Description

A facial nerve motion data capture system and method

[0001] Cross-reference to related applications

[0002] This disclosure claims priority to Chinese Patent Application No. 2024111950355, filed on August 29, 2024, entitled “A Facial Nerve Motion Data Capture System and Method”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of facial paralysis diagnosis technology, and more specifically, to a facial nerve motion data capture system and method. Background Technology

[0004] When diagnosing patients with facial paralysis, doctors need to obtain facial nerve motor data for diagnosis and other procedures. Obviously, the accuracy of the facial nerve motor data used for diagnosis is very important.

[0005] Currently, doctors mainly use visual methods or CTA and MRI scans to detect the movement of the facial nerve in patients with facial paralysis.

[0006] However, due to the limitations of human vision, such as the inability to clearly see high-speed movements like blinking, it is difficult for manual visual methods to capture high-definition details of facial nerve movements in patients with facial paralysis that are invisible to the human eye. Furthermore, because the head position of patients with facial paralysis is not stable, the capture of facial nerve movements is also unstable and heavily reliant on the doctor's subjective experience and ability, thus making the accuracy of doctors' diagnoses of facial paralysis based on the captured information generally unreliable. On the other hand, X-ray scanning methods such as CTA and MRI are harmful to the human body and are suitable for static analysis. When analyzing dynamic scenes of facial nerve movements, the accuracy of diagnosis is also generally unreliable. Summary of the Invention

[0061] It should be noted that the term "comprising" will be used in the embodiments of this disclosure to indicate the presence of the features subsequently declared, but does not exclude the addition of other features.

[0062] When diagnosing patients with facial paralysis, doctors need to obtain facial nerve motor data for diagnosis and other procedures. Obviously, the accuracy of the facial nerve motor data used for diagnosis is very important.

[0063] Currently, doctors primarily use visual methods or CTA and MRI scans to capture facial nerve movements in patients with facial paralysis. However, due to the limitations of human vision, such as the inability to clearly see high-speed movements like blinking, visual methods struggle to capture high-resolution details of facial nerve movements invisible to the naked eye. Furthermore, because the head position of patients with facial paralysis is unstable, the captured information is also inconsistent and heavily reliant on the doctor's subjective experience and ability, resulting in generally low accuracy in diagnosing facial paralysis based on the captured information. On the other hand, CTA and MRI scans are harmful to the human body and are suitable for static analysis; their diagnostic accuracy is also generally low when analyzing dynamic scenarios involving facial nerve movements.

[0064] To address this issue, this disclosure provides a facial nerve motion data capture system and method. This system calibrates the head position of a facial paralysis patient and adjusts the shooting environment to meet target shooting requirements. It records facial nerve motion images of the patient using a designated camera, focusing, and lighting device. This captures details of facial nerve movement that are invisible to the human eye, obtaining stable facial nerve motion image data under stable spatial and head positions. This reduces reliance on the doctor's subjective experience and ability, improves the accuracy of facial paralysis diagnosis, avoids radiation damage, reduces diagnostic costs, and shortens diagnostic time.

[0065] Figure 1 is a structural diagram of a facial nerve motion data capture system according to an embodiment of the present disclosure. As shown in Figure 1, the facial nerve motion data capture system 100 of the present disclosure embodiment may specifically include: a head stabilization device 1, a focusing and illumination device 2, a designated camera 3, and a seat 4.

[0077] Optionally, the facial nerve motion data capture system may also include a camera stand and a seat stand;

[0078] The camera platform is positioned below the designated camera 3 and the focusing and lighting device 2, configured to provide support for the camera and the focusing and lighting device 2 and to change the height of the camera and the focusing and lighting device 2 by lifting and lowering.

[0079] The seat platform is located below the seat 4, configured to provide support for the seat 4 and to change the height of the seat 4 by lifting and lowering it.

[0080] Optionally, the facial nerve motion data capture system may also include a display;

[0081] The monitor is electrically connected to the designated camera 3 and configured to display facial nerve motion images of a facial paralysis patient recorded in real time by the designated camera 3.

