摘要
利用图像蒙版技术表现场景专题信息,通过将重要的场景专题信息以单一图像的形式罩于地形表面,形成地形"蒙版",使用户只关注蒙版即可获取所需信息,用户可以在最短时间内形成对场景专题信息的总体把握与正确认识。这种方法在一定程度上提高了用户对场景的认知效率与深度。
Information users can reach comprehensive and correct understandings of scene thematic information in the shortest period of time by expressing it through image masking technique realized by covering the terrain surface with important scene thematic information in the form of a single image to form a masking - out, enabling users to access the needed information by reading the masking - out only. This method improves the efficiency and depth of users'understanding of the studied scene to some extent.
