Vision 01-30-2012¶

Progress Installing Kinect¶

• Openni installed, but other build problems
• Panda sometimes mounts as Read Only FS
  • Try using a real power supply? Seemed to work better than USB.

Progress with vision algorithms¶

• Dan has an HSV processor/segment
  • Eliminates color changes due to lighting, gives hue and saturation

  • Look up ros::tf
  • Check for accuracy of roll and pitch
  • Write this function
