Embodiment Construction

[0028] The invention introduces deep learning into road event recognition and improves it, which can significantly improve the accuracy of road event recognition. Considering that the background modeling method is not suitable for static object detection, and the pavement remnants are difficult to use the prior model to construct the training set. The invention establishes the detection of road remnants based on deep convolutional neural network Deep-CNN. The detection point of the mobile terminal is a road camera, and the detection point of the mobile terminal obtains image information through the camera, and the CNN neural network is used to analyze the obtained image. The present invention Divide the pavement ROI area into multiple networks, build a pavement-non-pavement recognition model, and reversely identify static targets such as highway pavement remnants and road spills through non-pavement grids.

Abstract

The invention discloses a road surface abandoned object detection method based on a deep convolutional network. Mobile terminal detection points serve as road cameras and acquire image information through cameras, and deep learning is introduced into road surface event recognition and is improved so as to significantly improve road event recognition accuracy. According to the method, acquired images are analyzed through the convolutional neural network, and target detection with mobile cameras and static images is achieved; a road surface ROI is divided into multiple meshes, a road surface-non-road surface recognition model is built, and static targets such as highway surface abandoned objects and thrown objects are reversely recognized through non-road surface meshes. The method is applied to non-real-time tasks like detection of road surface abandoned objects and thrown objects, the characteristics and advantages of the mobile internet are fully utilized, and detection of road surface events like road surface abandoned objects with a high region coverage rate is achieved at a low cost.

Description

technical field [0001] The invention belongs to the technical field of video detection of depth features, relates to the detection of road events, detects the remnants of the road based on the Deep-CNN road reverse recognition model, and performs data analysis and data mining on the detection results. A neural network (Deep-CNN) detection method for pavement remnants. Background technique [0002] Road accidents, traffic congestion, and environmental pollution are common problems faced by the development of today's road traffic. Road traffic safety is worrisome. Road informatization and Intelligent Transportation System (ITS) are effective means to improve the utilization efficiency of road facilities, alleviate traffic congestion, and reduce the incidence of traffic accidents. Use computer vision technology to sense traffic flow parameters such as road speed and flow in real time, provide real-time road conditions, and combine historical data to predict road network traffi...
