The Reproduction and Evaluation of Star Fields with the Milky Way in a Planetarium

In this study, we investigated the physical factors required to accurately reproduce Milky Way in star fields a planetarium using three evaluation indices: faithfulness, preference, and depth feeling. Psychometric experiments were conducted by manipulating different (transmittance, representation size density) of stars projected on dome screen as experimental stimuli. The indices rated observers for 12 reproductions Way. By analyzing results, developed common model estimate scores each index changing coefficients factors. Our proposed has good accuracy, can be represented transmittance, density. weighting values indicate that density reproduction was pivotal factor majority observers. contrast, not affected
