官方故障排除步骤
Cause: Focal distance and Z distance could not be calculated. When optical axis of camera is perpendicular to plate, focal distance and Z distance cannot be calculated accurately. Remedy: In the case of a robot-mounted camera is used or when the calibration grid plate is mounted on the robot end of arm tooling, 2-plane calibration should be done. In the case of lens which projects orthogonally as telecentric lens, set Projection to Orthogonal and retry calibration. In other case, set Override Focal Distance to Yes and Focal Dist to the value of nominal focal distance of the lens, and retry calibration. When the situation is not improved even if the actions above are taken, Contact your local FANUC representative.
