2016-10-25 17:20:47 -0500 | asked a question | how to transform image from one coordinate frame to another coordinate frame using c++ I have two images from two different cameras, for which I have done both intrinsic and extrinsic calibration. I have done transforming point clouds(3D) from both the cameras to base_link frame and added together(point cloud registration). I wanted to do the same for 2D images. That is, I want to transform both the images and stitch it together so that I get one large image as if taken from one single camera. Is my approach correct. If so How would I do it. Thanks in advance. |

I want to get the frame_id from msg, so that I can set multiple cameras with respect to world frame dynamically. I am using Asus Xtion pro live, so I launch ar_track_alvar with pr2_indiv_no_kinect.launch. This is what I have done, Launch file, My ros Node, Output of rosrun camera_tf_pose camera_tf_pose Output of rostopic echo /ar_pose_marker when I uncomment the following lines, (more) |
