An improved particle swarm optimization (PSO) method for detecting feature points of large-scale point-based models is presented in this paper. By redefining the particle, fitness, initial and ending conditions, local optimum and global optimum, iterative equations of PSO, this method can search multi-regions for the feature points in an adaptive random and parallel manner. The fitness is defined...
A novel camera calibration approach based on particle swarm optimization (PSO) is put forward in this paper. Firstly, we designed 35 sample points on the calibration box; Secondly, the 3D point and their corresponding 2D image coordinate of these sample points were obtained; In this approach, PSO algorithm was adopted to obtain the camera intrinsic parameters. Among the 35 sample points, 30 points...
