1 is a conceptual diagram illustrating a method and apparatus for matching roommates sharing real estate according to an exemplary embodiment.

Referring to FIG. 1, an apparatus for matching roommates (100, which may be abbreviated hereinafter as a roommate matching device) is a real estate registration terminal for registering real estate to be used with two or more roommates in the roommate matching device 100 ( 300) and the user terminal 200 that intends to use (or lease) at least one of a plurality of registered real estate registered in the roommate matching device 100 may operate.

The real estate registration terminal 300 may register at least one real estate that two or more roommates can use together with the roommate matching device 100. The real estate registration terminal 300 may be a terminal of a real estate owner who allows sharing of real estate, but as a user terminal of a candidate roommate who wants to obtain a roommate, the real estate registration terminal 300 may be implemented in an integrated form with the user terminal 200 described above. For example, the real estate registration terminal 300 may transmit real estate information including the address, area, and facilities of the real estate to be registered to the roommate matching device 100.

The roommate matching device 100 stores the real estate information received from the real estate registration terminal 300 in the storage device 160, and stores the real estate information stored in the storage device 160 in a real estate application to be driven in the user terminal 200. Register and distribute real estate applications through at least one distribution server. Facilities may include toilets, desks, TVs, refrigerators, conference rooms, projectors, etc. that roommates occupying the real estate can use together. In this case, the real estate information may further include a floor plan of the real estate to be registered.

In addition, the roommate matching device 100 may pre-process real estate information and store it in the storage device 160. For example, the preprocessing may include a procedure of converting a data format of real estate information into a preset data format.

The user terminal 200 is a terminal of a user who wants to use registered real estate registered in the roommate matching device 100, and includes a processor that runs a real estate application directly or indirectly distributed by the roommate matching device 100. Can include. Hereinafter, the operation of the user terminal 200 may be interpreted as an operation of a processor that drives a real estate application.

The user terminal 200 may transmit user information to the roommate matching device 100. Here, the user information may include a user's name, age, smoking status, residential purpose (study, sleep, commuting, etc.), an address of a current residence, etc. of a user who intends to use the registered real estate.

The roommate matching device 100 may store user information received from the user terminal 200 in the storage device 160. In this case, a series of procedures in which the user terminal 200 transmits user information and the roommate matching apparatus 100 matches and stores the user information may be a user subscription procedure. For example, the user terminal 200 transmits a subscription request message including user information to the roommate matching device 100, and the roommate matching device 100 verifies the user information, and based on the verification result, the user terminal ( 200) can transmit a subscription approval message.

After the user registration procedure, the roommate matching device 100 may transmit a list including a plurality of registered real estate collected in the storage device 160 to the user terminal 200. The user terminal 200 may receive one of the registered real estate included in the list from the user and transmit selection information indicating one of the registered real estate to the roommate matching apparatus 100.

In this case, the roommate matching device 100 may display at least one room image corresponding to at least one room, a kitchen, and a bathroom constituting the registered real estate indicated by the selection information. ). Here, the room image is an image taken for at least one of at least one room, a kitchen, and a bathroom in the real estate where the user who wants to use the real estate currently resides, and the user currently It can be a data that can indirectly check the real estate usage status of the real estate you live in. A room image captured by the user of the user terminal 200 for one of the rooms of the real estate in which he resides may correspond to one of the rooms of the registered real estate indicated by the selection information, and the user of the user terminal 200 The room image photographed for the kitchen of the real estate in residence can correspond to the kitchen of the registered real estate indicated by the selection information, and the room image photographed by the user of the user terminal 200 for the bathroom of the real estate in which he resides It can correspond to the toilet of the registered real estate indicated by the selection information.

For example, the roommate matching device 100 may receive three room images corresponding to one of the rooms constituting the registered real estate, a kitchen and a toilet, from the user terminal 200. As more room images are received from the user terminal 200, the roommate matching apparatus 100 may provide a more accurate recommended roommate to the user terminal 200.

