INTRODUCTION

• About ArducamArducam has been a professional designer and manufacturer of SPI, MIPI, DVP, and USB cameras since 2012. We also offer customized turnkey de­sign and manufacturing solution services for cus­tomers who want their products to be unique.
• About This Pivariety CameraArducam Pivariety is a Raspberry Pi camera solution to take the advantage of using its hardware ISP functions. Pivariety camera modules make users get better performance and a wider variety of camera, lens options. In other words, Pivariety break­through the limitations of the closed-source official supported camera driver and camera modules (V1/ V2/H Q).

Pivariety camera modules made it possible to be well-tuned ISP with Auto Exposure, Auto White Balance, Auto Gain Control, Lens Shading Correc­tion, etc. This series of cameras use the lib camera framework, they can’t be supported by Raspistill, and the way to access the camera is lib camera SDK (for C++)/lib camera-still/lib camera-vid/Gstreamer.

This Pivariety OGO2B10 Color Global Shutter Cam­era is migrated Raspberry Pi Cameras, which elimi­nate rolling shutter artifacts to shoot high-speed moving objects in color sharp images.

SOFTWARE

1. Driver Installationwget -O install_pivariety_pkgs.sh https://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.shchmod +x install_pivariety_pkgs.sh./install_pivariety_pkgs.sh -p kernel_driverpress y to rebootNOTE: The kernel driver installation is only supported by the latest version 5.10. For other kernel versions, please go to our Doc page: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-to-install-kernel-driver-for-pivarietycamera/#2-how-to-build-raspberry-pi-kernel-driverfor-arducam-pivariety-cameraYou can also visit this doc page to refer to the hardware connection:https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/pivarietyog02b10-2mp-color-global-shutter-camera-module/
2. Test the Driver and CameraAfter you’ve finished the hardware assembly and driver installation, you can test whether the camera is detected and working.• View the Status of Driver and Cameradmesg | grep arducamIt will display arducam-variety if the driver installed success- fully and firmware version if the camera can be detected.The display should be probe failed if the camera can’t be detected, you might have to check the ribbon connection, then reboot the Raspberry Pi.• View the Video NodeThe Pivariety camera modules are emulated as the standard video device under /dev/video* node, so you can use the ls command for listing the contents in the /dev folder.ls /dev/video* -lSince the camera module is V4L2 compliant, you can use the V4l2 controls to list the supported color space, resolutions, and frame rates.v4l2-ctl –list-formats-extNOTE: Although the V4L2 interface is supported, only RAW format images can be obtained, without ISP support.
3. Official Libcamera App Installation./install_pivariety_pkgs.sh -p libcamera_dev./install_pivariety_pkgs.sh -p libcamera_apps
4. Capture Image and Record Video• Capture imageFor example, preview for 5s and save the image named test.jpglib camera-still -t 5000 -o test.jpg• Record videoFor example, record an H.264 10s video with the frame size1920W × 1080Hlib camera-vid -t 10000 –width 1920 –height 1080 -o test.h264NOTE: H.264 format only supports 1920×1080 and below resolution.• Plugin gstreamer installationInstall gstreamersudo apt updatesudo apt install -y gstreamer1.0-toolsPreviewgst-launch-1.0 libcamerasrc ! ‘video/xraw,width=1920,height=1080’ ! videoconvert ! autovideosink

3.  Failed to Install the DriverPlease check the kernel version, we only provide the driver for the latest official kernel version image when this Pivariety camera is released.Note: If you want to compile the kernel driver by yourself, please refer to Doc page: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-to-installkernel-driver-for-pivariety-camera/
4. Failed to import fd 18 terminate called after throwing an instance of ‘std:: runtime_error’ what( ): failed to import fd 18 Aborted If you find the same error, you may make the wrong selection about the graphics driver. Please follow the Arducam Doc page to select the correct graphics driver.If you find the same error, you may make the wrong selection about the graphics driver. Please follow the Arducam Doc page to select the correct graphics driver.
5. Switch to the native camera (raspistill etc.)Edit the file of /boot/config.txt, make dtoverlay=arducam change to # dtoverlay=arducam After the modification is completed, you need to reboot the Raspberry Pi.sudo reboot

NOTE: This camera module support trigger via an external signal, please refer to the Doc page to get the instruction https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-toaccess-pivariety-og02b10-2mp-color-globalshutter-camera-using-external-trigger-snapshotmode/If you need our help or want to customize other models of Pi cameras, feel free to contact us via[email protected]
