The default obstacle detection parameters may not be appropriate to segment obstacles like this. You can tune obstacles_detection nodelet to segment using a passthrought filter. As long as the ground is relatively even, that could work.

Set Grid/NormalsSegmentation to false, then adjust Grid/MaxGroundHeight to filter the ground (e.g., 10 cm). This assumes that the base frame of the robot is at ground level.
