Hello mohmad,
It seems that the coordinate data loaded to the Reference pane is incorrect, so when PhotoScan is trying to use this data to georeference the model it is trying to move all the cameras to the same point.
Please perform the following steps in Professional edition:
- select all cameras in the Reference pane,
- right-click on selection and choose Clear option,
- go to Reference pane setting dialog and switch the coordinate system to Local Coordinates,
- then right-click on the chunk's label in the Workspace pane and choose Reset Transform option.
However, the alignment may be still unstable, due to the lack of the texture pattern on the object's surface and ineffective use of the image frame space.
