1 is a block diagram illustrating an example of a camera control apparatus according to the present invention.

The camera control device refers to a device for controlling a vehicle.

For example, the camera control device may be a device that is mounted on a vehicle, performs communication through CAN communication, and generates a message for controlling the vehicle and/or electric equipment mounted on the vehicle.

As another example, the camera control device may be located outside the vehicle like a server or a communication device and communicate with the vehicle through a mobile communication network. In this case, the camera control device may remotely control a vehicle and/or an electric device mounted on the vehicle using a mobile communication network.

The camera control device 100 is provided in a vehicle, and may be an independent device that can be attached to or detached from the vehicle, or may be integrally installed in the vehicle and be a part of the vehicle.

Referring to FIG. 1 , the camera control apparatus 100 includes a communication unit 110 and a processor 130 .

The communication unit 110 is configured to communicate with various components provided in the vehicle. For example, the communication unit 110 may receive various types of information provided through a controller are network (CAN). As another example, the communication unit 110 may communicate with all communicable devices such as a vehicle, a mobile terminal and a server, and another vehicle. This may be called V2X (Vehicle to everything) communication. V2X communication can be defined as a technology for exchanging or sharing information such as traffic conditions while communicating with road infrastructure and other vehicles while driving.

The communication unit 110 may receive information related to driving of the vehicle from most of the electronic devices provided in the vehicle. Information transmitted to the camera control device 100 from the electrical equipment provided in the vehicle is referred to as 'vehicle driving information'.

The vehicle driving information includes vehicle information and surrounding information of the vehicle. Based on the frame of the vehicle, information related to the inside of the vehicle may be defined as vehicle information, and information related to the outside of the vehicle may be defined as surrounding information.

The vehicle information means information about the vehicle itself. For example, vehicle information includes vehicle travel speed, travel direction, acceleration, angular speed, location (GPS), weight, number of passengers in the vehicle, vehicle braking force, maximum vehicle braking force, air pressure of each wheel, and centrifugal force applied to the vehicle. , the driving mode of the vehicle (whether autonomous driving mode or manual driving), the vehicle parking mode (autonomous parking mode, automatic parking mode, manual parking mode), whether a user is in the vehicle, and information related to the user may include

The surrounding information means information about other objects located within a predetermined range around the vehicle and information related to the outside of the vehicle. For example, the condition of the road surface (friction force) on which the vehicle is traveling, the weather, the distance to the front (or rear) vehicle, the relative speed of the front (or rear) vehicle, the curvature of the curve when the driving lane is a curve, the vehicle Ambient brightness, information related to an object existing in a reference area (constant area) with respect to the vehicle, whether an object enters/leaves into the predetermined area, whether a user exists around the vehicle, and information related to the user (e.g., For example, whether the user is an authenticated user), and the like.

In addition, the surrounding information includes ambient brightness, temperature, sun position, object information located in the vicinity (person, other vehicle, sign, etc.), the type of road surface being driven, topographical features, lane information, and driving lane (Lane). ) information, and information necessary for autonomous driving/autonomous parking/automatic parking/manual parking modes.

In addition, the surrounding information includes an object (object) existing in the vicinity of the vehicle and the distance to the vehicle, the possibility of collision, the type of the object, a parking space in which the vehicle can be parked, and an object (eg, a parking line) for identifying a parking space. , string, other vehicles, walls, etc.) may be further included.

The vehicle driving information is not limited to the example described above, and may include all information generated from components included in the vehicle.

Meanwhile, the processor 130 is configured to control one or more electrical components provided in the vehicle using the communication unit 110 .

Specifically, the processor 130 may determine whether at least one of a plurality of preset conditions is satisfied based on the vehicle driving information received through the communication unit 110 . According to a satisfied condition, the processor 130 may control the one or more electronic devices in different ways.

In relation to a preset condition, the processor 130 may detect that an event has occurred in an electric device and/or an application provided in the vehicle, and determine whether the detected event satisfies a preset condition. In this case, the processor 130 may detect that an event has occurred from information received through the communication unit 110 .

The application is a concept including a widget or a home launcher, and means any type of program that can be driven in a vehicle. Accordingly, the application may be a program that performs functions of a web browser, video playback, message transmission and reception, schedule management, and application update.

