Abstract
Disclosed is an image stitching-based aerial image formation apparatus, including sequentially along an optical path direction: an image source comprising a plurality of display units arranged in an array; a rear lens group comprising a plurality of optical lens units arranged in an array; and a front lens group, wherein light rays passing through the rear lens group are converged via the front lens group to render a real image in midair. The disclosure offers the following benefits: by splitting the image source into a plurality of display units arranged in an array and constituting the rear lens group by a plurality of optical lens units arranged in an array, the image is split into smaller patches, such that the longitudinal distance needed for chromatic aberration adjustment also decreases, which shrinks the longitudinal dimension of the whole apparatus so as to be better adapted for installation in a narrow space.
