Functional data are becoming more and more common but fewer literature study high-dimensional functional data test. In this paper, we propose a two-sample testing approach based on the double projection integral, to test the equality of the mean functions of two high-dimensional functional data. The asymptotic distributions of the proposed test statistic under the null and alternative hypotheses are derived, together with the power analysis. In practice, the functional data can only be observed on a set of grid points instead of the whole continuous curves and thus we also discuss the influence of curves reconstruction on the test. Extensive simulation results demonstrate that the proposed test method performs well in a wide range of settings. We further illustrate the utility of the proposed test approach by empirical analyses of two real datasets.
