Abstract: In the process of visual sorting, in order to solve the problem that the irregular contour target position is difficult to locate quickly and accurately, and it is difficult to realize the self-defined grab point, a method of target pose detection based on the contour center of gravity edge distance vector and local polar coordinates is proposed. Firstly, the target contour is determined by adaptive edge detection and the comparison of contour moments, and the larger distance direction from the contour center of gravity to the smallest outer rectangle is defined as the direction from the contour center of gravity …to the edge distance vector. The deflection angle of the target is determined by the vector direction and the position of the outer rectangle to detect the deflection angle of the irregular workpiece. On this basis, judge whether the designated point is the relative center of gravity in the local polar coordinate system, and realize the intelligent positioning of the set point on the target by detecting the coordinates of the designated point in the center of gravity positioning. The experimental results show that the method is suitable for complex contour targets, and the positioning results are accurate and the positioning time is short, so it has high engineering application value.

Abstract: Most of the detail structure characteristic information of the texture image is lost due to the space variation during the automatic detection, which reduces the precision of auto detection and precise location. In order to solve the problem, a method based on the ambiguity resolution algorithm is proposed in this article. The background texture information was eliminated via the Gaussian filter and threshold value method to acquire initial rough edge of the defect area. In the stage of precision location, the modified Chan-Vcsc active contour model based on the fuzzy energy was introduced and the precision location for the defect …area was achieved via level set method using the rough edge as the initial curve of the model evolution. Experimental results show that the proposed method can achieve accurate and automatic localization of different types of defect areas, and has high computational efficiency. When the number of samples is 600, the positioning time is only 19 s. When the peak signal-to-noise ratio reaches 100 dB, the absolute error of this method is only 0.01%, the relative error is 0.04%, and the positioning accuracy is as high as 99.58%. Show more

The data of ceramic 3D printing samples were collected and preprocessed by fuzzy algorithm. The specific content of the evaluation index of 3D printing sample data is determined, and the evaluation system of 3D printing sample data is established. Fuzzy algorithm is used to determine the weight of data quality evaluation index of ceramic 3D printing samples. According to the steps of setting up the weight matrix of the evaluation index …of 3D printed ceramic sample data, the weight matrix of the evaluation index is established.

According to the membership function of each evaluation index, the fuzzy set of 3D printing sample data of ceramics is established. Finally, the data evaluation process is designed to realize the data evaluation of ceramic 3D printing samples based on fuzzy algorithm. The experimental results show that the evaluation accuracy of the method is higher than 96%, and the scores of users and experts on the interior design scheme are above 80 points. Show more

Abstract: To ensure that the safety risk indicator system of the south-to-north water diversion project is both scientific and independent, an indicator optimization method based on correlation and sensitivity analysis is proposed. The 3D grey correlation degree among the indicators is obtained by maximum deviation. At the same time, the principal component analysis method is adopted to calculate risk sensitivity based on the preliminary analysis on the risk indicators. The correlation degree reflects whether it is possible for the connotation overlapping between the risk indicators, and the sensitivity reflects the indicators’ influence on the system. The purpose of the research is …to optimize the risk system through removing the less sensitive one of the two relatively correlated indicators, and the calculation results prove the effectiveness and feasibility of the method.

Abstract: Through considering the volatility asymmetry in financial markets, we extend the threshold autoregressive conditional heteroskedasticity model to the general threshold autoregressive conditional heteroskedasticity model with asymmetry. The sufficient conditions for the existence of the stationary solution and the finiteness of the moments of the model are derived. The parameters and the threshold value of the model are estimated using the quasi-maximum likelihood method. The results of Monte Carlo simulation method show that the method performs well. By applying this method to the Shanghai daily return and volatility series with the significant leverage effect, we find that the asymmetric model with …general threshold better reflects the asymmetric fluctuation characteristics than the original model.
