[0032] In addition, the embodiments described herein are described with reference to cross-sectional views and / or schematic diagrams that are ideal exemplary views of the present invention. Therefore, the shapes of the exemplary views may be modified depending on manufacturing techniques and / or tolerances. In addition, in each drawing shown in the present invention, each component may be slightly enlarged or reduced in size for convenience of explanation. The same reference numerals refer to the same components throughout the specification.

[0033] The term "mapping" as referred to below may refer to the act of linking certain data to corresponding data.

[0034] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings for explaining a driving video and location recording system according to an embodiment of the present invention. 1 is a block diagram of a driving video and location recording system according to an embodiment of the present invention.

[0035] 1, a driving video and location recording system 1 according to an embodiment of the present invention may include a black box 10 and a user terminal 20. Here, the configurations of the black box 10 and the user terminal 20 described below are for clarifying the disclosure of the present invention, and the present invention is not limited to the illustrated configurations.

[0036] For example, there may be an embodiment in which the components constituting the black box 10 are installed in the user terminal 20 as necessary. Or, there may be an embodiment in which the components constituting the user terminal 20 are installed in the black box 10 as necessary. Or, there may be an embodiment in which all the components of the driving video and position recording system 1 are installed in either the black box 10 or the user terminal 20.

[0037] In addition, although the components of the black box 10 and the user terminal 20 mentioned below are classified as components different from each other in terms of their functions, in reality, one or more components may be embodied by a single processing unit or a program recorded on a recording medium.

[0038] The black box 10 may be a recording device installed inside a vehicle to capture and record the external environment of the vehicle. The black box 10 may include a location information acquisition unit 110, an image capture unit 120, an image recording unit 130, a control unit 140, a sound signal recognition unit 150, a drive recording unit 160, and an interface 170.

[0039] The location information acquiring unit 110 may be a unit that grasps the location information of the automobile. For example, the location information acquiring unit 110 may be provided with a GPS receiver and receive GPS information. The location information acquiring unit 110 may be built inside a housing that forms the framework of the black box 10. As another example, the location information acquiring unit 110 may be built into the automobile and the black box 10 may be connected thereto to acquire GPS information.

[0040] While the vehicle is traveling, the location information acquiring unit 110 may continuously receive and record GPS information. For example, the location information acquiring unit 110 may grasp and record the location of the vehicle at preset intervals. The location information grasped by the location information acquiring unit 110 may be recorded in an SD card, which will be described later.

[0041] The image capturing unit 120 may capture an image of the external environment of the vehicle. To this end, the image capturing unit 120 may include a lens exposed from a housing and an image sensor built into the housing for converting information acquired by the lens into an electrical signal.

[0042] The image recording unit 130 can record the image captured by the image capturing unit 120. The image recording unit 130 can receive an electrical signal from the image sensor and record the image captured by the image capturing unit 120 in a preset format. The image recording unit 130 may be built into the housing of the black box 10.

[0043] For example, the image recording unit 130 may record the images captured by the image photographing unit 120 in the form of a video. For convenience of explanation, a video that captures at least a part of the driving process of the automobile is hereinafter referred to as a driving video. The image recording unit 130 may record a plurality of driving videos that are sequentially captured while the automobile is driving.

[0044] Each driving video may be recorded together with location information of the location where the video was taken. More specifically, the driving video may be recorded together with location information of the vehicle's position when the video started (start position) and the vehicle's position when the video ended (end position).

[0045] The running video may be recorded to have a preset running time, and the end position of the running video previously recorded and the start position of the running video to be recorded immediately after may be set to be the same or adjacent to each other.

[0046] Meanwhile, the image recording unit 130 may include a recording medium for recording images. Such a recording medium may be, for example, an SD card. The SD card may be inserted through a groove formed in the housing.

