The question about vins-supported #35
Comments
Grayscale image should not be a problem. As the error tells you, there is no fused point cloud. Is the synchonizing correct? |

I run vins-mono (not vins-fusion) with mynteye camera, and set estimate_extrinsic to 2 to calibrate the camera and imu. When I run roslaunch surfel_fusion fuse_depthnet.launch, the information is displayed as follows.
process[surfel_fusion-1]: started with pid [13628] Have the following settings: camera matrix: 358.474 0 388.407 0 359.527 254.769 0 0 1 fuse the distence between 0.500000 m and 3.000000 m. loop_path_input size: =30 poses_database size: =0 loop_path_input size: =31 poses_database size: =0 loop_path_input size: =32 poses_database size: =2 loop_path_input size: =33 poses_database size: =3 loop_path_input size: =34 poses_database size: =4
But when I run rostopic pub / surfel_cmd std_msgs/Int16 "data: 2" is used to end the map creation, the error shown below will appear.
