The fabric deforms easily due to the physical constraints of its environment. The deformation of the fabric shape, including wrinkles, makes the precise pick-and-place of a piece of fabric difficult to automate its handling.

We consider the problem of building accurate three dimensional (3D)reconstructions of orchard rows. This problem arises in many applications including yield mapping and measuring traits (e.g. trunk diameters)for phenotyping. While 3D reconstructions of side views can be obtained using standard metho…
We present a novel method for extrinsically calibrating a camera and a 2-D Laser Rangefinder (LRF) whose beams are invisible from the camera image. We show that point-to-plane constraints from a single observation of a V-shaped calibration pattern composed of two non-coplanar triangles suffice to un…
Most Unmanned Aerial Vehicle (UAV) controllers require linear velocities as input. An effective method to obtain linear velocity is to place a downward facing camera and to estimate the velocity from the optical flow. However, this technique fails in outdoor environments when the ground is covered w…