The roommate matching apparatus 100 may obtain user information and room images for a plurality of candidate roommates corresponding to the registered real estate indicated by the selection information. For example, the roommate matching device 100 collects user information and selection information targeting a plurality of candidate roommates in advance (through a user sign-up procedure, etc.), and selects the registered real estate indicated by the selection information to the candidate roommates. And can be matched.

The roommate matching apparatus 100 compares user information and room images of a plurality of candidate roommates with user information and room images received from the user terminal 200, and based on the comparison result, among the candidate roommates. You can decide on a recommended roommate. In this case, user information about candidate roommates may be compared with user information received from the user terminal 200, and room images of candidate roommates may be compared with room images received from the user terminal 200. .

The roommate matching apparatus 100 compares user information on the candidate roommates with user information received from the user terminal 200 to select primary candidate roommates from among the candidate roommates, and selects a room image for the primary candidate roommates. The roommates may be compared with room images received from the user terminal 200 to determine a recommended roommate among primary candidate roommates. For example, the roommate matching apparatus 100 is the same as whether or not smoking included in the user information of the user terminal 200 among user information on candidate roommates, the age is within a preset error range, and the purpose of residence is Candidate roommates corresponding to the same user information may be determined as primary candidate roommates.

In particular, the roommate matching apparatus 100 compares the room images of the primary candidate roommates with the room images received from the user terminal 200 to determine the most similar primary candidate roommates in the type of furniture or object to be used and the furniture arrangement structure. It can be decided as a recommended roommate. The roommate matching apparatus 100 may transmit a message indicating the determined recommended roommate to the user terminal 200. The message indicating the recommended roommate may include at least part of user information corresponding to the recommended roommate. For example, the message indicating the recommended roommate may include at least one of age, gender, address, and smoking status of the recommended roommate.

For example, the real estate registration terminal 300 or the user terminal 200 can communicate with a desktop computer, a laptop computer, a notebook, a smart phone, and a tablet PC. ), mobile phone, smart watch, smart glass, e-book reader, portable multimedia player (PMP), portable game console, navigation device, digital camera , DMB (digital multimedia broadcasting) player, digital audio recorder, digital audio player, digital video recorder, digital video player, PDA (Personal Digital Assistant) ), etc.

FIG. 2 is an exemplary diagram illustrating a user interface through which the roommate matching apparatus of FIG. 1 acquires a room image.

Referring to FIG. 2, the roommate matching apparatus 100 may transmit a floor plan of the registered real estate indicated by the selection information to the user terminal 200. In this case, the floor plan may include an image upload interface corresponding to each of at least one room, a kitchen, and a bathroom constituting the registered real estate indicated by the selection information.

The user terminal 200 may display the received floor plan to the user through a display, and the user may use at least one room, a kitchen, and a registered real estate using an image upload interface included in the floor plan. And room images corresponding to at least one of the bathrooms may be transmitted to the roommate matching apparatus 100.

For example, the user terminal 200 uses a roommate matching device ( 100). In the same way, the user terminal 200 uses the image upload interface corresponding to the room 2 of the floor plan to match the room image captured for one of the rooms of the real estate in which the user resides (for example, the second largest room). Can be sent to (100). In addition, the user terminal 200 may transmit a room image photographed about the kitchen of the real estate in which the user resides to the roommate matching device 100 through an image upload interface corresponding to the kitchen of the floor plan.

The roommate matching device 100 may store the room image received through the image upload interface corresponding to room 1 of the floor plan in correspondence with room 1 of the registered real estate, and the received through the image upload interface corresponding to room 2 of the floor plan. The room image may be stored in correspondence with room 2 of the registered real estate, and the room image received through the image upload interface corresponding to the kitchen of the floor plan may be stored in correspondence with the kitchen of the registered real estate.

That is, through the user interface using the floor plan, the roommate matching device 100 can determine whether the room image received from the user terminal 200 corresponds to at least one of the at least one room, kitchen, and toilet constituting the registered real estate. Also, it is possible to improve the user's convenience in uploading room images.

