Auto 3D measurement with Shining 3D Scanner

March 30, 2011 - PRLog -- It is an automotive engineering research which is founded in 1995. It is also one of the first national identification enterprises of technology centers. This company has a scientific R&D team with more than 3000 people, more than 200 of which are senior specialists. As the independent innovation of car groups, the automotive engineering institute already has strong capacity on independent research and development. It owns the ability of automobile modeling design, engineering design, simulation analysis, test development and evaluation and prototype trial. Thanks to its domestic leading automotive emission, environmental laboratory, first-class processing center and testing methods, the company has assumed many national 863 significant scientific research projects.

Customers buy Shining3D products for applying in the areas of auto 3D measuring, quality inspection, aerodynamic simulation analysis, 3D design and database modeling.

According to customers' requirement, the overall measurement accuracy should be controlled within 0.1mm in the process of auto 3D digitalized and 3D digital model accumulation.

Shining3D design the solutions with equipments：Shining3D Photogrammetry,  Shining3D Scanner, Shining Form XOR.

Operation flow

1.Arrangement of scanning site：

Place the tested vehicles in capacious and bright easy operation places.                    
Then begins the vehicle processing: spraying imaging agents, pasting index point and placing benchmark.  

2. Frame point extraction with Shining3D-Photogrammetry
 
We extract frame points by shooting from different angles of the tested vehicle with the usage of digital camera.
 


3.Calculation of all the frame points

First, import the pictures into software of Shining3D-Metric. Then calculate to obtain the frame points of measured vehicle according to triangle measuring principle.

We import data of framework points into Shining3D-Scanner to 3D scan. Then we take the points data as skeleton to 3D data registration. Thus eliminate the accumulative error effectively and improve the accuracy of data measurement.


4.Automotive body scanning with Shining3D-Scanner


We use Shining3D - Metric system to frame points calculate. Since located, we begin the whole vehicle scanning to obtain part and whole 3D vehicle data with the help of Shining3D-Scanner.

Conclusion：
1.Scanning time: the 3D measuring time of a car is half a day, and the measuring efficiency is greatly increased comparing with traditional three coordinates measuring method.
2.Measurement accuracy: Its accuracy is controlled within 0.1mm and exactly meets customers’ requirements.
3.Way of measurement: Shining3D-Scanner adopts mode of surface scanning. And its body data will be more complete and benefit to later retrofit design comparing with traditional three coordinates machine dot way.

Subsequent applications:

1.Auto body design
2.Rapid prototyping of car model
3.Quality control in automotive manufacturing
