Object panorama modeling method

Abstract

The invention discloses an object panorama modeling method. The method includes the following steps of firstly, conducting camera shooting through a single-view-angle three-dimensional capturing device to obtain a depth image of a current frame and a color image of the current frame, conducting region segmentation according to the depth image to obtain a target region in the depth image, conducting corresponding de-noising processing on the target area, and then converting the target area undergoing the corresponding de-noising processing into a peak image and a normal image; secondly, calibrating the position of the depth image in an overall coordination system through the algorithm of iterating the nearest-neighbor point by calculating the matrix transformation relation between the depth image and a depth image of a previous frame; thirdly, reconstructing the depth image into a three-dimensional model according to the position of the depth image in the overall coordination system; fourthly, infusing color information into the three-dimensional model by combining overall coordinates with the correction relation between the depth image and the color image, and repeating the first step to process an image of a next frame. According to the method, real-time three-dimensional panorama modeling of an object can be achieved through the single-view-angle three-dimensional capturing device.

Description

Technical field [0001] The invention relates to the fields of image processing, three-dimensional image reconstruction and computer vision, and in particular to a method for panoramic modeling of objects. Background technique [0002] In computer vision, three-dimensional reconstruction refers to the process of reconstructing three-dimensional information from single-view or multi-view images. Obtaining the depth information in the image through various methods has always been a difficult point to achieve reconstruction in the past. After Microsoft launched kinect, depth information can be obtained simultaneously with color images, which has also brought tremendous changes to computer vision. [0003] Even if kinect can obtain depth information at the same time, it is still difficult to make a perfect three-dimensional model of the human body or object. A more mature method is to use multiple kinects placed in different directions to simultaneously obtain information for 3D recon...
