| 2016-03-29 11:26:43 -0500 | asked a question | focal length in pixel from fx and fy Hi, how can I get focal length in pixels from fx and fy? I need to get disparity using z = b*f / d, where z is the depth (in meters), b is the horizontal baseline between the cameras (in meters), f is the (common) focal length of the cameras (in pixels), and d is the disparity (in pixels). At zero disparity, the rays from each camera are parallel, and the depth is infinite. Larger values for the disparity mean shorter distances. I am using kinect with the focal length: fx_rgb = 5.1885790117450188e+02 * ratio; fy_rgb = 5.1946961112127485e+02 * ratio; Kinect is not a stereo sensor, therefore I dont have a "baseline". Please help Ayesha |