Further, the application is a Forward Collision Warning (FCW), Blind Spot Detection (BSD), Lane Departure Warning (LDW), Pedestrian Detection (PD), Curve Speed Warning It may include at least one of (Curve Speed Warning, CSW) and turn by turn navigation (TBT).

For example, event occurrence may occur when there is a missed call, when there is an application to be updated, when a message arrives, start on, start off, autonomous driving on/off, display activation key press (LCD awake key), an alarm (alarm), a call connection (Incoming call), may be a missed notification (missed notification) and the like.

As another example, the event may be a case in which a warning set in an advanced driver assistance system (ADAS) is generated or a function set in the ADAS is performed. For example, when a forward collision warning occurs, when a blind spot detection occurs, when a lane departure warning occurs, when a lane keeping assist warning), it may be considered that an event has occurred when an autonomous emergency braking function is performed.

As another example, when changing from a forward gear to a reverse gear, when an acceleration greater than a predetermined value occurs, when a deceleration greater than a predetermined value occurs, when a power unit is changed from an internal combustion engine to a motor, or when a motor Even when the engine is changed to an internal combustion engine, it can be considered that an event has occurred.

As another example, the event may be that a message requesting a predetermined image from at least one of an application installed in the vehicle and an electrical device mounted in the vehicle is received by the camera control device 100 .

In addition, it can be considered that an event has occurred even when various ECUs provided in the vehicle perform specific functions.

For example, when the event that occurred satisfies a preset condition, the processor 130 may control the communication unit 110 to display information corresponding to the satisfied condition on one or more displays provided in the vehicle. can

The communication unit 110 may be connected to a plurality of cameras mounted on the vehicle by wire and/or wirelessly to communicate with the cameras.

The processor 130 may control the plurality of cameras through the communication unit 110 . For example, the processor 130 may generate a control signal for controlling the plurality of cameras.

The processor 130 may receive an original image from the plurality of cameras, and generate a processed image required for an event from the original image. The generated processed image may be transmitted to a place requested by the event through the communication unit 110 . For example, it may be stored in a memory provided in the vehicle, transmitted to an electric device provided in the vehicle, or transmitted to a server or cloud.

The camera control apparatus 100 according to the present invention may simultaneously generate a plurality of images that can be used for various purposes by using a plurality of cameras mounted on a vehicle. For example, the display may request an image of the rear of the vehicle, and a server that remotely controls the vehicle may request the image of the rear of the vehicle. At this time, since the characteristics of the image requested by the display and the server are different, the camera control device 100 receives the original image from the vehicle rear camera for photographing the rear of the vehicle, and the first vehicle rear image for display and the second vehicle for the server The rear image can be created at the same time and transmitted to the display and the server respectively.

Hereinafter, the operation of the camera control apparatus 100 will be described in more detail with reference to the accompanying drawings.

FIG. 2 is a flowchart illustrating a method of controlling the camera control apparatus of FIG. 1 .

The processor 130 receives an original image from a certain camera (S210). The processor 130 may simultaneously receive a plurality of original images from a plurality of cameras, but for convenience of description, a case in which an original image is received from any one camera will be described as an example.

Next, when the first event occurs, the processor 130 generates a first processed image by using the original image (S230).

Here, the event may be that a message requesting a predetermined image is received from at least one of an application installed in the vehicle, an electrical device mounted on the vehicle, and a system.

For example, when the Around View Monitor (AVM) is running, a message requesting a left image, a right image, a front image, and a rear image may be received. When the parking assistance system is running, a message requesting a rear view image may be received. For another example, in case of an emergency, a message requesting a vehicle interior image taken from the interior of the vehicle may be received from the service center.

The event may be a preset case in which boarding or disembarking of a passenger occurs. For example, when at least one of the doors provided in the vehicle is opened, a message requesting a seat image obtained by photographing a seat corresponding to the at least one may be received. The photographed seat image may be compared before and after the passenger boards, and may be used to search for items left by the passenger in the vehicle.

The processor 130 selects at least one of a plurality of cameras mounted on the vehicle based on the first event, and generates one processed image using one or more original images received from the selected camera. can In other words, the first processed image is generated by the first event.

