Hi. I'm working with RVIZ and I want to put an image (map) in the background instead of the default grid... How can I make this?

Thanks.

2017-01-03 10:12:17 -0500 asked a question Distance between a robot and a line

I want to calculate the distance between the current position of my robot and the lines that are constructed with my function cv::line. My line is resultant of a hough transform with the function HoughLinesP. How can I calculate the distance? Or instead,how can I get the position of the robot and the lines?

Thanks! Any help will be appreciated.
