I know that there are lots of question on his topic but after going through most of them i was not able to find solution for my problem

  • I am using stereo_image_proc for getting point cloud from stereo cam driver as i have provided below, i successfully gets both left and right camera output but i cant see pointcloud2 in rviz

  • I tried echoing the camera/point2 topic but the result seems weird[or is it ok ,I am new to these stuffs?]image description image description

  • is my output ok?if yes then what might be the reason i dont get pointcloud in rviz(I have tried rotating the window)

Edit: sorry after i again tried rotating i got the cloud but it seems weird rviz_result

The output is probably reasonable, as that is the array of uint8's that make up the images/point clouds. You can add the --noarr option to rostopic echo to get a more reasonable output.
