已知的是，大的远端表面（诸如山丘）的感知倾斜被夸大，并且夸大随着距离而增加。在一系列的两个实验中，我们参数化地研究了观看距离和倾斜感知倾斜使用高保真虚拟环境的效果。分别采用显式数值估计方法和隐式长宽比方法，对具有不同倾斜度和观察距离的模拟大尺度表面在注视方向固定的情况下的感知光学倾斜度进行了评估。结果表明，感知的光学倾斜随着观看距离的增加而增加，并且对于浅倾斜，增加成比例地更大。在每个观看距离处，感知到的光学倾斜可以近似地由跨距离平行的实际倾斜的线性函数拟合。这些线性函数证明了约1.5的相当恒定的增益和随距离几何学增加的截距。一个全面的三参数模型的基础上，目前的数据提供了一个很好的适合一些以前的经验观测测量真实的环境。
It is known that the perceived slants of large distal surfaces, such as hills, are exaggerated and that the exaggeration increases with distance. In a series of two experiments, we parametrically investigated the effect of viewing distance and slant on perceived slant using a high-fidelity virtual environment. An explicit numerical estimation method and an implicit aspect ratio approach were separately used to assess the perceived optical slant of simulated large-scale surfaces with different slants and viewing distances while gaze direction was fixed. The results showed that perceived optical slant increased logarithmically with viewing distance and the increase was proportionally greater for shallow slants. At each viewing distance, perceived optical slant could be approximately fit by linear functions of actual slant that were parallel across distances. These linear functions demonstrated a fairly constant gain of about 1.5 and an intercept that increased logarithmically with distance. A comprehensive three-parameter model based on the present data provides a good fit to a number of previous empirical observations measured in real environments.
