[0046] When doctors diagnose patients with facial paralysis, they need to obtain the facial nerve movement data of the patients for diagnosis in order to conduct subsequent diagnosis. Obviously, the accuracy of the facial nerve movement data used for diagnosis is very important.

[0047] At present, doctors mainly use manual visual methods or CTA and MRI ray scanning methods to capture the movement of facial nerves in patients with facial paralysis. However, due to the limitation of human vision, it is impossible to see high-speed movements such as blinking, so it is difficult for manual visual methods to capture the high-definition details of facial nerve movement in patients with facial paralysis that cannot be seen by the human eye. In addition, since the head position of patients with facial paralysis is not stable, the situation of capturing the movement of facial nerves in patients with facial paralysis is also not stable, and it is heavily dependent on the subjective experience and ability of doctors, so the accuracy of doctors' diagnosis of facial paralysis based on the captured situation is generally average. However, ray scanning methods such as CTA and MRI are harmful to the human body and are suitable for static analysis. When analyzing the dynamic scene of facial nerve movement, the accuracy of diagnosis is also generally average.

[0067] Figure 2 is a flow chart of a method for capturing facial nerve motion data according to one embodiment of the present application. Figure 2 As shown, the facial nerve motion data capturing method of the embodiment of the present application is applied to a facial nerve motion data capturing system 100, and the facial nerve motion data capturing system 100 includes: a head stabilizing device 1, a focusing and lighting device 2, a designated camera 3 and a seat 4; the facial nerve motion data capturing method of the embodiment of the present application may specifically include:

[0068] S201, when the facial paralysis patient sits on the seat, calibrate the head position of the facial paralysis patient based on the head stabilization device.

[0069] In the embodiment of the present application, the facial paralysis patient is the facial paralysis patient to be diagnosed, and the head position is the position of the facial paralysis patient's head. When the facial paralysis patient sits on the seat 4 in the facial nerve motion data capture system, the head position of the facial paralysis patient is calibrated based on the head stabilization device 1 so that the head position of the facial paralysis patient meets the corresponding requirements.

[0070] S202, using a focus and lighting device and a designated camera to adjust the shooting environment for the facial paralysis patient to a shooting environment that meets the target shooting requirements.

[0071] In the embodiment of the present application, the shooting environment refers to the external environment when shooting the facial paralysis patient, for example, the light intensity. The target shooting requirement is the pre-set requirement for shooting. For example, the target shooting requirement for light intensity is 5000Lux. When the light intensity reaches 5000Lux, it means that the target shooting requirement is met. The focusing and lighting device 2 and the designated camera 3 are used to adjust the shooting environment for the facial paralysis patient to a shooting environment that meets the target shooting requirement for subsequent processing.

[0072] S203, in response to the head position of the facial paralysis patient and the shooting environment being calibrated, using a designated camera to record a facial nerve movement image of the facial paralysis patient.

[0073] In the embodiment of the present application, after the head position and shooting environment of the facial paralysis patient are calibrated according to step S201 and step S202, it is determined that shooting can be performed at this time, and the designated camera 3 is used to record the facial nerve movement image of the facial paralysis patient.

[0074] It should also be noted that the designated camera 3 for recording facial nerve movement images in this application is a camera whose shooting speed, shooting resolution and noise meet the corresponding parameter standards. In short, it is a high-definition, high-speed, low-noise camera. With this high-definition, high-speed, low-noise camera, facial details of facial paralysis patients that cannot be captured by the human eye can be captured.

[0075] Optionally, the facial nerve motion image is judged according to a preset qualified video standard to screen out unqualified facial nerve motion images, and the facial nerve movement corresponding to the unqualified facial nerve motion image is re-recorded. Among them, for qualified video standards, for example, the face of the facial paralysis patient fills no less than 50% of the recorded screen, the facial illumination of the facial paralysis patient is not less than 10,000 Lux, there is no shadow on the face of the facial paralysis patient, the full face of the facial paralysis patient is exposed, and there is space between the top and bottom of the recording screen between the top of the head and the bottom of the mandible of the facial paralysis patient, etc. When the facial nerve motion data does not meet these qualified video standards, it is determined to be unqualified facial nerve data, and the facial nerve movement corresponding to the unqualified facial nerve motion image is re-recorded, that is, the facial nerve motion image of the facial paralysis patient performing the facial nerve movement is re-recorded.

