In order to make an improvement of accuracy, completeness and robustness of the image based 3D reconstruction algorithm, we present a stereo matching approach under the condition of multi-resolution combined with multi-constraints to compute the 3D model of an object in this paper. In the first step, we build the image pyramid and stereo matching happens from the top level to the lowest level. In each level, we execute the following procedures: NCC matching, multi-constraints checking, re-matching and weighted median filter, disparity refinement. At last, we acquire an accurate and smooth disparity map in the bottom level. Combine with the calibration parameters, we can compute the 3D point cloud and use the Possion reconstruction method to generate the mesh model. The contributions of this paper are the proposal of choosing the pixel in the eight-neighborhood which has the highest match cost to guide the matching of center pixel during re-match, and design an anisotropic smoothing kernel to smooth the depth map and keep the detail at the same time in the disparity refinement. Experimental results show that the algorithm has the advantages of high precision, strong robustness and good model integrity. © 2015 IEEE.

IEEE International Conference on Robotics and Biomimetics, IEEE-ROBIO 2015

A real time visual hull parallel computation method is proposed based on GPU. Firstly, an effective Octree data structure is built on GPU, which establishes the correspondence between voxels and the thread ID of CUDA. Secondly, for large-scale parallel data in the projection test of visual hull calculation, the convex hull of the projected vertices is accelerated to use the GPU programmable features. Finally, the redundant edge computation in marching cubes algorithm is reduced by building the edge lookup table. Then, parallel streaming data reduction based on prefix-sum excludes empty voxels from the lookup table, which can improve the computation effectively. Experimental results show that, for large-scale data, accurate visual hull can be efficiently reconstructed by the proposed algorithm on a common PC and GPU platform. © 2015 IEEE.

Stable and fast switching between displacement and pressure will directly affect precision and velocity of automated equipment. Switching control between displacement and pressure, which is based on the velocity damping, is proposed for motion switching of automated equipment. At first, the control models were established by analyzing displacement control and pressure control. To solve the shortage of direct switching between displacement and pressure, switching control based on the velocity damping is presented. The effectiveness of this method is verified by using piezoelectric sensor in experiment. Compared to direct switching control, the proposed switching control becomes more accurate and faster. The measurement data shows that the maximal impact force of control system is 0.4N and the amplitude of forces of fluctuations are within the range of ±0.03N. © 2013 IEEE.

Connection frame has been a key module in a macro-micro platform. The error of connection frame deformation must be taken into account for nano-positioning motion in working process. While working, the nano-positioning motion is affected by the two major deformation error sources: magnetic force and thermal structural coupling effects. These error models were built by response surface method. Each experiment result can be obtained by calculation of finite element method. Their input variables of orthogonal experiment design were imported to the commercial software ANSYS to calculate and obtain output. The response surface model was built by the input and output data. Based on these models, change trends of deformation errors with design parameters can be revealed. And an optimal model of total deformations errors would be built. Finally, the minimum error of connection frame deformation considering magnetic force and thermal structural coupling effect was calculated by genetic algorithm. The optimal solutions were obtained when the total error iterate to 15 times as follows, D=32mm, L1=80mm, R=64mm. The improvement of deformation error considering magnetic force, thermal-structural coupling force and high acceleration is 86.48%, 0.26%, 26.85% These results can provide a more accurate prediction of error analysis in more widely used cases and also offer a theoretical support for improving nano-positioning accuracy of macro-micro platform. © 2014 IEEE.

To achieve higher accuracy of Micro Wire Electrical Discharge Machining (MWEDM) and solve the problem that the wire electrode is easy to broken, this paper studies the dual-motor optimal control of wire electrode constant tension system. Aiming to eliminate the tension measurement noise caused by the vibration of wire electrode etc., Kalman filtering algorithm is proposed to fuse tension and speed sensor. The accurate dual input dual output mathematical model of wire drawing and tension wheel is established, the minimum performance index which is the sum of the wire speed and tension squared error is achieved by optimal control, which make the accuracy of the tension improved greatly. The disturbance observer is employed for the actual processing environment to cancel the modeling error and interference. The simulation results show that the expected control performances are achieved.

In this paper, a novel navigation based on vision for wireless capsule endoscopies is proposed. The algorithm based on dark regions was improved by setting the Region of Interest (ROI) to limit the search coverage around the last navigation point, introducing the morphology method to eliminate diverticula and vesicae and raising the concept of position weight to reckon navigation points in the case of lacking for valid dark regions. Besides that, we proposed the method based on template matching, which is common in industrial detection, to navigate when the method mentioned above fails. Finally, the two methods were fused and it's proved beneficial to both the success rate and the computation speed by simulation and experiments.

In the off-line programming system, robot collision detection is one of the key technology and that was an important factor to improve virtual realistic system. In order to attain robot trajectory in the virtual environment, accurate and fast collision detection is requested. Aiming at this case, this paper adopts an accurate and fast collision detection algorithm based on space subdivision method. Through the using of hierarchical bounding box method and space decomposition method comprehensively, it can reduce the logarithm of triangles in the collision detection algorithm and increase the efficiency. One measure to be taken is to update moving objects' bounding boxes at any time, but don't change the stationary objects' bounding boxes which are built initially. Moreover, the distance threshold is also introduced, which make the collision detection more accurate. The simulation result shows that the detection method can meet the requirements of accuracy in complex virtual environment.

The rising use of wireless endoscopy capsules for the medical examination of the digestive tube has brought about an innovative step of medical experience. However, proceeding only by means of gravity and visceral peristalsis greatly restricts its clinical application, since their location, posture, and velocity cannot be controlled. The technology described in this paper uses an external magnetic field which is generated by two cuboidal extern permanent magnets (EPM) to drive the endoscopy capsule with one cuboidal permanent magnet (IPM) inside. EPM1 and EPM2 are fixed on the end-effector of two robots respectively. By changing the relative postures of robots, the interaction force and torque between IPM and EPMs change so that the endoscopy capsule can be controlled for full degree of freedom. In this paper, the interaction magnetic force components and torque components are analytically calculated based on Ampere molecular current hypothesis, Dipole theory and BiotSavart's law. The exact 3D analytical expressions are obtained and used for calculating the magnetic forces and torques, shape optimization and velocity control directly rather than ordinary numerical methods.
