▌前言

Hello，大家好，这里是OAK中国，我是助手君。

本教程将以OAK-FFC-4P为例，讲解如何从硬件到软件去使用分体式的OAK相机

▌硬件连接

连接相机

OAK-FFC-4P共有四个相机接口，不同接口对应的名称如图。

注意相机接口的触点方向，图中OV9282镜头模组接口触点在下方。

连接时注意要将黄色的软排线的触点接触连接器的触点。
教程

连接设备

按照下图接入5V电源线和Type C线。

▌运行示例

克隆代码

git clone https://gitee.com/oakchina/depthai-python.git

选择分支

cd depthai-python
git checkout multi_cam_support

下载依赖

python3 examples\install_requirements.py

查看示例帮助

python3 tests/cam_test.py -h

usage: cam_test.py [-h] [-cams CAMERAS [CAMERAS ...]] [-mres {480,800,400,720}] [-cres {800,5mp,12mp,48mp,4k,1080,1200,720}] [-rot [{mono,rgb,all}]] [-fps FPS] [-ds ISP_DOWNSCALE]
                   [-rs]

optional arguments:
  -h, --help            show this help message and exit
  -cams CAMERAS [CAMERAS ...], --cameras CAMERAS [CAMERAS ...]
                        Which camera sockets to enable, and type: c[olor] / m[ono]. E.g: -cams rgb,m right,c . Default: rgb,c left,m right,m camd,c
  -mres {480,800,400,720}, --mono-resolution {480,800,400,720}
                        Select mono camera resolution (height). Default: 800
  -cres {800,5mp,12mp,48mp,4k,1080,1200,720}, --color-resolution {800,5mp,12mp,48mp,4k,1080,1200,720}
                        Select color camera resolution / height. Default: 1080
  -rot [{mono,rgb,all}], --rotate [{mono,rgb,all}]
                        Which cameras to rotate 180 degrees. All if not filtered
  -fps FPS, --fps FPS   FPS to set for all cameras
  -ds ISP_DOWNSCALE, --isp-downscale ISP_DOWNSCALE
                        Downscale the ISP output by this factor
  -rs, --resizable-windows
                        Make OpenCV windows resizable. Note: may introduce some artifacts

运行代码（四目OV9282 mono）

python3 tests/cam_test.py -mres 400 -cams rgb,m left,m right,m camd,m

四目IMX477 color

python3 tests/cam_test.py -rs -cams rgb,c left,c right,c camd,c

双目IMX477 color 双目OV9282 mono

python3 tests/cam_test.py -rs -cams rgb,c left,m right,m camd,c
