Description

Technical Field

[0001] The present invention relates to the field of traffic management, and more specifically, to a real-time big data identification system for target contact status. Background Art

[0002] The emergency lane of an expressway refers to a road surface that is adjacent to the right-hand road lane, has a width of more than 3 meters, including the hard shoulder, and an effective length of greater than or equal to 30 meters, and can meet the parking needs of motor vehicles. In an emergency, vehicles can drive or park on the emergency lane.

[0003] In the event of traffic congestion ahead, it is prohibited to park or queue in the emergency lane. When the driver's vehicle breaks down and needs to stop to repair it, he should not immediately turn on the hazard warning lights and move the broken vehicle to a place where it will not hinder traffic, so as to avoid a secondary accident.

[0004] However, due to the high speed of vehicles on highways, it is difficult to accurately identify the illegal behavior of temporarily occupying the emergency lane for a short time, which provides space and time for safety accidents on highways. Summary of the invention

[0005] In order to solve the technical problems in the related fields, the present invention provides a real-time big data identification system for target contact status, which can introduce a preview processing device for performing visual recognition processing on the preview monitoring picture of the first resolution of the highway road surface to determine whether there is a vehicle, and when it is determined that there is a vehicle, drive the road surface capture mechanism to convert to the second resolution to perform road surface environment capture operation on the highway road surface to obtain a real-shot monitoring picture of the second resolution, thereby taking into account the computing power and monitoring effect of the monitoring system.

[0006] The present invention needs to have at least the following important invention points:

[0007] First, the depth of field values ​​corresponding to the pixel points of the image blocks of the emergency lane in the data-sharpened image obtained after the customized sharpening process are obtained, and the depth of field values ​​corresponding to the pixel points of the image blocks of the vehicle in the data-sharpened image are obtained. When the depth of field value corresponding to a certain pixel point corresponding to the emergency lane is the same as the depth of field value corresponding to a certain pixel point corresponding to the vehicle and the positions of the two pixels in the data-sharpened image are the same, it is determined that the emergency lane and the vehicle are in contact and a vehicle violation detection signal is issued. Otherwise, it is determined that the emergency lane and the vehicle are separated, thereby achieving high-precision and real-time identification of the driving behavior of the vehicle illegally driving on the emergency lane;

[0008] Second: based on the brightness imaging characteristics corresponding to the emergency lane, the image blocks of the emergency lane in the data-sharpened image are identified, and based on the shape imaging characteristics corresponding to the vehicle, the image blocks of the vehicle in the data-sharpened image are identified, thereby providing key information for the subsequent analysis of the relative status of the emergency lane and the vehicle;

[0009] Third: a preview processing device is introduced to perform visual recognition processing on the preview monitoring picture of the highway road surface with a first resolution to determine whether there is a vehicle. When it is determined that there is a vehicle, the road surface capture mechanism is driven to convert the resolution to the second resolution to perform road surface environment capture operation on the highway road surface to obtain a real-shot monitoring picture with a second resolution, thereby taking into account both the computational complexity and monitoring effect of the monitoring system.

[0010] According to the present invention, a target contact status real-time big data identification system is provided, the system comprising:

[0011] A preview processing device is used to perform visual recognition processing on the preview monitoring picture of the highway road surface at the first resolution to determine whether there is a vehicle, and when it is determined that there is a vehicle, drive the road surface capture mechanism to convert to the second resolution to perform a road surface environment capture operation on the highway road surface to obtain a real-shot monitoring picture of the second resolution;

[0013] A guided filtering device, connected to the road surface capturing mechanism, is used to perform guided filtering processing on the received real-shot monitoring picture of the second resolution to obtain and output a corresponding guided filtering image;

[0014] a directional filtering device, connected to the guided filtering device, for performing directional filtering processing on the received guided filtering image to obtain and output a corresponding directional filtering image;

[0015] A data sharpening device, connected to the directional filtering device, for performing a spatial differential sharpening process on the received directional filtered image to obtain and output a corresponding data sharpened image;

[0016] a contact judgment device connected to the data sharpening device, and used to receive the data sharpened image, obtain the depth of field values ​​corresponding to the pixel points of the image block of the emergency lane in the data sharpened image, and obtain the depth of field values ​​corresponding to the pixel points of the image block of the vehicle in the data sharpened image, and when the depth of field value corresponding to a certain pixel point corresponding to the emergency lane is the same as the depth of field value corresponding to a certain pixel point corresponding to the vehicle and the positions of the two pixel points in the data sharpened image are the same, it is judged that the emergency lane and the vehicle are in contact and a vehicle violation detection signal is issued; otherwise, it is judged that the emergency lane and the vehicle are separated;

[0017] Wherein, the contact judgment device identifies the image block of the emergency lane in the data sharpened image based on the imaging characteristics corresponding to the emergency lane, and identifies the image block of the vehicle in the data sharpened image based on the imaging characteristics corresponding to the vehicle;

[0018] Among them, visual recognition processing is performed on the preview monitoring picture of the highway road surface with a first resolution to determine whether there is a vehicle, and when it is determined that there is a vehicle, the road surface capture mechanism is driven to convert to a second resolution to perform a road surface environment capture operation on the highway road surface to obtain a real-shot monitoring picture with a second resolution, including: visual recognition processing is performed on the preview monitoring picture of the highway road surface with a first resolution to determine whether there is a vehicle based on the vehicle's appearance imaging characteristics.

[0019] The target contact status real-time big data identification system of the present invention operates intelligently and has a certain monitoring accuracy. Since a preview processing device can be introduced to adaptively transform the resolution of the preview monitoring screen of the highway road surface, a targeted visual analysis mechanism is used to perform high-precision identification of violations of short-term and temporary occupation of emergency lanes on the highway, thereby effectively maintaining the safety of the highway.
