Data Models For Product Modification using Reverse Engineering
Reverse engineering is the process of giving out a system, device or object to view the different parts of this object and try to understand how each of them work with the others to create one functional unit. This is an important process as it has enabled people to understand how tech works and how it can be used and maximized. Improvements can be done through the innovation of applied technology, making innovations much better.
Traditionally, reverse engineering services used analog and GPS scanning technology to gather spatial data of operating systems and objects. Today, most engineering companies use laser scanners for this process.
3D laser scanning has several advantages over the traditional scanning methods, particularly in terms of scanning time and the cost of scanning. Reverse engineering services use laser scanners for a variety of applications but in each case, the scanning results are used to produce models that allow the company to fabricate objects with relative ease. The models include the hybrid surface models, the parametric, and shrinkwrap surface models.
The Parametric Models
Parametric models convert ideal data from scanned data, and can ignore or incorporate manufacturing defects. This is to say that the parametric model parameters are presented in finite-dimensional parameter that distinguishes them from nonparametric models, semi-nonparametric models, and semi-parametric models. Parametric models are used whenever 2D drawings are required when a product's surface must be smooth, when the parts will be built on a scanned part, or when the scanning data will be conceptually modified.

The Hybrid Surface Models
Similar to the parametric models, hybrid surface models can convert realistic data from scanned data, and can ignore or include the manufacturing defects. Hybrid surface models are suitable for when the modification of an object requires re-trimming or must be a class-A surfaced. Hybrid surface models, just like their name suggest, are used in the modification of the surface of objects, and are therefore ideal when superficial modifications are made to an object. Hybrid surface models are also usable when 2D drawings are needed, when building on or around a scanned object or when the object's surface finish must be smooth.
Shrinkwrap Surface Model
Shrinkwrap surface models are used to capture in their as-built state, including production defects, making them ideal for designing parts to accommodate as-built models. Mainly, there are three types of shrink wrap models: surface subset models, used to compose a collection of external surfaces and datum figures; solid faceted models which are used to give an approximate representation of the original object; and subset surface models, which are used in approximating the visual presentation of the original object.
