depth mapping using web cameras [closed]
i'm working on ROS electric. I have 2 iball web cameras separated with distance 12 cm . i used stereocamera-v4l2-ros-pkg for publishing stereo images. it is publishing on topic stereocamera/leftimage, right image etc. i did camera calibration with epi 2.5. Next i did stereo_image_proc for depth mapping. i'm getting only blank displays in all 3 windows.. can anyone figure out what mistake i'm doing here? what drivers are used normally for this stereo image publishing for disparity?
Thank You..
i used uvc_cam driver and i calibrated my web cam with epi 0.25. then i did image_proc for my monocular webcam. i have problem only in stereo disparity mapping. for stereo calibration, epi was 2.5. is that the main problem for not getting disparity map?
now i found stereocamera-v4l2-ros-pkg doesnot produce disparity. so suggest me a driver
hi, could u elaborate ur task as not many people now try to use 2 cams to make them work like a stereo. they either use kinect or a stereo cam to get the work done as 2 cams give erroneous outputs n its difficult to handle their disparity on a moving robot.
yes. i need to find depth(distance) in an image. i have done face detection in mono vision. next i will do the same in stereo and find distance the face is located from camera. this is my goal.
