hello , i have a camera rig, with two camea have no overlap area, they have hardware synchronizated, and i captured two rig images ,use NoncentralRelativePoseSacProblem to solve the relative pose of them whit NoncentralRelativePoseSacProblem::GE, and get some inliers, after that . i use the inliers to solve the relative pose one more time .but some image pair have different result compared to the first solver. transfom may have 10 cm difference,and besides , second solver may reture 0 inliers and 0 transform . so why?
