Hi~ Please check whether your LSDslam node subscribe correct image topic(image after calibrate). It might be similar to "/ardrone/front/image_rect". By the way, you can also use rqt_image_viewer to see the image topic : )
Yes it's better with image_rect!
You know how change the voxel's size with octomap? Because i have to much voxels and my computer has blow up. I try to change the 'resolution' value in /ar_drone_moveit/launch/octomap.launch but nothing change :(
Edit: I find the good 'Resolution' parameter in ar_drone_move_it/launch/ar_drone_move_it_sensor_manager.launch.xml
Thx!
Hello, I try many times to calibrate my drone with 'camera_calibration' node. But when I commit the result and use lsd_slam I have a bad result like this:
If you have a good result with your drone I just want your tips for a good calibration.
It's could be the resolution ? Because my calibration view is like that :
My calibration file :
