Embodiment Construction

[0034] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Such as figure 1 As shown, a road protection intelligent early warning method fused with AI vision algorithm includes the following steps:

[0036] S1: Build a guardrail recognition model based on the AlexNet network structure model.

[0037] The input of the AlexNet network structure model is 227*227*3, including 8 weighted layers in total, the first 5 layers are convolutional layers, and the remaining 3 layers are fully connected layers; the activation function is the ReLU function: f(x) =max(0,x); x is the data of the input neuron.

[0038] Initialize the hyperparameters of the AlexNet network structure model including size, step size, filling number, etc.; and set the threshold at the same time.

[0039] S2: Obtain a large number of complete guardrail pictures, select part of the complete guardrail pictures as the training set, a...

Abstract

The invention relates to the field of road early warning, and discloses a road protection intelligent early warning method and system combined with an AI visual algorithm, and the method comprises the following steps: constructing a guardrail recognition model based on an AlexNet network structure model; obtaining complete guardrail pictures, selecting a part of the complete guardrail pictures as a training set, and taking the rest part as a test set; preprocessing the complete guardrail pictures in the training set, then based on the characteristics of consistency and integrity of the guardrail, carrying out image segmentation on the complete guardrail picture by adopting a K-means clustering method, segmenting the guardrail from the complete guardrail pictures, and marking parts of the guardrail pictures; carrying out self-supervised learning and training on the guardrail recognition model by adopting a method based on consistency regularization and a pseudo tag, and optimizing the guardrail recognition model through a loss function comprising a supervised loss item and an unsupervised loss item; and acquiring a real-time guardrail picture, and judging whether the guardrail is damaged or not.

Description

technical field [0001] The invention relates to the field of road early warning, in particular to an intelligent early warning method and system for road protection integrated with AI vision algorithms. Background technique [0002] Highway guardrail is the main form of semi-rigid guardrail, which is a continuous structure that is spliced ​​with corrugated steel guardrail panels and supported by main columns. When the guardrail is collided by a vehicle, it will absorb the collision energy, which is not easy to be crashed, and at the same time can play a very good role in protecting the vehicle and the passengers. [0003] As an important road facility, highway guardrails need to be maintained by people. Once damaged or missing, it will increase the unsafe factors of road driving. The traditional method is to manually drive to patrol, and report after finding a problematic guardrail. However, there are problems with the above-mentioned method. On the one hand, it requires p...
