5.5 功能概述

The SVS system picks up the view around the body through four cameras and the controller seamlessly stitches the images from the four cameras to form a 360° panorama, displaying a 360° image of the surroundings of the body similar to an image taken from the sky.
SVS系统通过四个摄像头拾取身体周围的视图,控制器将四个摄像头的图像无缝拼接成360°全景,显示身体周围的360°图像,类似于从天空拍摄的图像。
