[0002] Human motion capture is a key supporting technology in fields such as virtual reality, human-computer interaction, motion analysis, and film and television production. Current motion capture solutions typically involve deploying multiple cameras within a motion capture space, capturing motion by identifying the target's limbs or markers on their body.

[0003] However, this motion capture method requires the deployment of multiple cameras and may have blind spots, meaning that some areas may not be captured. This is especially true for capturing large-scale movements, which results in high implementation costs and limited shooting range. In addition, since cameras need to be placed in the capture space, the space used is fixed and needs to be deployed in advance, which leads to complex deployment and low flexibility of use.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The following is combined with Figure 1 and Figure 2 This invention describes a head-mounted human motion capture device, comprising: Helmet body 100; At least one panoramic shooting module 200 is mounted on the helmet body 100; A processing module 300 is disposed on the helmet body 100, and the processing module 300 is electrically connected to the panoramic shooting module 200; A first wireless communication module 400 is disposed on the helmet body 100. The first wireless communication module 400 is electrically connected to the processing module 300. The first wireless communication module 400 is used to communicate with an external terminal to transmit data including images.

[0023] In the above embodiment, by providing at least one panoramic shooting module 200 on the helmet body 100, the panoramic shooting module 200 can capture images including the wearer of the helmet body 100 and the surrounding environment using its 360° shooting angle range. The processing module 300 processes the images captured by the panoramic shooting module 200 to form image data, which is then transmitted to an external terminal through the first wireless communication module 400 for further processing and display to achieve the purpose of motion capture.

[0024] Therefore, by setting a panoramic shooting module 200, a processing module 300 and a first wireless communication module 400 on the helmet body 100, there is no need to fix the camera externally. The user only needs to wear the helmet body 100 to perform motion capture, which helps to simplify deployment and reduce motion capture costs. It also makes the helmet more portable and improves the freedom and flexibility of use. At the same time, the panoramic shooting angle above the head can continuously shoot the wearer as the motion capture target, avoiding the problem of blind spots and improving the reliability of motion capture.

[0025] It is understood that the head-mounted human motion capture device provided by this utility model can not only capture the motion of the wearer of the helmet body 100, but also, in some embodiments, capture the motion of people other than the wearer, so as to improve the shooting flexibility and freedom of motion capture.

[0026] In some embodiments of this utility model, the processing module 300 may include a device or circuit module with processing functions, such as a microcontroller or embedded chip. In some embodiments, the processing module 300 may perform preprocessing such as distortion correction on the panoramic image of the panoramic shooting module 200 to facilitate subsequent processing by an external terminal.

[0027] In some embodiments of this utility model, the first wireless communication module 400 may include implementations of circuit modules or devices with wireless communication functions such as WIFI modules and ZIGBEE modules.

[0028] It is understandable that motion capture requires processing such as motion change recognition and 3D modeling, which places high demands on processing performance and necessitates the use of an external terminal. In some embodiments of this invention, after acquiring image data, the external terminal can use common image recognition processing methods to identify key points of the human body in the image, such as arms and joints, to establish the 3D coordinates of these key points in the shooting coordinate system. Then, after transformation processing, the 3D coordinates of the key points are converted to the global coordinate system. Based on the changes in the global coordinates of the key points, the motion capture and recognition of the human body are achieved, thus achieving the effect of motion capture. In some embodiments, the 3D coordinates of the key points in the shooting coordinate system can also be determined by identifying reflective markers worn by the human body in the image.

[0029] In the above embodiments, compared to motion capture methods that involve setting up multiple cameras in the capture space, only a small number of panoramic shooting modules 200 need to be set on the helmet body 100 to capture the wearer from all directions, which can meet the needs of motion capture. This effectively reduces the number of shooting devices required for motion capture. Furthermore, the shooting points move with the wearer, meaning the shooting direction is fixed relative to the wearer, which simplifies subsequent coordinate transformation processing. Only the global coordinates of the helmet body 100 need to be determined, and the three-dimensional coordinates of the key points of the wearer's body can be transformed into the global coordinate system based on the relative position of the helmet body 100 and the wearer. At the same time, reducing the number of shooting points can reduce the complexity of collaborative processing of multiple shooting points.

