[3D Setting: World Coordinates (3D Camera Image)]

Create a conversion parameter by photographing calibration target and performing sampling measurement at several points. Use this parameter to convert the [Measurement] in the image photographed with the camera to actual dimensions in the world coordinate (spatial coordinate).
The method of the measurement using a white circle outline at the center of the calibration target is described below.
  1. Tap [3D setting] in the "Item tab" area (top) and tap [World coordinates] in the "Item tab" area (bottom).

  2. In the "Sampling condition" area, tap [...] for "Repetition frequency" and enter a value.
    For how to input value, see User's Manual, "Inputting a Value"

  3. Photograph the calibration target with the camera.
    The relatively large white circle outline printed at the center of calibration target is the sampling target.
  4. In the "Point" area, tap [Measure].
    3D Setting (World coordinates) - Point Area
    The circle at the center of calibration target is measured with each camera. Coordinate calculation is performed based on the measurement result.
    The Coordinate Setting window is displayed. The measurement coordinates and world coordinates are displayed in the Coordinate Setting window.
    Note
    • If the center circle cannot be found correctly, it may be easier to find if you measure after enclosing the center circle in an area that is inside all cameras in the Region setting.
  5. Change the world coordinate (spatial coordinate) as necessary and tap [OK].
    Coordinate Setting window
    Point coordinate is displayed at "Point".
  6. Move the calibration target and repeat the Steps 4 and 5 twice.
    Register three points for "Point".

    Note
    • To delete a registered point, select the point to delete from the list and tap [Delete].
  7. After three points (No. 0 to 2) are entered in "Point", tap [Parameter making].

    Note
    • This button is enabled only when three points are registered for "Point".
    Parameter creation is performed. The result is displayed as a message.
    When parameter creation is successful, a value is displayed in "Parameter".
