This is my final project of master's degree, that is, Automatic Industrial Measurement System Based on Registration.

The workflow of this system is shown as follows.

• Labeling/Marking a set of points representing the shape to be detected (10.2020)
• Coarse registration (11.2020)
• Fine registration (11.2020)
• Searching the points to be measured in the specified point cloud (11.2020)
• Combining all components (12.2020)

For now, all steps are tested and ran on Windows 10 with visual studio 2017.

Download from here.

Each step should have its dependencies libraries, also might require the whole libs as follows.

Here are four steps:

1. Marking/Labeling

   

   The red zone consists of red points marked by operators. Meanwhile, these zone is marked as points, line, or plane. This process will not participate in the real-time inspection.

2. Registration

   

   From un-registration to registration.

3. Searching marked points

   

   Searching marked points in scanned point cloud with registration result.

4. Measurement

   The inspection including defect detection and geometric measurement, follows a specific relationship describing the marking items as below:

   	Point	Line	Plane
   Point	1|2	1|2	1|2
   Line		2|3	2|3
   Plane			2|3

   '1' indicates the geometric relationship, '2' means the scatter relationship, and '3' means the angle should be calculated between two items based on the normal vector.

   Through Plane-to-Plane and Point-to-Plane, the measurement reuslt(mm) is shown as below:

   	Geometric	Scatter	Angle
   Plane-to-Plane	-	26.987	8.656
   Point-to-Plane	1.517	1.70	-

   We do not need all values in table above.
