techinical requirement
The overall precision should be controlled in 0.1mm when obtaining model of auto vehicle inner frame 3D.
 
Solution
Equipments:：Shining3D-Photogrammetry+Shining3D-Scanner+ ShiningForm XOR

Operation flow (Workflow)

1. Arrangement of scanning field

Place the tested vehicles in workshop or outdoor easy operation places.

Vehicle processing: imaging agents spraying, reversible pasting and benchmarking placing.
 

2.Photography with the usage of Shining3D-Photogrammetry

We extract frame points by shooting from different angles of vehicle with the usage of digital camera that supplied by Shining3D-Photogrammetry.
 

3.Internal framework points calculated by Photogrammetry software

Import the pictures into Shining3D-Metric software and calculate to achieve the vehicle frame points according to the triangle measuring principle.

4.Whole vehicle frame scan with the usage of Shining3D-Scanner

We first use Shining3D-Metric system to achieve a more accurate overall coordinate data, which is then be imported into.Shining3D-Scanner for 3D scanning. At last we eliminate the cumulative registration error and optimize the whole data in the overall coordinate system.
（The pictures are for parts scanning）

Conclusion
1. Scanning time: Time of 3D measurement for vehicle frame is approximately 1 day. Measurement efficiency is greatly increased compared with traditional three coordinates measurement method.
2. The measurement accuracy: The overall accuracy controlled in 0.1mm with the error comparison of high precise tri-ordinate measuring machine. It fully meets customers’ requirement.
