Apparatus and method for recording accident image}

The present invention relates to an apparatus and method for providing a surrounding image of a vehicle, and more particularly, when an accident occurs during a parking stop, for example, a situation such as a forced door opening and theft while parking or a contact accident due to the approach of another vehicle. In this case, the present invention relates to an accident image recording apparatus and a method for providing a composite image viewed from a location where an accident occurs by projecting a plurality of images photographed for a predetermined time on a three-dimensional projection surface.

In general, there is no universal system installed in the vehicle to capture and display the surrounding image of the vehicle, so the driver can check the surroundings of the vehicle only through his / her own eyes or the rear through the inside mirror or the outside mirror. This has been made forward, backward or turning.

However, some vehicles can sit in the driver's seat and easily check the surrounding environment of the front and rear, and there are blind spots that cannot be seen through the naked eye or mirrors.

Therefore, recently, an apparatus for photographing a surrounding environment through a camera installed in front, rear, left, and right directions of a vehicle, and displaying the surrounding image of the vehicle through a display device provided in the vehicle by combining the photographed images has been developed.

Such devices typically take a picture to obtain the environment information of the vehicle while driving and provide the image to the driver.

However, in addition to such driving conditions, the driver obtains image information about a situation where the driver is not in the vehicle, that is, an accident that may occur during parking or stopping, and later provides the image as a composite image on a three-dimensional projection surface. There is a need for an apparatus and method for identifying accurate situational information on an accident in the absence of an emergency.

The plurality of cameras 111 to 114 may not photograph the situation around the vehicle when the vehicle in which the accident image recording apparatus according to the present invention is installed is not in operation. However, at any point in time, it is activated according to a control signal from the control unit 300 to perform photographing of a situation around a vehicle or an interior of a vehicle for a predetermined period, and store a photographing result performed for a predetermined period of time.

As another embodiment, photographing may be continuously performed while driving or parking, and a plurality of images photographed for a predetermined time before and after the accident occurrence may be stored.

In the exemplary embodiment of the present invention, a case in which the plurality of cameras 111 to 114 are respectively installed in front, rear, left, and right directions of the vehicle 10 is described as an example. However, this is to assist in understanding the present invention. As an example, the present invention is not limited thereto, and the number or installation directions of the cameras may be variously changed according to a use and a need.

For example, when a plurality of cameras 111 to 114 have a wide angle lens having a large angle of view, the number of installations may be reduced, or when the plurality of cameras 111 to 114 have a camera angle with a small angle of view. The number may be increased. In this case, the images acquired by the plurality of cameras 111 to 114 may acquire an image about the surrounding omnidirectional direction of the vehicle 10, that is, 360 degrees, and the plurality of cameras (as in the embodiment of the present invention). When 111 to 114 are respectively installed in the front, rear, left, and right directions of the vehicle 10, each camera may be a camera using a wide-angle lens having an angle of view of 180 degrees.

In addition, in the embodiment of the present invention, the first camera 111 is installed in the center of the bone net, the second camera 112 is installed on the upper rear bumper of the vehicle 10, and the third and fourth cameras 113 , 114 will be described in the case of being installed in the left and right outside mirrors of the vehicle 10, for example, but this is only an example to help the understanding of the present invention is not limited thereto and a plurality of cameras (111 ~ 114) The installation position of) may be changed in various ways depending on the purpose and needs.

The image storage unit 120 may store images acquired by the plurality of cameras 111 to 114, and the image storage unit 120 may include a cache, RAM, SRAM, DRAM, ROM, PROM, EPROM, EEPROM, and flash memory. And a hard disk drive may be used, but is not limited thereto.

The image storage unit 120 stores images captured by the plurality of cameras 111 to 114 in response to an event from the outside of the vehicle sensed by the sensor 500. The image storage unit 120 may include a hard disk, a flash memory, a compact flash card (CF), a secure digital card (SD), a smart card (SM), a multimedia card (MMC), a memory stick, or the like. As a module capable of inputting / outputting information, the module may be provided inside the apparatus or may be provided in a separate apparatus.

The plurality of stored images are then projected onto the three-dimensional projection surface by the peripheral image generator 200 to generate a composite image in which the virtual viewpoint is moved to the accident occurrence position.

Meanwhile, the plurality of cameras 111 to 114 may convert the image into a compressed format to facilitate data transmission before transmitting the obtained image to the image storage unit 120. The compressed format may be MPEG-1 or Various known formats such as MPEG-4 may be used, and the plurality of cameras 111 to 114 may include a processor for converting a data format of an acquired image.

The peripheral image generating unit 200 may include a projection surface setting unit 210, a coordinate converter 220, and an image synthesizer 230.

The projection surface setting unit 210 may set a projection surface preset when the vehicle is shipped or a projection surface selected by the driver. For example, an optimal projection plane may be preset through various tests when the vehicle is shipped, or the driver may select a desired projection plane among various kinds of previously stored projection planes.

