도 3은 본 발명의 다른 실시예에 따른 영상 획득 방법의 설명에 제공되는 흐름도이다.3 is a flowchart provided to explain an image acquisition method according to another embodiment of the present invention.
이하에서는 도면을 참조하여 본 발명을 보다 상세하게 설명한다.Hereinafter, with reference to the drawings will be described the present invention in more detail.
도 2는 본 발명의 일 실시예에 따른 영상 획득 장치의 블럭도이다. 본 발명의 실시예에 따른 영상 획득 장치는, 적어도 하나의 카메라로부터 영상을 수신하여 서버(300)에 전달한다.2 is a block diagram of an image capturing apparatus according to an embodiment of the present invention. The image capturing apparatus according to the embodiment of the present invention receives an image from at least one camera and transmits the image to the server 300.
이와 동시에, 본 발명의 실시예에 따른 영상 획득 장치는, 프리뷰 생성기(또는, 그 밖의 다른 하드웨어나 소프트웨어)가 생성한 프리뷰를 수신하여 서버(300)에 전달한다.At the same time, the image capturing apparatus according to the embodiment of the present invention receives the preview generated by the preview generator (or other hardware or software) and transmits it to the server 300.
이와 같은 기능을 수행하는 본 발명의 실시예에 따른 영상 획득 장치는, 도 2에 도시된 바와 같이, 압축/프리뷰 제어기(110), 외부 메모리 제어기(120), PCIe 제어기(130) 및 외부 메모리(200)를 포함한다.As shown in FIG. 2, the image acquisition device according to the embodiment of the present invention that performs such a function includes a compression / preview controller 110, an external memory controller 120, a PCIe controller 130, and an external memory ( 200).
압축/프리뷰 제어기(110)는 카메라로부터 입력되는 영상 데이터를 압축하여 압축 데이터를 생성하고, 생성된 압축 데이터를 외부 메모리 제어기(120)를 통해 외부 메모리(200)에 저장한다.The compression / preview controller 110 compresses the image data input from the camera to generate compressed data, and stores the generated compressed data in the external memory 200 through the external memory controller 120.
영상에 따라 압축률이 다를 수 있기 때문에, 압축 데이터를 저장하기 위한 영역은 카메라 및 코덱(채널)마다 별도로 할당한다. 이는, 도 2에 도시된 외부 메모리(200)의 구조를 통해 확인할 수 있다.Since the compression rate may vary depending on the image, an area for storing compressed data is separately allocated for each camera and codec (channel). This can be confirmed through the structure of the external memory 200 shown in FIG. 2.
또한, 데이터를 읽기와 데이터 쓰기에 충돌이 발생하지 않도록 채널 마다 두 개의 영역을 분리하여, 읽기와 쓰기를 분리한다. 이 역시, 도 2에 도시된 외부 메모리(200)의 구조를 통해 확인할 수 있다.In addition, two areas are separated for each channel so that there is no conflict between reading and writing data, and reading and writing are separated. This may also be confirmed through the structure of the external memory 200 shown in FIG. 2.
한편, 압축/프리뷰 제어기(110)는 인터럽트 발생기(111)와 프리뷰 영상 제어기(112)를 구비하고 있다.Meanwhile, the compression / preview controller 110 includes an interrupt generator 111 and a preview image controller 112.
인터럽트 발생기(111)는 외부 메모리(200)에 저장된 압축 데이터가 일정 크기가 되면 인터럽트를 발생시킨다. 그러면, PCIe 제어기(130)에 구비된 인터럽트 제어기(131)가 인터럽트를 서버(300)에 전달한다. 이에, 서버(300)는 압축 데이터를 획득해 간다.The interrupt generator 111 generates an interrupt when the compressed data stored in the external memory 200 reaches a predetermined size. Then, the interrupt controller 131 provided in the PCIe controller 130 transmits the interrupt to the server 300. Accordingly, the server 300 obtains compressed data.
프리뷰 영상 제어기(112)는 프리뷰 영상 데이터를 외부 메모리(200)에 저장함과 동시에, 프리뷰 영상 데이터가 저장된 외부 메모리(200)의 영역(프리뷰 영상 영역)에 대한 주소를 PCIe 제어기(130)의 레지스터(132)에 기록한다.The preview image controller 112 stores the preview image data in the external memory 200 and at the same time registers an address of the region (preview image region) of the external memory 200 in which the preview image data is stored. 132).
이에, 서버(300)는 레지스터(132)에 기록된 주소를 참조하여, 프리뷰 영상 데이터를 획득해 간다. 이때, 프리뷰 영상 제어기(112)는 인터럽트 발생기(111)에 의한 인터럽트 발생을 홀드시킨다.Accordingly, the server 300 obtains the preview image data by referring to the address recorded in the register 132. At this time, the preview image controller 112 holds the interrupt generation by the interrupt generator 111.
압축 데이터가 외부 메모리(200)에서 읽어져 PCIe 제어기(130)를 통해 서버(300)로 전달되는 과정에서, 프리뷰 영상이 유실되는 것을 방지하여 서버(300)에 끊김 없이 전달하기 위함이다.The compressed data is read from the external memory 200 and transferred to the server 300 through the PCIe controller 130 to prevent the preview image from being lost and deliver the data to the server 300 without interruption.
