An inversion model of stereo-vision that connects the object space and the image space is derived to obtain three-dimensional coordinates of object point in the object space from two-dimensional image coordinates of a pair of image points in the image space. An algorithm based on multi similarity measurements and multi-matching areas is proposed for stereo matching of color images, which considers the impacts of similarity measurements and matching areas fully. In this algorithm, the samples of matching output are acquired by the statistics of multi similarity measurements and multi-matching areas. On the other hand, the false matching results and the wrong matching results are partially filtered by performing the mean-square error statistics of matching output samples. Furthermore, a sub-pixel matching accuracy is expected by calculating the average values of two new samples derived from the mean-square error statistics. In the software platform based on VC++ and OpenGL, computer-aided design is designed for filter of abnormal data.","PeriodicalId":250844,"journal":{"name":"2013 IEEE International Conference on Information and Automation (ICIA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120996174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to its configuration characteristic, the 6DOF of the inverse kinematics problem was decomposed into two 3DOF sub-problems: the position inverse kinematics and the attitude inverse kinematics. Then the two sub-problems were respectively solved analytically, and four sets of solutions of the joint variables were obtained. By adopting the configuration flag, the appropriate solution corresponding to the flag can be determined. Furthermore, the circular trajectory in Cartesian space of the grinding robot was planned to perform the grinding tasks. By taking advantage of the analytical inverse kinematics, the planned Cartesian trajectory is transformed into joint-space. Finally, a simulation system was developed by using Matlab/Simulink software. Based on the system, the analytical inverse kinematics solution and trajectory planning method was studied by numerical simulation. The simulation results showed the effectiveness of the proposed method.","PeriodicalId":250844,"journal":{"name":"2013 IEEE International Conference on Information and Automation (ICIA)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121374984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contrary to the experience based trail and error convention to select a light system, a optimization model for LED illumination system design is proposed based on the surface reflection characteristics, e.g. the roughness, the index of surface reflectivity, direction, etc, to maximize the contrast between the features of interest and the background. The optimization model applies to a wide range of materials. And it can be used to get the optimal parameters which make the contrast between target and background be biggest, such as incidence angle, wavelength and intensity of light. Through experiments and simulations, our proposed scheme can achieve high quality images with biggest contrast, which would be an efficient methodology for optimal LED light system design in machine vision to simplify the algorithm.","PeriodicalId":250844,"journal":{"name":"2013 IEEE International Conference on Information and Automation (ICIA)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126155787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The constraint of signal sparsity can be implemented by l0 norm minimization, which is an NP-hard problem that requires exhaustively listing all possibilities of the original signal and is difficult to achieve by the traditional algorithm. This paper proposes a signal reconstruction algorithm based on intelligent optimization algorithm which combines genetic algorithm (GA) and Bacteria Foraging Optimization (BFO) algorithm. This method can find the global optimal solution by genetic and evolutionary operation to the group, which can solve l0 norm minimization directly. It has been proved through numerical simulations that the theoretical optimization performance can be achieved and the result is superior to that of OMP algorithm.","PeriodicalId":250844,"journal":{"name":"2013 IEEE International Conference on Information and Automation (ICIA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126946632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The double rho iteration model used by the space-based initial orbit determination is briefly introduced firstly. Because of problems of iteration divergences and self-solutions in the space-based initial orbit determination, the genetic algorithm of SGA and MPGA are then adopted to solve the problems. According to the research results, the space-based initial orbit determination generally got more satisfied solutions by the genetic algorithm than common iteration algorithms.

By having the compact structure, the robots had some limitations in locomotion velocity and enduring time. Hence, a mother-son robot cooperation system was proposed to solve these limitations. A novel amphibious spherical robot was designed as the mother robot to carry the microrobots as son robots for collaboration. The spherical mother robot consisted of a sealed hemispheroid, two openable quarter spherical shells, a plastic circular plate, a plastic shelf for carrying microrobots and four actuating units. Each unit was composed of a water jet propeller and two servo motors, each of which could rotate 90° in horizontal or vertical direction respectively. The robot could implement on-land locomotion, as well as underwater locomotion. In this paper, we developed the prototype mother robot and did the force analysis of the actuating system in horizontal direction and vertical direction. And plenty of underwater experiments of the robot in the semi-submerged state were conducted to evaluate the underwater performance, including the moving forward experiments in the moving forward experiments of the robot actuated by two main actuating units and four actuating units. From the results of the underwater experiments, we got a maximal moving forward velocity of 13.7 cm/s under the efficient actuating and a maximal rotating velocity of 64.3°/s under a duty of 100%.","PeriodicalId":250844,"journal":{"name":"2013 IEEE International Conference on Information and Automation (ICIA)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132228297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
