Description

[0001] The present invention relates to an intelligent multifunctional video surveillance system,

The present invention can be applied to a vehicle equipped with at least one camera on an intersection and collecting images photographed therefrom, a pedestrian using a crosswalk as well as a vehicle stopped on the basis of a collected image and a status signal of a vehicle and a pedestrian signal The present invention also relates to an intelligent multifunctional video surveillance system for selectively interrupting broadcasting or interrupting a vehicle,

 In general, violation of traffic regulations in driving a vehicle is a dangerous act that can take away not only your life but also the life of others. Even though the driver must comply with the traffic regulations for the safety of himself and others There are few cases of violations of traffic regulations.

In the case of vehicles that violate these traffic regulations, the driver is required to ask for the judicial responsibility only if the violation of the traffic regulations has been enforced so far, and if the traffic violation is not enforced, the driver can not be held responsible.

Therefore, in the country, there are various measures to control vehicles that violate traffic regulations.

Most road traffic accidents in Korea occur at crossings. Especially, when red traffic lights are lit, ignorance of traffic accidents causes damage to people and loss of vehicles.

In the past, despite the red traffic lights on the road with the traffic light, there is a limit to the police catching the vehicle that rushes.

FIG. 3 is a block diagram illustrating a configuration of an intermittent server according to an embodiment of the present invention. FIGS. 4A to 4B are views illustrating an intermittent vehicle interruption process of an intermittent server, which is one embodiment of the present invention.

The intermittent server 300 according to an embodiment of the present invention may include an intercept target designating part 310, a camera control part 320 and a vehicle number recognizing part 330 as shown in FIG.

As described above, the interception target designating section 310 can detect various traffic misconducts such as a violation of a signal instruction on an intersection, a violation of a stop line, a violation of a traffic method, etc. from a photographed image interlocked with the display state of the vehicle or pedestrian signal lamps 10, And can designate a vehicle to be controlled for a suspected violation vehicle.

For example, the interception target designation unit 310 may control the signal designation violation of the intersection and designate the vehicle to be interrupted.

As shown in FIG. 4A, the interception target designation unit 310 can set each stop line area a for each lane line, and the state of the vehicle signal lamp 10 is set to the image photographed from the lane It is possible to designate the vehicle being stopped by invading the stop line area (a) as the first intercept target vehicle (31).

As another example, the interception target designation unit 310 sets the crosswalk area b for each lane, as shown in FIG. 4B. In the case of the image photographed from the lane where the state of the pedestrian signal light 20 is the progress signal It is possible to designate the stopped vehicle as the second intercept target vehicle 32 by invading the set transverse coverage area b.

The traffic light control unit 310 may analyze the images photographed for each lane to determine the congestion state according to the traffic lane, set an entry area c for an intersection, When the lane in which the state of the lane marking is the progress signal is in the stagnation state, the vehicle entering the intersection area c set in the image photographed from the lane can be designated as the third interception target vehicle 33.

The intelligent multifunctional video surveillance system of the present invention may include a speaker installed in proximity to the vehicle signal lamp 10 or the pedestrian signal lamp 20 although not shown in the figure, It is possible to generate sound signals for vehicle guidance and warning announcement broadcasts to vehicles 31 to 33 and broadcast them through the speakers.

In addition, as one embodiment, the air traffic control server 300 can monitor not only a vehicle to be controlled but also a pedestrian walking on a pedestrian crossing in real time and output a guidance and warning announcement broadcast.

That is, the traffic jam server 200 sets the crosswalk area c for each traffic lane and transmits the transit coverage area c set for the image photographed from the traffic lane, If it detects that the pedestrian is walking, it can generate an acoustic signal to guide the pedestrian broadcasting and output it to a speaker installed in proximity to the pedestrian signal lamp 20.

On the other hand, the car number recognizing unit 330 can recognize and output the car number for the vehicle designated as the subject vehicle 31 to 33 during the traffic interrupting process of the intersection.

In addition, the camera controller 320 generates a control signal to magnify the face of the driver driving the vehicles 31 to 33 designated as the vehicle to be controlled in the course of the traffic interrupting process of the intersection according to the embodiment, 200).

The camera 210 of the image preparation unit 200 may perform a zoom function according to a control signal transmitted from the camera control unit 320 and may be equipped with an infrared filter to improve the discrimination of face information in a bad weather environment such as at night So that an infrared-ray-sight image can be selectively collected.

