The invention provides an image-processing method and device. The image-processing method comprises steps of: extracting a target marker and the two-dimension coordinates of at least three target position points in the target marker from a target image; acquiring the two-dimension coordinate of a user-appointed rendering position point; converting the two-dimension coordinates of the rendering position point and the target position points into three-dimensional coordinates; converting the three-dimensional coordinates corresponding to the target position points into first matrixes and converting the three-dimensional coordinates corresponding to the rendering position point into second matrixes; computing a conversion quantity between each first matrix and the second matrix, and converting the first matrixes into third matrixes based on the conversion quantities, and on the basis of the acquired at least three three-dimensional coordinates converted from the at least three third matrixes, rendering at least one virtual model onto a plane formed by the at least three three-dimensional coordinates. The method and the device may identify one plane by one marker and achieve seamless splicing of an image and the virtual model.
Description
technical field [0001] The present application relates to the technical field of image processing, and more specifically relates to an image processing method and device. Background technique [0002] Augmented reality (AR, Augmented Reality) is to superimpose virtual objects into the real environment to achieve virtual fusion effect. [0003] In the augmented reality system based on visual tracking, in order to achieve real-time and robust tracking effects, it is necessary to pre-arrange markers in the scene to solve the tracking problem by using markers. In practical applications, it is generally necessary to identify multiple landmarks in images captured in the real environment, and determine the coordinates of these multiple landmarks; after obtaining the coordinate system of the virtual object in the virtual model, through the correspondence between the coordinate systems relationship, and render the virtual model to the plane where the image is located to achieve seam...
