A method and an apparatus for evaluating brightness uniformity of a naked eye three-dimensional display apparatus. The method comprises: controlling a display panel (20) of the naked eye three-dimensional display apparatus to sequentially display N viewpoint images, the display panel (20) comprising multiple sub-pixels; when each viewpoint image is displayed, sub pixels used for displaying a current viewpoint image displaying a white image, sub pixels used for displaying another viewpoint image displaying a black image, and sequentially obtaining brightness values of light rays at M test angles corresponding to the current viewpoint image on a light emergence side of the naked eye three-dimensional display apparatus; determining a brightness peak value of all the obtained brightness values; evaluating the brightness uniformity of the naked eye three-dimensional display apparatus according to the proximity to 1 of the ratio between the brightness peak values corresponding to every two adjacent test angles, N and M being positive integers not less than 2. The evaluation method and apparatus can improve the accuracy of the brightness uniformity of the naked eye three-dimensional display apparatus.
