Abstract

The present disclosure relates to a method and device for quantifying the accuracy of a correction algorithm, wherein the method includes an acquisition step, and the acquisition step is to acquire an original image, wherein the original image is an image formed by a camera lens of a scene including one or more standard spheres The correction step is to correct the original image based on the correction algorithm to be evaluated to obtain the corrected image; the analysis step is to extract one or more corrected shapes of the standard sphere in the corrected image to obtain the circularity of one or more corrected shapes, and The accuracy of the correction algorithm under evaluation is derived from the circularity of one or more correction shapes. The accuracy of the correction algorithm is quantified by the degree of distortion, so as to form a method that can quantify the effect of the correction algorithm by numbers.

Description

technical field [0001] The present disclosure relates to the technical field of quantization algorithm precision, and in particular, to a method and apparatus for quantizing and correcting algorithm precision. Background technique [0002] Due to the characteristics of the camera lens, when shooting objects, there is often severe distortion at the edge of the viewing angle. This is especially true for ultra-wide-angle lenses. [0003] In order to solve this shooting problem, a variety of image conformal distortion correction algorithms have been proposed in the industry. However, most of the correction results of the corrected image corrected by the image conformal distortion correction algorithm are currently identified by the naked eye, and a method that can quantify the effect of conformal distortion correction by numbers has not yet been formed. SUMMARY OF THE INVENTION [0004] In order to overcome the problems existing in the prior art, the present disclosure provi...
