow, green and blue); color rendering can also be achieved by combining matlab and maya: generating space curved surface information of the three-dimensional pulse wave by utilizing the matlab; the colormap corresponding to each frame of the space surface information is added with the corresponding pulse wave animation information block (a plurality of pulse wave animation information blocks form a pulse wave animation file) in maya.

Further, maya arranges the rendered three-dimensional pulses according to a time sequence, so as to obtain a pulse animation file, and at this time, the pulse animation file in fbx format can be played everywhere (the pulse animation file in fbx format can be conveniently played on a tool such as a mobile phone, and of course, can be in other formats).

The step of obtaining the pulse wave animation file according to the arranged three-dimensional pulse wave comprises the following steps: adjusting the set parameters of the arranged three-dimensional pulse waves to obtain a pulse wave animation file; the setting parameters include a display size and a play rate. The display size determines the proportional relation between the three-dimensional pulse wave and the anchor point during AR playing, so a reasonable initial value needs to be set; the initial value of the playing speed is the real playing speed of the three-dimensional pulse wave.

According to the three-dimensional pulse wave display method provided by the embodiment, before the pulse wave animation file is generated, the color rendering, the time arrangement, the parameter adjustment and other processing are performed on the space curved surface information, so that the displayed three-dimensional pulse wave can be more visual, and the intelligence of the interactive display of the three-dimensional pulse wave is improved.

In one embodiment, the step of sending the pulse wave animation file to the display terminal includes: sending the pulse wave animation file to an ftp server; sending file in-place information to a display terminal; the file in-place information is used for triggering the display terminal to download the pulse wave animation file from the ftp server, and the pulse wave animation file is output according to the augmented reality technology. The file in-place information is used for indicating whether the pulse wave animation file is sent to the ftp server or not.

The ftp server is used for storing the pulse wave animation file and providing network support for display of the display terminal. After downloading the pulse wave animation file from the ftp server, the display terminal can store the pulse wave animation file in the memory, and then read the pulse wave animation file in the memory when the three-dimensional pulse wave display is needed. Of course, the server 101 may directly transmit the pulse wave motion picture file to the display terminal without relaying through the ftp server. The server 101 may transmit the pulse wave animation file to the ftp server in real time to display the three-dimensional pulse wave in real time.

According to the three-dimensional pulse wave display method provided by the embodiment, the display terminal acquires the pulse wave animation file and displays the corresponding three-dimensional pulse wave according to the augmented reality technology, so that the display terminal can display the three-dimensional pulse wave in real time, and the convenience of displaying the three-dimensional pulse wave is improved.

In some embodiments, the ftp server may be replaced with a web server, an nntp server, an smtp server, and the like. In addition, taking the ftp server as an example, the server 101 may not transmit the pulse wave animation file to the ftp server; instead, upon receiving a file acquisition instruction transmitted from the display terminal, the ftp server accesses the server 101, and the server 101 returns the pulse wave animation file to the ftp server or directly transmits the pulse wave animation file to the display terminal.

In addition, the purpose of the server 101 outputting the file-in-place information is to prompt the user that the pulse wave animation file has been sent to the ftp server. Therefore, the server 101 may transmit the file in-place information to another terminal that the user can touch, instead of transmitting the file in-place information to the display terminal, and when the user acquires the information that the pulse wave animation file has been transmitted to the ftp server, the display operation of the three-dimensional pulse wave may be performed through the display terminal.

In an embodiment, as shown in fig. 8, an embodiment of the present invention provides a method for displaying a three-dimensional pulse wave, which is described by taking the method as an example for being applied to the display terminal 102 in fig. 1, and includes the following steps:

s801, obtaining a pulse animation file corresponding to the three-dimensional pulse; the pulse animation file is obtained according to the space curved surface information of the pulse.

S802, determining the space position of the pulse, and determining the display position on the display area of the display screen according to the space position.

The display area of the display screen may refer to a display frame of the display screen. As shown in fig. 5/6/7, the display position may be a certain position on the display area. Taking the example of displaying the three-dimensional pulse wave on the wrist of the human body as an example, the customs position of the wrist of the human body in the display area can be determined, and a certain position (for example, a certain distance above) near the customs position is determined as the display position.

When the display terminal is provided with the camera with the depth sensing function, the space position of the pulse can be determined directly through the display terminal, and then the display position is determined. When the display terminal is not configured with a camera having a depth sensing function, the spatial position of the pulse can be determined based on the image detection technique of the high-pass Vuforia.