[0082] The facial nerve motion data capture system provided in this embodiment includes a seat positioned below a head stabilization device, configured to provide a seat for a facial paralysis patient; a designated camera positioned directly in front of the seat and facing it; focusing and illumination devices symmetrically positioned on either side of the designated camera and facing the seat; a head stabilization device configured to provide support for and calibrate the head position of the facial paralysis patient when the patient sits in the seat; and focusing and illumination devices configured to adjust the shooting environment for the facial paralysis patient to meet the target shooting requirements.

The facial nerve motion data capture system disclosed herein calibrates the head position of facial paralysis patients and adjusts the shooting environment to meet the target shooting requirements. It records facial nerve motion images of facial paralysis patients according to a specified camera and focusing and lighting device. It can capture details of facial nerve motion that are invisible to the human eye. It obtains stable facial nerve motion image data under stable spatial and head positions, reducing reliance on the doctor's subjective experience and ability, improving the accuracy of facial paralysis diagnosis, avoiding radiation damage to the human body, reducing diagnostic costs, and reducing diagnostic time.

[0083] Figure 2 is a flowchart of a facial nerve motion data capture method according to an embodiment of the present disclosure. As shown in Figure 2, the facial nerve motion data capture method of the present disclosure is applied to a facial nerve motion data capture system 100. The facial nerve motion data capture system 100 includes: a head stabilization device 1, a focusing and illumination device 2, a designated camera 3, and a seat 4. The facial nerve motion data capture method of the present disclosure specifically includes:

[0084] S201, when a facial paralysis patient is sitting in a chair, the head position of the facial paralysis patient is calibrated based on the head stabilization device.

[0085] In this embodiment of the disclosure, 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. After the facial paralysis patient sits on the seat 4 of 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.

[0086] S202 uses a focusing and lighting device and a designated camera to adjust the shooting environment for patients with facial paralysis to meet the target shooting requirements.

[0087] In this embodiment of the disclosure, the shooting environment refers to the external environment when shooting a facial paralysis patient, such as light intensity. The target shooting requirement refers to the pre-set requirements for shooting, such as a target shooting requirement of 5000 Lux for light intensity. When the light intensity reaches 5000 Lux, it indicates that the target shooting requirement is met. The shooting environment for the facial paralysis patient is adjusted to meet the target shooting requirement using the focusing and lighting device 2 and the designated camera 3 for subsequent processing.

[0088] S203, in response to the completion of the calibration of the head position and shooting environment of the facial paralysis patient, records the facial nerve motion image of the facial paralysis patient using the specified camera.

[0089] In this embodiment of the disclosure, after calibrating the head position and shooting environment of the facial paralysis patient according to steps S201 and S202, and determining that it is possible to shoot at this time, the designated camera 3 is used to record the facial nerve motion image of the facial paralysis patient.

[0090] It should also be noted that the designated camera 3 for recording facial nerve motion images in this disclosure is a camera whose shooting speed, shooting resolution and noise meet the corresponding parameter standards. In short, it is a high-definition, high-speed and low-noise camera. According to this high-definition, high-speed and low-noise camera, facial details of facial paralysis patients that cannot be captured by the human eye can be captured.

[0091] Optionally, the facial nerve motion images are judged according to preset qualified video standards to filter out unqualified facial nerve motion images, and the facial nerve movements corresponding to the unqualified facial nerve motion images are re-recorded. Qualified video standards include, for example, the patient's face filling at least 50% of the recorded screen area, facial illumination at least 10,000 Lux, no shadows on the patient's face, full facial exposure, and sufficient space between the top of the patient's head and the bottom of their chin from the top and bottom of the recorded screen. When facial nerve motion data does not meet these qualified video standards, it is determined to be unqualified facial nerve data. In this case, the facial nerve movements corresponding to the unqualified facial nerve motion images are re-recorded, i.e., the facial nerve motion images of the patient performing the facial nerve movements are re-recorded.

