一种基于视频流的动态地图构建方法

A dynamic map construction method based on video stream

地图是现实世界的缩影,以其直观性、一览性、可量测性等特征成为人们认知世界的有力工具。随着计算机技术、通信技术等的发展,地图的载体、形式和内涵都发生了巨大的变化。视频作为一种实时性强、场景还原度高的多媒体数据集,是多方位、实时感知现实世界方式,也是对客观环境最真实、直观的表达形式之一,为地图的动态表达提供了可能。本文提出了一种根据摄像头位姿及其内参数构建动态地图的方法。

Map is the epitome of the real world,and it has become a powerful tool for people to know the world with its intuitiveness,readability and measurability.With the development of computer technology and communication technology,the carrier,form and connotation of maps have changed greatly.Video,as a multimedia data set with strong real-time performance and high scene restoration degree,is a multi-dimensional,real-time perception of the real world,and also one of the most authentic and intuitive expressions of the objective environment,which provides a possibility for dynamic expression of maps.This paper presents a method of constructing dynamic map based on camera pose and its internal parameters.
