PANUM'S AREA MEASUREMENT METHOD, APPARATUS, AND WEARABLE DISPLAY DEVICE

摘要

A panum's area measurement method includes: projecting a first parallax image of a spatial object to the left eye of a user under test, and projecting a second parallax image of the spatial object to the right eye of the user under test, the first parallax image comprising a first homologous point and the second parallax image comprising a second homologous point; adjusting a horizontal parallax amount between the first homologous point and the second homologous point until the user under test observes the spatial object producing a ghost; acquiring a parallax amount parameter Δn_e; calculating a horizontal physical spacing Δx between the first homologous point and the second homologous point based on the parallax amount parameter Δn_e; and calculating a panum's area range (μ_in, μ_out) of the user under test based on the horizontal physical spacing Δx.
