A test method is provided for making it possible to acquire distance information of a compound-eye distance measuring device. A chart (C1) used for a compound-eye distance measuring device to acquire distance distribution information through a parallax difference between a plurality of image picking-up optical systems includes a two-dimensional array disposition of a predetermined geometric pattern, for example, a circular pattern (A0). Every disposition direction is set to define a predetermined angle (?1, ?2), so that a pitch of a base line direction of the geometric pattern, the image of which is formed on an image forming plane of the image picking-up optical system, is set to be larger than a parallax difference obtained from a distance measuring range. |
