It does seem like something might be up with the kinetic disparity view. When I "rostopic echo /stereo/disparity" I see the data flowing but is seems like something wrong with the valid_window data height and width numbers (see below):
rostopic echo /stereo/disparity
...... 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191, 0, 0, 128, 191] f: 739.351379395 T: 0.323849737644 valid_window: x_offset: 70 y_offset: 7 height: 4294967281 width: 4294967218 do_rectify: False min_disparity: 0.0 max_disparity: 63.0 delta_d: 0.0625
Is there a setting earlier in the chain that would screw up these numbers?
