2018-06-19 10:43:23 -0500 | marked best answer | Error in loading whycon file I’m trying to run Whycon using ROS Kinetic with a USB camera on Ubuntu 16.04 LTS. I followed the whycon tutorial to calibrate the camera. After calibration, I ran in my home directory: sdorman@ikon:~$ ROS_NAMESPACE=usb_cam rosrun image_proc image_proc And in a new terminal: sdorman@ikon:~/catkin_ws$ rosrun image_view image_view image:=usb_cam/image_rect_color This worked with no issues. I then unpacked the calibration data from the tar.gz file using $tar -xvzf and then converted the ost.txt file to an ost.ini via And then ran: to convert to a yml file. I sourced catkin_ws and then moved up to the whycon directory to run Here I get the error “could not load file”. This error also occurs in any other directory than my catkin_ws/src folder. If I move back to ~/catkin_ws/src I get the following error. I’ve tried re-downloading Whycon and repeating the entire process but that did not work. I’m not sure where I went wrong, but any help would be appreciated. Here's the whycon_ros file: C:\fakepath\1st part of whycon.JPG C:\fakepath\2nd part of whcon.JPG C:\fakepath\3rd part of whycon.JPG WHYCON_TRANSFORMS.YML file |
2018-06-19 10:38:31 -0500 | marked best answer | Design a bounding box in Rviz using poses information I'm using ROS Kinetic on Ubuntu 16.04 LTS. I'm trying to draw a bounding box around four poses which are displayed as arrows in Rviz. I looked at using the Rviz Basic Shapes tutorial but I don't know how to adapt that code so that the box would remain around the poses if the position of the poses changed. From what I can tell, you have to manually set specific values for the vertices of the box in the Basic Shapes tutorial. I need the vertices to be determined from the pose positions. The poses are output as Is it possible to create this box? |
