[Cause]
iRCalibration 's visual measurement error. The camera and target distance exceeds the " camera distance range" set on the visual settings. That is to say, the camera and the target are closer to each other than when teaching models.
[Countermeasure]
The response is through the following steps.
・ Check the distance between the camera and target at the measurement start position. If the camera and target are too close, reteach the measurement start position to increase the distance between them. Alternatively, reteach the model using the distance between the camera and target at the measurement start position.
・ If the above countermeasures are ineffective, expand ‘Camera distance range’.