3 is a first exemplary diagram for explaining a process of comparing a room image of a primary candidate roommate with a room image received from a user terminal according to an exemplary embodiment. 4 is a second exemplary diagram illustrating a process of comparing a room image of a primary candidate roommate and a room image received from a user terminal according to an exemplary embodiment.

The roommate matching apparatus 100 identifies at least one object included in each of the room images by performing object identification on each of the room images of primary candidate roommates, and At least one object may be identified by performing object identification on the image.

For example, referring to FIG. 3, the roommate matching apparatus 100 may identify at least one object included in the first image IMG1 among room images of primary candidate roommates. The roommate matching apparatus 100 may identify a sofa SFA1, a television TV1, a dining table CTBL1, and a chair CHR1 included in the first image IMG1. Also, the roommate matching apparatus 100 may identify at least one object in the second image IMG2 received from the user terminal 200. The roommate matching apparatus 100 may identify a television TV2, two chairs CHR2 and CHR3, and a sofa SFA2 included in the second image IMG2.

Here, object identification may use an object identification algorithm based on a convolutional neural network (CNN) or a recurrent neural network (RNN). Specifically, the object identification algorithm is a Single Shot Detector (SSD) algorithm (Reference: W. Liu, et al, SSD: Single Shot Multibox Detector, 2016, ECCV) and/or You only Look Once (YOLO) algorithm (Reference Redmon, J., Divvala, S., Girshick, R., & Farhadi, A. (2016).You only look once: Unified, real-time object detection.In Proceedings of the IEEE conference on computer vision and pattern recognition pp. 779-788). Accordingly, when object identification is performed according to the object identification algorithm, each of the identified objects as shown in FIG. 3 may be identified in the form of a bounding box.

The roommate matching apparatus 100 may match at least one object included in the first image IMG1 and at least one object included in the second image IMG2 based on the identity of the object. For example, the roommate matching device 100 matches the sofa SFA1 included in the first image IMG1 with the sofa SFA2 included in the second image IMG2, and The included TV (TV1) is matched with the TV (TV2) included in the second image (IMG2), and the chair (CHR1) included in the first image (IMG1) is matched to the chair (CHR2) included in the second image (IMG2). ) Can be matched. At this time, since the two chairs CHR2 and CHR3 included in the second image IMG2 are all recognized as'chairs' by the object identification algorithm, when matching based on the identity of the object, the two chairs CHR2 , CHR3) may be matched with the chair CHR1 included in the first image IMG1.

As such, when there are objects for which 1:n (n is a natural number of 2 or more) matching as a result of the matching, the roommate matching apparatus 100 determines the similarity between the objects for which 1:n matching is established, and the first The 1:n matching may be corrected by 1:1 matching by matching objects that are most similar between the image IMG1 and the second image IMG2.

For example, referring to FIG. 3, the roommate matching device 100 may best match the chair CHR1 included in the first image IMG1 among the chairs CHR2 and CHR3 included in the second image IMG2. The similar chair CHR2 may be matched 1:1 with the chair CHR1 included in the first image IMG1.

Specifically, in order to determine the similarity between objects, the roommate matching apparatus 100 includes pixels of bounding boxes constituting at least one object included in the first image IMG1 among objects for which 1:n matching is established. Difference pixel values are calculated by differentiating the values from pixel values of the bounding box constituting at least one object included in the second image IMG2, and two objects having the smallest sum of the calculated difference pixel values are 1 It can be matched with :1. For example, the roommate matching device 100 uses the pixel values of the bounding box constituting the chair CHR2 included in the second image IMG2 to be bounded constituting the chair CHR1 included in the first image IMG1. The first sum value of the difference pixel values is calculated by differentiating from the pixel values of the box, and the pixel values of the bounding box constituting the chair CHR3 included in the second image IMG2 are included in the first image IMG1. The second sum value of the difference pixel values is calculated by differentiating from the pixel values of the bounding box constituting the chair CHR1, and the bounding corresponding to the first sum value, which is the smallest value among the first sum value and the second sum value. The chair CHR2 of the box may be matched with the chair CHR1 included in the first image IMG1.