[0030] In some embodiments of this utility model, a detachable fixing structure, such as a sliding buckle or a plug-in buckle, can be provided between the helmet body 100 and the panoramic shooting module 200 to facilitate the replacement of different types of panoramic shooting modules 200. For example, it can be replaced with an infrared panoramic camera to facilitate the shooting of reflective markers worn on the human body; or it can be replaced with a visible light panoramic camera, etc., which makes the use more flexible and convenient and meets the needs of different usage scenarios. In some embodiments of this utility model, the panoramic shooting module 200 can also be an integrally integrated structure set on the helmet body 100.

[0031] refer to Figure 1 and Figure 2 In some embodiments of the head-mounted human motion capture device of this utility model, a motion sensing module 500 is also included. The motion sensing module 500 is disposed on the helmet body 100, and the processing module 300 is electrically connected to the motion sensing module 500. The motion sensing module 500 is used to detect the motion changes of the helmet body 100.

[0032] In the above embodiment, a motion sensing module 500 is provided on the helmet body 100 to detect changes in the movement of the helmet body 100. Since the helmet body 100 and the wearer's head are relatively fixed, the changes in movement can be considered as changes in the wearer's head movement, which are also related to changes in the wearer's body displacement. When transmitting image data, the processing module 300 also transmits the motion detection data of the motion sensing module 500 to an external terminal. The external terminal, by combining the image data and the motion detection data, can more accurately identify changes in the wearer's movements, which helps to make motion capture more accurate and reliable.

[0033] In addition, the motion sensing module 500 detects the motion changes of the helmet body 100, which makes it easier to determine the global coordinate changes of the helmet body 100 in the global coordinate system more accurately.

[0034] refer to Figure 1 In some embodiments of the head-mounted human motion capture device of this utility model, the motion sensing module 500 includes a visual inertial odometer, which is electrically connected to the processing module 300 and is disposed on the side of the helmet body 100.

[0035] Visual-Inertial Odometry (VIO) comprises a camera and an Inertial Measurement Unit (IMU). While the IMU detects motion changes, using it alone can lead to drift due to accumulated sensor errors. By acquiring visual information through a camera, accurate pose constraints can be provided, effectively correcting the IMU's biases and suppressing their accumulation that causes drift. Therefore, VIO provides more stable motion detection, improving the reliability of detecting motion changes in the helmet body.

[0036] Visual inertial odometry (VIO) generates inertial attitude data to reflect the motion changes of the helmet body 100. In scenes with blurred panoramic images, the inertial attitude data provides redundant information, ensuring the continuity of motion recognition during motion capture. Subsequent external terminals, combining panoramic image data and inertial attitude data, can more accurately and reliably capture the wearer's motion, thus improving the accuracy of motion capture.

[0037] Since visual inertial odometry requires visual information obtained through a camera for correction, placing the visual inertial odometry on the side of the helmet makes it easier to capture feature points for correction without affecting the panoramic shooting module 200.

[0038] In some embodiments of this utility model, the motion sensing module 500 may also be an implementation of devices or modules such as accelerometers and gyroscopes that can detect changes in the motion of the helmet body 100.

[0039] refer to Figure 1 In some embodiments of the head-mounted human motion capture device of this utility model, at least one of the panoramic shooting modules 200 is disposed on the front side of the helmet body 100, and the shooting range of the panoramic shooting module 200 includes the wearer of the helmet body 100.

[0040] In the above embodiment, by setting the panoramic shooting module 200 on the front side of the helmet body 100, the wearer of the helmet body 100 is photographed from the front side of the helmet body 100, generating an image including the front of the wearer, which facilitates motion capture of the wearer's whole body including the legs, and further improves the integrity of motion capture.

[0041] In some embodiments of the head-mounted human motion capture device of this utility model, two panoramic shooting modules 200 are provided, one of which is located on the front side of the helmet body 100, and the other panoramic shooting module 200 is located on the rear side of the helmet body 100.

[0042] In the above embodiment, by simultaneously providing panoramic shooting modules 200 on the front and rear sides of the helmet body 100, the wearer can be photographed from the front and rear sides of the helmet body 100 at the same time, generating images including the wearer's front and back, which is beneficial for capturing the wearer's whole body in all directions, thereby achieving all-round motion capture of the wearer and further improving the integrity of motion capture.

[0043] In some embodiments of this utility model, a panoramic shooting module 200 may be provided at the top center of the helmet, so that a single panoramic shooting module 200 can simultaneously capture the front and back of the wearer, which is suitable for usage scenarios where less attention is paid to the wearer's leg movements.