[0047] The control unit 140 may be a processing unit that controls the image capturing unit 120, the image recording unit 130, the drive recording unit 160, the interface 170, etc. in response to various inputs and signals. For example, the control unit 140 can control other components of the black box 10 in response to an operation of the interface 170. Alternatively, the control unit 140 can change the content displayed on a screen included in the black box 10 (hereinafter, a black box screen) by operating the interface 170.

[0048] The sound signal recognition unit 150 may be configured to recognize a sound signal generated from the outside. For example, the sound signal may be a preset command word. Or, the sound signal may be a sound of a predetermined decibel or more. In this case, the predetermined decibel may be a value set in consideration of an impact sound of a car accident.

[0049] When a preset sound signal is recognized, the sound signal recognition unit 150 may output a corresponding recognition signal to the control unit 140. The control unit 140 may control each component of the black box 10 based on the recognition signal so that a drive record is recorded in the drive recording unit 160. This will be described later.

[0050] The driving recorder 160 may record a driving record based on the recognition of the sound signal. The driving record may include the position information of the vehicle at the time when the sound signal is recognized, and an image captured by the image capturer 120 at the time when the sound signal is recognized. The driving record may be recorded in a recording medium, like a driving video, or may be recorded in an SD card inserted in the black box.

[0051] As an example, the video captured by the image capture unit 120 is displayed in real time on a black box screen, and when a sound signal is recognized, the control unit 140 can screen capture the still image displayed on the black box screen and include it in the drive recording.

[0052] The interface 170 may be configured to provide a user interface for the black box 10. For example, the interface 170 may include a touch screen panel coupled to a black box screen, switches formed on the housing, etc.

[0053] The interface 170 can provide an input for deleting the driving record and the driving video stored in the SD card, and can also provide an input for starting or stopping the image capture unit 120.

[0054] The user terminal 20 may be an information processing unit capable of wired and / or wireless communication with the black box 10. The user terminal 20 may be a personal information processing terminal such as a desktop, a laptop, a smartphone, a PDA, or the like.

[0055] The user terminal 20 can receive necessary information from the black box 10 through wired / wireless communication. For example, the user terminal 20 can load information recorded in an SD card through a wired / wireless communication method. The user terminal 20 may include a driving route generating unit 210, a video mapping unit 220, a display unit 230, and a record display unit 240.

[0056] First, the driving path generating unit 210 may be configured to generate a driving path for the vehicle. To generate the driving path, the driving path generating unit 210 may load a plurality of pieces of position information acquired while the vehicle is traveling. The driving path may be modeled in the form of a line having a thickness that represents the moving path of the vehicle.

[0057] Meanwhile, the driving route generating unit 210 may load a map of the vicinity of the location information in order to provide surrounding information of the driving route together. At this time, the map may be loaded based on the location information loaded from the black box 10. For example, the user terminal 20 may have a map pre-recorded therein or may be provided with the map via the Internet.

[0058] The driving route generating unit 210 can generate a driving route model based on the generated driving route and the loaded map. Specifically, the driving route generating unit 210 can match position information, which is the basis for generating the driving route, with points on the map to grasp the part indicated by the driving route on the map. Thereafter, the driving route generating unit 210 generates a driving route model in which the driving route is mapped on the map. The driving route model may be a two-dimensional image model in which the driving route is mapped on the map. As an example, the driving route model may be embodied in a KML file format.

[0059] The driving route generation unit 210 is configured to map a driving video onto the driving route that appears in the driving route model. More specifically, the video mapping unit 220 can map a video of a section route onto each section route that constitutes the driving route. This will be described in detail with reference to FIG. 2.

[0060] The display unit 230 may include a screen of the user terminal 20 (hereinafter, referred to as a user terminal screen) and may be configured to display information on the screen of the user terminal. The display unit 230 may change the content displayed on the screen of the user terminal in response to the content inputted through an input unit of the user terminal 20. For example, the input unit may be a keyboard, a mouse, a touch screen, etc.

