Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0020] see Figure 1~2 A video-based waterlogging detection method, which first collects sample pictures with a large amount of road waterlogging, and then uses the labeling tool to label the sample pictures, and then trains the labeled sample pictures based on the SSD target detection algorithm to construct a product Water detection model; finally obtain the video stream data of the road camera, and use the constructed water accumulation detection model to detect the accumulation of water on the obtained road camera video stream data. The specific steps are as follows:

[0021] 1) Collect sample pictures

[0022] Collect 1000 sample pictures with a lot of road water;

[0023] 2) Label sample pictures

[0024] Use the labeling tool LabelImag ...

Abstract

A video-based ponding detection method comprises the steps of firstly collecting a sample picture with a large amount of road ponding, then labeling the sample picture through a labeling tool, training the labeled sample picture based on an SSD target detection algorithm, and constructing a ponding detection model; and finally, acquiring video stream data of the road camera, and performing ponding detection on the acquired video stream data of the road camera by using the constructed ponding detection model. According to the method, sample collection, sample labeling, target detection and deep learning technologies are effectively combined with an actual road scene, the road waterlogging state is accurately recognized, the recognition accuracy is greatly improved, large-scale application can be performed by means of the constructed video monitoring network, and certain economic benefits and use values can be created.

Description

technical field [0001] The invention relates to the technical field of video intelligent monitoring, in particular to a method for detecting water accumulation based on video. Background technique [0002] In the city, the water accumulation on the road seriously affects the traffic order, and there are potential safety hazards, which endanger the safety of the people. It takes a lot of manpower and financial resources to clean up the water accumulation. If the water accumulation on the road can be found in time and actively dealt with, the loss can be minimized to the greatest extent. At present, the commonly used detection methods are: 1. Using the road to install the water detection device, this method is expensive to install, and it is difficult to fully promote; 2. By analyzing the camera video image, based on the texture characteristics of the water and the SVM classification method to detect the water Detection, feature selection single. Contents of the invention ...
