VerifyRealRoots is a Matlab package for computing and verifying real solutions of polynomial systems of equations and inequalities.It calls Bertini or MMCRSolver for finding approximate real solutions and then applies AINLSS to verify the existence of a regular solution of a polynomial system or applies AINLSS2(AIVISS)to verify the existence of a double solution(a singular solution of an arbitrary multiplicity)of a slightly perturbed polynomial system. 展开更多

A complete solution classification of the perspective-three-point(P3P) problem is given by using the Gr?bner basis method. The structure of the solution space of the polynomial system deduced by the P3P problem can be obtained by computing a comprehensive Gr?bner system. Combining with properties of the generalized discriminant sequences, the authors give the explicit conditions to determine the number of distinct real positive solutions of the P3P problem. Several examples are provided to illustrate the effectiveness of the proposed conditions. 展开更多
