Camarray-Arducam 1MP Stereoscopic Camera Bundle Kit

Specs and Selection Guide for Arducam 1MP Stereoscopic Camera Bundle Kit


​This Arducam stereo camera bundle kit consists of two synched OV9281 global shutter cameras and an Arducam Camarray stereo camera HAT. As a stereo bundle system, it enables simultaneously working dual cameras with a variable baseline for better prototyping and evaluation with a single MIPI CSI camera slot: The two image sensors are on separated camera boards, and you easily move them around for different perspectives while the Camarray HAT handles the rest of the work. This is helpful for proof-of-concept stages when you may want more flexibilities than what a fixed stereo camera module can offer. You will be able to find the optimal baseline for your application with this bundle, and we welcome you to send us product customization requests after that.

What is Camarray

Camarray is a series of embedded stereo cameras and multiple camera solutions from Arducam. Upgraded from Arducam Sync Stereo Camera HAT, the Camarry can disguise up to 4 synched camera modules as a single camera slot connection to embedded systems like the Raspberry Pi, Jetson nano, and Xavier NX. With Arducam camarray, your camera connectivities are no longer limited to the camera connectors on the motherboard or the carrier board. Along with Arducam-provided camera drivers, more flexibility is added to your multi-camera applications.

Same operation on Xavier NX. The only difference is the driver package.

Hardware Setup

b0266 02long
b0265r 07 1

Install the driver

1.Check system version

#Check the L4T version

cat /etc/nv_tegra_release
Check the L4T version
From the example above, its L4T vision is R32 4.3

#Check the kernel version

uname -a
Check the kernel version
From the example above, its kernel vision is 4.9.140

2.Download Arducam driver package

Open the link below:


Depending on the hardware platform and system version currently in use, find the corresponding driver.

Download the driver package1
Download the driver package2
Download the driver package3

Download it and put it under the root directory.

root library

3.Install Arducam driver package

Then type the following command to install the V4L-utils The driver package name (.deb) should be changed according to the actual download.

sudo dpkg -i arducam-nvidia-l4t-kernel_4.9.140-32.4.3-20200716095813_arm64.deb
install driver package

4.Install V4L-utils package

sudo apt-get install v4l-utils
install v4l driver

First Use

1.Install V4L2 python module

for Python3.x:

wget https://bootstrap.pypa.io/get-pip.py  
Install V4L2 python module1

After you type the following command and press【Enter】, it will take several minutes to finish downloading.

sudo python3 get-pip.py  
Install V4L2 python module2
Install V4L2 python module3
 sudo pip3 install v4l2 
Install V4L2 python module4


The V4L2 of Python3.x has a known bug that requires a manual fix, and the following error occurs when you import the v4l2 module into Python3.x:

Install V4L2 python module5

You can refer to this link to fix this bug:


2.Download the demo code

git clone https://github.com/ArduCAM/MIPI_Camera.git  
Download the demo code1
Download the demo code2

3.Check whether the camera is detected

ls /dev/video0
Check whether the camera is detected1

4.Check the video format supported

v4l2-ctl --list-formats-ext

5.Display images in real time

If accessing Jetson via remote software (e.g., MobaXterm), the following command (executed only once) is required to display the image.

export DISPLAY=:0.0

Enter program directory: 

cd Arducam/

OV9281 currently supports the following commands:


python3 arducam_displayer.py -f GREY --width 2560 --height 800 -d 0
python3 arducam_displayer.py -f GREY --width 2560 --height 720 -d 0
python3 arducam_displayer.py -f GREY --width 1280 --height 400 -d 0
python3 arducam_displayer.py -f GREY --width 1280 --height 400 -d 0


python3 arducam_displayer.py -f Y16 --width 2560 --height 800 -d 0
python3 arducam_displayer.py -f Y16 --width 2560 --height 720 -d 0
python3 arducam_displayer.py -f Y16 --width 1280 --height 400 -d 0
python3 arducam_displayer.py -f Y16 --width 640 --height 200 -d 0

​GREY for RAW8 and Y16 for RAW10.

​-w and -h indicate the width and height of the input image.

The command line will refresh the display of frames in real time.


Display resolution settings may affect the frames displayed.

Display the image via VLC media player


The VLC can only play images exported in RAW8 format.

Open VLC media player

VLC media player

1.Display the image

Press Ctrl+C


Video device name】→ select “/dev/video0“→ click 【Play】.


2.Adjust exposure and gain

Press Ctrl+E, drag the sliders at “Exposure” and “Gain” to make adjustments under the “v4l2 control” tab.


Display the image via mplayer

1.Install mplayer

sudo apt-get install mplayer

2.Display images

mplayer tv:// -tv driver=v4l2:device=/dev/video0

Do not enter this command remotely, otherwise it will be stuck.

nano mplayer b0267

Or enter the following command to zoom the image. 

mplayer tv:// -tv driver=v4l2:device=/dev/video0 -zoom -x 1280 -y 400

“-x” “- y” denotes the width and height of the scaled image, and it is recommended to modify them in equal proportion.
