The bound states of two dipoles in a harmonic waveguide are investigated based on the local frame transformation (LFT) approach. Both the identical Bosonic and Fermionic dipoles are considered. In the weak dipole interaction regime, the length scale separation, which is the key prerequisite for the application of LFT approach, is verified by examing the wavefunction. Comparing the bound state energies obtained from LFT approach with the numerically accurate ones, it is found that, away from the threshold, the LFT approach with single partial wave approximation is accurate enough. Close to the threshold, higher partial wave states are strongly coupled, and more partial wave states should be incorprated in the LFT approach to obtain accurate results.
