Hi there. i managed to get rgbdslam running with both gicp_code and gicp_bin. the problem is, when using gicp_code, the program runs for some time (about 3 or 4 seconds) and then it shuts down. when i use gicp_bin, after i hit the space bar, i get Non-zero return value from ./gicp/test_gicp... Identity transformation is returned instead of GICP result... sh: ./gicp/test_gicp: not found. could anybody figure out why? i'm using the rgbdslam checked from openslam.org. My CPU is i5, 4G memory. Ubuntu 10.04

thanks in advance.

Hi, we hadn't touched the GICP code for a while, since it didn't improve our results. Since we didn't test it anymore changes elsewhere broke the GICP functionality. I fixed that and will properly release a new version as soon as my work schedule permits. Try updating your svn in a few days.

However, in my experiments with GICP, SIFTGPU and SURF the results with Features+GICP are still slightly worse than Features only. Depends on the scenario of course.