Further, taking the display terminal as a mobile phone as an example, the implementation process of determining the display position may be: the method comprises the steps of shooting an image of a wrist of a human body through a camera on a mobile phone, determining the spatial position of the wrist dimension according to the shot image based on the image detection technology of high-pass Vuforia, and determining the display position of a three-dimensional pulse wave when the three-dimensional pulse wave is displayed on a screen of the mobile phone according to the spatial position.

And S803, outputting the pulse wave animation file on the display position according to the augmented reality technology to display the three-dimensional pulse wave.

In the method for displaying a three-dimensional pulse wave provided in this embodiment, the display terminal determines the display position on the display screen after acquiring the pulse wave animation file, and then displays the corresponding three-dimensional pulse wave according to the augmented reality technology.

In one embodiment, S801 includes: receiving file in-place information; and downloading the pulse wave animation file from the ftp server according to the file in-place information, and outputting the pulse wave animation file according to the augmented reality technology.

In one embodiment, the three-dimensional pulse wave comprises a single pulse period of the three-dimensional pulse wave; wherein a single pulse cycle comprises a plurality of time instants. The plurality of time instants may be determined in dependence on a sampling frequency of the sensor array.

The pulse signal can be regarded as a periodic signal as a whole. Research shows that under the condition of stable measurement conditions, the ratio of nonlinear components in the measured pulse wave signal is not more than 5%, so that on the premise of ensuring the playing effect, in order to save the calculation amount and improve the efficiency of the display terminal, a single pulse period can be intercepted from the pulse wave original signal to carry out animation production, and the periodic pulsation of the three-dimensional pulse wave is realized in a circulating manner. Further, the step of outputting the pulse wave animation file on the display position according to the augmented reality technology comprises: according to the augmented reality technology, a pulse wave animation file is output on a display position for multiple times so as to periodically display a three-dimensional pulse wave of a single pulse period.

Of course, in order to improve the accuracy of the displayed three-dimensional pulse wave, a plurality of cycles of pulse wave animation files may be acquired, or a continuous pulse wave animation file may be acquired and displayed in real time.

In one embodiment, an anchor point may be set on the display terminal according to the display position; the anchor point is used for controlling the relative position of the three-dimensional pulse wave and the display position to be kept unchanged in the display area when the position of the display screen is changed.

The region corresponding to the display position may be set as an anchor region, or a region near or related to the display position may be set as an anchor region. Further, an anchor point area can be determined according to the spatial position of the pulse, and then an anchor point is set, so that the anchor point area keeps a position-invariant state in the display screen, for example: and setting an anchor point in the area where the inch-scale is located.

When the three-dimensional pulse wave is a pulse wave corresponding to a plurality of pulse waves, an anchor point may be set for each pulse wave, so that each pulse wave is maintained at a fixed position in the display environment (virtual environment in which the displayed content is located).

The embodiment can realize the motion tracking of the display terminal, that is, when the position of the display terminal changes, the displayed three-dimensional pulse wave is ensured to be kept unchanged relative to the display position in the screen, that is, the method can be understood as follows: no matter how the display screen rotates, the position of the three-dimensional pulse wave in the display environment is fixed, and the process of screen rotation can be understood as observing the three-dimensional pulse wave from different angles, so that the intelligent interaction of the three-dimensional pulse wave display can be effectively improved.

In one embodiment, a user may log in a preset APP on a display terminal, where the APP is pre-configured with a related implementation program for enhancing the display technology. Based on this, after the user logs in the APP, the AR display of the three-dimensional pulse wave can be performed by acquiring the corresponding pulse wave animation file. In order to facilitate users to observe and learn the AR pulse condition model better, basic operation functions such as rotation, scaling, speed change and the like can be added in the APP; the method comprises the steps that a model transformation function is provided for meeting the requirement that a user views different pulse condition model examples in a current account (the model examples can refer to pulse condition models of different positions or different display modes pre-stored by the user, and of course, an APP (application) can also obtain pulse wave animation files from an ftp (file transfer protocol) server and the like in real time); as shown in fig. 9 (a), the initial login interface of APP is provided, after a correct user name and password are input, if multiple sets of models exist under the user name, the user can jump to the model selection interface shown in fig. 9 (b); in order to meet the requirements of a large amount of data of future users and protect personal privacy, multi-user account switching is supported; finally, considering the factor of operating the APP with one hand, a UI interface is designed (as shown in (c) of fig. 9) that facilitates one-handed operation and can switch between left and right-handed modes, providing a good interactive experience for the user.

