Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to or limited by the embodiments. Like reference symbols in the drawings denote like elements.

Hereinafter, an apparatus and method for transmitting image data of a black box using a wired or wireless communication network according to an embodiment of the present invention will be described with reference to the drawings.

Transmitting all the video files stored in the black box puts a heavy load on the communication network, especially in the case of wireless communication network, greatly increases the transmission cost. Accordingly, the present invention proposes a method and a method of extracting an image by extracting and transmitting a portion of the stored image. In certain applications, video recording should continue without interruption even when the image is transmitted, such as a vehicle black box.

The present invention also describes how to transmit the video without interruption of the video recording in this case.

The still image used in the present specification is a concept that collectively refers to image information having no motion in time. Hereinafter, for convenience of understanding, the still image is represented as an image frame which may be a kind of still image. The " still image " is, for example, image data obtained from an image sensor (raw image), an image such as JPEG compressed with the image data, or an I-frame or P- compressed from a codec such as H.264 or MPEG4. The concept may include a frame.

1 is a block diagram of an image data transmission apparatus according to a first embodiment of the present invention.

Referring to FIG. 1, the image data transmission device 110 included in the black box 100 may be output from an image recording unit 101 for recording an image frame into a memory, an event sensor 102 of an acceleration sensor, and a motion detector. The event generating apparatus 103 for receiving an event, a range determination unit 104 for determining a transmission target based on a time point at which an event is input, and an image extraction unit 105 for extracting image frames in a memory storing image frames to be transmitted. And an image transmitter 106 for transmitting the extracted image frames.

In addition, FIG. 1 shows a server 120 for communicating with the image data transmitting apparatus 110 and storing and managing image frames transmitted via wired or wireless, and a terminal 130 for receiving the image frames stored from the server 120. .

First, the image recording unit 101 acquires an image frame captured by the black box 100 as a period arrives by a timer or the like at a preset time, and records the image frame in a memory corresponding to the first time point at which the acquisition is made. do. The first viewpoint may be variable time data that is changed and determined according to acquisition of an image frame. Also, the second time point to be described later may be single time data to which an event related to image frame transmission is input.

3 is an exemplary diagram illustrating a time range corresponding to n first time points having a time interval, a second time point at which an event is input, and a predetermined section according to the present invention.

The image recorder 101 stores the image frame in the memory in consideration of the n first viewpoints having a time interval, and the range determiner 104 determines a transmission target based on the second viewpoint at which the event is input. In FIG. 3, when the second time point at which an event is input is current, the first time point corresponds to 'A-4, A-3, A-2, A-1, A' of the time data for which the video frame is acquired. It may be exemplified as 'A + 1, A + 2, A + 3, A + 4' of time data for which an image frame should be acquired.

When the range determiner 104 determines the time range including at least the second time point as the transmission target, the image extractor 105, when the time range elapses, selects all the products belonging to the time range. Image frames recorded corresponding to one time point are collectively extracted from the memory. That is, the image extractor 105 waits until the last first time point in the time range elapses, and when the image frame is acquired and stored in the memory at the last first time point, the image is extracted from the memory. Image frames of the first view corresponding to the time range are collectively extracted.

As shown in FIG. 3, for example, when 'A-2 to A + 2' is determined as the time range including the second time point, the image extractor 105 acquires an image frame at the last first time point A + 2 within the time range. After waiting to be stored in the memory, the first time point A + 2 or later from the memory, at all first time points A-2, A-1, A, A + 1 and A + 2 belonging to the time range. Correspondingly recorded video frames can be extracted in a batch.

Referring back to FIG. 1, the image recording unit 101 records image frames in memory in time series considering n first viewpoints having a predetermined time interval, but if the recording space is insufficient, the image frames are recorded first. Delete from memory.

The event generating device 103 receives an event generated by the event detecting device 102, namely, an impact sensor, a motion detection sensor, a user manual input, a power cut detector, a speed detector, and the like, and transmits an image frame to be transmitted to the server 120. Set the reference point.

