After the subway car manufacturing, due to the large front surface area, traditional test methods can’t achieve the quality control and verification, and the key parts deformation cannot be detected.
How SCANTECH deal with it?？
Global position and then scan
As the subway deformation, using the MSCAN to obtain its space anchor point. Cooperate with HSCAN331 to obtain 3d data. Comparison data with its 3d digital model and analyze deformation and adjust the product.
Needed working time for MSCAN and HSCAN
10 minutes for post mark points
5 minutes for MSCAN
10 minutes for scan
Using Global MSCAN to obtain mark points’ space coordinates and the control the global error in 0.025mm/m
3d digital analog comparison result
Cooperating of HSCAN and MSCAN help customer to deal the question of large piece object detect.
