交互式全景视频流地图设计

Design and research of interactive panoramic video map

全景视频流地图区别于一般电子地图的特点是将全景视频流数据与空间位置进行配准,不仅视频流数据具有360°全景浏览的特点,而且每帧图像都具有空间化特征。全景视频流地图的关键技术是全景视频三维模型和交互式操作。该文首先介绍了全景视频流地图的定义和系统设计,然后通过实验将视频流投影到以视点为中心的球体,利用Flex三维建模接口建立球型全景视频三维模型。全景视频流地图可以带来更流畅、更具沉浸感的用户感受,它将是街景地图、全景地图的发展趋势,将成为全景地图系统的新一代产品。

Panoramic video map is different from the general electronic map, which matches the pano- ramic video data with the spatial position. The video stream data of panoramic video map has the character- istics of 360~panoramic view, and each frame image has the spatial characteristics. The key technology of panoramic video map is full 3D model and interactive operation. In this paper, the definition and system design of interactive panoramic video map are introduced, and the video stream is projected to the center sphere through experiment, and the 3D model of ball is established by using the Flex 3D modeling interface. Panoramic video map can bring more fluent and immersive user experience, it will be the development trend of street view map and panoramic map, and will become a new generation product of panoramic map system.
