1 is a view for explaining the configuration of a vehicle image processing apparatus according to an embodiment of the present invention.

The vehicle image processing apparatus 100 is also referred to as a vehicle black box apparatus.

Referring to FIG. 1, the vehicle image processing apparatus includes a camera module 101, a microphone 102, a signal processing unit 103, a storage unit 104, a communication unit 105, a power supply unit 106, a control unit 107, It may include an impact detection unit 108, a location information module 109, a display 110, an audio output module 111, an external display device 112, an interface 113, and an input unit 120.

The camera module 101 may capture an image of the front or rear, side, or interior of the vehicle and transmit it to the signal processing unit 103. The captured image may be stored in the storage unit 104 after the compression process in the signal processing unit 103 or directly in the storage unit 104 without a compression process. The camera module 101 is composed of one camera according to the system configuration, and only the front is photographed, or when the camera is composed of a plurality of cameras, the camera's recording position can be variously used in various ways depending on the purpose of use such as front, rear, side, and inside the vehicle You can set

The microphone 102 may record the voice or sound inside or outside the vehicle and transmit it to the signal processing unit 103. The recorded voice or sound may be transmitted to the signal processing unit 103 and passed through a compression process, and then stored in the storage unit 104 or directly stored in the storage unit 104 without a compression process. The recorded voice or sound is related to a sound caused by an external shock or a situation inside / outside a vehicle, and may help to recognize the situation at the time along with the video.

The signal processing unit 103 compresses to reduce the capacity of image data captured from the camera module 101. Image data has the form that each frame is gathered several times on the axis. That is, it can be regarded as a photograph taken continuously for a given time. Since the capacity of such an image is very large when it is not compressed, and it is very inefficient when it is stored in the memory as it is, compression must be performed on the digitally converted image. In video compression, correlation between frames, spatial correlation, and methods using visual characteristics sensitive to low-frequency components are used. Since the original data is lost due to compression, it must be compressed at an appropriate rate to identify the traffic accident situation of the vehicle. As a video compression method, one of various video codecs such as H.264, MPEG4, H.263, and H.265 / HEVC can be used, and video data is compressed in a manner supported by the vehicle image processing apparatus 100.

Also, the signal processing unit 103 may compress data recorded from the microphone 102. The signal processing unit 103 may not only compress the recorded video and audio data, but also encrypt them to restrict access to the data.

The storage unit 104 may store the video and audio data in a single file or two files in units of storage cycles by storing the recorded video and audio data. For example, if the storage period is 30 seconds, the video and audio recorded for the first 30 seconds are compressed and stored in the form of a video file, and the recorded video and audio for 30 seconds are repeatedly compressed and stored.

The storage unit 104 may divide and store different data according to a recording mode. For example, the data recorded during driving and the data recorded during parking may be stored in a separate folder, and the always-recorded data and data recorded by an event may be stored in a separate folder.

The storage unit 104 may be configured inside the vehicle image processing apparatus 100 or configured detachably through a port provided in the vehicle image processing apparatus 100 or may exist outside the vehicle image processing apparatus 100. When the storage unit 104 is configured inside the vehicle image processing apparatus 100, it may exist in the form of a hard disk drive or a flash memory.

The shock detection unit 108 may include an acceleration sensor, a geomagnetic sensor, and the like to detect shock or acceleration.

The location information module 109 is a module for confirming or obtaining the location of the vehicle image processing apparatus 100. A representative example of the location information module is a Global Position System (GPS) module.

The location information module 109 continuously calculates the current location of the vehicle in real time and uses it to calculate the vehicle's speed information.

The display 110 displays and outputs information processed by the vehicle image processing apparatus 100.

For example, the display 110 can display the video and audio recorded by the camera module 101 in real time or later, and display them on the screen to facilitate recording setting in the control unit 107 and touch them. Input is possible, so the user can easily select and set the desired function.

The display 110 includes a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, and a three-dimensional display ( 3D display).

When the display unit 110 and a sensor detecting a touch operation (hereinafter referred to as a “touch sensor”) form a mutual layer structure (hereinafter, abbreviated as “touch screen”), the display unit 110 is an output device. In addition, it can be used as an input device. The touch sensor may have a form of, for example, a touch film, a touch sheet, or a touch pad.

2 is a block diagram of an image processing system for a vehicle according to an embodiment of the present invention.

Referring to FIG. 2, a vehicle image processing system according to the present invention may be configured to include a vehicle image processing apparatus 100 mounted on a vehicle and a power supply unit 200 that supplies power to the vehicle image processing apparatus 100. have.

The ADC 130 of the vehicle image processing apparatus 100 converts the analog power value input from the power supply unit 200 to digital, and the control unit 107 analyzes the digitally converted power supply value, and the vehicle image processing apparatus 100 Set the operation mode.

