2. Calibration Preparation
Click the drop-down list above the main view. Select "2D Camera View" from the drop-down list to switch the main view to 2D view. You can display the imaging status of each camera by clicking "Show All Cameras" at the top of the interface, allowing you to see the reflections and noise points of each camera in Live (5.2.1).\
In the 2D view, right-click and select "Show Grayscale" to open the grayscale image. You can also use the shortcut button in the toolbar above the view to open a camera's grayscale image.
If you need to capture a grayscale image from a single camera, switch to the single camera display and click the camera button. After capturing, the software will display a popup window showing the save path (5.2.2).\
In the 2D view, right-click to select and display each camera's IP address.
Prepare the L-shaped calibration rod (5.2.3) and the T-shaped calibration rod (5.2.4). First, place the L-shaped calibration rod in the center of the motion capture field.\
Adjust the position of each camera by adjusting the three-way gimbal. Usually, the four marker points on the L-shaped calibration rod are positioned slightly below the center of the camera (to ensure that each camera has a large enough observation range in both horizontal and vertical directions) (5.2.5). You can also place some reflective markers at the edges of the required capture area according to the actual activity range of the specific object being captured, which can more intuitively reflect the area seen by the camera (the range that each camera can actually capture can be seen from the captured multiple edge points, so the camera can be adjusted more accurately to make the entire system capture a larger and more stable range).\
Refer to section "Ⅷ. Calibration Categories" in this manual to select the appropriate type of calibration. Generally, basic calibration is sufficient.
