3d road reconstruction plays an essential role in road information extraction;however, the existing 3d point cloud registration methods cannot provide high accuracy and robustness for 3d road reconstruction. We propose a multi-direction registration framework for 3d road reconstruction using vehicle-borne LidAR and integrated navigation system (INS) data. The framework includes five modules. Module I acquires road point clouds with rough geographical locations. Module II presents a novel key point matching algorithm to reduce the displacement deviation along the travel direction. Module III constructs a dual-plane sliding window to extract curb and pavement point clouds. Module IV develops a plane-to-plane registration algorithm for rough pavement registration. Module V extracts the intersection line between the pavement and curb for curb registration. Experimental results demonstrate that our method can achieve state-of-the-art performance in reconstruction accuracy and technical robustness.

We have designed a 3d-printed microfluidic valve for implantable drug delivery in this work. The valve has a diameter of 6.5mm and a length of 13.5mm. To fabricate the micro valve, an alternative approach and process was developed to promote the usual injection molding process. This technique is a quick, cost-effective, and efficient way of manufacturing. In this valve, a silicone membrane that serves as the valve core, as well as the UV curable glue used for sealing, are all biocompatible materials. According to the experimental results for the control of fluid flow, the micro valve can adjust a flow rate of 30 mu L/min and can also control a modest flow rate.
