[Purpose]
In this step, the calibration grid is installed within the camera FOV and the position of the calibration grid (where it is installed) is set.
The position of the calibration grid does not need to be recorded to a User Frame since 'Measure automatically' was selected in the previous step for 'Setting Cal. Grid Pos. Method'.
[Procedure]
- Place the calibration grid ((1) on the upper-right figure) in the camera FOV.
- Place the calibration grid so that the grid pattern covers the entire camera FOV. As long as about 4 x 4 circles, including the four large circles around the center, are in the FOV, circles in the periphery can be outside the FOV.
- Do not move the calibration grid until the camera calibration is complete and everything has been saved.

TP
Select the tool frame to which the TCP for the touch-up pointer is set. In this tutorial, Tool Frame 2 is used.
Since the calibration grid's position will be measured automatically in the next steps, there is no need to use the 4-Point Method to teach the grid manually with a robot-mounted camera.
Additional
On the calibration grid, large circles are arranged side by side in an L shape.
Three large circles are placed in line from the corner point of the L shape in the X-axis direction while two large circles in the Y-axis direction.
