立体视觉技术的相关专利分析

Patent Analysis Report on Stereo Vision Technology

立体视觉是指从多个视点去观察同一场景,获得在不同视角下的一组图像,然后通过不同图像中对应像素间的视差,推断出场景中目标物体的空间几何形状和位置。笔者基于中国专利文摘数据库(CNABS)中的相关专利数据,介绍了与立体视觉技术有关的专利申请基本情况,归纳和总结相关专利申请的申请量趋势、在华申请的区域构成、中国大陆申请地域分布分析、专利申请技术领域构成分析,同时分析了立体视觉技术的关键技术领域及未来的发展方向。

Stereo vision means to get multiple 2D-views of a scene from different view directions by observing the scene from different viewpoints, extract the shapes and positions of the objectives in the scene by analyzing the pixel parallax in the different 2D-views. This paper is based on the related patent data from CNABS database. The basic situations of patents in this domain are introduced, and the trends of patent applications, Chinese patents applications distributing in different countries and China Mainland areas are summarized. The formation of technology domain of patents applications, the critical technology domain and trends of stereo vision are also analyzed.
