There are misunderstandings in projection calculations in practical production applications. This paper briefly introduced calculation method of projection and projection distance, listed two common calculation methods in production, pointed out existing issues, prepared relevant procedures, and made a relatively detailed comparative analysis using coordinate data of field actual observation spots. The results indicate that the used algorithm is more reasonable in practical application and effective in guiding production.
