IST Generalized Perspective Projection Dataset
收藏资源简介:
IST广义透视投影数据集包含八张来自Salient360!数据集的全景图像,采用等距圆柱格式。图像分辨率分为8K和4K两种,涵盖室内外场景、近远物体及人物存在与否。每张图像针对前视、右45°和左45°三个视角方向生成十种视口,每个视口对应一对(d, FoV)参数,其中d取值为0,0.25,0.5,0.75,1,FoV取值为90°和110°。视口分辨率为856×856像素。
The IST Generalized Perspective Projection Dataset includes 8 panoramic images sourced from the Salient360! Dataset, which are stored in equirectangular projection format. The images are available in two resolutions: 8K and 4K, covering indoor and outdoor scenes, near and far objects, as well as scenarios with or without human subjects. For each input image, ten viewports are generated across three viewing directions: forward, 45° right, and 45° left. Each viewport corresponds to a pair of (d, FoV) parameters, where d takes discrete values of 0, 0.25, 0.5, 0.75, and 1, while FoV takes values of 90° and 110°. The resolution of each generated viewport is 856×856 pixels.