[0061] A dedicated application or program for generating, loading, and displaying a driving route model on a screen may be recorded in the user terminal 20. A user may generate a driving route model after executing the dedicated application or program. In addition, a user may load the generated driving route model, display it on a screen, and then play a mapped video. This will be described in detail later with reference to FIG. 3.

[0062] The record display unit 240 may display the recorded point on the driving route model so as to be visually recognizable. Here, the recorded point may be a location where a sound signal is recognized. To this end, the record display unit 240 may be configured to load a driving record or to allow a user to input a driving record. The record display unit 240 may distinguish the recorded point by using location information included in the driving record. The record display unit 240 may display the recorded point on the driving route so as to be distinguished from other points. This will be described later with reference to FIG. 3.

[0063] FIG. 2 is a diagram illustrating how a driving video and location recording system according to an embodiment of the present invention maps a video onto a driving route.

[0064] As shown in Fig. 2, the driving route generation unit 210 can generate a driving route model including a map and a driving route 310. In the example of Fig. 2, the driving route 310 represents a driving route in which an automobile starts at point a, passes through points b, c, and d, and arrives at point e. Here, for convenience of explanation, each position is represented as points a to e, but in reality, each point may be represented by GPS coordinates.

[0065] 2, the first running video 322, the second running video 324, the third running video 326, and the fourth running video 328 may be videos sequentially captured of the running route 310. The running route 310 can be divided into a plurality of section routes 312, 314, 316, and 318 by the captured first running video 322, the second running video 324, the third running video 326, and the fourth running video 328.

[0066] 2, a driving route 310 may be divided into a first section route 312, a second section route 314, a third section route 316, and a fourth section route 318. Such spatial division may be performed during the mapping process of the video mapping unit 220.

[0067] The video mapping unit 220 can obtain GPS coordinates of the start and end positions of the driving videos and obtain a portion of the driving route where the coordinates match. More specifically, the video mapping unit 220 can obtain the start and end positions of the driving videos 322, 324, 326, and 328 on the driving route, respectively, and set the section between the start and end positions as one section route. Then, the video mapping unit 220 can map the driving videos to the section route.

[0068] For example, after loading the first driving video 322, the video mapping unit 220 may determine a point a, which is the start position, and a point b, which is the end position, on the driving route 310. Thereafter, the route between the determined points may be set as a first section route 312, and then the first driving video 322 may be mapped to the first section route 312. Mapping the second driving video 324, the third driving video 326, and the fourth driving video 328 to the respective section routes 314, 316, and 318 is similar to the above, and therefore will not be described.

[0069] 3 is a diagram illustrating a driving route model and a sign image displayed on a screen of a display unit according to an embodiment of the present invention. As shown in FIG 3, when a user generates and loads a driving route model through a dedicated application or program, the driving route model M as shown in FIG 3 can be displayed on the screen of a user terminal.

[0070] 3 may be a driving route model onto which a driving video is mapped. The record display unit 240 may display a sign image 410, which allows the user to visually recognize where the recorded point is on the driving route 310 displayed on the screen, by overlapping it with the driving route model M.

[0071] The sign image 410 may include a recording point sign 416, an image display area 412, and an address display area 414. The recording point sign 416 may be an image indicating a recording point on the driving route 310. In the illustrated example, an arrow format is given as an example, but the present invention is not limited to this and may be expressed in various formats.

[0072] The record display unit 240 can define an image display area 412 and an address display area 414 in association with a recording location marker 416. A thumbnail image is loaded and displayed in the image display area 412, and the address of the recording location can be displayed in the address display area 414.

[0073] Here, displaying in association with each other may mean displaying in such a way that the user intuitively recognizes that the location indicated by recording location sign 416 is the location where the thumbnail image was taken, and that the address of the location indicated by recording location sign 416 is the displayed address.

[0074] 3, the record display unit 240 may display the image display area 412 and the address display area 414 adjacent to the arrow head portion of the recording point marker 416. Also, the record display unit 240 may display the tail portion of the recording point marker 416 adjacent to the recording point.