In the exemplary embodiment of the present invention, a case in which the projection surface is hemispherical will be described by way of example. However, this is only an example to help understanding of the present invention, and the present invention is not limited thereto, and various projection surfaces such as a sphere and a plane may be set. In the projection plane the vehicle may be located near the center of the projection plane or have any position.

The coordinate converter 220 may store coordinate information (for example, 3D coordinate information, etc.) of the set projection surface, and convert the coordinates of the image acquired by the image acquisition unit 100 using the stored coordinate information. Can be. For example, the coordinate converter 220 may convert two-dimensional coordinates of the image acquired by the image acquisition unit 100 into three-dimensional coordinates of the set projection plane.

The image synthesizing unit 230 generates a peripheral image by synthesizing the image acquired by the image obtaining unit 100 based on the coordinates converted by the coordinate converting unit 220 to the projection surface set by the projection surface setting unit 210. It becomes possible. For example, as illustrated in FIG. 3, the image synthesizing unit 230 converts the coordinates of the image acquired by the image obtaining unit 100 to the coordinates of the set projection surface, based on the converted coordinates. By synthesizing the image acquired by the image acquisition unit 100 to the set projection surface, it is possible to generate the surrounding image, the shape of the vehicle 10 in the generated surrounding image may be a preset form or have a form selected by the driver. have.

As such, when the surrounding image is generated by synthesizing the image acquired by the image obtaining unit 100 with the projection surface 140 set around the vehicle 10, the surrounding image may be displayed in a two-dimensional or three-dimensional form. By changing the line of sight as shown by the arrow of FIG. 3, the virtual viewpoint can be moved to a position where an accident occurs and viewed in the direction viewed. In addition, since the distance to the vehicle 10 can also be changed in changing the direction of the eye, it is possible to view at a desired scale.

When the controller 300 detects that an event from the outside of the vehicle 10 has occurred through the sensor 500, the controller 300 activates storage of captured images in different directions by the image acquirer 100, or the surrounding image. Activate the generation unit 200 at the same time.

The present invention focuses on processing an event generated when a vehicle stops while the vehicle 10 does not operate, but this is always performed while the vehicle is running. The image capture unit 100 and the surrounding image generator 200 This is because the driver is projected through the control unit 300 and the display unit 400 to project a plurality of images photographed about a situation around the vehicle on a three-dimensional projection surface to provide a synthetic image viewed from a virtual viewpoint.

That is, even in a situation in which the driving of the vehicle and the corresponding components such as the image acquisition unit 100 do not operate, the controller may control to start the operation of the image acquisition unit 100 at any time when an external event occurs.

In the present invention, when an external event occurs, the image acquisition unit 100 preferentially captures and stores an image around or inside the vehicle, and later projects a plurality of images photographing different directions onto a three-dimensional projection surface at an accident occurrence time. Displaying the synthesized image viewed may be performed according to the command of the pepper user. However, it is not necessarily limited thereto, and it is obvious that the captured image may be directly displayed as a synthesized image viewed from an accident occurrence location, or the synthesized image may be stored and displayed later.

The event described in the present invention may be a forced door opening of the vehicle 10 or a contact accident of the other vehicle 20 with the vehicle 10. That is, a third party attempts to intrude into the vehicle or is in operation in a situation in which the driver is not present in the vehicle 10 in which the accident image recording apparatus according to the present invention is installed, for example, while the vehicle is parked or stopped. The case where 20 causes a contact accident on the vehicle 10 will mainly be an example of the event described in the present invention.

However, the event is not necessarily limited thereto. For example, it may be other actions by the third party to damage the vehicle 10. Alternatively, the event may not necessarily be caused by the vehicle from the outside but may be due to the inside of the vehicle, for example, an accident due to an explosion of a lighter or the like inside the vehicle during the summer.

That is, an accident that may affect the vehicle 10 by any cause caused by the outside or the inside of the vehicle 10 may be included in the category of the event used herein.

Sensor 500 used in the accident image recording apparatus according to the present invention may be a vibration sensor, the vibration sensor is detected by detecting the vibration and the location of the transmission to the vehicle 10 when the above-described event occurs Transmits to the control unit 300.

The controller 300 determines whether to view the detected information as a valid event. For example, the magnitude of the measured vibration may be compared with a preset threshold to consider it as a valid event if it is greater than this and indicate a response accordingly.

The controller 300 controls to store a plurality of images photographed for a predetermined period from the point of time determined as the valid event. The predetermined period may be set at the time of shipment of the vehicle or may be reset by the user. It is possible to prevent unnecessary memory or power consumption by capturing the surroundings of the vehicle by a plurality of cameras and storing them in a temporary buffer and storing a plurality of images captured for a predetermined time at the time when an event is detected.

A plurality of sensors 500 may be installed at various positions of the vehicle 10, and accordingly, the controller 300 checks the event occurrence position from the event occurrence signal detected by the sensor 500. The controller 300 controls the peripheral image generator 200 to move the virtual viewpoint to the event occurrence position with respect to the 3D projection plane.

The peripheral image generator 200 projects a plurality of captured images on a 3D projection surface to generate a composite image viewed from an event occurrence position which is a virtual viewpoint.

