7 years ago Ok, the point was that I had calibrated my cameras for stereovision, and for getting this object position I was using just one camera, so I should have calibrated each camera by itself. Now I have the position in meters, as I was looking forward.
Hello there, First of all, I want to thanks your effort by getting this powerful tool for robotics project. I am having a minor issue, that is, I want to control the head motion of my robot by the information procedding of the visp_tracker node, with a certain .launch which I have in order to get images from my robot cams. The point is, how could I convert from the values given by /object_position topic to real world values? I am not sure if I missed something, but I have been reading several pages the last few days, and I haven't found the answer to this main issue for me. Thanks for your attention. Best regards.
