摘要/Abstract

摘要： 三维全景(Three Dimensional Panorama)是使用全景图像表现虚拟环境的虚拟现实技术,又称虚拟现实全景。该技术通过将全景图进行逆投影至几何体表面来复原场景空间信息。基于CPRS和DWPI专利数据库,对三维全景图像显示技术的专利申请进行了检索,对该领域的专利申请量、专利申请分布、重要申请人和相关核心专利等进行了统计分析,并列举了各技术分支的典型技术方案,为该领域的技术发展提供了一定的参考。

关键词: 国际专利分类, 三维全景, 专利地图, 专利分析

Abstract: Three Dimensional Panorama is a virtual reality technology that uses the panoramic images to represent virtual environments,also called virtual Reality panorama.This technique restores the space information of the scene by reverse projection of the panorama to the surface of the geometric body.Based on the patent database of CPRS and DWPI,the patent applications of the 3D panoramic image display technology are retrieved.The statistical analysis has been made on the amount of patent applications,the distribution of patent applications,the important applicants and the rela-ted core patents in this field,and the typical technical schemes of various technical branches are enumerated ,which provide some reference for the development of the technology in this field.

Key words: International patent classification, Patent analysis, Patent map, Three dimensional panorama
