jetson nano tx2 调用csi摄像头(解决摄像头蓝屏问题)

./darknet detector demo cfg/coco.data cfg/yolov3-tiny.cfg yolov3-tiny.weights "nvarguscamerasrc ! video/x-raw(memory:NVMM), width=1280, height=720, format=NV12, framerate=30/1 ! nvvidconv flip-method=2 ! video/x-raw, width=1280, height=720, format=BGRx ! videoconvert ! video/x-raw, format=BGR ! appsink"
           

my nano demo succeful:

./darknet detector demo cfg/coco.data cfg/yolov3-tiny.cfg yolov3-tiny.weights "nvarguscamerasrc ! video/x-raw(memory:NVMM), width=1280, height=720, format=NV12, framerate=30/1 ! nvvidconv  ! video/x-raw, width=1280, height=720, format=BGRx ! videoconvert ! video/x-raw, format=BGR ! appsink"
           

说明:

(nvarguscamerasrc ! video/x-raw(memory:NVMM), width=1280, height=720, format=NV12, framerate=30/1)
           

作用是配置摄像头获取的画面大小和帧数;

官网示例地址

(nvvidconv flip-method=2)
           

作用是旋转画面

官网示例地址

(video/x-raw, width=1280, height=720, format=BGRx ! videoconvert ! video/x-raw, format=BGR)
           

作用是确保来自CSI相机的原始视频转换为BGR色彩空间。

退出

退出时最好采用在显示窗口按下

esc

的方式,也可用