[0076] The facial nerve motion data capture method provided in the embodiment of the present application is as follows: when a facial paralysis patient sits on a chair, the head position of the facial paralysis patient is calibrated based on a head stabilization device; the shooting environment for the facial paralysis patient is adjusted to a shooting environment that meets the target shooting requirements using a focusing and lighting device and a designated camera; in response to the calibration of the head position and shooting environment of the facial paralysis patient, the facial nerve motion image of the facial paralysis patient is recorded using a designated camera. The facial nerve motion data capture system of the present application calibrates the head position of the facial paralysis patient and adjusts the shooting environment to meet the target shooting requirements through the facial nerve motion data capture system, and records the facial nerve motion image of the facial paralysis patient according to the designated camera and the focusing and lighting device, so as to capture the facial nerve motion details of the facial paralysis patient that cannot be recognized by the human eye, obtain stable facial nerve motion image data under a stable spatial position and a stable head position, reduce the reliance on the doctor's subjective experience and ability, improve the accuracy of facial paralysis diagnosis, and avoid radiation damage to the human body, reduce the diagnosis cost, and reduce the diagnosis time.

[0077] Further, such as Figure 3 As shown, before calibrating the head position of the facial paralysis patient based on the head stabilizing device 1, the facial nerve motion data capturing method of the embodiment of the present application may further include the following steps:

[0078] S301, for a designated camera and a seat, determining a photographic horizontal line of a camera frame in the designated camera and a backboard horizontal line of the seat.

[0079] In the embodiment of the present application, for the designated camera 3, the photographic horizontal line of the camera frame in the designated camera 3 is determined, and for the seat 4, the backboard horizontal line of the seat 4 is determined for subsequent processing.

[0080] S302, aligning and calibrating the photographic horizontal line and the backboard horizontal line.

[0081] In the embodiment of the present application, the photographic horizontal line of the camera frame in the designated camera 3 determined in step S301 and the horizontal line of the back panel of the seat 4 are aligned and calibrated.

[0082] Thus, a calibration is performed by specifying the photographic horizon of the camera frame in the camera 3 and the backboard horizon of the seat 4 to ensure a stable spatial position.

[0083] Furthermore, the head stabilizing device 1 includes a top pressure plate, such as Figure 4 As shown, the “calibrating the head position of the facial paralysis patient based on the head stabilization device” in step S201 in the above embodiment may specifically include the following steps:

[0084] S401, fixing the head position of the facial paralysis patient based on the top of the head pressure plate, and providing feedback to the head of the facial paralysis patient by generating force sense and / or pressure sense, so that the facial paralysis patient can understand the changes in his / her head position.

[0085] In an embodiment of the present application, the head position of the facial paralysis patient is fixed by the top pressure plate in the head stabilization device 1, and the top pressure plate provides feedback to the head of the facial paralysis patient by generating a sense of force and / or pressure. The facial paralysis patient can understand the changes in his or her head position based on the feedback from the top pressure plate, for example, whether his or her head has moved.

[0086] S402, for the facial paralysis patient, determine the facial pupil line of the facial paralysis patient, and align and calibrate the facial pupil line of the facial paralysis patient with the horizontal line of the backboard.

[0087] In an embodiment of the present application, the facial pupil line is the line between the two pupils on the face of a patient with facial paralysis. The facial pupil line of the patient with facial paralysis is determined, and the facial pupil line of the patient with facial paralysis is aligned and calibrated with the backboard horizontal line in the above embodiment.

[0088] Thus, a calibration is performed through the facial pupil line of the facial paralysis patient and the horizontal line of the back panel of the seat 4 to ensure a stable head position.

[0089] Further, such as Figure 5 As shown, the “calibrating the head position of the facial paralysis patient based on the head stabilization device” in step S203 in the above embodiment may specifically include the following steps:

[0090] S501, for a patient with facial paralysis, determining a plurality of preset groups of facial nerve movements for the patient with facial paralysis.

[0091] In an embodiment of the present application, facial nerve actions are pre-set facial nerve actions for judging patients with facial paralysis. The multiple groups of facial nerve actions include multiple eye actions and multiple facial actions, among which eye actions include closing eyes, and facial actions include raising eyebrows, pouting lips, etc. For the patient with facial paralysis to be diagnosed, the multiple groups of facial nerve actions of the patient are determined for subsequent processing.

