Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings.

[0048] like figure 1 Shown is a flow chart of a method for detecting and identifying highway pavement defects based on a wireless network video sensor, which specifically includes the following steps:

[0049] (1) Collect video images of highway road surface diseases and locate the location of the diseases, and transmit them to the traffic information processing center through the wireless network for storage and pre-detection, specifically including the following steps:

[0050](1-1) The road surface video image is taken by the vehicle-mounted high-speed wireless network camera, and the collected video image should cover the entire single-lane driving; while the road surface video image is obtained, the GPS records the road surface geographic location information corresponding to the current image frame ;

[0051] (1-2) Real-time transmission of video images to the ...

Abstract

The invention discloses a pavement disease detecting and recognizing method based on a wireless online video sensor, which includes: acquiring an expressway pavement disease video image and locating the disease position; preprocessing the video image and extracting a disease target area; and extracting expressway pavement disease texture features by means of HGM (hollow glass microsphere) multi-wavelet transform. Using the pavement disease detecting and recognizing method based on the wireless online video sensor can detect primary conditions of pavement diseases in real time, track the development situations of the diseases and analyze development trends of the pavement diseases, and the method is high in instantaneity and detection efficiency. In addition, applying the method to expressway pavement disease detection can save expressway maintenance cost, guarantee traffic safety and prolong service life of roads.

Description

technical field [0001] The invention relates to pattern recognition and traffic safety research technology, in particular to a detection and recognition technology of expressway road surface disease based on a wireless network video sensor. Background technique [0002] The rapid development of wireless video transmission technology, computer high-performance processors, large-capacity storage systems, image processing technology and pattern recognition technology makes it possible to automatically detect and identify highway road surface diseases based on wireless video sensors and image processing technology. By installing wireless network road surface video acquisition equipment and GPS system on the measurement vehicle, real-time collection of road surface condition information and location information, the collected data is transmitted to the information processing center through wireless communication technology, and image preprocessing and road surface disease characte...
