OpenMV H7 플러스 카메라 -오픈 머신 비전 개발 플랫폼
(OpenMV Cam H7 Plus)
개요
- 본 제품은 OpenMV H7 플러스 카메라 모듈입니다.
- 머신 비전을 쉽게 구현할 수 있게 한 작고 저전력 마이크로컨트롤러 보드입니다.
- 이미지를 캡쳐할 수 있을 뿐아니라 얼굴을 검출하거나 컬러를 트래킹, QR 코드 읽기 등등의 태스크를 수행할 수 있습니다.
- 본 제품은 파이썬 스크립트를 이용하여 프로그래밍이 가능하여 복잡한 머신비전 알고리즘 출력을 쉽게 다루고, 좀더 하이레벨의 데이터 구조로 작업을 할 수 있게 합니다.
- 외부 이벤트를 이용하여 쉽게 사진을 찍거나 비디오를 찍을 수 있으며, IO 핀 제어를 위한 머신비전 알고리즘을 실행할 수 있습니다
- OV5640 이미지 센서를 장착하여 2592x1944 (5MP) 이미지를 찍을 수 있습니다.
- 플러스버전은 카메라를 글로벌셔터 카메라나 FLIR Leption 센서 등으로 교체할 수 있게 디자인되어 있습니다.
- 알림: 핀헤더는 포함되어 있지 않습니다.
특징
- The STM32H743II ARM Cortex M7 processor running at 480 MHz with 32MBs SDRAM + 1MB of SRAM and 32 MB of external flash + 2 MB of internal flash. All I/O pins output 3.3V and are 5V tolerant. The processor has the following I/O interfaces:
- A full speed USB (12Mbs) interface to your computer. Your OpenMV Cam will appear as a Virtual COM Port and a USB Flash Drive when plugged in.
- A μSD Card socket capable of 100Mbs reads/writes which allows your OpenMV Cam to take pictures and easily pull machine vision assets off of the μSD card.
- A SPI bus that can run up to 80Mbs allowing you to easily stream image data off the system to either the LCD Shield, the WiFi Shield, or another microcontroller.
- An I2C Bus (up to 1Mb/s), CAN Bus (up to 1Mb/s), and an Asynchronous Serial Bus (TX/RX, up to 7.5Mb/s) for interfacing with other microcontrollers and sensors.
- A 12-bit ADC and a 12-bit DAC.
- Two I/O pins for servo control.
- Interrupts and PWM on all I/O pins (there are 10 I/O pins on the board).
- And, an RGB LED and two high power 850nm IR LEDs.
- 32 MB of external 32-bit SDRAM clocked at 100 MHz for 400 MB/s of bandwidth.
- 32 MB of external quadspi flash clocked at 100 MHz in 4-bit DDR mode for 100 MB/s of bandwidth (read speed).
- A removable camera module system allowing the OpenMV Cam H7 to interface with different sensors:
- The OpenMV Cam H7 Plus comes with a OV5640 image sensor is capable of taking 2592x1944 (5MP) images. Most simple algorithms will run between 25-50 FPS on QVGA (320x240) resolutions and below. Your image sensor comes with a 2.8mm lens on a standard M12 lens mount. If you want to use more specialized lenses with your image sensor you can easily buy and attach them yourself.
- For professional machine vision applications you can buy our Global Shutter Camera Module.
- For thermal machine vision applications you can buy our FLIR Lepton Adapter Module.
- A LiPo battery connector compatible with 3.7V LiPo batteries commonly sold online for hobbyist robotic applications.
