Abstract

The invention discloses a three-dimensional object modeling method and device, an image processing device and a medium. The method comprises the following steps: extracting a plane contour of each panoramic image in a three-dimensional space; normalizing the scale of the camera position and the scale of the plane contour of each panoramic image in the three-dimensional space to obtain the normalized plane contour of each panoramic image in the three-dimensional space; and rotating and translating the three-dimensional point coordinates of the planar contours of the panoramic images subjected to scale normalization in the three-dimensional space based on the positions of the cameras so as to unify the three-dimensional point coordinates into the same coordinate system, and splicing the object contours into a multi-object planar contour. The high-resolution panoramic images are used, so that the resolution of a model constructed for the three-dimensional object can be improved, multi-contour splicing and subsequent multi-contour optimization are carried out through coordinate transformation, the object modeling precision can be improved, and the resolution and accuracy of the generated model of the three-dimensional object can be effectively improved.

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...
