Based on the in-depth study of international bilateral relations , this paper designs a set evaluation system for the expert to measure international bilateral relations, based on multi-attribute group decision-making methods and triangular fuzzy number theory ,this paper also designs a model to solve the problem. through the attribute score, establish property and expert weight, linear weighted comprehensive determination to get the sort of bilateral relations between the countries with relatively intuitive.
Abstract:In order to solve the problem of lacking depth information of monocular SLAM, this paper proposes a method of delay depth initialization based on improved least squares. According to the principle of camera imaging, the robot performs two different observations on the same calibration point respectively, and the triangulation method is used to solve the initial depth information of the target pixel. Aiming at the problem of depth solution caused by the error of monocular wheeled robot, this paper improves the least squares method to estimate the optimal depth of target point, and the simulation experiment is carried out by using Matlab software. The experimental results show that the method proposed in this paper is simple and feasible for monocular SLAM. The method proposed in this paper is very accurate to initialize the depth information of monocular robot and the improved algorithm is superior to the least squares algorithm. Experiments show that the method proposed in this paper can solve the problem of lacking deepth information of monocular SLAM, and having the feasibility of applying to monocular SLAM.