[0075] The thumbnail image may be displayed by loading a still image included in the drive record. Also, the address displayed in the address display area 414 may be an address determined using location information included in the drive record.

[0076] Meanwhile, the user can select a driving route and / or a thumbnail image to play a driving video on the screen. For example, the user can input a section route selection input for selecting a section route and an image selection input for selecting a thumbnail image to the user terminal 20. Such inputs can be implemented in various ways, such as touching a touch panel, input using a keyboard, clicking using a mouse, etc.

[0077] The section route selection input may be an input by the user to select a specific point on the travel route. In this case, a video mapped to the section route including the selected point may be displayed on the screen. The image selection input may be an input by the user to select a thumbnail image. In this case, a video mapped to the section route including the recording point may be displayed on the screen.

[0078] Here, a section route including a selected point may mean that the coordinates of the selected point (or the recorded point, if a thumbnail image is selected) are located between the start point and end point of the section route.

[0079] Hereinafter, a driving video and location recording method according to an embodiment of the present invention will be described with reference to the above description. For convenience of explanation, parts that are the same as or similar to the above embodiment will be referred to by the same reference numerals, and descriptions of common parts will be omitted.

[0080] 4 is a flow chart of a method for recording driving images and positions according to an embodiment of the present invention. The method for recording driving images and positions according to an embodiment of the present invention can be implemented using the driving image and position recording system 1 according to the embodiment of the present invention described above.

[0081] As shown in FIG. 4, a driving video and location recording method according to one embodiment of the present invention may include a step of acquiring vehicle location information (S101); a step of recording video and location information of the shooting location (S102); a step of recognizing an audio signal (S103); a step of recording a driving record (S104); a step of generating a driving route (S105); a step of mapping the video (S106); a step of displaying the driving route and the driving record (S107); and a step of displaying a selected video (S108).

[0082] In a step of acquiring vehicle location information (S101), a user drives the vehicle, and the location information acquiring unit 110 can acquire and record location information according to the driving of the vehicle.

[0083] In the step of recording the video and the position information of the shooting position (S102), the start position and end position of the running video can be recorded together with the running video. In the step of recognizing a sound signal (S103), the black box 10 can recognize a preset sound signal. For example, the preset sound signal may be a voice signal including a specific keyword or sentence. As an example, in this step, the user can speak a preset keyword / sentence such as "Hi, BG. Record this" or "Hi, BG. Check-point." When the preset keyword / sentence is recognized, the sound signal recognition unit 150 can output a recognition signal based thereon.

[0084] In a step of recording a drive record (S104), the control unit 140 transmits a control signal to the drive record unit 160 in response to the recognition signal. The drive record unit 160 to which the control signal is transmitted can record a drive record including current position information and a still image.

[0085] In the step of generating a driving route (S105), after the user executes a dedicated application or program, the user can load location information acquired and recorded during driving. When the location information is loaded, the driving route generating unit 210 can load a map according to the location information. When the location information and the map are loaded, the driving route generating unit 210 can generate a driving route model.

[0086] In the step of mapping the video (S106), a dedicated application or program may load the driving video and then map it to each section of the route. This step may be performed automatically after generating the driving route model, or this step may be performed after receiving additional input from the user.

[0087] In the step of displaying the driving route and the driving record (S107), the display unit 230 may display a driving route model and a sign image on the screen of the user terminal. This step may be performed automatically after the video mapping is completed. Alternatively, this step may be performed after receiving additional input from the user.

[0088] In a step of displaying the selected video (S108), the user may input a section route selection input or an image selection input to the user terminal 20. The display unit 230 may display a mapped video on the screen in response to the input content.

[0089] Those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features of the present invention. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and are not limiting. The scope of the present invention is defined by the claims rather than the above detailed description, and all modifications and variations derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
