Open LiaoJunchan opened 5 years ago

LiaoJunchan commented 5 years ago

Successfully run the launch file (loam_velodyne.launch), but once I play the bag of VLP16, error below occurs. What does this error means and how to solve it? [multiScanRegistration-2] process has died [pid 24636, exit code -11, cmd /home/fergus/loam_velodyne/devel/lib/loam_velodyne/multiScanRegistration /multi_scan_points:=/velodyne_points name:=multiScanRegistration log:=/home/fergus/.ros/log/6c595248-4ae7-11e9-a43a-b46d83213513/multiScanRegistration-2.log]. log file: /home/fergus/.ros/log/6c595248-4ae7-11e9-a43a-b46d83213513/multiScanRegistration-2*.log

作者的repro的readme里面已经有介绍了,必须源码编译的pcl库才行

I am experiencing the same issue, tried several .bag files including nsh_indoor_outdoor.bag. In BasicScanRegistration::extractFeatures() method of BasicScanRegistration.cpp there is a for loop for (size_t i = beginIdx; i < nScans; i++) {...} which executes only once (i=0), finishes the whole block and interrupts the exectuion of the multiScanRegistration node after completing loop exactly once. I could not notice any errors in code, the for-loop simply stops before entering 2nd loop.

The problem turned out to be related to the issue #71. pcl lib incompatbility. Although they suggest removing pcl lib and building it from source, I followed advice to remove line add_definitions( -march=native ) from loam_velodyne/CMakeLists.txt as suggested in issue #71 thread Just comment the line, compile and the node will not break with execution.
