Hi all, image_pipeline 1.1.5 has been released. This is an unstable development release. image_pipeline is now feature frozen for C-turtle. Changelist : New package image_rotate , for visualizing camera streams in an orientation that is more intuitive to the user than the hardware-constrained orientation of the physical camera. This is particularly helpful, for example, to show images from the PR2's forearm cameras with a consistent up direction, despite the fact that the forearms need to rotate in arbitrary ways during manipulation. stereo_image_proc: - Removed WG block matcher option. OpenCV's implementation is always used. camera_calibration: - Mono calibration now reports linear error of the rectified checkerboard corners (#4035 ). -Patrick
