Abstract

The invention discloses an image comparison method and device based on a three-dimensional engine and a medium thereof, relates to the technical field of computer vision, and is used for comparing whether images are the same image or not. The invention provides an image comparison method based on a three-dimensional engine, and aims to solve the problems that a conventional Euclidean distance mode is complex in calculation, low in efficiency and inapplicable when an image is in a three-dimensional state. An original image and an image to be compared are respectively compressed into a string of codes in a coding compression mode; and the images are compared in a mode of calculating the Hamming distance. The real distance between the pixel points does not need to be calculated pixel by pixel, the calculation is simple, the speed is higher, and the higher image comparison efficiency is further obtained. Besides, no matter a two-dimensional image or a three-dimensional image, the image can be always compressed into a string of codes in a coding compression mode, and then the Hamming distance is calculated, so that the method is suitable for the application scene of the three-dimensional image, and the universality of image comparison and use is improved.

Description

technical field [0001] The present application relates to the technical field of computer vision, and in particular, to an image comparison method, device and medium based on a three-dimensional engine. Background technique [0002] In today's field of computer vision technology, most application scenarios require image comparison, whether in 2D or 3D. At present, image comparison is usually performed by comparing the Euclidean distance of the images. Comparing the Euclidean distance is to compare the real distance between the same pair of coordinate points in the two images. It needs to be compared pixel by pixel to determine whether the two contrast images are consistent, and the calculation is complicated and inefficient. [0003] However, when the image is in a higher-dimensional scene, the calculation of the Euclidean distance is more complicated, less efficient, and has a larger error. In addition, in a three-dimensional scene, there are situations where two points c...
