Question

calibration problem

Closed this issue 2 years ago · 4 comments

Hi,

I have two cameras BlackFly S. I calibrated them and I put the file into the default path. When I run two cameras the files of calibration are read by ROS. In fact, when I write in a new terminal:

ros2 topic echo /cam_0/camera_info

I can see the values. But the images of the camera are published without considering these values. Is there a way to do this or do I have to do it myself?

Sorry, but what do you mean with "not considering the value". All you can expect is the driver to publish camera info and image.

it seems to me that it doesn't work. there can be any value in the file but the image is always the same.

The driver will not rectify or modify the image in any form. Downstream software can use the camera info to modify the image as needed.
