Problems solved by technology

[0008] In the technical solution disclosed in Chinese patent document CN200610053842.9, an ordinary camera is used to generate a sequence of static images, and then the sequence of static images is stitched into a 360-degree cylindrical panorama by using software technology. Since this method uses a cylindrical panorama, the method It can only look around at 360 degrees, and cannot view objects from multiple angles. Because this method lacks three-dimensional depth information of objects, it cannot construct a three-dimensional image with a sense of distance.
[0019] b) Disadvantages: the switching of scenes (panora

Embodiment

[0060] In this embodiment, the two-axis automatic acquisition device for indoor panoramic three-dimensional data includes a tripod for a horizontal rotation platform and a pitch rotation platform, a stepping motor for controlling the horizontal rotation angle, a stepping motor for controlling the pitch rotation angle, and a Microsoft Kinect. For commercially available products. Kinect is installed on a tripod, and its horizontal and pitch rotation angles can be adjusted by controlling the stepping motor to complete the collection of panoramic pictures and depth information data in the space to be displayed.

[0061] In this embodiment, the panorama picture is implemented in a cube (Cube) manner. At a certain moment, only a part of the panorama picture (according to the screen size and display ratio) can be displayed on the screen. The 3D model used comes from the model created by the applicant with the 3D scanning method of Kinect.

[0062] The 3D panorama mapping algorithm ...

Abstract

The invention relates to a spatial global 3D view and panoramic image-based space display method. The method includes the following steps that: 1) 3D modeling is carried out, and the texture mapping of a spatial global 3D model is generated based on panoramic images; 2) a three-dimensional graph library is utilized to display the 3D model of a space to be displayed, wherein the 3D model has been subjected to the texture mapping generated in the step 1); 3) panoramic image acquisition is carried out, an indoor panoramic 3D data biaxial automatic acquisition device in the space to be displayed is adopted to acquire the panoramic images of a plurality of preset observation points, and the exact spatial 3D coordinate information of each observation point and the rotation axis information of corresponding panoramic images in the 3D model of the space to be displayed are recorded, wherein the rotation axis information contains zero-degree angle information; 4) the panoramic images obtained in the step 3) are mapped on the 3D model through a 3D panoramic mapping algorithm; and 5) a 3D model display mode and a panoramic image display mode are switched.

Description

technical field [0001] The invention relates to a three-dimensional space display technology using a computer or the Internet, and a comprehensive display method for the displayed space from the overall situation to the details is achieved by combining the three-dimensional data of the space and the panoramic picture. Background technique [0002] The existing spatial display methods mainly include panoramic image display and 3D modeling display. Panoramic pictures lack three-dimensional data, and scene performance lacks a global display. The 3D modeling is divided into manual measurement data modeling based on surveying and mapping and 3D scanning modeling. The model made by the former lacks real structure and texture information, and the scene reality is not strong; although the latter has a realistic spatial structure, the texture details are not perfect. Therefore, the existing space display methods can be mainly divided into: (1) display of panoramic pictures, (2) dis...