 The ADC 130 may check the voltage of a vehicle battery power source or a dedicated power source of the vehicle image processing apparatus 100.

The control unit 107 may check the capacity of the vehicle battery from vehicle information or by a user input. In the case of a passenger car, the capacity of the battery is about 40 Ah to 100 Ah, which can be variously configured depending on the vehicle. As the battery of a vehicle varies, the amount of current continuously consumed by the vehicle itself while the engine is turned off also varies. Therefore, in order to check the exact remaining battery capacity, the battery capacity and the power consumed by the vehicle itself can be checked to accurately calculate the remaining battery capacity that can be consumed by the vehicle image processing apparatus 100 during parking.

The controller 107 may learn the discharge curve of the vehicle battery for a certain period of time or use the discharge curve set for each model and capacity of the battery to calculate the expected remaining battery power until the battery power-off voltage.

For accurate setting of the vehicle battery discharge log, the vehicle's battery information may be input at the time of installation of a black box (an example of the vehicle image processing apparatus 100) or at the request of a user.

Since there is a difference in the voltage that is completely discharged according to the state and capacity of the vehicle battery, the cut-off voltage of the battery, which blocks the operation of the vehicle image processing apparatus 100, is between 11.4V and 12V depending on the state or capacity of the battery. Allow the control unit 107 to set.

Here, the cut-off voltage is a time when the vehicle image processing apparatus 100 is turned off to prevent a complete discharge of the vehicle battery.

When the vehicle start is turned on, the vehicle's generator is operated, so it is not possible to measure the exact voltage of the battery, so the vehicle's image processing device 100 starts using the vehicle's ACC signal or detects a sudden drop in battery power. Upon recognizing that it is off, it begins to log the battery discharge to learn the battery discharge curve.

The battery discharge record reads the log value once every 3 to 5 seconds, and the log data value can also be stored in an external ROM. For example, when the voltage of the vehicle battery is about 12.3V or more, recording of video and audio, which is a normal black box function, and when the voltage of the vehicle battery falls below 12.2V, the vehicle battery voltage is low to the user. Recognize the sound and lower the resolution and frame rate of the video.

In the parking mode, when the voltage of the vehicle battery becomes 12.1V, it is possible to increase an amount of time to record an image by recording only when an event due to an object movement or an impact occurs without recording the image in real time.

At this time, it is possible to inform the driver that the vehicle battery is low through an external display device of the vehicle image processing apparatus 100, so that the vehicle image processing apparatus 100 can be prevented from being operated due to discharge of the battery.

By checking the stored battery discharge logo, if the discharge curve period becomes shorter as time elapses, a function of notifying the driver that it is time to replace the battery may be performed.

The control unit 107 may learn and confirm the time and place at which the vehicle image processing apparatus 100 operates in the parking mode or by user input.

The control unit 107 may set and manage the operation of the parking mode according to the driving record of the vehicle and the surrounding environment.

When the vehicle enters the parking mode, the control unit 107 checks the estimated parking time and the remaining battery capacity, so that the camera operating time, resolution, and frames per second are operated so that the image processing device 100 for the vehicle can operate during the expected parking time. Set to operate the vehicle image processing apparatus 100 in the parking mode.

The control unit 107 may learn the driving time zone of the vehicle on a weekly, monthly, or yearly basis based on the actual driving record of the vehicle, and predict parking time until the next driving time after the driving is finished.

Alternatively, the user can directly enter the driving record of the vehicle and estimate the parking time until the next driving time after the driving is finished. For example, if the vehicle stops running at the garage where the vehicle is registered at 7 PM on Friday, and then parks the vehicle at 8 AM on Monday, maintaining the parking state during that time is January's driving record. If you park at a location that falls on the Friday evening in January, you can estimate the parking time by expecting to park for the time until next Monday morning.

The control unit 107 may request the user to input the parking time until the next driving time by requesting the user in the step in which the vehicle is turned off, to check the estimated parking time.

3 is a flowchart of a power management method according to a first embodiment of the present invention. The power management method according to the first embodiment of the present invention may be implemented in the vehicle image processing apparatus 100 and the vehicle image processing system described with reference to FIGS. 1 and 2. Hereinafter, the power management method according to the first embodiment of the present invention and operations of the vehicle image processing apparatus 100 and the vehicle image processing system for implementing the same will be described in detail with reference to the necessary drawings.

According to the first embodiment of the present invention, the operation of the image processing apparatus 100 for a vehicle may be set and managed according to the driving record of the vehicle and the surrounding environment.

Referring to FIG. 3, the control unit 107 determines whether the vehicle is moving in step S300.

