Abstract

The invention discloses a three-dimensional object modeling method and equipment, an image processing device and a medium. The method includes: extracting the plane profile of each panoramic image in three-dimensional space; normalizing the scale of the camera position and the scale of the plane profile of each panoramic image in three-dimensional space to obtain the normalized The plane outline of the panoramic image in the three-dimensional space; based on the camera position, the three-dimensional point coordinates of the plane outline in the three-dimensional space of the scale-normalized panoramic images are rotated and translated to unify them into the same In the coordinate system, the contours of each object are spliced ​​into a multi-object plane contour. By using high-resolution panoramic images, the resolution of the model constructed for the three-dimensional object can be improved, and the multi-contour stitching and subsequent multi-contour optimization through coordinate transformation can improve the accuracy of object modeling, thereby effectively improving the The resolution and accuracy of the resulting model of the 3D object.

Description

technical field [0001] The invention relates to the fields of image processing and three-dimensional object modeling, in particular to a three-dimensional object modeling method and equipment, an image processing device and a medium. 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, this method requires complex image stitching, and it is difficult to obtain high-accuracy 3D targets. [0005] Another way is to directly use a 3D scanning device to obtain a 3D point cloud of a 3D object, and then stitch the 3D point cloud to generate a 3D model. However, the image acquisi...
