1.1.6 (2010-06-01)

camera_calibration:

• Fixed to work with arbitrary size images, not only 640x480.
• Regression tests for multiple image sizes.
• Fixed cosmetic problem in update of small images.

1.1.5 (2010-05-23)

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 (<<Ticket(ros-pkg 4035)>>).

1.1.4 (2010-04-27)

camera_calibration:

• Updated cameracheck to work with stricter topic name checking (#4036).

1.1.3 (2010-04-26)

This release includes bug-fixes from 1.0.1 and 1.0.2. Other changes listed below.

camera_calibration:

• camera_hammer utility for testing a set_camera_info service call.

image_view:

• Workaround for exiting when the user closes the window on Linux systems (#3026).
• Source files and executables now go in src/ and bin/ (#3978).

1.1.2 (2010-04-12)

stereo_image_proc:

• Force min_disparity to be zero when using WG block matcher, which doesn't support non-zero values.
• Explicitly zero out border pixels that tend to have junk when using OpenCV block matcher. (Probably fixed in more recent revisions of OpenCV)
• Made OpenCV the default block matcher, preparing to remove WG reference implementation.

image_proc:

• Specific error message on receiving image with ambiguous 8UC3 encoding.

camera_calibration:

• Can initialize calibrators from CameraInfo messages (#3891).

1.1.1 (2010-03-12)

• Changed default stereo_image_proc settings to give good stereo results on PR2 data.

1.1 (2010-03-10)

camera_calibration:

• calibration no longer makes buggy assumptions about corner spacing always being .108m
• Added a simple calibration script (camera_calibrate_from_disk.py) that loads a set of images from disk and performs monocular calibration returning the camera intrinsics.
• Set projection matrix P correctly in monocular calibration.

image_proc:

• Warn if color topic requested but raw image data is grayscale.

stereo_image_proc:

• Allow using either the OpenCV block matcher or the Willow Garage reference implementation. Should give roughly the same results with vision_opencv 1.1 or greater.

• Added points2 topic with the new sensor_msgs/PointCloud2 format.

• Upped texture_threshold maximum to 10000; high values needed for simulated stereo images.
