Abstract

The present invention provides a method and a device for verification applied to the field of image processing. The method includes: acquiring a common two-dimensional image, an infrared image and a depth map of a calibration object, wherein the calibration object carries a first pattern; calculating coordinates of an image formed on the infrared image by the first pattern, acquiring a depth value of the first pattern according to the depth map, and calculating a position of a projection formed on the common two-dimensional image by a three-dimensional point cloud corresponding to the image formed on the infrared image by the first pattern, and calculating a distance between an image and the projection formed on the common two-dimensional image by the first pattern. The method and device for verification provided by the present invention can verify a calibration parameter obtained after calibration performed by a depth camera device, enhancing calibration accuracy.
