Problems solved by technology

The traditional 3D panoramic image generation method has a single projection method. When aligning images, a phase-based alignment method is often used. The 3D panoramic image generated by the traditional 3D panoramic image generation method is often not smooth enough and cannot be closer to the real scene.

Embodiment Construction

[0037] figure 1 The flow of a method for generating a three-dimensional panoramic image in an embodiment is shown, and the flow of the method includes the following steps:

[0038] In step S10, a plurality of partial images of the panorama are captured. In this embodiment, the wide-angle camera is made to look up and look down at an angle with respect to the horizontal position of the cloud platform to shoot, and the camera lens of the wide-angle camera is rotated every 90 degrees, so that the wide-angle camera shoots four partial images of the panorama at the angle of looking up (such as Figure 10A~10D shown), taking four partial images of the panorama from a top-down perspective (such as Figure 11A~11D shown), a total of eight images form a panorama. Such shooting can increase the overlapping area of ​​the partial images, so that when the partial images are synthesized into a plane composite image, the image effect is smoother, and the obtained three-dimensional panorami...

Abstract

The invention relates to a three-dimensional panoramic image generation method. The method comprises the following steps of: shooting a plurality of local images of a panorama at a low angle and a high angle at a horizontal position opposite to a tripod head by using a wide-angle camera respectively; synthesizing a plane composite image from each shot local image; converting the plane composite image into a three-dimensional spherical image; and performing three-dimensional navigation on the three-dimensional spherical image. By the method, the overlap region of the local images can be increased, so that the image effect is smoother and the obtained three-dimensional panoramic image is more similar to a real scene when the local images are synthesized into the plane composite image. The invention also provides a three-dimensional panoramic image generation system.

Description

【Technical field】 [0001] The invention relates to image acquisition and processing technology, in particular to a method and system for generating a three-dimensional panoramic image. 【Background technique】 [0002] Panorama (Panorama) is a form of representation of virtual reality, which will give users the feeling of entering the scene in the image. A panoramic image refers to an image that includes a larger than the normal viewing angle of the human eye or the peripheral vision viewing angle of both eyes, or even a 360-degree complete scene range. [0003] Compared with general renderings and 3D animations, panorama renderings have the following advantages: 1. It avoids the disadvantages of general planar renderings with a single angle of view, which cannot bring a full range of experience, and the picture effect is exactly the same as that of general renderings during playback; 2. It is highly interactive and can be manipulated by the user to interactively observe the s...
