（Ⅰ） Create a human body model

Markerless Body (22):

1. After calibration is completed, the model walks into the venue, and 22 white unnamed points will be displayed in the 3D view.

2. The model stands in the negative direction of the Z-axis in an A-Pose. Click the Freeze Frame button at the bottom of the interface, right-click in the 3D view to create a human body, select "MarkerlessBody(22)" from the model dropdown menu, enter the name of the created human body, and click Create.

Create a Face Recognition Template:

1. Face recognition is used in multi-human movement scenarios to prevent incorrect recognition of human templates when a person leaves the venue and re-enters.
2. First, enable the face recognition function in the recording settings and select "Input". The model stands in front of the first camera (the first camera displayed in the view after opening the reference video), facing the lens to ensure clear visibility of the face, and must ensure there is only one face. After clicking "Input" and checking that the image is correct, a pop-up window will prompt you to enter the face name.

3. The model stands in the negative direction of the Z-axis in an A-Pose. Click the "Freeze Frame" button at the bottom of the interface, right-click in the 3D view to create a human body, select "Markerless Body(22)" from the model dropdown menu, enter the name of the created human body, select the bound face information from the dropdown menu, and click "Create".

4. When a human body leaves the venue and re-enters, it is necessary to face the first camera directly within the viewing angle of all lenses, and there must be only one face for human template recognition.

tip

If only one human body appears in the venue with white dots and only one template is selected in the assets, face recognition is not required, and it will be directly recognized as that template. In other cases, matching is done according to the template bound to the face name. When matching faces, the face must be directly facing the camera, and only one person should be unmatched with a template.

Markerless Body+Hand（22）:

1. The software supports creating human body models by accessing third-party glove devices in real time.

2. To use glove devices in Astra, you need to first connect the gloves in the third-party glove software. Open the glove management window. Take the "Vrtrix" glove as an example for introduction:

3. Connection Queue and Device List: In the glove management window, select "Vrtrix" as the type, leave other options unchanged, and click "+" to add a glove connection. The connection queue will display the "network address, port, type, status, version, and limit quantity" of the connected gloves. Meanwhile, the device queue below will show the "serial number, brand, connection status, hand type, battery level, and signal strength" of the left and right hands of the gloves. Select a connected queue and click "X" on the right to delete the queue. If the glove is not powered on or not properly connected, the connection status and parameters of the glove will not be displayed in real time in the connection queue and its device list after adding the glove connection.

   

4. In the binding module on the right side of the window, select the corresponding serial numbers for the left and right gloves. The serial numbers of the left and right gloves can be viewed in the "Serial Number" column of the device queue. If multiple pairs of gloves are connected, pay attention to distinguishing the serial numbers when binding the left and right hands. i. Enter a custom name in the binding module, and click "+" on the right side of the binding set to add a glove binding set. Each binding set will display the "ID, name, left-hand serial number, and right-hand serial number" of the current glove set. When adding multiple glove sets, the IDs will be arranged in sequence. iii. When adding binding sets for multiple pairs of gloves, pay attention to distinguishing the names and ensuring that the serial numbers of the left and right hands are correctly bound.

5. The model stands in the negative direction of the Z-axis in an A-Pose. Click the "Freeze Frame" button at the bottom of the interface, right-click in the 3D view to create a human body, select "Markerless Body+Hand(22)" from the model drop-down menu, enter the name of the created human body, select the serial number, and click "Create". If multiple pairs of gloves are added, pay attention to distinguishing the serial numbers to avoid incorrect selection.