한편, 프리뷰 영상은, 영상 보다 프레임 사이즈를 작게 하는 것이 좋다. 만약, 프리뷰 영상의 프레임 사이즈를 영상과 동일하게 하여야 한다면, 프리뷰 영상의 프레임 레이트를 영상 보다 작게 하는 것이 좋다.On the other hand, it is preferable that the preview video has a smaller frame size than the video. If the frame size of the preview video should be the same as the video, it is preferable to make the frame rate of the preview video smaller than the video.
외부 메모리 제어기(120)는 외부 메모리(200)에 데이터를 읽고 쓰기 위한 수단이며, 외부 메모리(200)에는 영상 데이터, 압축 데이터 및 프리뷰 영상 데이터가 영역 별로 구분되어 저장된다.The external memory controller 120 is a means for reading and writing data in the external memory 200. The external memory 200 stores image data, compressed data, and preview image data by area.
한편, 프리뷰 영상 데이터는 채널마다 동일한 크기와 속도로 입력되기 때문에, 압축 데이터와 같이 채널 별로 분리하여 저장하지 않고, 하나의 영역에 정해진 순서대로 저장하여도 무방하다.On the other hand, since the preview image data is input at the same size and speed for each channel, the preview image data may be stored in a predetermined order in one region instead of being separately stored for each channel like compressed data.
PCIe 제어기(130)는 외부 메모리(200)에 저장된 압축 데이터와 프리뷰 영상 데이터를 서버(300)에 전달하는 인터페이스이다.The PCIe controller 130 is an interface for transmitting the compressed data and the preview image data stored in the external memory 200 to the server 300.
이하에서, 도 2에 도시된 영상 획득 장치에 의해, 영상과 프리뷰 영상이 서버(300)로 전달되는 과정에 대해, 도 3을 참조하여 상세히 설명한다. 도 3은 본 발명의 다른 실시예에 따른 영상 획득 방법의 설명에 제공되는 흐름도이다.Hereinafter, a process of transmitting an image and a preview image to the server 300 by the image capturing apparatus illustrated in FIG. 2 will be described in detail with reference to FIG. 3. 3 is a flowchart provided to explain an image acquisition method according to another embodiment of the present invention.
도 3에 도시된 바와 같이, 초기화 이후에(S210), 서버(300)가 PCIe 제어기(130)의 레지스터(132)에 기록된 주소를 참조하여, 외부 메모리(200)에 저장된 프리뷰 영상 데이터를 획득한다(S220).As shown in FIG. 3, after initialization (S210), the server 300 obtains the preview image data stored in the external memory 200 by referring to the address recorded in the register 132 of the PCIe controller 130. (S220).
프리뷰 영상 데이터는, 외부 메모리(200)의 프리뷰 영상 영역에 저장되어 있으며, 프리뷰 영상의 프레임 사이즈 및/또는 프레임 레이트는 영상의 프레임 사이즈 및/또는 프레임 레이트 보다 작도록 구현함이 좋다.The preview image data is stored in the preview image area of the external memory 200, and the frame size and / or frame rate of the preview image may be smaller than the frame size and / or frame rate of the image.
한편, S220단계에서의 프리뷰 영상 획득을 위해, 서버(300)는 일정 시간 단위로 폴링 한다.On the other hand, in order to acquire the preview image in step S220, the server 300 polls by a predetermined time unit.
그리고, S220단계가 수행되는 중에는, 프리뷰 영상 제어기(112)가 인터럽트 발생기(111)에 의한 인터럽트 발생을 홀드시킨다. 압축 데이터가 외부 메모리(200)에서 읽어져 PCIe 제어기(130)를 통해 서버(300)로 전달됨으로 인해, 프리뷰 영상이 유실되는 것을 방지하기 위한 것이다.In operation S220, the preview image controller 112 holds the interrupt generated by the interrupt generator 111. Since the compressed data is read from the external memory 200 and transferred to the server 300 through the PCIe controller 130, the preview image is prevented from being lost.
S220단계 이후, 서버(300)는 대기하면서(S230), 인터럽트 발생 여부를 확인한다(S240).After step S220, the server 300 waits (S230), and checks whether an interrupt occurs (S240).
인터럽트는 인터럽트 발생기(111)에 의해 발생되어, PCIe 제어기(130)의 인터럽트 제어기(131)에 의해 서버(300)에 전달되며, 외부 메모리(200)에 저장된 압축 데이터가 일정 크기가 된 경우에 발생된다.The interrupt is generated by the interrupt generator 111 and is transmitted to the server 300 by the interrupt controller 131 of the PCIe controller 130, and occurs when the compressed data stored in the external memory 200 becomes a predetermined size. do.
인터럽트가 발생되지 않았으면(S240-N), 서버(300)는 S220단계로 회기하고, 레지스터(132)에 주소가 기록되어 있으면, 기록된 주소를 참조하여 외부 메모리(200)에 저장된 프리뷰 영상 데이터를 획득한다(S220).If no interruption is generated (S240-N), the server 300 returns to step S220, and if an address is recorded in the register 132, the preview image data stored in the external memory 200 with reference to the recorded address. Obtain (S220).
한편, 인터럽트가 발생되면(S240-Y), 서버(300)는 인터럽트를 처리, 즉, 외부 메모리(200)에 저장된 압축 데이터를 획득한다(S250).On the other hand, when an interrupt occurs (S240-Y), the server 300 processes the interrupt, that is, obtains the compressed data stored in the external memory 200 (S250).
