Abstract

The invention relates to a method and device for quantitatively correcting algorithm precision. The method comprises an obtaining step: obtaining an original image which is formed by the photographingof a scene comprising one or more standard spheres through a camera lens; a correction step: correcting the original image based on a to-be-evaluated correction algorithm to obtain a corrected image;and an analysis step: extracting one or more correction shapes of the standard sphere in the correction image to obtain the circularity of the one or more correction shapes, and obtaining the precision of the to-be-evaluated correction algorithm according to the circularity of the one or more correction shapes. The precision of the correction algorithm is quantified through the distortion degree,so that a method capable of quantifying the effect of the correction algorithm through numbers is formed.

Description

technical field [0001] The present disclosure relates to the technical field of quantifying algorithm precision, and in particular to a method and device for quantifying and correcting algorithm precision. Background technique [0002] Due to the characteristics of the camera lens, when shooting an object, there is often serious distortion at the edge of the viewing angle. Especially for ultra-wide-angle lenses, this phenomenon is particularly obvious. [0003] In order to solve this shooting problem, various image shape-preserving distortion correction algorithms have been proposed in the industry. However, for the correction results of the corrected image corrected by the image conformal distortion correction algorithm, at present, it is mostly identified by naked eyes, and a method that can quantify the conformal distortion correction effect through numbers has not yet been formed. Contents of the invention [0004] In order to overcome the problems existing in the pr...
