Subject: Measuring Landmarks from Point Clouds
To: morphmet@morphometrics.org
Just a little shameless self-promotion... I recently needed to digitise some
landmarks from a large series of point clouds and couldn't find any software
that made this process particularly easy so I wrote some. If you have similar
requirements then you might find the software useful. It is called
CloudDigitiser, it is open source and runs on Mac, Windows and Linux. You can
download it from my website at:
http://www.animalsimulation.org
The program uses the letter and number keys to assign points so you can
digitise up to 36 points per cloud very quickly indeed. It works on whole
folders full of point clouds and lets you step back and forth between the 3D
files with the cursor keys. It has various tools that let you align the point
clouds with arbitrary axes and will allow you to calibrate the clouds if they
are uncalibrated (e.g. from photogrammetry). However it cannot handle huge
point clouds very efficiently although it works fine in the 1 million to 10
million points range. It will probably work on bigger data sets but it will get
slower. It reads the commonest PLY formats only but they are widely available
and easy to convert to. The measurement data is stored in a human readable XML
format (which can easily be read by R and Matlab). The landmarks measured are
the mean of the points contained in a user specified sphere.
Let me know if you find it useful and if there are any features that you would
like. Some might be very easy to add,.
Cheers
Bill
