Before calibration, you need to determine the axis direction. The set calibration axis will determine the upward axis (Z or Y) in the Global Coordinate System after calibration. Set the type of L-bar according to the length of the L-bar you are using. If you are unsure about the type of L-bar, you can consult our technical engineers.
Click on the "Calibration Pane" in the toolbar at the top of the window. In the calibration window, click the gear icon. Under the "Frame" option, confirm the needed coordinate system definition. You can choose whether the coordinate system is Z-axis up or Y-axis up using the "Up Axis" (5.1.2). In the "L-Frame Type" option, select the corresponding L-Type. The L-Type corresponds to the purchased L-Type rod. The size of the L-Type rod can be determined by measuring the distance between the two marker points at the farthest end of the long side of the L-Type rod. For example, if the distance between the two marker points at the farthest end of the long side of the L-Type rod is approximately 600mm, then the type of L-Frame you are using is "L-600". The last letter in the L-rod type indicates the following: S represents a soft L-rod, R represents a rigid L-rod (default is rigid), and FP represents applications related to force platforms.You can also customize the L-bar type. Select "Manual" from the dropdown menu. Customization requires you to manually enter the X, Y, and Z coordinates of each marker ball in the "Coordinates" table below.
3.Camera Installation Orientation Setup: Before calibration, it is necessary to configure the installation orientation of the camera. By default, the cameras are set to the standard upright position. However, if some cameras are installed in an inverted or sideways position, the corresponding installation parameters must be set prior to calibration.
4.Parameter Settings for Ending Single-Camera Swing in T Calibration: The T calibration will only end when the number of valid frames collected by the camera exceeds the threshold set here. Otherwise, the T calibration process will remain at 99%, waiting for the number of frames collected by the camera to reach the threshold.
5.Coordinate System Switching: After loading the calibration file, you can switch between the Z-axis and Y-axis through the calibration axis in the calibration settings. After switching the axis, the software automatically retains the calibration file.
