Description

Screen display method, device and system that improves the visibility of images of interest {METHOD, DEVICE AND SYSTEM FOR DISPLAYING SCREEN BY IMPROVING VISIBILITY OF IMAGE OF INTEREST}

The present invention relates to a screen display method, device, and system that improves the visibility of an image of interest, and more specifically, to a screen display method, device, and system that improves the visibility of a region of interest in an image of interest.

A control system is used to monitor multiple locations at once. In general, after equipping multiple locations with imaging devices such as CCTVs, the images transmitted from each CCTV are output on the screen of the control system, enabling managers to monitor multiple locations at once. This control system is widely used in fields such as living safety, social safety, and facility management.

In such control services provided based on multiple videos, a problem often occurs in which the visibility of images of objects included in the videos is low. For example, motion blur may occur when an object is moving, blur may occur when the object is not in focus, or noise may occur in the object due to contamination of the camera CCD (Charge Couple Device). In this case, in order to improve the visibility of the object, techniques are used to process the image of the object in the video more clearly using an image processing algorithm. Based on this, users can monitor the image of the object more accurately.

Meanwhile, most control systems provide monitoring services by processing video in real time, but when the load due to video processing increases, it is difficult to provide monitoring services in real time.

Figure 1 is a diagram schematically showing a screen display system that improves the visibility of an image of interest according to an embodiment of the present invention.

Referring to FIG. 1, the screen display system 100 that improves the visibility of the image of interest according to this embodiment displays the screen by improving the image quality of the object (object of interest) included in the area of interest in the image transmitted to the control system. As a system, when the user of the control system client inputs information about the area of interest in the image, the image quality of the area of interest can be improved and displayed on the screen of the control system client. The screen display system 100 that improves the visibility of images of interest may include a media server 110, a control system client 120, and an image quality improvement server 130. Based on the screen display system 100 with improved visibility of the image of interest shown in FIG. 1, a business model (BM) for displaying the screen with improved visibility of the image of interest can be implemented.

The media server 110 is a device that displays images received from the outside on the screen of the control system client 120. The media server 110 may receive an image from at least one image acquisition device, such as a CCTV, and transmit the at least one received image to the control system client 120. At this time, when transmitting a plurality of images, each image can be distributed so that it is output at a designated location on the screen of the control system client 120. The media server 110 may transmit at least one image transmitted from at least one image acquisition device to the control system client 120 in real time so that the user can monitor the image in real time. The media server 110 may be implemented as an image server, streaming server, IoT server, cloud server, edge server, network server, relay server, gateway, etc. The media server 110 described below is described as a streaming server as an example, but other types of servers described above may also be applied.

The control system client 120 is a device that receives images from the media server 110 and outputs them on the screen. The control system client 120 may be a user terminal or an administrator terminal included in the control system. The control system may be the screen display system 100 with improved visibility described with reference to FIG. 1, or it may be included in the screen display system 100 with improved visibility. That is, the control system and the screen display system 100 with improved visibility may be one integrated system, or the control system may be a part of the screen display system 100 with improved visibility. The control system client 120 may be implemented as a PC, laptop, PDA, smart terminal, mobile terminal, etc. Although the control system client 120 described below is a PC as an example, other types of terminals described above can also be applied.

The image quality improvement server 130 is a device that improves the visibility of the region of interest and can improve the image quality of the region of interest included in the received image using an image quality improvement algorithm. The image quality improvement server 130 may be implemented as an image processing server, streaming server, IoT server, cloud server, edge server, network server, relay server, gateway, etc. The picture quality improvement server 130 described below is an image processing server as an example, but other types of servers described above may also be applied.

The media server 110 may receive information about the area of interest in the image of interest from the control system client 120. Here, the image of interest may be an image being displayed on the screen of the control system client 120. The media server 110 may provide one of the images received from the outside as an image of interest to the control system client 120. These images of interest may be provided at the request of the user of the control system client 120.

The media server 110 may receive information about the area of interest in the previously provided image of interest from the control system client 120. Here, the area of interest may be an area for an object that the user wants to check with higher image quality. For example, while an image of a vehicle is being output to the control system client 120, the user can select the area of the object called the vehicle as the area of interest.

Based on this selection, the media server 110 can receive information about the area of interest selected by the user from the control system client 120. The media server 110 may receive at least one of the location, coordinates, ID, and screen display options of the area of interest selected based on the input of the user of the control system client 120 as information about the area of interest. In other words, information that can identify where the object selected by the user is located in the image of interest can be received as information about the area of interest.

