By enhancing the geometric constraints of the feature points which attached to the target previously, we obtain the three-dimensional camera coordinates of the feature points in two different formulas. Then the translation vector and three rotation angles describing the relationship between target coordinate system and camera coordinate system are computed using a closed-form solution directly. In order to improve the precision about the extraction of the image center coordinate of the feature point, we use the morphology expansion operation to achieve it. The experimental results and theoretical analysis which were compared with the previous method demonstrate that our method is more fast and effective.","PeriodicalId":422587,"journal":{"name":"2015 International Conference on Control, Automation and Robotics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117051319","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}

In this paper, our goal is to localize a target based on range measurements obtained using a network of sensors scattered in the 3D continuum. To this end, we make use of the biologically inspired particle swarm optimization (PSO) algorithm. In this context, we propose a novel modification of PSO algorithm that leads to faster convergence, and eliminates the flip ambiguity encountered by coplanar sensors. Our initial results over several simulation runs highlight the accuracy and speed of the proposed approach. This paper also proposes a statistical approach to optimally place a given set of sensors such that the localization error is minimized over certain trajectories of the target. The optimal locations of the sensors are estimated using the Cramer-Rao lower bound (CRLB) as the cost function.","PeriodicalId":422587,"journal":{"name":"2015 International Conference on Control, Automation and Robotics","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116621518","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 standard weights of pineapple are divided into 10 levels (A-J) and the standard sizes of pineapple are categorized into two classes (class I and class II). The developed tool consists of hardware components and a grading software program. The control light source box was constructed for camera and load cell installation to capture pineapple image and measure pineapple weight, respectively. The obtained image was sent to software program to change colors of the image into gray scale and to reduce noises in the image. The clearly edges of the image were employed to compute size of a pineapple and the data were transferred to fuzzy system. The inputs of fuzzy system determined the size and weight of pineapple which used to establish twenty fuzzy rules. The experiments performed by random selection size and weight of three pineapple kinds including Nanglae, Sriracha, Phuket. The experimental results reveal that classification of pineapple by the created tool exhibited high accuracy of size and weight detection equaled 87.5%. The average relative error performed 2.30% and 5.24% of size and weight, respectively.","PeriodicalId":422587,"journal":{"name":"2015 International Conference on Control, Automation and Robotics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129570653","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}

This technique involves the analysis of a wide range of control system analysis and design problems for uncertain systems which are amenable to solve the numerical problems in efficient way if the requirements regarding robustness are imposed in probabilistic sense within the paradigm. The output voltage of the converter can be affected by changes in load current. This variation in load appears as a linear uncertain parameter, with a known range, in the dynamic model of the converter. Maintaining the output voltage to the desired value in the presence of load variations is formulated as an LPV H-infinity optimization problem. However, instead of covering the entire uncertainty set using the conventional polytopic approach, we use the scenario based approach to extract the scenarios by explicitly and providing the bound on the number of scenarios, resulting in a design to guarantee an a-priori particular probabilistic robustness in design of control problem for DC-DC Buck Converter. This results in a marginal improvement in transient performance, with regard to overshoot and settling time, of the closed loop system. Numerical simulations are performed to demonstrate the above, and a comparison with the LPV polytopic approach and linear PID control is presented.","PeriodicalId":422587,"journal":{"name":"2015 International Conference on Control, Automation and Robotics","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114540070","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}

Majority of the path planning algorithms get stuck in non-convex obstacles pertaining to local minima.

This paper presents a particle swarm optimization based path planning algorithm developed for finding a shortest collision-free path for a mobile robot in an environment strewed with non-convex obstacles. The proposed method uses random sampling and finds the optimal path while avoiding non-convex obstacles without exhaustive search.

Our approach starts with the ISM to define the proposed centers of people locations. Then we utilize a novel method to detect people based on the density of the concentrated proposed centers by using an auto generated threshold mechanism. Our method is easy to implement and does not require complicated computations; thus resulting in a considerable increase in the speed performance and decrease in the cost of the required hardware on mobile platforms. We evaluated our system by testing it on three image sets for indoor and three for outdoor scenarios taken from four databases. Our system showed promising results in detecting people on images taken by different types of thermal cameras under difficult scenarios. This technique will be used as the vision system for a rescue assist mobile robot currently being built at Flinders University.","PeriodicalId":422587,"journal":{"name":"2015 International Conference on Control, Automation and Robotics","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132463533","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}

At first, toll expressway financial risk indexes were designed, which considered not only the current but also the potential solvency about the payment ability of each toll expressway project. Secondly, four risk levels and alerting values were defined by means of those indexes estimation. Meanwhile, corresponding actions were suggested according to risk levels. Thirdly, the decision support system (DSS) was developed on toll expressway financial risk monitoring, and a case study was conducted as well. In the case study, the financial risk level of each project was easily identified by different colors, such as red standing for serious situation.
