2016-01-12 23:08:36 -0500 | asked a question | is the swissranger no longer supported by ros in the indigo release None of the launch files and the related swissranger cod is no longer compiled in cob.

2015-11-08 07:13:46 -0500 | answered a question | Will this Project be possible? / ROS Time Syncronisation I have had to combine 5 different computers where 1 machine is the ROS_MASTER and the other are not. I can get sub microsecond accuracy but this requires a continual time update from the master server. I use and NTP server on the machine running ROS_MASTER. The remaining machine i run a simple cron job updating the time. |
2015-11-08 07:08:40 -0500 | answered a question | convert from sensor_msgs::Image bgr8 to a png file on disk Good or bad the code compiles and links. I will need to check the routine at work: This involved linking in boost and cv_bridge also painful. void convert_image_BGR82PNG(const sensor_msgs::Image msg) { } |
2015-11-08 07:07:44 -0500 | asked a question | convert from sensor_msgs::Image bgr8 to a png file on disk This is the subroutine I need. What is holding me back from converting the rgb image you send me is converting to a png file. This is done by using cv_bridge to convert from ros to the cv space. The problem is cv is expecting a const sensor_msgs::imageConstPtr msg I only have a const sensor_msgs::image. We need to use “boost” some way to make a new member. Do you remember the syntax? void convert_image_BGR82PNG(const sensor_msgs::Image msg) { } |
