Form Analysis of cone with FormFittingToolbox (Geodäsie/Vermessung)

SarhatAdam, Tuesday, 24.01.2012, 19:10 (vor 3964 Tagen)

I have a set of 3D data took by Laser Scanner on a cone with the following information
The apex of the cone data is (10.156930,-3.498146,-1.440301). The cone was produced in the following parameters
1-Radius of its circle base is 15cm
2-slant height= 30 cm i.e slant height=Diameter of its base
3-height of the cone from apex to the center of its circular base is calculated via Pythagoras theory is 25.981 cm
if you have any question please let me know.
I attached a copy of points here

Hi SarhatAdam,

"calculation aborted, iteration number has reached maximum (mx/dx =2.378) would you like to see the last solution?"

The Value is 2.378E+104 - note the E+104.

First, I check your date and make a simple sketch.

[image]

It is easy to see, that there is a leverage point far away from the point group. You have to eliminate outliers or, if you know the reason, revise the points. In your case, I belive it is a typing error. The sign of point 73 is interchanged:

72 10.1954 -3.4978 0.3293
73 -10.245 3.6582 0.1989
74 10.2488 -3.6741 0.1991

I changed it to:

73 10.245 -3.6582 0.1989

and got the following solution with the FormFittingToolbox:

Mx 10.135203018 0.000548132
My -3.469062048 0.000988097
Mz  0.292279887 0.000588639
Nx -0.784882919 0.001796108
Ny  0.619618011 0.002276894
Nz  0.005685347 0.002481430
α   2.610069091 0.002119551

The apex of the cone data is (10.156930,-3.498146,-1.440301).

Check your a priori information about the apex, because there is no point with a z-value nether 1m.


kind regards
Micha

Hello Micha

Sorry for being late on replying to your nice solution, yes it is true that point73 is outlier, how I couldnt notice it.

Thanks a lot for your effort I highly appreciate it.

Can I ask what Nx, Ny, Nz, α are refer to cause I know that Mx, My, & Mz is the centre of the cone.

Are there any formula for cone in 3D space or can I do my least square my solve. I need to understand the matrix how it was build in to least square solution.

Many thanks for you, I really appreciate your contribute and your answer...

Hi SarhatAdam,

first, please don't send an email to the forum-adress. You got this mail, because you enabled the notification-option.

Can I ask what Nx, Ny, Nz, α are refer to cause I know that Mx, My, & Mz is the centre of the cone.

The vector n = \begin{pmatrix}n_x & n_y & n_z \end{pmatrix}^T is the rotation-axis of the cone. This vector is also an unit-vector. The point m = \begin{pmatrix}m_x & m_y & m_z \end{pmatrix}^T lies on n. The angle \alpha describes the angle between the vector n and the curved surface area of the cone. Therefore, the formula describes a cone with infinite length.

Are there any formula for cone in 3D space

There are some other ones e.g. in Sung Joon Ahn: Least Squares Orthogonal Distance Fitting of Curves and Surfaces in Space.

I need to understand the matrix how it was build in to least square solution.

I used a so-called rigorous Gauss-Helmert model (general least-squares) e.g. Charles D. Ghilani, Paul R. Wolf: Adjustment Computations - Spatial Data Analysis.

kind regards
Micha

Hello Sarhat,

Thanks for your clarification

No problem. If it is helpfull to see the source-code, you get it on sf.net e.g. Cone.java. You can extract the formula from line 173:

\frac{(x_p-m)^T n}{||(x_p-m)||\;\cos(\alpha)} = 1

it seems that the subject is not that ease that I imagined I will do some literature...

It is simple enough, belive me. ;-) If you have questions, you can ask me here.

Hello Michael

This is me again, I think you helped me better than what I thought and I really feel that I bothered you by asking you too question but I thing it will be a last question that I ask. My question is can I get the Cone.Java working separately from the javagraticule3d or it is just a source code that I need to compile it in C++ and run it from their.

Hello Sarhat,

Do you mean a single adjustment-tool (cone only) without a GUI which can be start in bash-mode like:

application.jar myPointSourceFile.txt myReport.txt

I can compile a simple console-version, if you want.

or it is just a source code that I need to compile it in C++ and run it from their.

No, there are some dependent files. If you only translate the cone.java it will not run.

regards
Micha

Yes Please I really need to run a single adjustment-tool (cone only) without a GUI

and as I understand any bash command line should work likw Python or do I need only the

application.jar myPointSourceFile.txt myReport.txt.

I highly appreciate if you can compile console-version it it is not a time consuming for you

Hi,

please find here the command line version (cone only): ConeFFT.zip.

The application needs at least one argument - the point-file. Optional, you can define a (path to the) report file (default report.txt) and a damping parameter (default 0). I add two batch files (ConeFit.bat for Windows; ConeFit.sh for Linux) to show you the usecase.

Choose one of the follwing commands to start the adjustment.

java -jar -Xms200m -Xmx500m ConeFFT.jar points.txt
java -jar -Xms200m -Xmx500m ConeFFT.jar points.txt report.txt
java -jar -Xms200m -Xmx500m ConeFFT.jar points.txt report.txt 0
 

Hope it works. Let me know, if you have any problems! If it works and you are pleased with the adjustment results, please refer to Java Graticule 3D.

kind regards
Micha

Hello Michael

I am really not sure how to describe my thanks to you, you are really a generous person and gentleman. I hope from all my heart that you find a success in your entire life. I wish you all success. Yes, it is perfectly work in cygwin from Win7.

Hi Sarhat,

thank you for your reply.

Yes, it is perfectly work in cygwin from Win7.

You don't need cygwin to run this application. Do you have installed the java runtime enviroment on your win7 computer (and is this installation in your environment variable)?

You can test your installation online - Check to ensure that you have the recommended version of Java installed for your operating system.

If the test failed, please install the current version from http://java.com/ for win7. Check your installed version and open a command line window and tip:

java -version

What replies your computer?

[image]

If you get an answer like java is an unknown command, the java-command is unknown. You can add the bin-directory (e.g. c:\java\jre\bin\) to your environment variables or you work with the absolute path like:

c:\java\jre\bin\java -jar -Xms200m -Xmx500m ConeFFT.jar points.txt

Hope it works!

kind regards
Micha

Hello Maichael

Yes I have Java installed on my pc and I used that solution and it is perfectly working and I opened the report which I can see the parameters. The only question that I stuck on is how I can use those parameters for finding the apex (x, y, Z) of the cone.

Hallo,

he only question that I stuck on is how I can use those parameters for finding the apex (x, y, Z) of the cone.

I plot your points (blue) and add the vector m (red) from my solution to the plot. Do you dissatisfied with m?

Hello Micahael

Yes I can see it should be the best solution but finaly I think it depends on the dens of points distribution around the cone I also draw them in AutoCad and I can see the position clearly with small amount shifted toward dense points. But is suppose to be the best solution.

Hi,

Yes, but I don't have other information about the cone during the adjustment-process.

But is suppose to be the best solution.

... with your points. Of course, it is possible, that you get a better solution with a homogeneous point cloud but thats not the only influence on the estimated parameters.
