Embodiment Construction

[0084] For achieving the purpose of the present invention, technical scheme of the present invention is:

[0085] Step 1: Obtaining Google Maps

[0086] The area mainly discussed in the present invention is the Tianjin area, so utilize the map downloader to download the Google map tiles in the Tianjin area with the operating point as the center and within a radius of 10 kilometers (the Google map is made up of the resolution size called "tiles" All are 256×256 pictures seamlessly spliced). figure 1 is the downloaded original map tile.

[0087] Step 2: Defog

[0088] There are impurities in the air, and the downloaded Google map tiles are not clear. In order to improve the accuracy of recognition, it is necessary to dehaze the obtained Google map tiles first. figure 2 It is the effect picture after removing the fog.

[0089] Step 3: Grayscale

[0090] The Google map after defogging processing is still a color image. In order to identify the location of non-safe areas (po...

Abstract

The invention relates to the technical field of safe fire boundaries in artificial weather modification, and provides a method for automatic identification of non-safe areas and automatic drawing of safe fire boundary maps. This method can automatically identify non-safe areas on Google Maps and automatically draw safe fire boundary maps. It has high drawing efficiency, high accuracy and is easy to promote. The technical solution adopted by the present invention is a method for automatic identification of non-safety areas and automatic drawing of safe fire boundary maps. The steps are as follows: Step 1: Acquisition of Google Maps Step 2: Dehazing Step 3: Grayscale Step 4: Segmentation Step 5 : Denoising Step 6: Map tile splicing. Steps 2 to 6 are the automatic identification process of non-safe areas; Step 7: Automatically draw a safe fire boundary map. The invention is mainly used in artificial weather modification situations.

Description

technical field [0001] The invention relates to the technical field of safe shooting boundaries in artificial weather modification, in particular to an automatic identification of non-safe areas and an automatic drawing method of a safe shooting boundary map. Background technique [0002] my country has a vast territory, complex terrain, and diverse climate types but poor stability, so it is seriously affected by meteorological disasters. Statistics show that in recent years, meteorological disasters have caused hundreds of millions of economic losses to my country every year. In order to reduce the losses caused by meteorological disasters, artificial weather modification is more and more applied to production and life. Artificial weather modification is the use of human factors to intervene in the weather, reduce the adverse effects of meteorological disasters, and use scientific and technological means and climate resources to achieve activities such as artificial rainfa...
