Abstract
A chromatic aberration defect compensation data determination method, a chromatic aberration defect compensation method, and an augmented reality device. The chromatic aberration defect compensation data determination method comprises: acquiring an imaging image of an augmented reality apparatus, and preprocessing the imaging image to obtain a first image; using a preset filtering algorithm to perform chromatic aberration defect detection on the first image; obtaining the position of a chromatic aberration defect region and chromatic aberration defect data; and generating corresponding chromatic aberration defect compensation data on the basis of the chromatic aberration defect data. The augmented reality apparatus can execute the method; the position of the chromatic aberration defect region and the corresponding chromatic aberration defect compensation data are determined by means of a detection result of the preset filtering algorithm, and then the display content of the augmented reality display apparatus is compensated, so as to obtain a compensated display picture, thereby improving the display effect of the augmented reality display apparatus, and correcting chromatic aberration.