[0092] The facial nerve motion data capture method provided in this disclosure involves calibrating the head position of a facial paralysis patient while they are seated in a chair using a head stabilization device; adjusting the shooting environment for the patient using a focusing and lighting device and a designated camera to meet the target shooting requirements; and recording facial nerve motion images using the designated camera after the head position and shooting environment calibration are completed. This facial nerve motion data capture method, by calibrating the head position of the facial paralysis patient and adjusting the shooting environment to meet the target shooting requirements using a facial nerve motion data capture system, and recording facial nerve motion images using a designated camera and focusing and lighting device, can capture details of facial nerve motion that are invisible to the human eye. It obtains stable facial nerve motion image data under stable spatial and head positions, reducing reliance on the doctor's subjective experience and ability, improving the accuracy of facial paralysis diagnosis, avoiding radiation damage to the human body, reducing diagnostic costs, and shortening diagnostic time.

[0093] Optionally, as shown in Figure 3, before calibrating the head position of the facial paralysis patient based on the head stabilization device 1, the facial nerve motion data capture method of this embodiment may further include the following steps:

[0094] S301, for a specified camera and seat, determine the horizontal line of the camera frame in the specified camera and the horizontal line of the back panel of the seat.

[0095] In this embodiment of the disclosure, for a specified camera 3, the horizontal line of the camera frame in the specified camera 3 is determined, and for the seat 4, the horizontal line of the back panel of the seat 4 is determined for subsequent processing.

[0096] S302 aligns and calibrates the photographic horizon line and the background horizon line.

[0097] In this embodiment of the disclosure, the 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.

[0098] Thus, a calibration was performed by specifying the horizontal line of the camera frame in camera 3 and the horizontal line of the back panel of seat 4, ensuring a stable spatial position.

[0099] Optionally, the head stabilization device 1 includes a head pressure plate, as shown in Figure 4. The step S201 in the above embodiment, "calibrating the head position of the facial paralysis patient based on the head stabilization device," may specifically include the following steps:

[0100] S401 is based on a head pressure plate to fix the head position of a facial paralysis patient and to provide feedback to the head of the facial paralysis patient by generating force and / or pressure sensations so that the facial paralysis patient can understand the changes in their head position.

[0101] In this embodiment of the present disclosure, the head position of the facial paralysis patient is fixed by the head pressure plate in the head stabilization device 1. The head pressure plate provides feedback to the head of the facial paralysis patient by generating force and / or pressure. The facial paralysis patient can understand the changes in the position of their head based on the feedback from the head pressure plate, such as whether their head has moved.

[0102] S402, for patients with facial paralysis, determine the line connecting the pupils on the face of the patient with facial paralysis, and align and calibrate the line connecting the pupils on the face of the patient with the horizontal line of the back panel.

[0103] In this embodiment, the line connecting the pupils on the face is the line connecting the two pupils on the face of a patient with facial paralysis. The line connecting the pupils on the face of a patient with facial paralysis is determined and aligned with the horizontal line of the backplate in the above embodiment.

[0104] Therefore, a calibration was performed by connecting the pupils of the facial paralysis patient's face with the horizontal line of the backrest of seat 4, ensuring a stable head position.

[0105] Optionally, as shown in Figure 5, step S203 in the above embodiment, "calibrating the head position of the facial paralysis patient based on the head stabilization device," may specifically include the following steps:

[0106] S501 is designed for patients with facial paralysis, and determines multiple pre-set facial nerve movements for them.

[0107] In this embodiment of the present disclosure, the facial nerve movements are pre-configured to judge the facial nerve movements of a facial paralysis patient. The multiple sets of facial nerve movements include multiple eye movements and multiple facial movements. Among them, eye movements include closing the eyes, and facial movements include raising the eyebrows and pursing the lips. For a facial paralysis patient to be diagnosed, the multiple sets of facial nerve movements of the facial paralysis patient are determined for subsequent processing.

[0108] S502 generates corresponding action instructions based on multiple sets of facial nerve movements, so that the facial paralysis patient can perform the specified facial nerve movement corresponding to the action instruction, and records the facial nerve movement image corresponding to the facial nerve movement with a specified camera.