Meanwhile, the control system client 120 may provide a UI that allows the user to input information about the area of interest. The UI may support the function of selecting at least one of the location, coordinates, ID, and screen display options of the area of interest. For example, when a user touches a specific object on the screen, a certain area centered on the touched point is designated as an area of interest, and at least one of the location, coordinates, ID, and screen display options for the designated area of interest is sent to the media. It can be transmitted to the server 110. As another example, when a specific object is selected through an input device (keyboard, mouse, touch pen) provided in the control system client 120, the area corresponding to the object is designated as an area of interest, the location of the designated area of interest, At least one of coordinates, ID, and screen display options may be transmitted to the media server 110. Using the UI, the user can freely input not only the location but also the size of the area of interest. For example, by default, a bounding box whose size can be adjusted is output to the UI, and the user adjusts the position of the bounding box while touching the screen of the control system client 120 and increases or decreases the size of the bounding box with his or her finger. It can be adjusted.

Meanwhile, the media server 110 may transmit the first image corresponding to the image of interest and information on the area of interest received from the control system client 120 to the image quality improvement server 130. The media server 110 stores a plurality of images transmitted from the outside and knows which image was transmitted to the control system client 120. When information about the area of interest is received from the control system client 120, the media server 110 can identify which of the plurality of pre-stored images corresponds to the image of interest. The image identified based on this process is called the first image. That is, the image of interest being output to the control system client 120 and the first image stored in the media server 110 may be the same image. The media server 110 may transmit information about the first image and the region of interest to the image quality improvement server.

Meanwhile, in the case of a control system that provides a service for conventional real-time monitoring, when images are transmitted and received between devices to maintain real-time service, the image is resized to prevent communication latency from occurring to increase communication speed. must be maintained In this way, image quality may deteriorate during the process of resizing the image. In order to improve this problem, instead of directly performing an image quality improvement operation, the media server 110 reduces the size (capacity) of the first image to prevent image quality deterioration and provides the image quality improvement server 130 with information about the region of interest. can be transmitted to. For example, the media server 110 may crop the region of interest from the stored first image based on information about the region of interest and transmit the cropped image of the region of interest to the image quality improvement server 130. In other words, while maintaining the image quality of the image to be transmitted, only the area of interest that requires image quality improvement can be cropped and transmitted. At this time, the cropped first image may be transmitted to the image quality improvement server 130 as is, or may be enlarged to the size of the image of interest and transmitted.

The image quality improvement server 130 may perform an image quality improvement operation on the first image. When the image quality improvement server 130 receives information about the first image and the region of interest together, the image quality improvement server 130 may identify the region of interest within the first image and then perform an image quality improvement operation on the region of interest. Of course, if the received first image is a cropped image, the image quality improvement operation may be performed without identifying the region of interest.

The image quality improvement server 130 may improve the image quality of the region of interest in the first image based on various image quality improvement algorithms. For example, the image quality of the region of interest can be improved based on at least one of a super resolution algorithm, a denoising algorithm, and a deblurring task algorithm. The image quality improvement server 130 improves the area of interest (image of the object) to clearer image quality using a traditional rule-based approach algorithm or a data-driven approach algorithm. The action can be performed.

The image quality improvement server 130 may generate a second image with improved image quality of the region of interest based on performing this image quality improvement operation. The image quality improvement server 130 may generate a second image based on the screen display option included in the information about the region of interest. For example, an image of a region of interest with improved image quality may be inserted into the same location as the region of interest in the first image to create a second image. As another example, an image of a region of interest with improved image quality may be inserted at the same location as the region of interest in the first image, but an image with the remaining region blurred may be created as a second image. As another example, an image from which a region of interest with improved image quality is extracted can be generated as a second image. That is, the image quality improvement server 130 may perform post-processing on the image of the region of interest with improved image quality in a form that matches the screen display options entered by the user.

Meanwhile, data communication methods for transmitting the result (second image) of performing an image quality improvement operation in the image quality improvement server 130 include RTP (Real Time Transport Protocol), RTSP (Real Time Streaming Protocol), and HLS (HTTP Live Streaming). ), it may be a method suitable for real-time streaming. Likewise, the image transmission method of the media server 110 may also be one of RTP, RTSP, and HLS.

Figure 2 is a diagram showing the UI of the control system client.

Referring to FIG. 2, the control system client may be the same device as the control system client 120 described with reference to FIG. 1. A UI for user input may be displayed on the screen of the control system client 120. This UI can be implemented as a Windows app, Linux app, mobile app, website, etc.

Images of interest received from the media server 110 may be displayed on the screen of the control system client 120. In addition, a list of functions needed by the user in a control situation can also be output. For example, in area 1 of FIG. 2, an image of interest may be displayed, and in area 2, a screenshot and a list of functions for specifying an object of interest may be displayed. The user can use the function displayed in area 2 to select the area of a specific object for which image quality is desired to be improved on the image of interest being displayed on the screen as the area of interest. That is, an area of interest with a vehicle as an object of interest, such as area 3, may be selected. The user can complete the selection of the area of interest by selecting the area of interest and then touching or pressing OK (area 4).

