如何测试摄像头，打开Jetson 设备的终端

输入命令：nvgstcapture-1.0 ，摄像头就会起来了

此方法只能打开一个摄像头,且不容易关闭,非常麻烦.下面介绍使用python代码打开两路csi

摄像头的方法.

1.安装traitlets

首先记得查看自己的python版本，以python3.7为分界线。

python3.7以下用traitlets 4.x；(如未安装pip3,则应该首先安装pip3,安装命令为sudo apt install python3-pip)

pip3 install traitlets==4.3.3

python3.7以上才可以用traitlets 5.x

pip3 install traitlets

traitlets的历史版本https://pypi.org/project/traitlets/#history

2.安装Jetcam

参考官方github的内容https://github.com/NVIDIA-AI-IOT/jetcam

git clone https://github.com/NVIDIA-AI-IOT/jetcam

cd jetcam

sudo python3 setup.py install

3. 编写test.py代码

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

4. 执行该代码 python3 test.py.
