月球地形特征认识及增强可视化

Cognition and Enhanced Visualization of Lunar Topographic Features

  • 摘要: 长期以来人们生活在地球上,已形成了基于地球的习惯式视觉感受与空间认识,对其他星体地貌与现象的认知和识别成为新的挑战。基于月球与地球地形地貌上的差异性认知,研究地球认知转移的月球地形地貌的增强可视化,能够让人们更加直观地认识月球地形地貌。对比分析月球与地球的地形在地貌类型、地表色彩体系和地形起伏的异同性,建立基于地球认知转移的月球地形增强可视化的认知基础;构建月球与地球地形可视化要求的相似性和差异性,对撞击坑、月海、月陆、月溪等月球的典型地貌和区域地形进行了晕渲参数调整,分析月球地形在不同参数下的晕渲效果,实现月球地形增强晕渲可视化;揭示了月球地形可视化既要借鉴地球可视的认知转移(如暗色-低地形,亮色-高地形),又要打破地球特定思维造成的可视化误解(如白色-雪线、绿-植被),制作符合月球自身特征的可视化体系。

     

    Abstract:
      Objectives  Enhancing people's cognition of the planetary topography becomes an important task of planetary exploration. People living on the Earth have formed visual experiences and spatial cognition based on the Earth environment. It is a challenge to recognize and identify the landforms and phenomena of other planets. With the analysis of the different cognition of the topography between the Moon and the Earth, the enhanced visualization of the moon topography based on the earth cognitive transfer can make us more intuitively understand lunar cartography.
      Methods  We compare the similarities and the differences in topography and color system between the Moon and the Earth to build the cognition transferring from the Earth view to the Moon view, constructs visualization requirements with its similarities and differences between the Moon and the Earth.
      Results  We formulate a scheme to enhance the visualization of the moon's topography according to people's existing cognition habits of the Earth's geomorphology, and take the lunar typical landforms, including the crater, the mares, the highlands and the riles, and lunar regional topography as examples to shade with different shading parameters (altitudinal angle and azimuth angle) and get corresponding shading effects.
      Conclusions  We discover the visualization similarities and the differences between the Earth and the Moon with cognition transferring, and discover the enhanced moon visualization should utilize the similarities to meet our rapid visual thinking and break certain particular rules of the earth topographic visualization (like snow line) to illustrate lunar terrain characteristics.
