1.4.0 (2011-02-10)

This summarizes important new features and changes since C Turtle (1.2.x series). For a complete list of changes including bug fixes, see the 1.3.x changelists.

The biggest new features are nodelet versions of image_proc, stereo_image_proc and image_view, and support for unsynchronized stereo cameras.

• image_proc

  • Refactored into nodelets for debayering and rectification.

• stereo_image_proc

  • Refactored into nodelets for stereo processing and converting disparity images to point clouds.
  • Support for unsynchronized stereo cameras.

  • In PointCloud2, now correctly set is_dense to False.

• image_view

  • Refactored into nodelets for displaying images and color-mapped disparity images.

  • New utility disparity_view for viewing disparity images only.

  • stereo_view support for unsynchronized stereo.

  • Now right click instead of left click to save images.

• camera_calibration

  • Approximate synchronization option for unsynchronized stereo. <<Ticket(ros-pkg 4691)>>

  • Camera calibration system data structures can now handle multiple size chessboards. <<Ticket(ros-pkg 3681)>>

  • Calibration now requires skew points for both mono and stereo calibration. <<Ticket(ros-pkg 4086)>>

• stereo_msgs moved to common_msgs.
