Jetson Nano——使用JetCam官方库调用双CSI摄像头

环境准备

参考官方配置方案：

git clone https://github.com/NVIDIA-AI-IOT/jetcam
cd jetcam
sudo python3 setup.py install

即可完成库的下载和安装。

报错No nodule named ‘traitlets’

若遇到该报错：

pip3 install traitlets

安装该包即可。

CSI摄像头测试代码

若只有一个CSI摄像头，将camera1相关的代码注释掉即可。

from jetcam.csi_camera import CSICamera
import cv2

camera0 = CSICamera(capture_device=0, width=224, height=224)
camera1 = CSICamera(capture_device=1, width=224, height=224)
image0 = camera0.read()
print(image0.shape)
image1 = camera1.read()
print(image1.shape)
print(camera0.value.shape)
print(camera1.value.shape)
while 1:
    image0 = camera0.read()
    image1 = camera1.read()
    cv2.imshow("CSI Camera0", image0)
    cv2.imshow("CSI Camera1", image1)
    kk = cv2.waitKey(1)
    if kk == ord('q'):  # 按下 q 键，退出
        break

成功运行即可。
