New visual positioning and adjustment techniques for cylinder target are presented based on three-microscope vision system, which is used for visually guiding the manipulation of microparts with an eye-to-hand configuration. An image-based visual control (IBVC) with image Jacobian matrix and a position-based visual control (PBVC) algorithm for the three-microscope vision system are investigated. In...
In this paper, a simple and efficient 3D surface reconstruction algorithm which can be implemented on mid or low-end computers is proposed. In this algorithm, the 3D images are obtained by a depth motion sensing device named Kinect. Data from region of interests are obtained by segmenting images whose k-neighbor relationship is established with a k-dimensional tree (KD-tree). After patching the point...
Towards the intelligent wheelchair's parking into and docking with a U-shape bed to expand as a complete size-wide bed, a U-shape contour detection and wheelchair localization method is proposed in this paper. Lines contained in the back-view image of the wheelchair are projected into the bed's superface plane and furthermore separated into several groups based on conditions of parallelism and perpendicularity...
