In article the way of rejection of roughly measured points of digital space pictures at creation is offered of district model on them with use of elements of mutual orientation (EVZO) of a stereo pair.
For definition of EVZO use not less than 6 couples (corresponding) points of the same name of a stereo pair of pictures and the solution of a task of a method of the smallest squares consecutive approximations. But as the method of the smallest squares is sensitive to roughly measured points, such points need to be defined and excluded from computing process. Usually for this purpose after each approach find residual cross parallaxes of the points of the same name on an ideal stereo pair which calculate on the transformed ordinates of such points which is carried out on EVZO of pictures. A lack of this way is that for rejection is inexact the identified points is used errors only of ordinates of corresponding points while their situation is influenced also by abscissae. If to use for the solution of the designated task a corner between normals to the basic plane in which there are corresponding points, this shortcoming is excluded. In it the essence of the offer also consists. For calculation of vectors of normals to the basic plane use coordinates of corresponding points and coordinate of the second center of a projection (basis of design). As on a vector of basis the normal to the basic plane in which they are are result of vector work of each of two vectors, both normals have to be parallel each other, and the corner between them has to equal to zero. On a deviation of value of this corner from zero rejection of roughly identified points is also made. Theoretical provisions of the offered way are confirmed with results of experiment which is executed on model and on real pictures. Results of experiment only on model pictures are given in article.
