Download DLR CalDe and DLR CalLab

Feel free to download the compiled IDL programs as well as some sample files. We kindly draw your attention to the copyright clauses at the end of the document.

1. About

The camera calibration suite consists of two separated programs, that is DLR CalDe (camera Calibration Detection tool) and DLR CalLab (camera Calibration Lab). CalDe aims at the measurement of the salient points of a specific calibration object. The measured points are read and processed by DLR CalLab which finally provides the intrinsic camera parameters as well as the extrinsic parameters for stereo cameras and/or eye-in-hand cameras.

2. Installation

First, download and unpack DLR CalDe ( calde-v0.99.3-IDL7.0.zip or calde-v.0.99.3-IDL7.0.tar.gz ) and DLR CalLab ( callab-v1.01-IDL8.0.zip or callab-v1.01-IDL8.0.tar.gz ) into a directory of your choice, hereafter named ${CALLAB}. Second, download and install the free IDL virtual machine from http://www.exelisvis.com/ProductsServices/IDL/IDLModules/IDLVirtualMachine.aspx into a directory, hereafter named ${IDL}. DLR CalDe and DLR CalLab work at least under Sun Solaris, Linux (32-bit), Mac OS X, and Microsoft Windows (NT, 32-bit).

Sample files are also available ( sample.zip or sample.tar.gz ).

In addition, Wolfgang offers the following Mathematica notebook: CallabUtil.zip . It contains I/O, projection, distortion, and undistortion functions. Further examples in the Brief Tutorials section.

3. Execution

Run CalDe via
${IDL}/bin/idlvm -vm=${CALLAB}/calde/calde.sav

Run CalLab via
${IDL}/bin/idlvm -vm=${CALLAB}/callab/callab.sav

NOTE: As of 2010 (IDL version 8.0), EXELIS VIS seems to have broken this tradition and no new virtual machine is available anymore. The (registered) user can however download and install the full IDL package. ${IDL}/bin/idl will now take ${IDL}/bin/idlvm's place.

4. Newsletter

Our newsletter informs on new versions of DLR CalLab and DLR CalDe. To receive mail please subscribe by sending an e-mail with the subject "subscribe" to rm-callab AT dlr.de from the desired e-mail delivery address.
