| 1. e-CAM130A_CUXVR - FAQ |
| |
| 1.1 Why four cameras are used in NVIDIA® Jetson AGX Xavier development kit? |
| |
| With powerful processing capabilities and high number of camera support, the NVIDIA® Jetson AGX Xavier development kit is ideal for developing high-end multimedia devices in a small form factor. e-CAM130A_CUXVR camera uses four 4-lane MIPI cameras to stream 4K resolution at 30 fps in a synchronized manner. |
| |
| 1.2 What can I do to use the camera without synchronization? |
| |
|
You can easily disable the synchronization mode of the cameras using sample e-multicam.elf or ecam_tk1_guvcview application provided by e-con Systems and you can stream all the cameras individually without synchronization. Also, you can use v4l2-ctl application to disable frame sync control. |
| |
|
Run the following command to disable synchronization mode. |
| |
|
$ v4l2-ctl -c frame_sync=0 -d /dev/video<n> |
| |
|
Run the following command to enable synchronization mode with 30 fps. |
| |
|
$ v4l2-ctl -c frame_sync=1 -d /dev/video<n> |
| |
|
Run the following command to enable synchronization mode with 60 fps. |
| |
|
$ v4l2-ctl -c frame_sync=2 -d /dev/video<n> |
| |
|
Note: <n> depends on the camera for which frame sync control to be changed. |
| |
| 1.3 Do e-con Systems have any plan to support longer length cable? |
| |
| Currently, e-con Systems provide a very flexible and robust 30 cm micro-coaxial cable along with this kit. For customization, please write to camerasolutions@e-consystems.com with your requirement. |
 |
| 1.4 Can I boot the Jetson AGX Xavier development kit directly from the SD card shipped with the product? |
| |
| No, the SD card shipped with the product has the release package in .zip format. Since it is not a bootable SD card, it cannot be used to boot the Jetson AGX Xavier development kit. For customization, please write to camerasolutions@e-consystems.com with your requirement. |
| |
| 1.5 Is e-CAM130A_CUXVR camera support OpenCV? |
| |
e-CAM130A_CUXVR works using Video4Linux2 (V4L2) APIs and is V4L2 compliant. So, any V4L2 based application can be used to access this camera. OpenCV is also compatible since it uses V4L2 to access the camera.
Please refer to https://www.e-consystems.com/Articles/Camera/accessing_cameras_in_opencv_with_high_performance.asp for detailed information about OpenCV support in e-con Systems cameras.
|
| |
| 1.6 How can I get the updated package? |
| |
| Please login to the Developer Resources website and download the latest release package. |
| |
| 1.7 Is this product support six cameras? |
| |
| No, this product support upto four cameras. For customization, please write to techsupport@e-consystems.com. |
| |
| 1.8 Can I connect cameras in any of available six connectors? |
| |
| No, please refer to Figure 1 to connect the cameras. If there is an improper connection, the camera driver will not be loaded properly. The cameras must be connected in CAM_A, CAM_C, CAM_E and CAM_F port. |
