A virtual image evaluation method and a virtual image evaluation device for a head-up display, which evaluate with high accuracy whether or not correction of distortion of a virtual image is achieved in a desired manner. Disclosed is a virtual image evaluation method for a head-up display, which captures an image of a projection target when an inspection image displayed on an image output device is projected onto the projection target, and evaluates the distortion of a virtual image on the basis of the captured image. This method comprises: a step for setting a plurality of target positions corresponding to a plurality of evaluation points for distortion evaluation; a step in which a plurality of reference pixel groups each comprising a plurality of consecutive pixels are arranged in the inspection image in accordance with a plurality of target positions; and a step for setting the pixel value of each pixel constituting each reference pixel group in the inspection image such that the center of gravity (G) based on each pixel value of the plurality of reference pixel groups coincides with or approaches the target position.
一种平视显示器的虚像评价方法及虚像评价装置,其高精度地评价是否以所希望的方式实现虚像的失真的校正。所公开的平视显示器的虚像评价方法,其对将显示于图像输出器的检查用图像投影到投影目标体时的投影目标体进行摄像,根据拍摄图像评价虚像的失真。本方法包括:设定与失真评价用的多个评价点对应的多个目标位置的工序;在检查用图像中,根据多个目标位置配置分别由连续的多个像素构成的多个基准像素组的工序;以及以基于多个基准像素组的各个像素值的重心G与目标位置一致或接近的方式,设定分别构成检查用图像中的基准像素组的各像素的像素值的工序。
