摘要：

提出一种基于全景影像的野外虚拟环境快速构建方法, 通过对全景影像进行轮廓识别、深度估计和图像修复等处理, 得到基于图像的场景信息, 根据用户的位置渲染对应的全景图像, 获得支持有限范围内6自由度沉浸式漫游的虚拟野外环境, 并从图像质量的用户主观感受及客观指标两个方面对该方法的实用性进行验证, 证明该方法使用较方便, 具有较好的应用效果, 可用于虚拟化野外地质教学。

关键词: 野外环境, 虚拟地理环境, 全景影像, 6自由度漫游, 图像修复

Abstract:

A fast construction method of field virtual environment based on panoramic image is proposed. Through the processing of panoramic image, such as contour recognition, depth estimation and photo inpainting, the image-based scene information is obtained. The corresponding panoramic image is rendered according to the user’s position, so as to obtain an immersive field virtual environment supporting 6-DOF roaming in a limited range; The practicability of this method is verified by the user's subjective feeling and objective index of image quality. The results show that the proposed method has a more convenient way of use and better application effect, and may be used in virtual field geological practice teaching.

Key words: field environment, virtual geographic environment, panoramic image, 6-DOF roaming, photo in-painting
