Test with Jetson Nano

Hardware connection

• Insert the camera cable with the metal side facing the heatsink into the camera port on the Jetson Nano development kit.
  • Start the Jetson Nano.
• Test camera.
  • Open the terminal (press Ctrl+ALT+T shortcut on the keyboard to open the terminal), enter the following command to test the camera.

DISPLAY=:0.0 nvgstcapture-1.0

• Test the dual camera.
  • If you need to test dual cameras, you can add sensor-id=x to select the camera. x can be 0 or 1.

#test video0
DISPLAY=:0.0 nvgstcapture-1.0 --sensor-id=0
#test video1
DISPLAY=:0.0 nvgstcapture-1.0 --sensor-id=1

• If the camera shooting effect is reddish, you can follow the steps below:

1. Download the camera-override.isp file and extract it to a specific folder:

wget https://www.waveshare.com/w/upload/e/eb/Camera_overrides.tar.gz
tar zxvf Camera_overrides.tar.gz 
sudo cp camera_overrides.isp /var/nvidia/nvcam/settings/

2.2. Installation files:

sudo chmod 664 /var/nvidia/nvcam/settings/camera_overrides.isp
sudo chown root:root /var/nvidia/nvcam/settings/camera_overrides.isp

【Notice】
- 12 of NV12 is a number not a letter.

- The test screen is output to HDMI or DP screen, so when testing, first connect the screen to Jetson Nano.

• Opencv calls the camera

If you want to use the opencv library to call the camera, you can refer to the official jetcam program