Referring to FIG. 4, the roommate matching apparatus 100 may select a reference object from among objects matched 1:1 in the first image IMG1 and the second image IMG2. The roommate matching apparatus 100 may select a reference object according to a room type (room, kitchen, toilet, etc.) corresponding to the first image IMG1 and the second image IMG2.

For example, when the room type corresponding to the first image IMG1 and the second image IMG2 is a room (or living room), the roommate matching device 100 is a 1:1 matched TV (TV1:TV2) , Sofa (SFA1: SFA2), chair (CHR1: CHR2), a TV can be selected as a reference object. In this case, the roommate matching device 100 may determine a reference object in advance according to the room type and store it in the storage device 160. For example, if the room type is a living room, a TV may be previously determined as a reference object, and if the room type is a kitchen, tableware may be previously determined as a reference object.

When the reference object is selected, the roommate matching device 100 calculates first direction vectors vx1 and vx2 indicating 1:1 matched objects with respect to the reference object in the first image IMG1, and In the 2 image IMG2, second direction vectors vy1 and vy2 indicating 1:1 matched objects based on the reference object may be calculated.

Referring to FIG. 4, the roommate matching apparatus 100 indicates a sofa SFA1 and a chair CHR1 matched 1:1 with respect to a TV1 as a reference object in a first image IMG1. Direction vectors (vx1, vx2) can be calculated. In addition, the roommate matching device 100 includes a sofa SFA2 and a chair CHR2 matched 1:1 with a reference object TV2 in the second image IMG2. The indicated second direction vectors vy1 and vy2 may be calculated. Here, the direction vectors (vx1, vx2, vy1, vy2) have the distance from the reference object to each of the 1:1 matched objects as the size, and the direction from the reference object to the 1:1 matched objects is the direction angle. You can have it.

In this case, the relative distances between the objects may be different according to the angle and distance at which the first image IMG1 and the second image IMG2 are photographed. Therefore, the roommate matching device 100 may correct the size of the first direction vectors (vx1, vx2) and the second direction vectors (vy1, vy2) to reflect the relative distance difference according to the shooting angle and distance. I can.

For example, the roommate matching apparatus 100 may calculate a size ratio between bounding boxes between 1:1 corresponding objects and correct the direction vectors to correspond to the calculated size ratio. Referring to FIG. 4, the roommate matching apparatus 100 includes a size between the bounding box size of the television TV1 included in the first image IMG1 and the bounding box size of the television TV2 included in the second image IMG2. A first ratio of is calculated, and a second ratio between the size of the bounding box of the sofa SFA1 included in the first image IMG1 and the bounding box size of the sofa SFA2 included in the second image IMG2 is calculated. Then, a third ratio between the size of the bounding box of the chair CHR1 included in the first image IMG1 and the size of the bounding box of the chair CHR2 included in the second image IMG2 is calculated. The average value of the 3 ratio is calculated, and the size of the direction vectors may be corrected by multiplying the calculated average value by the first direction vectors vx1 and vx2 or by multiplying the second direction vectors vy1 and vy2.

When the size of the direction vectors is corrected, the roommate matching device 100 calculates and calculates Euclidean distances between the first direction vectors (vx1, vx2) and the second direction vectors (vy1, vy2). The summed Euclidean distances can be summed to calculate the summed Euclidean distance.

Next, the roommate matching apparatus 100 is a room corresponding to the smallest sum Euclidean distance among the summed Euclidean distances calculated as a result of comparing the room images of the first candidate roommates and the room image received from the user terminal 200. A first candidate roommate having an image may be determined as a recommended roommate.

That is, the roommate matching apparatus 100 according to an embodiment of the present invention compares room images of real estate currently being used by each of the roommates to determine the identity of the objects in the room, and the identity of the objects is recognized. By indicating the arrangement positions of the remaining objects centered on the reference object among 1:1 matching objects as direction vectors, it is possible to provide a roommate with the same or similar object and furniture arrangement to the user as a recommended roommate. .
