| 摘 要： | Texture extract from digital aerial image is widely used in three-dimensional city modeling to generate “photo-realistic” views. In this paper, a method based on reforming “Steep edge” curve, which clearly explains how the diffraction of the sunlight makes digital aerial image blurring, is proposed to deblur the texture extraction from digital aerial image, and the experiment shows a good result in visualization and automation.

| Abstract: | Texture extract from digital aerial image is widely used in three-dimensional city modeling to generate “photo-realistic”
views. In this paper, a method based on reforming “Steep edge” curve, which clearly explains how the diffraction of the sunlight
makes digital aerial image blurring, is proposed to deblur the texture extraction from digital aerial image, and the experiment
shows a good result in visualization and automation. |
