RETRACTED: Using Sphere Parameters to Detect Construction Quality of Spherical Buildings (Retracted Article)

In this paper we deal with calculating sphere parameters (e.g., spherical center, radius, and circularity) to detect the construction quality of spherical buildings. This procedure consists of three stages: data collection, coordinates transformation, and sphere parameters estimation, respectively. We first performed Matlab to create a sphere surface as the spherical building used in analysis. We then picked up different points located on the surface to estimate the sphere parameters. Finally we discussed the influence of points' distribution and density on the accuracy of parameters estimation. The experimental result indicates our approach with points evenly distributed both in "latitude" and "longitude" can achieve centimeter accuracy.
