Scantech how to 3d reconstruct the object as big as a helicopter
3D scanning technology changes the world
A small detail in the development of helicopters may cause the development process to stagnate or the equipment performance is not up to the standard. Therefore, a high-precision three-dimensional data acquisition method greatly contributes to the reverse of the helicopter, helping developers to better understand the design concept, technical details and technical route.
Customer: A College of engineering
Scanning object: The whole helicopter
Scanning device: HSCAN771 Handheld 3D scanner & MSCAN photogrammetry system
Scanning requirements: Obtain complete and high precision 3d model of the whole machine.
Aim: It provides data support for the subsequent modification of helicopters and improves a more intuitive and comprehensive understanding of helicopter development so as to obtain scientific progress.
How big is the helicopter for scanning this time?
Body length: 9m; rotor blade deployment length: 13.5m, fuselage height: 4m; as the following picture:
Why make 3D measurement of a helicopter?
College of engineering need to reverse the entire aircraft, on the one hand to modify it. On the other hand, through the reverse process, the helicopter design has a deeper understanding and progress in scientific research.
What are the difficulties of 3D scanning in helicopters?
The aircraft is large in size, and it is difficult to measure with ordinary 3d measuring equipment. For example, the photogrammetry 3d scanner has poor portability and limited field of vision, so it is difficult to obtain complete 3d data of the aircraft at one time. Therefore, a portable and efficient 3d measurement method is needed.
HSCAN771 3d scanner with smart technology worked with MSCAN global photogrammetry system can quickly obtain 3d data of aircraft surface. Whether it is large curved body or small cabin, HSCAN771 can be easily scanned and complete 3d model of the whole machine can be obtained at one time.
3D measurement solution
Based on the demand assessment of the 3d measurement of the helicopter and considering the size and precision requirements of the aircraft, Scantech adopted the measurement scheme of HSCAN771 3d scanner with scanning speed up to 480,000 measurements per second worked with MSCAN global photogrammetry to carry out the 3d measurement of the helicopter.MSCAN global photogrammetry can greatly improve the volume precision in the process of 3d scanning, and the accuracy is as high as 0.02mm+0.025mm/m, so that the 3d measurement accuracy of the whole machine and parts can reach the expected effect of customers.