Here, the infrared filter according to an embodiment of the present invention may be configured such that an infrared transmitting coating layer is coated on one side or both sides of a glass lens in the construction of the filter so that only the infrared region is transmitted.

The infrared transmitting coating layer may be formed on a glass lens by various methods such as spin coating, deep coating, spray coating, offset printing, coating with a brush or sponge, The coating layer is formed by heating at a temperature of 150 to 250 ° C. In this thermal curing process, micro-cracks are generated in the coating layer and the infrared ray transmission effect is inhibited. In addition, The condensation obstructs the transmission effect of the infrared rays as well as the blocking of the shielded rays, thereby preventing the collection of the discriminative images. Accordingly, the present invention provides the following embodiments.

First, the infrared ray filter is coated with an infrared ray transmitting coating layer on one side or both sides of a glass lens, wherein the infrared ray transmitting coating layer comprises 5 to 10 parts by weight of cellulose acetate, 1 to 5 parts by weight of aluminum hydroxide, To 5 parts by weight of an infrared ray transmitting powder is dispersed in a solvent and is formed by thermal curing at 150 to 250 ° C. Here, it is appropriate to use water or an alcohol solvent as the solvent.

The carbon black is added as a blocking material for a visible light region other than infrared rays because the visible light absorbance is significantly higher than the infrared absorbance.

However, carbon black has a problem causing generation of haze, and there is a problem that the generation of condensation on the surface may occur due to the occurrence of such haze. Therefore, in the present invention, cellulose acetate is added together with carbon black to hydrophilize the surface of the coating layer to control the generation of condensation.

The aluminum hydroxide absorbs heat generated during the heat curing process and is decomposed into aluminum trioxide and water. That is, it is possible to control the temperature crack by reducing the hardening heat. In addition, when water is used as a solvent, water evaporates in the course of thermosetting and cracks are generated by the evaporation of the water. In addition to absorbing heat by adding aluminum hydroxide, water is decomposed into aluminum trioxide and water, Function.

In addition, it is necessary to control the autogenous shrinkage by preventing the surplus water from being rapidly evaporated and dried in the thermosetting process, and it is necessary to control the crack due to plastic shrinkage due to drying of the surface of the coating layer by such evaporation. Accordingly, in the present invention, sulfur oxide is further added, and sulfur iron oxide is used to control the autogenous shrinkage of the paste by delaying the reaction rate to induce the continuous reaction.

That is, the addition of the sulfur iron oxide added for the purpose of delaying the reaction can significantly suppress the shrinkage of the paste. This is because sulfur iron oxide generates acicular crystals in the heat curing process and induces the paste to a dense structure by the growth pressure of the acicular crystals. That is, as many fine needle crystals are developed, the expansion pressure can be obtained, thereby reducing the effect of shrinkage, thereby controlling microcracks due to self-shrinkage.

On the other hand, it is preferable to clean the surface of the glass lens before applying the infrared ray-permeable coating layer to the glass lens. By this cleaning, adhesion force and smoothness of the glass lens and the coating layer can be improved.

The glass lens contains a small amount of metal components such as silicon, iron, and copper, and is subjected to surface treatment by etching or the like for the smoothness of the glass lens. In general, since 3 to 20% sodium hydroxide is generally used for etching, the small amount of metal components such as silicon and iron is not dissolved in the alkali aqueous solution and remains on the surface of the material in a state of being protruded by the alkali aqueous solution, It acts as a factor for lowering the adhesion and smoothness.

In order to remove such protruding foreign matter, a concentrated aqueous solution of nitric acid is conventionally used, and a mixed aqueous solution is added by adding hydrofluoric acid to remove foreign substances by the silicon component which is not dissolved in the high concentration nitric acid aqueous solution.

However, there is a problem in that a large amount of nitric acid (NOx) gas is discharged by the use of nitric acid, the hydrofluoric acid gas is discharged by the use of hydrofluoric acid, and nitric acid nitrogen of high concentration occurs in the wastewater, there was.

Accordingly, in the present invention, as a treatment liquid for removing foreign matters remaining on the surface during the surface treatment of the glass lens, 40 to 50 parts by weight of sulfuric acid, 3 to 6 parts by weight of ascorbic acid, 1 to 3 parts by weight of dinonylnaphthylsulfonic acid ammonium salt And the remaining part is a water treatment liquid.

If the blend ratio exceeds 50 parts by weight, the glass lens base material component tends to be over-etched, and if it is less than 40 parts by weight, the foreign matter removal efficiency is insufficient. As well.