Meanwhile, users can set screen display options in the form they want. For example, when area 4 is selected and the area of interest is selected, area 5 is displayed in a pop-up form or in a separate area on the screen, allowing the user to select the desired screen display option from the list displayed in area 5. You can do it. When a user selects a specific screen display option and then selects a starting area, the control system client 120 can transmit information about the area of interest to the media server 110.

Figure 3 is a diagram showing images output according to screen display options.

Referring to FIG. 3, the image quality improvement server 130 may generate a second image based on the screen display option selected by the user. For example, if the user selects display method 1, the image quality improvement server 130 inserts the image of the region of interest with improved image quality at the same location as the region of interest in the first image, but blurs the remaining region to create the second image. It can be created with As another example, if the user selects display method 2, the image quality improvement server 130 may insert the image of the region of interest with improved image quality into the same position as the region of interest on the first image to create a second image. As another example, if the user selects display method 3, the image quality improvement server 130 may extract the region of interest with improved image quality and create a second image. The extracted image may have the region of interest extracted at a larger size than other display methods, as shown in Figure 3, or only the region of interest may be extracted after removing the remaining background.

Figure 4 is a flowchart of a screen display method with improved visibility of an image of interest according to an embodiment of the present invention.

Referring to FIG. 4, the screen display method 400 with improved visibility of the image of interest includes steps S410 to S440. The screen display method 400 that improves the visibility of the image of interest according to this embodiment is explained through the operation of the media server 110 described with reference to FIG. 1 .

In step S410, the media server 110 receives information about the region of interest in the image of interest from the control system client 120. The media server 110 has transmitted the image of interest to the control system client 120 before performing step S410. The media server 110 may receive information about the area of interest input from the user of the control system client 120.

In step S420, the media server 110 transmits the first image corresponding to the image of interest and information about the region of interest to the image quality improvement server 130. Since the media server 110 knows which image of interest is transmitted to the control system client 120, it can identify which image among the plurality of pre-stored images is the first image corresponding to the image of interest. The media server 110 may transmit the identified first image and information about the region of interest received from the control system client 120 to the image quality improvement server 130.

In step S430, the media server 110 receives a second image with improved image quality of the region of interest from the image quality improvement server 130. The second image refers to an image generated by the picture quality improvement server 130 based on the picture quality improvement algorithm. The second image may be an image of a region of interest with improved image quality inserted at the same location as the region of interest on the first image, or an image of a region of interest with improved image quality may be inserted at the same location as the region of interest on the first image. , The remaining area may be blurred, or it may be an image from which a region of interest with improved image quality has been extracted. The image quality improvement server 130 may generate this second image based on the screen display option included in the information about the region of interest.

In step S430, the media server 110 transmits the received second image to the control system client 120. Since the media server 110 has processed the second image through the picture quality improvement server 130, the second image can be transmitted to the control system client without additional communication latency.

Figure 5 is a flowchart showing the operation of the picture quality improvement server.

Referring to FIG. 5, steps S510 to S550 are explained as operations by the image quality improvement server 130 described with reference to FIG. 1. If step S420 described above with reference to FIG. 4 is performed through the media server 110, the picture quality improvement server 130 may perform steps S510 to S540.

In step S510, the image quality improvement server 130 receives information about the first image and the region of interest. The first image that the picture quality improvement server 130 receives may be an original image or an image cropped from a media server. The image quality improvement server 130 receives information about the region of interest along with the first image.

In step S520, the image quality improvement server 130 extracts an image of an object of interest within the area of interest. The image quality improvement server 130 may identify where an object for image quality improvement is located in the first image based on information about the region of interest. For example, the coordinates of an object included in the first image may be identified based on the coordinates of the region of interest. The image quality improvement server 130 can extract an image of an object (object of interest). If a cropped image is received from the media server 110, since it already corresponds to an image of an object, step S520 can be omitted.

In step S530, the image quality improvement server 130 performs an operation to improve the image quality of the object of interest image. The image quality improvement server 130 can improve the image quality of the object of interest image using image quality improvement algorithms such as a super resolution algorithm, denoising algorithm, and deblurring task algorithm.

In step S540, the image quality improvement server 130 post-processes the image of the object of interest based on the screen display options. Information about the area of interest may include screen display options entered by the user. The image quality improvement server 130 can post-process the image of the object of interest with improved image quality in a format desired by the user based on these screen display options. For example, an image of a region of interest with improved image quality may be inserted at the same location as the region of interest on the first image. As another example, an image of a region of interest with improved image quality may be inserted at the same location as the region of interest in the first image, but the remaining region may be treated as a blur. As another example, a region of interest with improved image quality can be extracted.
