Abstract
The present invention provides a curved surface projection correction method, including the steps of: a projection unit projecting a calibration screen on a projection surface; an image capture unit capturing said calibration screen to define a grayscale image range of said calibration screen, form a binarization image by image binarization, divide the binarization image to a background region and a projection region, define a parallelogram scope as a transform region in said projection region, and define correction parameters by the transform region so as to correspondingly correct projection image which is projected by the projection unit. The present invention can correct projection images of the projection unit to prevent images from distorting, and be able to correct the image projection when applying to a variety of shapes of the projection surface, such as a wall corner, a ceiling joint or a curved projection surface; and the present invention can be hung on a user's chest, be conducive to carry, and achieve convenience and wide applicability effect.
