Embodiment Construction

[0053] Such as figure 1 As shown in Fig. 1, a method for generating remote sensing image samples of construction waste, the overall process is as follows: preprocess the downloaded remote sensing images to obtain two sample data sets, and when the sample sets enter the program, the system will adjust the contrast of the sample sets , and then input it into the generative confrontation network to generate samples. If the sample accuracy reaches the standard and the network reaches convergence, it will be completed.

[0054] Specifically include:

[0055] S1. Remote sensing image preprocessing to create sample data sets

[0056] Such as figure 2 As shown, the sample data set production process is as follows:

[0057] S1.1. Orthorectification

[0058] For orthorectification, select multispectral data as the input data, and select DEM data with a global resolution of 900 meters as the DEM data. The output pixel size is 4 meters. The resampling method is the cubic convolution ...

Abstract

The invention discloses a method for generating a construction waste remote sensing image sample. A downloaded remote sensing image is preprocessed to obtain a sample data set, when the sample set enters a program, a system performs contrast adjustment on the sample set and then inputs the sample set into a generative adversarial network to generate a sample, and if the sample precision reaches astandard and the network reaches convergence, the method is completed. The method solves a problem that there are too few construction waste remote sensing image samples when a remote sensing image isused for construction waste recognition.

Description

technical field [0001] The invention relates to a method for generating remote sensing image samples of construction waste, which is a method for generating remote sensing image samples of construction waste based on generative confrontation networks and LBP operators. Background technique [0002] With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying construction waste is increasing. The amount of construction waste in China has accounted for more than 1 / 3 of the total urban waste. China is in a period of rapid economic development, and hundreds of millions of tons of construction waste are inevitably generated every year. If it is not processed and utilized in time, it will have adverse effects on society, environment and resources. Therefore, the research on intelligent supervision and identification of construction waste is imminent. [0003] For the mainstream deep learning recognition al...