In addition, ascorbic acid and dinonylnaphthylsulfonic acid ammonium salts are further added to the above-mentioned range in the treatment liquid.

When treated with a strong acid such as sulfuric acid, the surface becomes positively charged when the pH of the cleaning solution is lower than the PZC of the metal oxide such as iron oxide or manganese oxide. When the pH is lower, the charge amount is increased. As the pH of the treatment solution is lowered, the eluted anions are not dissolved and re-adsorbed to the residual iron oxide, manganese oxide, and the like, in the various anions eluted by the acid.

In addition, when a treatment solution of strong acid is used, the solubility of metal oxides such as iron oxide and manganese oxide is increased, but the remaining metal oxides such as iron oxide and manganese oxide that do not dissolve are formed as the pH of the washing solution is low and act as a very strong adsorbent . And the anions eluted therefrom are strongly adsorbed to metal oxides such as iron oxide and manganese oxide, resulting in deterioration of the foreign matter removal efficiency.

Accordingly, in the present invention, the pH is lowered by treatment with sulfuric acid to remove foreign substances, and addition of the ascorbic acid prevents the eluted anions from being oxidized, thereby controlling the reduction of foreign matter removal efficiency by re-adsorption.

In addition, in the present invention, dinonylnaphthylsulfonic acid ammonium salt is further included so that the treatment liquid contains the ascorbic acid. The reason why dinonylnaphthylsulfonic acid ammonium salt is further included in this way is to prevent oxidation of the ions eluted by the ascorbic acid, and at the same time to prevent adsorption by water absorption by dinonylnaphthylsulfonic acid ammonium salt, It is possible to control the generation of the adsorbent which is not treated by the acid.

Meanwhile, the car number recognition unit 330 of the analysis server 300 extracts the license plate area using the learning data generated through the learning algorithm in recognizing the car number, and recognizes the car number from the license plate area have.

Here, the vehicle number recognizing unit 330 may capture an image of a front side of the vehicle and designate the captured image as an analysis target image prior to the car number recognition process. In the analysis target image, a noise removing process, And so on, thereby obtaining a more clear captured image.

The car number recognizing unit 330 includes a license plate detecting database 333, a car number detecting database 334, a license plate area extracting unit 331 and a car number extracting unit 332 as shown in Fig. 3 .

The license plate detection database 333 may store a plurality of first learning data extracted through MB-LBP (Multi-scale Block-Local Binary Pattern) cascade machine learning.

The car number detection database 334 may store a plurality of second learning data extracted through MCT (Modified Census Transform) algorithm learning.

The license plate region extracting unit 331 compares and analyzes the first learning data of the license plate detection database with the analysis target image captured in the photographed images of the vehicles 31 to 33 and extracts license plate regions for the vehicle to be controlled can do.

The vehicle number extracting unit 332 compares and analyzes the license plate area of the vehicles 31 to 33 extracted by the license plate area extracting unit 331 with the second learning data and outputs the comparison result to the control target vehicles 31 to 33 It is possible to extract and output the vehicle number.

5A to 5E are diagrams for explaining a vehicle number recognition process of the intermittent server which is a constitution of the present invention.

5A, a LBP (Local Binary Pattern) is calculated as a value calculated for all the pixels of the image, and the LBP Is an index value obtained by coding the relative brightness change of the surrounding 3x3 region in binary. In other words, if a pixel is brighter than the center pixel, it is encoded as 1, and when it is dark, binary values can be used as an index for the local texture.

As shown in FIG. 5B, the histogram is calculated for the index values calculated for the respective pixels, and then the histogram is divided into cells of a predetermined size based on the texture for the corresponding image region, and LBP A histogram for the histogram is obtained, and a vector obtained by connecting the histograms in a line is utilized as the final feature data, i.e., the first learning data.

In other words, large scale texture information can be extracted by using LBP in block units instead of pixels, and MB-LBP (Multi-scale Block-Local Binary Pattern) can be calculated for different scales and image positions. It is possible to extract various features for the object of

Through this process, we can extract a myriad of LBP features for one object. We can use AdaBoost learning algorithm to automatically select LBP features with high discrimination among them.

Also, in order to detect quickly, the license plate area image is normalized to 458 x 16, so that the license plate area can be extracted to a smaller license plate area.

The car number extracting unit 332 can extract and recognize an accurate car number by comparing it with data generated through learning using a MCT (Modified Census Transform) algorithm in the license plate area extracted through the process described above.

MCT is currently the most popular method in the field of Face Detection and has excellent detection performance.