These functions are described in detail below, taking as an example a three-dimensional pulse wave that shows the inch-off scale on the wrist:

one, basic operation function

1. And (4) zooming. Zooming, which refers to changing the size of the currently played model, can be accomplished using a Slider in the Unity UGUI component package. The Slider assembly Slider is first initialized and listening is set. When the user carries out interactive operation and the value of the sliding strip is changed, monitoring can be triggered to obtain the current target pulse condition model, and the size of the model is adjusted by using a method provided by transform. As shown in fig. 5, the size of the model can be changed by moving the lateral slide bar (fig. 5 (a) is the original size, (fig. 5 (b) is the reduced size, and fig. 5 (c) is the enlarged size), and as can be seen from fig. 5, the relative position between the pulse wave and the pulse wave remains unchanged after the model size is changed.

2. And (4) rotating. The rotation is to change the angle of the currently played pulse condition model, so that the three pulse condition models rotate around the middle point. In order to enable the user to determine the degree of rotation of the current model more intuitively, a circular slider assembly radialslide which can rotate 360 ° can be used to achieve this function. Components may also be bound to events of the model. Monitoring is set for the angle value of the assembly radialslide, when the angle changes, the current target pulse condition model and the rotation central point thereof are obtained, and a Rotate method is called to enable the models at two positions of 'cun' and 'chi' to Rotate around the model at the 'off' position. Fig. 6 (a) shows the original three-dimensional pulse wave, (b) shows the three-dimensional pulse wave after small angle rotation in fig. 6, and (c) shows the three-dimensional pulse wave after large angle rotation in fig. 6. In addition, clicking the square button in the middle of the circular sliding bar can restore the pulse condition model to the initial state.

3. The playing speed. The function of model playing speed is also realized by a component Slider in UGUI, and the method is similar to that in zooming. When the value of the sliding bar is changed and monitoring is triggered, a pulse animation file identifier bound in a target model in an FBX format is obtained, a speed method is called to modify the playing speed, the vertical sliding bar in the figure 7 can be rotated, the (a) in the figure 7 is the original three-dimensional pulse playing speed, the (b) in the figure 7 is the fastest playing speed, and the (c) in the figure 7 is the slowest playing speed. Meanwhile, a heart rate file corresponding to the model can be read, the actual heart rate speed and the playing speed of the current pulse condition model are obtained through calculation, and the actual heart rate speed and the playing speed are displayed on the upper corner of the screen through Text.

4. And (6) resetting the model. This function can be accomplished through a Button component. First, every time a group of models is selected and drawn at the correct position of the wrist, parameters such as the spatial coordinates, the rotation quaternary vector, the size, the playing speed and the like of the current model are recorded (as shown in fig. 7 (a)), and when a user clicks a button, the button is triggered to click and monitor, and all drawn model parameters are restored to initialization.

The key code for the custom circular slider assembly implementation is as follows. Where angle is the angle of rotation of the slider.

The key code for rate, angle and size adjustment of the target model is as follows, where anim1 is the animation of the pulse condition model binding.

The key code for reading and drawing the pulse condition model file from the local is as follows:

second, model selection

Each user may have multiple different sets of pulse condition models, and when the user logs in, they need to select the pulse condition that they want to watch in the main interface. This functionality is implemented primarily using the DropDown component DropDown provided in the Unity UGUI.

1. And (5) realizing the function of the elastic frame. First is user data acquisition and bullet box initialization. When the user jumps to the main interface from the login interface, the user name and the model number which are transmitted can be obtained through PlayerPrefs, and therefore the pulse condition model array Usermodel corresponding to the current user is obtained. And traversing the model array Usermodel, and adding the name of each model group in the array into one item in the DropDown component, so as to complete the content filling of the option bullet box. The second step is a pop-up click event. Monitoring is set for the popup window, when a click selection event occurs, the content of the currently selected option can be obtained, and here, in order to facilitate automatic correspondence from the option to the model group, a special model file naming rule can be established, and one-to-one mapping of the pulse condition model, the affiliated user, the affiliated group and the position (inch rule) of the model is realized. When one group is selected, the pulse condition models of three different positions of the group can be obtained.

2. And (4) switching models. Before the model switching is realized, the corresponding model is drawn at the wrist image identifier. Because the models to which the users belong are all stored in the FTP background, the model files are downloaded to a certain specific path of the memory of the mobile phone of the users after login is successful, and therefore the files need to be read firstly: by using a LoadFromFile method and combining with memory relative path application. After a user selects a model, the currently displayed pulse condition model is replaced and drawn into the selected pulse condition model, a function named ChooseModel can be realized in a project, the first step is to store the unique identifier of the original model and destroy the original model, the second step is to load the required model file from the local mobile phone and draw and display the model file by using an instantate method, the parameters such as the size and the coordinates of the new model are set, and the last step is to assign the identifier of the original model to the new model and return the new model to an object, so that the switching from the old model to the new model can be realized.

