depthimage_to_laserscan outputs laserscan upside down
Hi everyone, Im having trouble with depthimagetolaserscan, its essentially upside down, if i try rotate the TF by 180 degrees the map is offset from the laserscan? is there anyway to flip the depthimagetolaserscan?

Did you try to flip your depth image?

How is that done?

Use OpenCV function
flip: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html?highlight=flip#cv2.flipSee this post for details http://stackoverflow.com/questions/16265673/rotate-image-by-90-180-or-270-degrees

I know there is a way with OpenCV but this would consume much more processing power flipping each depth image?

This will not affect performance at all if you are working on a desktop or on a laptop.

The other way to do image processing is by means of
image_transportbut I did not find a method for image flipping. Or you can tryimage_rotatepackage http://wiki.ros.org/image_rotate but it does the same opencv operations.Asked by VitaliyProoks on 2015-09-14 00:25:22 UTC
The depth camera is on a Raspberry Pi.I will try that, thanks for the help.