The range determiner 104 determines a transmission target based on a second time point at which an event is input from the event generator 103. The range determination unit 104 determines a time range including at least a second time point as a transmission target.

The image extracting unit 105 identifies a first viewpoint corresponding to the transmission target in the memory and extracts an image frame recorded corresponding to the identified first viewpoint from the memory.

In extracting an image frame from the memory, the image extractor 105 stores an image frame to be transmitted before, after, or before or after an event based on a reference time point, which is a second time point at which an event is input, Find out the location.

The image extractor 105 includes a memory for storing the image frame to be transmitted, and additionally stores the obtained image frame or the image frame received from the black box 100 at a specific interval in the memory.

The size of the memory is determined by the maximum number of video frames to be transmitted and the size of each video frame. For example, if the maximum number of frames of the video frames to be transmitted is 10, and the size of each video frame is 32 KB, At least 320KB will be needed. In addition, the method of storing the image frame into the memory receives the image frame captured by the black box 100 at a specific interval, for example, every second, and stores the image frame in the memory. At this time, if the memory to store the video frame to be transferred is full, the first stored video frame is deleted. The image extraction unit 105 stores the image frame while rotating the storage location continuously unless an event occurs in this manner.

When an event occurs, the image extractor 105 samples the image of the black box 100 at a predetermined interval for a predetermined period and stores it in a memory, and transmits the image frame to the image transmitter 106 after the predetermined period elapses. Ask.

In another embodiment, when the range determiner 104 determines the time interval from the second time point at which the event is input, the image extractor 105 determines that the last time interval of the time interval determined as the transfer target is determined. When the elapsed time has elapsed, a still image recorded corresponding to all the first time points corresponding to the time interval may be collectively extracted from the memory. That is, the image extractor 105 waits to extract the image frame from the memory until the image frame is acquired at all of the n first views (n is a natural number) having a predetermined time interval.

For example, referring to FIG. 3, it is assumed that a predetermined time interval 'A-4, A-2, A, A + 2, A + 4' from the second time point is determined as the transmission target. After waiting for an image frame to be acquired and stored in a memory at a first time point A + 4 which is the last time interval of the time intervals determined as the transmission target, the time frame corresponds to the time interval from the memory after the first time point A + 4. Image frames recorded corresponding to all first viewpoints A-4, A-2, A, A + 2 and A + 4 can be collectively extracted.

In another embodiment, the image extractor 105 may extract the image frame from the memory in real time in association with the image frame being acquired and recorded in the memory at a first time point included in the transmission target. .

The image transmitter 106 transmits the image frames before and after the event stored in the memory to the server 120 including a code for identifying a specific ID or a device corresponding to the black box or the terminal. That is, the image transmitter 106 transmits the extracted image frame through a communication network.

In addition, the image transmitter 106 may select and transmit an image frame in which an image change is detected among the extracted image frames. This is because the image extracting unit 105 stores the image frame at a predetermined interval in the memory. This is because the same image is always captured when there is no change in the external image when the vehicle is parked like a black box for a vehicle. That is, even if the image transmission unit 106 extracts an image frame corresponding to the first point of time belonging to the transmission target, if there is no image change between the extracted image frames, the image transmission unit 106 does not transmit the same image frame unnecessarily. Do not Instead, the image transmitter 106 determines whether the image is changed and selects and transmits an image frame at that time only when there is an image change. The method of detecting an image change includes a method using a conventional motion sensor, for example, a method of mounting a separate motion sensor, a method of determining a difference between a previous video frame and a current video frame.

According to an embodiment, the image change detection for the image frame may be performed before extracting the image frame from the memory. That is, the present invention may be configured such that the image extractor 105 selectively extracts only frames in which image changes in the image frames before and after the event occurs from the memory.

In addition, the image transmission unit 106 distributes the image frame by using at least one of a background technique, a multitasking technique, or a multithreading technique, and transmits the image frame. , Video shooting, video playback, etc.) can be performed smoothly.

