Seg fault when running the application

Open ashnarayan13 opened this issue 6 years ago • 1 comments

Hi,

I was testing the package for the occupancy grid generation. But I get a seg fault when I start the rosbag.

I just changed the topic names and the camera calibration parameters. The ORBSLAM visualization starts with the first frame and then there is a seg fault.

`Camera Parameters:

  • fx: 350.991
  • fy: 350.991
  • cx: 351.951
  • cy: 175.497
  • k1: -0.172415
  • k2: 0.0247573
  • p1: 0
  • p2: 0
  • fps: 30
  • color order: RGB (ignored if grayscale)

ORB Extractor Parameters:

  • Number of Features: 2400
  • Scale Levels: 8
  • Scale Factor: 1.2
  • Initial Fast Threshold: 15
  • Minimum Fast Threshold: 7

Depth Threshold (Close/Far Points): 4.80696 New map created with 102 points Segmentation fault (core dumped)`

Additionally, the rosrun tf static_transform_publisher 0 0 0 0 0 0 map ORB_SLAM/odom gives the following error [ERROR] [1521720489.728266546]: static_transform_publisher exited due to not having the right number of arguments Is this because of the frame_id mismatch?

Any leads would be helpful,

Thanks

Hi. I think the way you are calling the static transform publisher is wrong. It should take a frame rate also in the end. Try running rosrun tf static_transform_publisher 0 0 0 0 0 0 0 map ORB_SLAM/odom 10
