Abstract

The invention discloses an image processing and three-dimensional object modeling method and device, an image processing device and a medium. The image processing method comprises the following steps:estimating the position of a camera and the three-dimensional point coordinates of matched feature points on a panoramic image by utilizing the geometrical relationship of at least one shot panoramicimage; for each panoramic image, through a deep learning model used for extracting an image contour, extracting a plane contour of the panoramic image in a three-dimensional space; and normalizing the scale of the position of the panoramic camera when each panoramic image is shot and the scale of the plane contour in the three-dimensional space of each panoramic image. According to the method, the resolution of the model of the three-dimensional object can be improved by using the high-resolution panoramic image shot by the panoramic camera, and the precision of the preparation data requiredby object modeling can be improved by extracting the plane contour of the image through the deep learning model, so that the resolution and the accuracy of the generated three-dimensional object modelcan be effectively improved.

Description

technical field [0001] The invention relates to the field of image processing and three-dimensional object modeling, in particular to image processing and three-dimensional object modeling methods and equipment, image processing devices and media. Background technique [0002] In the field of 3D object modeling, how to make the generated 3D model have high resolution and high accuracy is the goal pursued by the industry. [0003] There are currently two main ways to model 3D objects. [0004] One is to use a common image acquisition device to take multiple images from different angles, and then combine / stitch the multiple images taken from different angles to form a 3D model of a 3D object. However, when shooting multiple images in this way, the shooting angle and position generally need to be fixed. This shooting method has great defects, and it is often impossible to shoot large three-dimensional objects that cannot be moved, especially for multiple such objects. When mo...