The server 120 obtains the black box 100 ID or the terminal phone number with reference to a specific ID or code, stores the image frame received from the identified black box 100, and designates the terminal 130 designated as the ID or phone number. The video frame is transmitted. The server 120 may receive a specific ID or code from the black box 100 or the terminal 130 and manage the received image frame in a database.

The terminal 130 receives a connection request from the server 120, connects a communication session, notifies that the image frame is received from the server 120, receives and stores the image frame, and then the user captures the image captured by the black box 100. Outputs the video frame so that the frame can be seen.

2 is a block diagram of a video data transmission apparatus according to a second embodiment of the present invention.

Referring to FIG. 2, the image data transmission device 220 is connected to the existing black box 210. The black box 210 captures an image in real time through the camera 201 and stores the image in the storage cell 202. The black box 210 outputs an image captured by the image output unit 203 which is an external output terminal.

The image data transmission device 220 receives an image from the image output unit 203 of the black box 210 and stores the image in the image input unit 221. The black box 210 stores the image frames in the storage cell 202 in the order of capturing, and the image extractor 222 of the image data transmission device 220 is identified by a first time point corresponding to the transmission target. The storage cell 202 in the box 210 is accessed to receive an image frame stored in the storage cell 202.

When a time range including at least a second time point at which an event is input is determined as the transmission data, the image data transmitting device 220 determines that the image extractor 222 belongs to the time range when the time range elapses. The image frames, which are stored by accessing the storage cells in the black box, identified by all first viewpoints, are collectively received. That is, the image extractor 222 waits for access to the storage cell 202 until the image frame is stored in the storage cell 202 in the black box 210 identified by the last first time point in the time range. When the image frame is acquired at the last first time point and stored in the storage cell, the storage cell is accessed to receive the image frames at the first time point corresponding to the time range in a batch.

In another embodiment, the image data transmission device 220 is a transmission target, and when a time interval from a second time point at which an event is input is determined, the image extraction unit 222 may perform the time interval determined as the transmission target. When the last time interval elapses, image frames stored and accessed by storing cells in the black box, which are identified by all first time points corresponding to the time interval, are collectively input. That is, the image extractor 222 accesses the storage cell 202 until the image frame is stored in all the storage cells 202 in the black box 210 identified by the n first viewpoints having a time interval. While waiting for, the storage cell identified by all the first time points corresponding to the time interval may be received collectively to receive the stored image frame.

In another embodiment, the image extracting unit 105 may receive the still image in real time by accessing a storage cell in the black box identified by the first time point at a first time point included in the transmission target. Can be.

The image data transmission device 220 extracts an image frame stored in the image input unit 221 based on an event detected by an acceleration sensor or a motion detector, stores the image frame in a rotation queue, and transmits the image frame to the server 230.

The server 230 receives and manages the still images before and after the event, stores them in a database, and provides the images to the terminal 240 so that the user can check the images captured by the black box 210.

4 is an exemplary view showing a configuration of a memory according to an embodiment of the present invention.

4 shows a memory having n image frames. The memory has n predetermined sizes, each frame represents an allocated memory per one image frame, and frame number 3 indicates a current position to store the image frame. For example, when the memory stores 10 image frames, if the memory is 32kb per frame, the memory has a size of 320kb. For example, when image frames are input at intervals of 1 second, the memory sequentially stores image frames every 1 second.

5 is an exemplary diagram illustrating a method of erasing a first stored image when a memory is full according to an embodiment of the present invention.

Referring to FIG. 5, when the memory for storing n image frames is filled up to the n th position and the memory is full, the memory moves the position for storing the image frame to the first position to erase the first stored image. 5 shows that the method is adopted.

