3D laser scanner

Hi there

I am Jolanta and from lativia and I am new to Matlab. I am using Laser sensor with NI PCle 6321 to acquire 3D images of a scanned object. I want to know whether it is possible to do the same using Matlab instead of LabView. I am using Lego Mindstorms made Robotic arm to move my Laser beam which gives me x,y,z points now I want to know How do I achieve this using Matlab. Your suggestions are really appreciated.

regards

Jolanta

Could you perhaps provide a small set of sample data and the expected results/image of expected results?

If you can watch this video. The application should be similar to this

Hi Jolanta,

You can now program & control the LEGO MINDSTORMS NXT directly from Simulink. One suggestion is to model the robot arm controller in Simulink and then load & run it on the NXT Brick. In MATLAB, you can use the Data Acquisition Toolbox to acquire the laser sensor data. Data Acquisition Toolbox provides support for the PCIe-6321. More details can be found here:

Simulink Support for Target Hardware, including LEGO MINDSTORMS NXT:

I hope this is helpful.

Interesting.

The question that then immediately came to my mind was whether the Simulink target was supported for both 32 bit and 64 bit MATLAB, so that the user would have a choice of legacy interface (32 bit only) or session-based interface (64 bit only) to communicate with the PCIe-6321.

It appears to me that the answer is Yes, that both 32 and 64 bit are supported at this time; I deduce this from seeing specific 32 and 64 bit support mentioned on the Mindstorms page, http://www.mathworks.com/academia/lego-mindstorms-nxt-software/legomindstorms-simulink.html

I'm pretty sure session-based DAQ only works for NI at this point.

[Walter Roberson]

Right, Sean, but the 6321 _is_ a NI device.

[Sean de Wolski]

And I can't find anything indicating support for any non-NI products.

[Walter Roberson]

http://www.mathworks.com/help/toolbox/daq/bsvjl59-1.html

has a chart that shows that session-based interface is supported only for NI devices, and that for other manufacturers, only the legacy interface is supported and only 32 bit MATLAB.

Hi Guys Thanks for the reply.

But I cant find target installer on my Simulink. I am using Matlab 2011b, buyt in my tools of new models in simulink there is no option of run target installer.

Hi all,

Can you help me for my final year project about 3D scanner image using laser. So, I hope could everybody help me by providing the complete matlab coding for this project.

Thanks and have a nice day
