I will introduce two methods of reverse engineering based on 3D scan data.
There are various methods for reverse engineering, and the choice of method affects the output data. Therefore, it is necessary to select the optimal method according to the purpose of data use and required accuracy. We will introduce two methods of reverse engineering based on 3D scan data, along with their procedures and characteristics. <Reverse Engineering Based on Cross-Sectional Contour Shape> [Step 1] Acquisition of shape data (point cloud data) using a laser scanner. [Step 2] Polygonization and mesh correction. [Step 3] Modeling is performed using 3D modeling software and 3D CAD software. A sketch of the cross-section is created on a reference plane, and solid shapes are generated using functions such as extrusion and rotation. <Reverse Engineering Based on Surface Shape> [Step 1] Acquisition of shape data (point cloud data) using a laser scanner. [Step 2] Polygonization and mesh correction. [Step 3] Modeling is performed using 3D modeling software and 3D CAD software. A surface that fits the mesh to the surface shape is created for all surfaces to generate a solid shape.

basic information
In reverse engineering based on the contour shape of the cross-section, the modeling is done with geometric shapes, resulting in a larger discrepancy with actual samples (scan data) that have distortions or warping. On the other hand, in reverse engineering based on the contour shape of the cross-section, all surfaces are constructed from the deformed surface of the actual sample, leading to relatively smaller discrepancies with the scan data. To faithfully reproduce the scan data, reverse engineering based on the surface of the outer shape is more suitable, while if modifications are to be made to the created 3D data later, reverse engineering based on the contour shape of the cross-section is more appropriate. This time, we are basing it solely on scan data, but since the point cloud data obtained from a non-contact laser scanner inherently contains significant errors, it is necessary to use a high-precision contact measurement device to more accurately reproduce the shape of the actual sample.