[0044] refer to Figure 1In some embodiments of the head-mounted human motion capture device of this utility model, the panoramic shooting module 200 includes an extension rod 210 and a panoramic camera 220. One end of the extension rod 210 is connected to the helmet body 100, and the panoramic camera 220 is disposed at the other end of the extension rod 210 away from the helmet body 100.

[0045] In the above embodiment, the panoramic shooting module 200 includes an extension rod 210 and a panoramic camera 220. The extension rod 210 moves the panoramic camera 220 away from the helmet body 100, making it easier for the panoramic camera 220 to capture the wearer's body. In other words, the shooting angle of the panoramic camera 220 covers more of the wearer's body, increasing the proportion of the wearer's body in the captured panoramic image. This allows for clearer observation of changes in the wearer's body, improving the accuracy of motion capture.

[0046] In some embodiments of this utility model, a panoramic shooting module 200 is provided on both the front and rear sides of the helmet body 100, and the panoramic shooting module 200 includes an extension rod 210 and a panoramic camera 220, so that the front and back images of the wearer can be captured more completely and clearly from the front and rear sides of the helmet body 100, thereby improving the completeness of the wearer's motion capture.

[0047] In some embodiments of this utility model, in order to protect the panoramic camera, a hemispherical transparent shell may also be included. The hemispherical transparent shell is connected to the extension rod 210 to form a cavity covering the panoramic camera, thereby protecting the panoramic camera and improving the reliability of the structure.

[0048] refer to Figure 1 In some embodiments of the head-mounted human motion capture device of this utility model, the extension rod 210 is provided with an operation key group 211, which is electrically connected to the panoramic camera 220.

[0049] By providing an operation key group 211 on the extension rod 210, the wearer can quickly adjust the shooting of the panoramic camera 220 through the operation key group 211, such as adjusting the shooting parameters of the panoramic camera 220, such as the sensitivity and resolution, so as to make operation and use more convenient and quick.

[0050] refer to Figure 1 In some embodiments of the head-mounted human motion capture device of this utility model, the processing module 300 is disposed inside the helmet body 100, and the helmet body 100 is provided with a heat dissipation hole group 110, the position of the heat dissipation hole group 110 corresponding to the position of the processing module 300.

[0051] In the above embodiment, the processing module 300 is disposed inside the helmet body 100, which can prevent the processing module 300 from being damaged by collision. The processing module 300 generates heat during operation. By providing a heat dissipation hole group 110 on the helmet body 100, the heat can be dissipated from the inside of the helmet body 100 to the outside, which helps to improve the heat dissipation effect of the processing module 300 and at the same time helps to reduce the temperature of the helmet body 100, prevent the helmet body 100 from becoming too hot, and improve the wearing experience of the wearer.

[0052] In some embodiments of this invention, the first wireless communication module 400 and the motion sensing module 500 are disposed inside the helmet body 100, which can protect the first wireless communication module 400 and the motion sensing module 500 from collision damage, thereby improving the reliability of use. The heat dissipation hole group 110 can also promote the heat dissipation of the first wireless communication module 400 and the motion sensing module 500, and the heat dissipation hole group 110 can make it easier for the wireless signal of the first wireless communication module 400 to be transmitted to the outside, which is conducive to making the communication more stable and reliable.

[0053] refer to Figure 2 In some embodiments of the head-mounted human motion capture device of this utility model, an energy storage power supply module 600 is also provided on the helmet body 100. The energy storage power supply module 600 is electrically connected to the panoramic shooting module 200, the processing module 300 and the first wireless communication module 400 respectively.

[0054] In the above embodiments, by providing power to the panoramic shooting module 200, processing module 300 and first wireless communication module 400 by setting an energy storage power supply module 600 on the helmet body 100, independent operation can be achieved without relying on external power supply, which is beneficial to improving the convenience and flexibility of use.

[0055] It is understood that in embodiments where the motion sensing module 500 is provided, the energy storage power supply module 600 is electrically connected to the motion sensing module 500 to supply power to the motion sensing module 500.

[0056] In some embodiments of this utility model, in addition to the implementation method of power supply by energy storage power supply module 600, power supply can also be carried out by wired power supply.

