./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。
