Embodiment Construction

[0028]In order to better illustrate the solar flare stripping method based on polarization remote sensing detection involved in the present invention, the self-developed LCVR polarization imaging multispectral detector was used in Haidian, Beijing on October 17-20, 2012. A long-term multi-scenario water surface detection test has been carried out on the open lake of Zizhuyuan Park in the district, and good results have been achieved. See figure 1 , the specific implementation method is as follows:

[0029] Step 1: Select the appropriate weather conditions, the weather is required to be clear, and ensure that there is strong direct sunlight incident on the water surface, which can form solar glare on the water surface; this test is carried out on October 17-20, 2012;

[0030] Step 2: Choose a suitable location. The water surface is required to be open, and there are no large buildings and trees around to ensure that the test can be carried out when the solar altitude angle is l...

Abstract

The invention relates to a wave water surface sun glitter stripping method based on polarization remote sensing detection, comprising the following four steps: step one, selecting proper time and point to carry out a water surface polarization remote sensing test; step two, selecting proper instruments to acquire a wave water surface sun glitter area time sequence polarization image; step three, processing a wave water surface sun glitter area polarization image; and step four, stripping wave water surface sun glitter. The method is a convenient and efficient wave water surface sun glitter correction method, and has the advantages of being high in precision and good in real-time without causing image data loss or relying on detection angle selection, and the like; and the method has extremely important application values in the fields of dynamic monitoring of sea surface ships, underwater target detection, water color remote sensing, and the like.

Description

technical field [0001] The invention relates to a solar flare stripping method based on polarization remote sensing detection, which belongs to the technical field of remote sensing data processing methods and applications, and has very important significance in the detection and tracking of sea surface targets and the quantitative application of water environment remote sensing data. Background technique [0002] A calm water surface can be approximately regarded as a mirror. When sunlight is incident, strong reflected radiation is formed in the reflection direction symmetrical with the incident direction about the normal, forming solar flare. When there are waves on the water surface, the water surface forms an inclination angle, and a flash point is formed at the top of the waves, forming a larger solar flare area. The solar flare has a large radiation intensity, and when the remote sensor directly observes the solar flare area, it is easy to appear saturation phenomenon....