The display unit 400 displays a composite image viewed from the event occurrence position generated by the surrounding image generator 200, and the display unit 400 may use various display devices provided in the vehicle 10. For example, the display unit 400 may be a navigation device, a HUD display device, a display device mounted on an inside mirror or an outside mirror, an AV system, or the like.

Until now, each component of FIGS. 1, 2, and 4 may refer to software or hardware such as a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). However, the components are not limited to software or hardware, and may be configured to be in an addressable storage medium and configured to execute one or more processors. The functions provided in the above components may be implemented by more detailed components, or may be implemented as one component that performs a specific function by combining a plurality of components.

FIG. 6 is a schematic view showing an image of an accident image recording apparatus looking down when a side contact event occurs according to an embodiment of the present invention, FIG. 7 is an enlarged schematic view of a dotted line region of FIG. 6, and FIG. FIG. 6 is an exemplary view of a composite image viewed from an event occurrence time when an accident image recording apparatus according to an embodiment occurs.

The vehicle 10 in which the accident image recording apparatus according to the present invention is installed is parked or stopped without the driver's boarding, and the other vehicle 20 causes contact with the side of the vehicle 10 while driving or parking. Assume that

As described above with reference to FIG. 3 and corresponding specification parts, a virtual viewpoint is thought by projecting and synthesizing a plurality of images acquired by the image obtaining unit 100 onto a three-dimensional projection surface on the projection surface 140 forming the periphery of the vehicle 10. In the case of generating the surrounding combined image viewed by moving to the occurrence position, the surrounding composite image can be displayed in the form of 2D or 3D image, and the virtual view is changed to the position where the accident occurred by changing the direction of eye as shown by the arrow of FIG. You can see it by moving it. Accordingly, the images stored in the image storage unit 120 may be presented to the manager of the vehicle 10 in a form as viewed from the event occurrence position (virtual view point) as shown in FIG. 6.

In addition, since the distance to the vehicle 10 may also be changed in changing the direction of the eyes, it may be viewed at a desired scale, and thus, a portion in which a contact accident occurs as shown in FIG. 7 may be presented as an enlarged composite image.

Furthermore, if the gaze direction is selected as the gaze direction facing in the lateral direction at the time of occurrence of the event of the vehicle 10 in which an accident occurs from the front, the image as shown in FIG. 8 may be presented to the user. The owner or manager of the vehicle 10 obtains specific information such as the number of the vehicle that caused the contact accident, thereby preparing for a hit and miss accident.

As another example, when a third party who is not an administrator of the vehicle 10 attempts to open the door by force or attempts to damage the vehicle 10, the detailed information about the surrounding situation of the vehicle 10 is similarly provided. Can be acquired and saved.

FIG. 9 is a schematic diagram illustrating an image obtained by synthesizing an image captured by an accident image recording apparatus according to an embodiment of the present disclosure, on a three-dimensional projection surface for a forced door opening event.

When the sensor 500 detects a forced door opening attempt by a third party, the sensor 500 transmits it to the controller 300, and when the controller 300 detects this as a valid event, the sensor 500 stores the captured images in different directions. By using a plurality of cameras (111 to 114) installed in a plurality of locations of the (10) stores an image of the surrounding situation of the vehicle at that time.

As described above with reference to FIG. 3, the stored images are synthesized such that various changes in the line of sight direction and distance with the vehicle 10 are possible, thereby securing specific information about the appearance of a third party.

According to an embodiment of the present invention, an accident image recording method includes detecting an event around a vehicle or an interior of the vehicle through a sensor, and recording and storing an image of at least one direction or the interior of the vehicle around the vehicle. And generating a surrounding image of the vehicle by synthesizing the stored image with a projection surface set around the vehicle. This will be described with reference to FIGS. 10 and 11.

10 and 11 are block diagrams illustrating an accident image recording method according to an embodiment of the present invention.

Even when the vehicle is not in operation, the sensor monitors an event that may occur in or around the vehicle (S810). When an event occurs, for example, when there is a contact of another vehicle in a parking state, the sensor detecting the vibration and the event occurrence position transmits the detected information to the controller, and the controller compares the received measurement with a preset threshold. (S820). When it is determined that the measured vibration is a valid event such as when the measured vibration is greater than a preset threshold (Y in S820), the image acquisition unit activates storing of captured images in different directions (S830).

Specifically, as described above, the recording may be started from the occurrence of an event to store a plurality of images captured during a predetermined period after the occurrence of the event. However, as another embodiment, the photographing may be always performed even while driving and at a stop, and when the event occurs, only the photographed image may be stored for a predetermined period before and after the event occurs.

The image data stored in this way is synthesized on a three-dimensional projection surface when presented with a user's display request (Y in S910) and presented to the user. To this end, a projection surface forming a vehicle periphery is set (S920), the coordinates of the stored image are converted into coordinates of the projection surface (S930), and the stored image is synthesized on the projection surface based on the converted coordinates (S940). The synthesized image is presented to the user as a 2D or 3D image (S950).

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