A method and/or method of processing the first processed image is preset in the first event, and the processor 130 processes the first processed image in a method and/or method set in the first event. handle

The processor 130 may generate one processed image by processing one original image. For example, the processed image may be generated by using at least one of changing at least one of a size, a data rate, a magnification, a frame rate, and a resolution of the original image, and cutting a part of an entire area of the original image.

Furthermore, the processor 130 may synthesize a plurality of original images into one processed image or may generate a plurality of processed images by using the plurality of original images.

The processed image refers to a new image created by processing the original image, but it is also possible to process the original image as a processed image without any processing. In other words, when an event requesting the original image occurs, the processor 130 may store the raw image as it is in the memory or transmit it through the communication unit 110 .

The processor 130 may generate a processed image by capturing a still image using the original image received from the camera or generating a moving image in a format required by an event.

The processor 130 may store the generated processed image in a memory provided in the vehicle, transmit it to an external device having a predetermined address, or transmit it to an electronic device in the vehicle according to a method required by an event.

Next, when a second event occurs while generating the first processed image, the processor 130 generates a second processed image by using the original image (S250).

The camera generates one original image, but the processor 130 simultaneously generates different processed images using the original image. For example, a first processed image corresponding to the first event and a second processed image corresponding to the second event may be simultaneously generated from the original image.

The camera control apparatus 100 may simultaneously support different functions using one camera.

The camera control apparatus 100 according to the present invention may control the number of simultaneously generated processed images. A method of adjusting the number will be described in detail with reference to FIG. 3 .

3 is a flowchart for explaining a method of simultaneously generating n processed images.

The processor 130 may update the event list in response to the occurrence of the event (S310).

When a new event occurs, a new event is added to the event list, and when generation of a processed image corresponding to the existing event is finished, the existing event is deleted from the event list. The event list is added in the order in which events occur, and deleted in the order in which the creation of processed images corresponding to the event is terminated.

For example, when a second event occurs after the first event occurs, the first event is added first to the event list and the second event is added in the following order of the first event. Then, when the third event occurs, the third event is added in the following order of the second event.

Next, a natural number n is determined according to a preset condition (S330).

The processor 130 determines n as the number of processed images to be simultaneously generated. n is a natural number. The n may vary according to a preset condition.

For example, the processor 130 may adjust the n based on the data amount of the processed images being generated. Specifically, the processor 130 may measure the data amount of processed images generated per unit time, and determine the n based on the measured data amount. As the amount of data per unit time increases, n may decrease.

As another example, the processor 130 may adjust the n based on the usage amount of the processor 130 . As the usage of the processor 130 increases, the n may decrease.

The reason for adjusting n according to the amount of data per unit time or the usage of the processor 130 is to adjust the load of the processor 130 and/or the load of the communication unit 110 .

As another example, the processor 130 may adjust the n based on a storage space of a memory set to store the processed image. The processor 130 may monitor the storable space of the memory and change the n according to the storable space. The processor 130 may wait for the available storage space of the memory to be secured while adjusting the n. This is to prevent data stored in the memory from being deleted by new data.

Next, n processed images are simultaneously generated according to the order registered in the event list (S350).

For example, when n is determined to be 3 in a state in which three events are registered in the event list, three processed images are generated.

Thereafter, when n is changed to 2, two processed images corresponding to the first event and the second event registered in the list are generated, but generation of the processed image corresponding to the third event is limited. That is, the processed image corresponding to the third event is not generated and is placed in a standby state.

Thereafter, when the generation of the processed image corresponding to the first event is finished, the generation of the processed image corresponding to the third event placed in the standby state is started. Accordingly, two processed images corresponding to the second event and the third event are generated.

4A, 4B, and 4C are conceptual diagrams for explaining an operation of a camera control apparatus.

The camera control apparatus 100 receives one or more original images from a plurality of cameras provided in the vehicle. The configuration for receiving the original image is the communication unit 110 and may be referred to as an 'input unit'.

The processor 130 may include a distribution unit and an implementation unit.

The song distribution unit receives the original image through the input unit, and generates a processed or converted image of the original image in software according to the request of the implementation unit.

The implementation unit executes a function corresponding to the event by using the processed image generated by the distribution unit. For example, a still image obtained by capturing the original image may be stored in the memory, a moving image obtained by recording the original image may be stored in the memory, or the processed image may be encoded and transmitted to a predetermined server through an antenna.

