Geometric Reverse Engineering

Reverse engineering is a reciproc process where you start from the end! as example when you have a shopfloor process already done but without any treacability ! so you start by using suitable modelling language to modelize it . when you have a product and you want to have it geometrical model , this is  Geometric reverse engineering.

Geometric reverse engineering

One defintion of geometric reverse engineering is the process of obtaining a geometric model from a real manufactured part acquired by 3D measuring and digitizing techniques.

There are main phases:

  • Point Acquisition
  • Point Processing (filtering, Point Processing meshing, topology construction, registration, , meshing, topology construction, registration, etc)
  • Model development

Geometric reverse engineering techniques

There are so many techniques and machine used in  Geometric reverse engineering, such as:

  • Laser point scanning (1D)
  • Laser range scanning ( 2D)
  • Constructed lighting (3D
  • photometric stereo, etc
Capture
reverse engineering machines

There are also many categories of geometrical reverse engineering Thechniques , which could be :

  • Active optical, under this category there are five types: Optical triangulation, Optical interferometry, confocal micriscipy, deflectometry and Time of flight.
    • Systems which are using the technique of Optical triangulation are
      • Laser point scanning (1D)
      • Laser range scanning ( 2D)
      • Constructed lighting (3D)
    • Systems which are using the technique of Optical interferometry,
      • Moiré interferometry
      • White light interferometry
    • Systems which are using the technique of Confocal micriscipy are:
      • Chromatic confocal imaging
      • Mono Confocal Imaging
  • Passive optical, under this category there are four systems: Stereoscopic, Shape from shading, Photometric stereo and profile vision
  • Computer tomography
  • Acoustic
  • Magnetic
  • Touch trigging , under this category  there are three systems: Kinematic resistance, stain gauge and piezo shock
  • Touch scanning, under this category there are two systems : passive and active.
Capture
Mono Confocal Imaging