[0092] S502, generating corresponding action instructions based on multiple groups of facial nerve movements, so that the facial paralysis patient performs the designated facial nerve movement corresponding to the action instruction according to the action instruction, and records the facial nerve movement image corresponding to the facial nerve movement according to the designated camera.

[0093] In an embodiment of the present application, the action indication is the indication corresponding to each facial nerve action, for example, a voice indication, etc. For example, when the facial nerve action is blinking, the corresponding action indication may be "please blink". The designated facial nerve action is the facial nerve action corresponding to the action indication. For example, when the action indication is "please blink", the corresponding designated facial nerve action is blinking. After hearing the action indication, the facial paralysis patient will perform a blinking action to complete all facial nerve actions. The facial nerve motion image is the image corresponding to the facial nerve action recorded by the facial paralysis patient after the facial nerve action is performed. The corresponding action indication is generated for each facial nerve action in the multiple groups of facial nerve actions determined based on step S501, so that the facial paralysis patient makes the designated facial nerve action corresponding to the action indication according to the action indication, and the facial nerve motion image of each facial nerve action in the multiple groups of facial nerve actions is recorded according to the designated camera 3.

[0094] It should be noted that the action indication can not only indicate the corresponding facial nerve action, but also include frequency, time and other contents, for example, "please blink 10 times, each time with an interval of 2 seconds", and this application does not make too many restrictions on this. Furthermore, in the process of recording the facial nerve movement image of a patient with facial paralysis; when the head position of the patient with facial paralysis moves, the displacement angle of the head position of the patient with facial paralysis is determined; in response to the displacement angle not exceeding the preset target displacement angle, the patient with facial paralysis is reminded to adjust his head position; in response to the displacement angle exceeding the preset target displacement angle, in response to the displacement angle not exceeding the preset target displacement angle, the facial nerve action corresponding to the recording process is re-recorded. Among them, the target displacement angle is the sensitive angle at which the human eye can perceive head movement; the displacement angle is the displacement angle of the head position of the patient with facial paralysis in the target axis (for example, the XYZ axis). For example, the human eye can perceive a sensitive angle of head movement of 5°, so the target displacement angle is 5°. When the displacement angle of the head of a patient with facial paralysis exceeds 5°, it means that the head movement of the patient with facial paralysis is large. At this time, the facial nerve motion image of the corresponding facial nerve movement during the recording process is re-recorded. If the head displacement angle of the patient with facial paralysis does not exceed 5°, a corresponding action instruction can be generated to enable the patient with facial paralysis to adjust his or her head position according to the action instruction. For example, when the head displacement angle of the patient with facial paralysis does not exceed 5°, the corresponding action instruction is generated as "slightly tilt to the right" to guide the patient with facial paralysis to adjust his or her head position.

[0095] Furthermore, before using the designated camera 3 to record the facial nerve movement image of the facial paralysis patient, the target photography mode of the designated camera 3 is determined according to the facial nerve movement; and the photography mode of the designated camera 3 is adjusted to the target photography mode. Among them, the target photography mode includes high-speed photography and low-speed photography. For example, when the facial nerve movement is an eye movement, such as closing the eyes, in order to obtain the details of the eyes of the facial paralysis patient that cannot be seen by the human eye, a high-speed mode is required, that is, the designated camera 3 is switched to a high-speed photography mode, and when the facial nerve movement is a facial movement, such as pouting, the eye movement does not require such a high shooting speed, and at this time, the designated camera 3 only needs to be switched to a low-speed photography mode.

[0096] Furthermore, the shooting environment includes at least shooting parameters and illumination parameters; the illumination parameters include at least light intensity; and the shooting parameters include at least depth of field and pixel density.

[0097] Acquire shooting experiment data combined with a preset shooting algorithm; acquire target shooting parameters of the designated camera 3 and target illumination parameters of the focus and illumination device 2 based on the preset shooting experiment data; adjust the shooting parameters of the designated camera 3 based on the target shooting parameters, and adjust the illumination parameters of the focus and illumination device 2 based on the target illumination parameters. The shooting algorithm is a preset shooting algorithm, the target shooting parameters at least include shooting rate, aperture value, focal length value; the target illumination parameters at least include light intensity.