[0057] In some embodiments of the head-mounted human motion capture device of this utility model, the energy storage power supply module 600 includes a battery, a power supply circuit, a charging circuit, and a charging port, all disposed on the helmet body 100. The battery is electrically connected to the power supply circuit and the charging circuit respectively. The power supply circuit is electrically connected to the panoramic shooting module 200, the processing module 300, and the first wireless communication module 400 respectively. The charging port is electrically connected to the charging circuit.

[0058] In the above embodiments, the battery supplies power to the panoramic shooting module 200, the processing module 300, and the first wireless communication module 400 through the power supply circuit. When the battery power is insufficient, it can be connected to the power supply through the charging port so that the power supply can charge the battery through the charging circuit.

[0059] In some embodiments of this utility model, the energy storage power supply module 600 may also include a battery, a power supply circuit, and a wireless charging circuit. The battery supplies power to the panoramic shooting module 200, the processing module 300, and the first wireless communication module 400 through the power supply circuit.

[0060] The following describes a motion capture system provided by this utility model. The motion capture system described below can be referred to in correspondence with the head-mounted human motion capture device described above.

The second wireless communication module 710 is electrically connected to the edge processing unit 720, and the edge processing unit 720 is connected to the display screen 730. The first wireless communication module 400 is communicatively connected to the second wireless communication module 710 to transmit image data.

[0062] In the above embodiments, the present invention provides a head-mounted human motion capture device as a data acquisition end. A person wears a helmet 100 as the wearer to perform motion capture. By providing at least one panoramic imaging module 200 on the helmet 100, the 360° shooting angle range of the panoramic imaging module 200 can capture images including the wearer of the helmet 100 and the surrounding environment. The processing module 300 processes the images captured by the panoramic imaging module 200 to form image data, which is then transmitted via the first wireless communication module 400. In the processing and display terminal 700, the edge processing unit 720 acquires the transmitted image data via the second wireless communication module 710 for further processing to achieve the purpose of motion capture. The edge processing unit 720 displays the motion capture data on the display screen 730 for easy confirmation of the motion capture results.

[0063] Therefore, by setting a panoramic shooting module 200, a processing module 300 and a first wireless communication module 400 on the helmet body 100, there is no need to fix the camera externally. The user only needs to wear the helmet body 100 to perform motion capture, which helps to simplify deployment and reduce motion capture costs. It also makes the helmet more portable and improves the freedom and flexibility of use. At the same time, the panoramic shooting angle above the head can continuously shoot the wearer as the motion capture target, avoiding the problem of blind spots and improving the reliability of motion capture.

[0064] In some embodiments of this invention, the edge processing unit 720 may include implementations of devices with processing functions such as a central processing unit and an image processor. In some embodiments, the edge processing unit 720 may store image processing models, neural network models, etc., to process panoramic images to achieve motion capture.

In some embodiments, the first wireless communication module 400 and the second wireless communication module 710 may communicate and transmit based on the WIFI 6E protocol.

[0066] In some embodiments of this utility model, a visual inertial odometer is provided on the helmet body 100, and the operation process of the above-mentioned motion capture system is as follows: The panoramic imaging module 200 on the helmet body 100 continuously captures panoramic images, such as... Figure 3 As shown, the inertial measurement unit in the visual inertial odometry simultaneously detects and generates initial inertial detection data in real time; Visual inertial odometry integrates visual information captured by a camera with initial inertial detection data to determine the inertial attitude data of the helmet body 100, reflecting the current pose of the helmet body 100. The processing module 300 sends the panoramic image and inertial attitude data through the first communication module; In the processing display terminal 700, the edge processing unit 720 acquires panoramic images and inertial attitude data through the second communication module; The edge processing unit 720 processes the panoramic image using an image processing model, such as the YOLO model, to detect and locate the human body bounding box. The edge processing unit 720 combines human body bounding box and inertial attitude data to dynamically acquire data by human body region and convert it into a virtual pinhole camera perspective view. The edge processing unit 720 inputs the perspective view into the spatiotemporal Transformer network and outputs the three-dimensional coordinates of 17 key points, corresponding to the human skeleton topology, to reflect the human body's movements. The edge processing unit 720 performs panoramic coordinate transformation based on inertial attitude data, mapping the three-dimensional coordinates of key points in the shooting coordinate system to the global coordinate system. Based on the changes in the global three-dimensional coordinates of the key points, motion capture data is generated, which can reflect the changes in human motion and achieve the purpose of motion capture. The edge processing unit 720 displays the motion capture data through the display screen 730 to intuitively show the results of the motion capture.