The implementation unit may update the event list and determine the n. The distribution unit may selectively generate the processed image according to the operation of the implementation unit.

The implementation unit may include a first image processing unit that wirelessly transmits the processed image to an external device and a second image processing unit that stores the processed image in a memory mounted on the vehicle.

The first image processing unit is connected to an antenna to wirelessly transmit the generated processed image to an external device. The second image processing unit is connected to a memory to store the generated processed image in the memory.

The processor 130 may allocate the generation of the processed image to the first image processing unit or the second image processing unit according to an event.

As shown in FIG. 4A , when a video storage function (or a first event) for the first to third cameras is executed, the distribution unit includes three original images received from the first to third cameras. are processed according to a method and/or method required by the first event, and the implementation unit may store the three processed images generated by the distribution unit in a memory.

Thereafter, as shown in FIG. 4B , a snapshot storage function (or a second event) for the first and third cameras may be executed. The distribution unit may generate processed images corresponding to the first event and simultaneously generate processed images corresponding to the second event. In this case, although there are three cameras, a total of five processed images are generated, and the five processed images are stored in the memory by the implementation unit.

Thereafter, as shown in FIG. 4C , a transmission function (or a third event) for the first and second cameras may be executed. The distribution unit may generate a total of 7 processed images by using the 3 original images, and the implementation unit may store the 7 processed images in a memory according to each event or transmit it to a server through an antenna.

5 is a flowchart illustrating a method of selecting a camera.

The processor 130 receives a message requesting a predetermined image (S510).

The message is received through the communication unit 110 and may be received as the vehicle driving information described above in FIG. 1 . The processor 130 may determine whether the vehicle driving information corresponds to a preset message, and may generate a processed image corresponding to the preset message.

Next, at least one of the cameras is selected based on the message (S530).

The processor 130 selects at least one camera to generate the predetermined image requested by the message. For example, when a rear view image is requested by the parking assistance system, a rear view camera installed at the rear of the vehicle may be selected. For another example, when an image outside the vehicle is requested from the around-view monitor (AVM), cameras installed in the front, rear, left and right rooms of the vehicle may be selected. The selected camera is changed according to the message.

The processor 130 controls the communication unit to receive an image from the selected camera (S550).

The processor 130 may classify the cameras provided in the vehicle into a first group and a second group based on the message. The first group may include a camera selected by the message, and the second group may include a camera not selected by the message.

The processor 130 may control the communication unit 110 so that the first group of cameras are turned on and the second group of cameras are turned off. This is to prevent unnecessary power consumption by turning on the camera. A camera that is turned off may vary according to a message received from the camera control device.

6 is a flowchart for explaining a method of determining whether to simultaneously generate processed images.

The processor 130 may determine whether the image requested by the second event is the same as the first processed image according to a reference condition (S610).

For example, the reference condition may be defined by at least one of a transmission rate, a resolution, an address to be transmitted, a frame rate, and image scaling.

This is because, when the second event requires the same image as the first event, it is not necessary to duplicate the same processed image. The processor 130 may use the already generated first processed image for first and second events.

As another example, when the name of the image requested by the second event and the name of the first processed image are the same, the processor 130 determines that the image requested by the second event and the first processed image are the same You may.

When the image requested by the second event is the same as the first processed image, the processor 130 may limit the generation of the second processed image (S630).

In this case, the processor 130 continuously generates the first processed image and does not generate the second processed image. The processor 130 outputs an error message for the second event.

When the image requested by the second event is not the same as the first processed image, the processor 130 may generate the second processed image (S650).

Since the processed image is generated only when the images required by different events are not identical after first determining whether the images are the same, unnecessary resources are prevented from being wasted due to unnecessary duplicate creation of the same image.

The present invention described above can be implemented as computer-readable code (or application or software) on a medium in which a program is recorded. The above-described method for controlling the autonomous vehicle may be realized by a code stored in a memory or the like.

The computer-readable medium includes all types of recording devices in which data readable by a computer system is stored. Examples of computer-readable media include Hard Disk Drive (HDD), Solid State Disk (SSD), Silicon Disk Drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. There is also a carrier wave (eg, transmission over the Internet) that is implemented in the form of. In addition, the computer may include a processor or a control unit. Accordingly, the above detailed description should not be construed as restrictive in all respects but as exemplary.