Third, user's habits

The UI interface convenient for one-hand operation is designed, the layout is simple and attractive, the operations of rotation, zooming and the like can be completed by only one finger, and all interaction components are placed in a range which can be easily reached by one hand. Considering the handedness of different users, a Button can be used to complete the left-right switching and interface adaptive functions of the component. In the Start method, an integer counting mark is used to determine whether the left-hand or right-hand interface is currently used (the left-hand interface is shown in fig. 5, and the right-hand interface is shown in fig. 6 and 7), and then the length and width of the current device screen are obtained, and the relative position and proportion of the components are set according to the size. The user can switch the UI interface left and right through a square button at the lower right of the interface. And clicking a setting button at the upper left corner of the screen, and skipping to a setting interface to select a custom layout or log out a user.

The display method of the three-dimensional pulse wave provided by the embodiment is provided with various functions which can be controlled by a user, the three-dimensional pulse wave can be displayed according to the requirements of the user, and very good interactive experience is provided.

In order to better understand the above method, an application example of the three-dimensional pulse wave display method of the present invention is described in detail below, taking the three-dimensional pulse wave display on the wrist of a human body through a mobile phone as an example.

1. And pressure value information of the cun-guan-chi area on the wrist of the human body is obtained through a pressure sensor array on the pulse diagnosis instrument. And the server determines the spatial distribution information of the pulse condition through a matlab tool according to the pressure value information and the arrangement information of the sensor array.

2. And the server determines the space curved surface information at the corresponding moment through a matlab tool and stores the space curved surface information into an STL format one by one.

3. The server arranges the spatial curved surface information in the STL format according to the time sequence through the maya tool to form a 3D animation file, performs operations such as color rendering and parameter adjustment on the animation file, and finally derives a pulse wave animation file in the fbx format.

4. The server performs batch processing on the pulse wave animation files by using Unity, puts the pulse wave animation files into an ftp server together, and sends file in-place information to the mobile phone.

5. After receiving the file in-place information and receiving a pulse animation playing instruction sent by a user through the APP, the mobile phone shoots an image of the wrist of the human body through the camera (at the moment, the wrist of the human body needs to enter the monitoring range of the camera), and the spatial position of the inch on the wrist of the human body is determined through the image; and determining the display position of the three-dimensional pulse wave on the display screen according to the space position.

6. And the mobile phone downloads the corresponding pulse wave animation file from the ftp server, and outputs the pulse wave animation file on the display position according to the augmented reality technology to realize the display of the three-dimensional pulse wave.

The traditional pulse diagnosis instrument product mainly uses a single-point sensor to simulate fingertips for measurement, the obtained data is simple one-dimensional blood pressure time waves, and the inherent deficiency of data dimension causes a large amount of pulse wave details to be lost, so the one-dimensional blood pressure time waves with the information loss are difficult to be translated into pulse conditions. Embodiments of the present invention integrate the sensor array for measurement. The pulse wave obtained by the multi-point sensor is a three-dimensional image and can be directly used for comparing the finger-down feeling when the pulse is manually taken, so that the successful translation of the pulse wave to a three-dimensional data model is realized. The three-dimensional pulse wave image is played back and analyzed through the increasingly popular AR platform of the mobile phone, so that the bouncing three-dimensional pulse wave is directly 'long' on the wrist. The method is convenient for relevant researchers to flexibly switch and observe the visual angle of the three-dimensional pulse wave so as to quickly find each characteristic region of the pulse wave image, and also enables traditional Chinese medicine researchers to freely observe and experience the complete pulse condition and feel the finger feeling on the wrist at any time and any place, thereby converting the state that the traditional pulse diagnosis study can be only realized through language description.

In addition, the three-dimensional pulse wave can be better spread and shared through the mobile phone. The distance between the pulse diagnosis instrument and a user is shortened in an AR vivid mode, and the spread and the popularity of the traditional Chinese medicine pulse condition and the pulse diagnosis are improved. In summary, the three-dimensional pulse wave is projected on a real plane or the original pulse taking point position of the user, so that the characteristics of the three-dimensional pulse wave are more intuitively released, and a method with higher information content and more convenient observation is provided for multi-angle observation, pulse condition analysis, pulse condition recording and finger sense translation.
