Here we provide a model for the deprojection of the surface brightness profile specially to cover inner region of a barred galaxy. We consider axisymmetric shape to represent disk component and triaxial shape to describe bulge region. We use GALFIT to decompose our simulated barred galaxy image to bulge and disk parts, then we preform MGE fit to each component separately. Finally we use some constraints to reduce degeneracy due to deprojection then compare intrinsic density distribution of our model with mass density of the mock galaxy. As the test of our model we calculated potential, force components and orbit structure of the mock galaxy and deprojected density which obtained from photometry, Results show this method can be used with confidence for the case of barred galaxies with different observational inclination and position angles.
