A method for extracting form factors $N^*$ from the experimental data on cross sections of exclusive reactions $\gamma_{r,v} p \rightarrow \Delta^{++} \pi^{-} $ and $\gamma_{r,v} p \rightarrow p \rho^0$ has been developed. It is shown that the method ensures stable calculation of form factors with an inaccuracy of about 10% if the errors in measuring cross sections of said quasi-two-particle reactions do not exceed 3%.
