Hi, i'm using ueye package for using 2 ueye camera for stereo processing.I did like this

rosrun ueye stereo

and verfied the frame rate by

rostopic hz for the left camera it is 30.015 and for the right camera it is 29.143. How to get the same frame rate for stereo processing without hardware synchronisation? Details: ros-indigo-ubuntu14.04

Thanks in advance,

Hi, I'm trying to view the 3D point cloud in rviz but it is displaying in reverse direction.I have checked the image, it is working normal. I'm using ros - indigo - ubuntu14.04 and RViz version 1.11.14 (indigo) To be more specific, I'm viewing the 3D point cloud (points2) from stereo camera and publishing the tf using the command below, rosrun tf static_publisher 0 0 0 0 0 0 left world 100.

fixed frame:world target frame: left (sensor frameid).

The problem is that 3D point cloud which is displaying is in reverse direction on contrast to the raw image.

any suggestions?

I have a rosbag file which publishes the stereo images (left_image and right_image) but there is no camera_info attached to it.I want use the stereo_image_process packagelink text to get the point clouds.This node needs the image as well as camera_info to process the disparity and point cloud. I have calibrated file in.yaml file format but i don't know how to publish the information in it in a camera info topic for left and right images (camera)

Also,what is the best way to do the above issue with less computation?

Many thanks in advance
