Embodiment Construction

[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] In recent years, with the rapid development of computer technology, deep learning has been widely used in many fields such as computer vision, speech recognition and natural language processing. Convolutional Neural Networks (CNN, Convolutional Neural Networks) is currently the most studied and most mature model in deep learning. It has been successfully applied in high-resolution remote sensing image classification, feature extraction, and scene recognition. However, CNN model training requires the use of a large number of labeled samples. Only when the number of training samples is large enough and the network structure is relatively complex can it show excellent performance; and in the absence of training samples, the network is prone to overfitting. The combination and fall into the local optimal solution and so on.

Abstract

The invention relates to the technical field of highway geological disaster identification, and discloses an unmanned aerial vehicle image highway geological disaster identification method based on pre-training DCNN, which comprises the following steps: S1, acquiring an unmanned aerial vehicle remote sensing image in a highway domain range, and preprocessing the unmanned aerial vehicle remote sensing image to obtain an absolutely oriented ortho-image; S2, segmenting the preprocessed unmanned aerial vehicle remote sensing image by adopting a mean shift algorithm considering image texture features; and S3, taking the segmented unmanned aerial vehicle remote sensing image data as input data, and applying the input data to the trained highway geological disaster identification model to obtaina highway geological disaster identification result. The unmanned aerial vehicle high-resolution image is adopted, the image is segmented based on the mean shift algorithm considering the texture characteristics, the segmented image unit serves as input data of the geological disaster recognition model, so the efficiency of existing geological disaster visual interpretation can be effectively improved, and data support is provided for highway field investigation and disaster risk evaluation.

Description

technical field [0001] The invention relates to the technical field of highway geological disaster identification, in particular to a method for identifying road geological disasters based on pre-trained DCNN. Background technique [0002] Due to its long belt-like distribution characteristics, highway engineering inevitably needs to cross different types of geomorphic units during construction, involving various complex terrain and geological conditions, and is easily affected by the geological environment along the line. Especially after mountainous roads are washed or infiltrated by rainwater, it is very easy to induce geological disasters such as collapses, landslides, and mud-rock flows. According to statistics, the losses caused by road geological disasters in our country amount to several billion yuan every year, causing huge losses to people's lives and national property. Geological disasters seriously threaten the normal operation of road transportation infrastructu...
