Form Analysis of cone with FormFittingToolbox (Antwort)

Hi,

I think it depends on the dens of points distribution

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.

kind regards
Micha

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.

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?

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.

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?

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
