When commercial remote sensing satellites image water areas, if the satellite observation vector and the solar incident light vector satisfy the condition of specular or near-specular reflection, it is effortless for images of water areas to have excessive brightness or even overflow to pollute the adjacent pixels. The current observation geometric model of water flare is only applicable to the ocean flare, and it could not dispel the inland water flare phenomenon in the commercial remote sensing agile satellite imaging process. This paper proposes a method of effectively avoiding the flare phenomenon in the water region of remote sensing satellite images. By analyzing the relationship between the observation vector of the satellite imaging view axis and the sun light irradiation vector, it provides an imaging angle reference for the commercial remote sensing agile satellite imaging of the earth. This method can effectively eliminate the flare phenomenon in the water area due to the specular or near-specular reflection and guarantee the quality of the commercial remote sensing satellite image of the water application.

摘要

When commercial remote sensing satellites image water areas, if the satellite observation vector and the solar incident light vector satisfy the condition of specular or near-specular reflection, it is effortless for images of water areas to have excessive brightness or even overflow to pollute the adjacent pixels. The current observation geometric model of water flare is only applicable to the ocean flare, and it could not dispel the inland water flare phenomenon in the commercial remote sensing agile satellite imaging process. This paper proposes a method of effectively avoiding the flare phenomenon in the water region of remote sensing satellite images. By analyzing the relationship between the observation vector of the satellite imaging view axis and the sun light irradiation vector, it provides an imaging angle reference for the commercial remote sensing agile satellite imaging of the earth. This method can effectively eliminate the flare phenomenon in the water area due to the specular or near-specular reflection and guarantee the quality of the commercial remote sensing satellite image of the water application.