[0109] In this embodiment of the disclosure, the action instruction is the instruction corresponding to each facial nerve action, such as a voice instruction. For example, when the facial nerve action is blinking, the corresponding action instruction can be "Please blink." The designated facial nerve action is the facial nerve action corresponding to the action instruction. For example, when the action instruction is "Please blink," the corresponding designated facial nerve action is blinking. After hearing the action instruction, the facial paralysis patient will blink to complete all facial nerve actions. The facial nerve motion image is the image corresponding to the facial nerve action recorded after the facial paralysis patient makes the facial nerve action. Based on each facial nerve action in the multiple groups of facial nerve actions determined in step S501, a corresponding action instruction is generated so that the facial paralysis patient can make the designated facial nerve action corresponding to the action instruction according to the action instruction. The facial nerve motion image of each facial nerve action in the multiple groups of facial nerve actions is recorded by the designated camera 3.

[0110] It should be noted that the action instructions can not only indicate the corresponding facial nerve movements, but can also include information such as frequency and time, for example, "Please blink 10 times, with a 2-second interval between each blink." This disclosure does not impose further limitations on this. Optionally, during the recording of facial nerve movement images of a facial paralysis patient; when the patient's head position moves, the displacement angle of the patient's head position is determined; in response to the displacement angle not exceeding a preset target displacement angle, the patient is prompted to adjust their head position; in response to the displacement angle exceeding the preset target displacement angle, the facial nerve movement corresponding to the recording process is re-recorded. Wherein, the target displacement angle is the sensitive angle that the human eye can perceive when the head moves; the displacement angle is the displacement angle of the patient's head position along the target axis (e.g., the XYZ axis). For example, the human eye can perceive a head movement at a sensitive angle of 5°. Therefore, the target displacement angle is 5°. When the displacement angle of a facial paralysis patient's head exceeds 5°, it indicates that the patient's head movement is large. In this case, the facial nerve motion image corresponding to the facial nerve movement during the recording process is re-recorded. If the displacement angle of the patient's head does not exceed 5°, a corresponding action instruction can be generated, allowing the patient to adjust their head position according to the action instruction. For example, when the displacement angle of the patient's head does not exceed 5°, the corresponding action instruction is generated as "turn slightly to the right" to guide the patient to adjust their head position.

[0111] Optionally, before recording facial nerve motion images of a facial paralysis patient using the designated camera 3, the target imaging mode of the designated camera 3 is determined based on the facial nerve movements; the imaging mode of the designated camera 3 is then adjusted to the target imaging mode. The target imaging mode includes high-speed imaging and low-speed imaging. For example, when the facial nerve movement is an eye movement, such as closing the eyes, a high-speed mode is needed to capture details of the patient's eyes that are invisible to the human eye; that is, the designated camera 3 is switched to high-speed imaging mode. However, when the facial nerve movement is a facial movement, such as pursing the lips, such a high shooting speed is not required for eye movements; in this case, it is sufficient to switch the designated camera 3 to low-speed imaging mode.

[0112] Optionally, the shooting environment includes at least shooting parameters and illuminance parameters; illuminance parameters include at least light intensity; shooting parameters include at least depth of field and pixel density.

[0113] The system acquires shooting experiment data based on a preset shooting algorithm; obtains target shooting parameters for a designated camera 3 and target illuminance parameters for a focusing and lighting device 2 based on the preset shooting experiment data; adjusts the shooting parameters of the designated camera 3 based on the target shooting parameters, and adjusts the illuminance parameters of the focusing and lighting device 2 based on the target illuminance parameters. The shooting algorithm is a pre-set shooting algorithm, and the target shooting parameters include at least shooting speed, aperture value, and focal length value; the target illuminance parameters include at least light intensity.

[0114] It should be noted that the explanations and descriptions of the above embodiments also apply to the facial nerve motion data capture method of the embodiments of this disclosure, and the specific process will not be repeated here.
