Embodiment Construction
[0073] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.
[0074] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way taken as limiting the invention, its application or uses.
[0075] In the embodiment of the present invention, the structural model of the room where the point is located can be reconstructed directly from an RGB color panorama through deep learning. Input an RGB panorama image, output the intersection line of wall-ceiling, wall-floor and the intersection line position of wall-wall in the RGB panorama image.
[0076] There are different points in the existing technical solutions that identi...

The embodiment of the present invention discloses a method and system for optimizing a three-dimensional image, wherein a panoramic image of each position in a room is obtained; according to the points in the panoramic image of each position, a point with the same name describing the same space is obtained, and a point with the same name is generated. point combination; iteratively optimize the pose and scale parameters of the points with the same name in the same-name point combination respectively, and obtain the optimized pose relationship and scale parameters; according to the optimized pose relationship and scale parameters, splicing to form the 3D image of the room described. The solution of the present invention uses a three-dimensional model scale optimization algorithm based on depth image matching to optimize the scale of point clouds of adjacent points. It can stitch all the panoramic images of the room to obtain a three-dimensional image of the whole room.
Description
technical field [0001] The invention relates to the technical field of computer three-dimensional space modeling, in particular to a method and system for optimizing and generating a three-dimensional image. Background technique [0002] In the data acquisition stage of the indoor 3D model, it is generally necessary to use special equipment to collect different shooting point data (including depth data and RGB image data). After the data collection is completed, the RGBD image is obtained through the calibrated camera parameters, RGB image and depth image. Among them, RGB is a color standard in the industry. It obtains a variety of colors by changing the three color channels of red (R), green (G), and blue (B) and superimposing them with each other. Yes, RGB is the color that represents the three channels of red, green, and blue. This standard includes almost all the colors that human vision can perceive. It is one of the most widely used color systems at present. A depth ...
