Abstract
The invention relates to an automatic calibration method for image arrangement of a naked-eye 3D display screen and electronic device. The method comprise: S1, displaying a first 3D test image on a display screen according to a preset viewing distance, and acquiring a mirror image of the first 3D test image in a flat mirror through a camera, wherein the first 3D test image comprises a first monochrome 3D left image and a black 3D right image; S2, adjusting a 3D display rotation angle and a left-right offset of a display screen according to a preset algorithm, acquiring a mirror image and acquiring the number of effective pixel points of the largest pixel block in each mirror image; S3, taking the 3D display rotation angle and the left-right offset corresponding to the mirror image to which the selected maximum effective pixel point number belongs as calibration parameters.
