Hello, I am using kinect sensor for the mapping and navigation in my project, As Kinect also have a RGB camera. I wanted to fetch the RGB image from the kinect, then do some processing and get the text data in the image using this data I want to re localise my robot.
Is this possible in ros.?
Many Thanks in advance.
Sure! just subscribe to the RGB image topic. Assuming you started the openni with
roslaunch openni_launch openni.launch
Just subscribe to /camera/rgb/image_raw topic. The sensor_msgs/Image messages you get can be easily converted to OpenCV with cv_bridge package.
Dear @sumanth, if this answer is satisfactory for you, please, mark it as correct. Also, it would be more appropriate to ask about the package for text extraction from images as a new question, as it could be helpful for other people. Thank you for helping us keep the forum organised.