The memory sequentially increases the storage position of the image frame and stores the image frame. When the storage position reaches the nth image frame, the memory returns to the first storage position and stores the input image frame. It can be seen that when logically accessed, the memory is in the form of a rotating queue. The memory records the storage position to determine in which position the input image frame is to be stored, and stores the image frame input at the determined position.

FIG. 6 is an exemplary diagram illustrating an embodiment of calculating an image before and after an event to extract an image to be transmitted by the image extractor according to an embodiment of the present invention.

When an event occurs and an event is detected by the event input unit, the image extractor stores a storage location of a memory corresponding to the event detection time and calculates a memory storage location before and after a preset image transmission time reference.

For example, in case of transmitting an image of five image frames when an event occurs, the image extractor calculates a start position before the event occurrence and an end position after the event occurrence based on the image frame storage position in the memory where the event occurs. The memory continues to store video frames after an event occurs. The image extractor extracts five image frames from the memory when the storage position of the image frame reaches the end position.

7 is an exemplary view illustrating a method of tracking a position of an image frame to be transmitted from a memory storing an image by a black box according to an embodiment of the present invention.

Referring to FIG. 7, FIG. 7 illustrates a method in which a black box stores an image frame in an image memory and tracks a position of an image frame to be transmitted from the memory.

When explaining how to use the video frame stored in the memory, the black box waits until the video frame is stored in the nth position and then sends the video frame to the nth position. 2 (nm) +1 image frames in the memory are extracted, acquired and used. The above-described extraction of 2 (nm) +1 video frames is applicable only when the number of video frames to be acquired before and after the event is the same, and the present invention is not limited thereto, and within the technical scope of the present invention, It will be apparent to those skilled in the art that the number of extractions can be calculated flexibly.

8 is an exemplary diagram illustrating a method of calculating a position of an image frame to be extracted in a memory before and after an event occurs by a black box according to an embodiment of the present invention.

Referring to FIG. 8, FIG. 8 illustrates a method in which an event occurs and the black box calculates a position of an image frame to be extracted in a memory before and after an event occurs. For example, in case of transmitting an image of 5 video frames when an event occurs, the image extracting unit starts the position before the event of m-2th video frame and m + 2th based on the image memory location of the mth video frame where the event occurred. Calculate the end position after event of video frame. The memory continues to store video frames after an event occurs. The image extractor extracts five image frames from the memory when the storage position of the input image frame reaches the end position.

9 is a flowchart illustrating an image transmission process according to an embodiment of the present invention.

The image data transmission device stores image frames in a memory at predetermined intervals and stores a current storage location of the memory (801).

When the image data transmission apparatus detects an event occurrence, the start position and the end position are calculated in consideration of the transmission frame, and after the event is generated (802), when the image frame is completely stored up to the calculated end position (803, 804) from the memory. The image corresponding to the transmission frame is extracted (805).

The image data transmission device transmits the image extracted from the memory using a wired or wireless communication network (806). The image data transmission apparatus determines whether the transmission of the image determined as the transmission frame is completed (807) and transmits the image.

The image data transmitting apparatus may divide the image data to be transmitted and transmit it through the communication network in order to continuously store and track the image even when the image is transmitted, even when the image is transmitted (808). To this end, the image data to be transmitted is distributed in an appropriate size, and the image data transmission device is idle for a certain period of time so as to perform other operations such as image recording or image extraction after transmitting the image distributed by the background or multitasking or multithreading technique. (809). The image data transmission device repeats this process until all image frames have been transmitted (810).

The image storage and management server plays a role of storing and managing image data when the image data transmission device transmits an image. To this end, the image data transmission device of the present invention transmits a code for identifying a specific ID or device when accessing a server. The server can identify which of the multiple devices are connected by a specific ID or code, and can also store and store the data transmitted by each device. In addition, even when the terminal accesses the server, a specific ID or code may be transmitted to the server to determine which image data transmission device the server transmits to the terminal.

The terminal may be any terminal capable of wired or wireless communication such as a smartphone or a computer. The terminal may request an image transmission from the server and download the image stored in the server.
