Recently, alwaysAI enhanced its CSI camera support with the Jetson line. Camera Serial Interface (CSI Cameras) defines an interface between a camera and a host processor, in this case the Jetson Nano. These cameras can be used in computer vision applications such as smart cars, drones, Internet of Things (IoT) appliances, wearables, and facial-recognition systems for security and surveillance technology.
In this week's Hacky Hour, Steve Griset, the CTO of alwaysAI identified how to change the drivers on an alwaysAI application to support these cameras. Steve covers how to deploy computer vision on two types of Jetson CSI Camera lenses (see below). Learn how to get your device ready for HD CSI cameras and how to use alwaysAI API’s with these devices.
To use the Jetson HD CSI cameras with alwaysAI, follow the following steps:
Change the driver IMX477 • Copy bl_update_payload_imx477 to /usr/sbin on the Nano • cd /usr/sbin • sudo dpkg-reconfigure nvidia-l4t-bootloader • sudo l4t_payload_updater_t210 bl_update_payload_imx477 • sudo cp libnvodm_imager.so /usr/lib/aarch64-linux-gnu/tegra/libnvodm_imager.so • Reboot the device
Change the driver back to IMX219 • Copy bl_update_payload_imx219 to /usr/sbin on the Nano • cd /usr/sbin • sudo dpkg-reconfigure nvidia-l4t-bootloader • sudo l4t_payload_updater_t210 bl_update_payload_imx219 • Reboot the device