Here, the determination of whether the vehicle is moving is determined by analyzing, by the controller 120, image data collected through an imaging device (not shown) such as CMOS or CCD or location information of the vehicle received through the location information module 109. Can be.

In step 300, if it is determined that the vehicle is driving, the image processing apparatus 100 for a vehicle operates in a normal mode [S330], and when the vehicle is stopped, the vehicle is switched to a parking mode to determine whether the vehicle starts to be turned on [ S310].

At this time, when the vehicle start is turned on, the vehicle image processing apparatus 100 operates in a normal mode [S330], and when the vehicle starts off, the vehicle image processing apparatus 100 operates in a power saving mode [S320] .

<Power saving mode>

4 is a flowchart of a control method of an image processing apparatus for a vehicle according to a second embodiment of the present invention. The control method of the vehicle image processing apparatus according to the second embodiment of the present invention may be implemented in the vehicle image processing apparatus 100 and the vehicle image processing system described with reference to FIGS. 1 and 2.

Hereinafter, a control method of an image processing apparatus for a vehicle according to a second embodiment of the present invention and operations of the image processing apparatus 100 and an image processing system for a vehicle for implementing the same will be described in detail.

Referring to FIG. 4, the control unit 107 first checks the remaining power of the power supply unit 200 supplied to the vehicle image processing apparatus 100 [S600a].

Then, the control unit 107 checks the driving mode and habits of each vehicle driver, which has been previously learned, [S600b], and then calculates the operational time of the vehicle image processing apparatus 100 based on the remaining power of the power supply unit 200 [S600c] In order to operate the vehicle image processing apparatus 100 at an optimal time or at a maximum time, the number of frames of the recorded image is set to operate [S600d].

The vehicle image processing apparatus 100 may operate in different operation modes and power management modes when the vehicle is driving and parking.

For example, if the vehicle is driving (driving mode), regular recording is performed, and when an event such as an impact occurs, event recording is performed. When the vehicle is judged to be parked and the ignition is off (parking mode), recording is performed when an event due to an impact or the movement of an object is detected by the camera.

The control unit 107 may cut off the power of the vehicle image processing apparatus 100 when the power of the battery falls below a certain level when the vehicle is turned off and the power of the vehicle battery is used during parking.

The mode change between the driving mode and the parking mode, which is the operation mode of the vehicle image processing apparatus 100, is converted to the parking mode when there is no movement of the vehicle for a certain period of time, and when the movement of the vehicle is detected, the driving mode may be executed.

In addition, when it is confirmed that the vehicle is started off, the vehicle can be converted into a parking mode and operated. In the parking mode of the vehicle, only power for maintaining the minimum function of the vehicle image processing apparatus 100 may be supplied. When the vehicle is in the parking mode and the ignition is turned off, the power can be cut off at all times and the auxiliary battery can be supplied with power to the vehicle image processing apparatus 100.

The discharge curve of the vehicle's battery can be learned for a certain period of time, or the expected battery level until the battery power-off voltage can be calculated using the discharge curve set for each model and capacity of the battery.

The number of occurrences of events according to the parking time zone, the day of the week, and the parking place can be learned based on the driving record of the vehicle and the location and time of the recorded image stored in the vehicle image processing apparatus 100 or set by user input.

When the vehicle enters the parking mode, it checks the number of events and battery level according to the time zone, the day of the week, and the parking place, and the vehicle image processing device according to the number of events so that the vehicle image processing device 100 can operate during the expected parking time ( 100) can be set differently.

If the battery level of the vehicle is not large, it can be set to operate only during a time when there are many events.

In addition, when the remaining battery power of the vehicle is not large, the number of frames and resolution of the image processing apparatus 100 for a vehicle is increased during a time when there are many events, and the number of frames of a camera 101 of the image processing apparatus 100 for a vehicle is increased during a time when there are few events. You can increase the recording time by lowering and resolution.

Since the operation time of the vehicle image processing apparatus 100 varies according to the capacity of the battery even when the vehicle battery is at the same voltage, when checking the capacity of the battery through vehicle information or by user input and entering the parking mode, the vehicle battery The remaining amount can be calculated accurately.

The voltage level of the battery power may be sensed and displayed on the display 110 of the vehicle image processing apparatus 100 so that the user can easily check the voltage of the vehicle battery.

The voltage level of the battery power may be displayed when a driver's approach is detected to turn on the vehicle or a seat is detected in the driver's seat. You can also display the battery power when you turn off the vehicle.

In addition, when the ignition is turned off, the voltage difference between the voltage level of the battery power and the cutoff level of the battery power is determined, and if the difference is equal to or less than a certain voltage, the vehicle image processing apparatus 100 is immediately turned off without entering the parking mode and the user is turned off. I can tell you.
