Deep-convolution-neural-network-based method for detecting illegal parking and converse running of vehicles

The invention relates to a deep-convolution-neural-network-based method for detecting illegal parking and converse running of vehicles. A mobile terminal detection point is used as a road camera. The mobile terminal detection point obtains image information by the camera and depth learning is introduced into road event identification and improvement is also carried out, so that the accuracy of road event identification can be improved obviously. According to the method provided by the invention, a convolution neural network is used for analyzing an obtained image; a pavement ROI region is divided into a plurality of networks; a pavement-non-pavement identification model is constructed; and reverse identification of illegal parking and converse running of vehicles at highways is realized by using a non-pavement grid. The method is applied to non-real-time tasks like pavement illegal parking detection and converse running detection of vehicles. With full utilization of advantages and characteristics of the mobile internet network, high-coverage pavement event detection including illegal parking and converse running of vehicles is realized with low cost.

Micro seismic event recognition method based on morphological filtering

The invention provides a micro seismic event recognition method based on morphological filtering. The method comprises the steps of conducting spectral analysis on micro seismic data; rectifying a demodulator used for receiving micro seismic signals; selecting structural elements, combining opening operation and closing operation to form a morphological noise filter, and conducting the morphological filtering on the micro seismic data going through spectral analysis; calculating the energy ratio of a long-time window and a short-time window according to the data going through the morphological filtering, and comparing the energy ratio and triggering threshold to identify whether the demodulator has micro seismic events; and conducting microseism pickup according to the micro seismic events. According to the method, the signal to noise ratio of the data can be improved through preprocessing and further filtering treatment; the micro seismic events can be detected quickly and accurately by utilization of the energy ratio method, the fluctuation type of the micro seismic events can be identified through polarization analysis, and first arrival can be picked up accurately by utilization of self-adaptation threshold and the long-time and short-time window energy ratio method.

Method for detecting, tracking and identifying object abandoning/stealing event

InactiveCN101727672AFull motion goal stateAccurate motion target stateImage analysisCharacter and pattern recognitionMorphological processingInter frame
The invention discloses a method for detecting, tracking and identifying an object abandoning / stealing event, which comprises the following steps of: 1) the detection of a moving object, namely, establishing an adaptive background model, extracting the moving object by utilizing a background difference and performing morphological processing and shadow processing to obtain a more complete and more accurate state of the moving object; 2) the tracking of the moving object, namely, realizing the inter-frame matching of the moving object through a recursion process of estimating, observing and correcting the state of the moving object, and tracking a moving track of the moving object; and 3) event identification, namely, giving a clear definition to the object abandoning / stealing event, judging the occurrence of the event according to the characteristics and the moving track of the moving object, if the event occurs, distinguishing an object abandoning event from an object stealing event, capturing evidence pictures for the identified abandoning and stealing events and giving an audible alarm.
