Figure 10 is a diagram showing an example of an image correction filter according to the present invention, and Figure 11 shows an HSV graph according to the present invention.

According to Figure 10, the types and functions of filters are shown. In other words, the CNN algorithm may be a learning algorithm that uses multiple layers. In addition, the CNN algorithm can automatically learn filters that maximize image classification accuracy, and by adding new layers called convolutional layers and polling layers before the fully connected layer, the filtered image is obtained after applying the filtering technique to the original image. A classification operation can be performed on . The CNN algorithm is configured to apply a filtering technique to the original image by adding a new layer called a convolutional layer and a pooling layer before the fully-connected layer, and then perform a classification operation on the filtered image. You can.

At this time, the calculation formula for the image filter using the CNN algorithm is as shown in Equation 1 below.

[Equation 1]

(step,

: filter,

: image,

: Height of filter (number of rows),

: Width (number of columns) of the filter. )

Preferably, the calculation equation for the image filter using the CNN algorithm is as shown in Equation 2 below.

(step,

: Pixel of the ith row and jth column of the filtered image expressed as a matrix,

: Application filter

: image,

: height of application filter (number of rows),

: Width (number of columns) of the application filter.)

Preferably, is an application filter that learns image data containing vehicle and parking space identification information and may be a filter applied to the image data to recognize the vehicle and parking space identification information included in the image data. In particular, vehicle and parking space identification information may be classified based on differences in shape and color, so an application filter may be necessary to effectively recognize shape and color. To meet these needs, application filters Can be calculated by Equation 3 below.

H(Hue, 0~360°) can mean hue, S(Saturation, 0~100%) can mean saturation, and V(Value, 0~100%) can mean brightness. . Hue, saturation, and brightness values can be referred to as HSV values, which can be easily extracted using graphic tools such as Adobe Illustrator CC 2019.

The HSV average value according to the present invention can be obtained through the HSV three-dimensional coordinates of FIG. 11. That is, the HSV average value according to the present invention can be calculated based on the HSV value obtained through a graphic tool. The distance value of the HSV coordinates measured with the origin coordinates on the HSV three-dimensional coordinates as the reference point can constitute the above-described HSV average value. That is, the image according to the present invention includes images of vehicle and parking space identification information, and the HSV color coordinates of the image may be distributed in a certain area among HSV three-dimensional coordinates. Therefore, the HSV average value according to the present invention may mean the distance value from the origin coordinate calculated based on the average coordinate using the average of the HSV coordinates for the color of a certain area.

[Experimental example]

When applying the application filter F' of the present invention to the image data according to the present invention, the recognition accuracy of parking space occupancy and parking space identification information is as follows. The table below is a numerical representation of the accuracy of recognition results based on whether or not filters are applied, based on requests from 10 experts in the relevant technology field.

No filter applied filter apply filter apply Average Accuracy (Score) 75 90 97

Table 1 above shows the accuracy scores evaluated by experts for each case. This experimental example investigates the accuracy of a learning module previously learned using the same big data, depending on whether or not a filter is applied.

In addition, this experimental example was tested with video data including images of 120 different parking spaces, and the accuracy of recognition of the vehicle occupancy and identification number of the parking space included in the video data was tested for the recognition results. This was a survey from 10 experts.

As can be seen in Table 1, when no filter was applied, there was a possibility that an error would occur in image recognition, so the accuracy was evaluated to be relatively low. In comparison, the accuracy was somewhat higher when the general CNN filter F was applied, but it was confirmed that the accuracy was significantly improved when the applied filter F' was applied.
