Hello NVIDIA Community,
I’m currently working on a project using my NVIDIA Jetson Nano 2GB board and a Raspberry Pi Camera Module V2 to perform real-time object detection using YOLO. I’ve been able to successfully use YOLOv8 for object detection on a static image, but I’ve encountered an issue when trying to use it with a live camera feed.
System Details:
- Jetson Nano 2GB (Running JetPack 4.6.2)
- Raspberry Pi Camera Module V2
- Python Version: 3.11.2 (installed within a virtual environment)
- Ultralytics YOLO Version: 8.3.111
- Torch Version: 2.5.1
- OpenCV Version: 4.7.0
- GStreamer Version: Installed from system packages (via
apt-get
)
The Problem:
I am trying to capture video from the camera in real-time and run object detection on the video feed using the YOLOv8 model. For camera capture, I am using GStreamer pipelines, but I am facing issues with GStreamer not being able to open the camera stream through OpenCV’s cv2.VideoCapture()
.
The Code:
The Issue:
When running the code, I encounter the following error:
Error: Unable to open camera
### Troubleshooting Steps Taken:
1. **Camera Test**: I confirmed that the camera is working perfectly by testing it using commands such as:
* `nvgstcapture-1.0`
* `gst-launch-1.0 nvarguscamerasrc ! nvoverlaysink`
* `gst-launch-1.0 nvarguscamerasrc ! videoconvert ! autovideosink`
These commands work fine, and the camera produces a video feed.
2. **GStreamer Version**: I’ve verified the installed GStreamer version using:
gst-launch-1.0 --version
The version is 1.14.5
4. **OpenCV with GStreamer**: I've tested using OpenCV with the GStreamer pipeline, but I still get the error `Unable to open camera`.
### My Setup:
* **Jetson Nano 2GB** with JetPack 4.6
* **Raspberry Pi Camera Module V2** connected via the CSI interface.
* **GStreamer** installed
* **OpenCV** version: 4.11
* **YOLOv8** model for object detection.
### Questions:
1. Has anyone encountered a similar issue with using GStreamer for camera capture on the Jetson Nano? What could be causing the `Unable to open camera` error?
2. Are there any other approaches or libraries I can use for capturing video from the camera on Jetson Nano (besides GStreamer)?
3. Is there any configuration or setup step I may have missed regarding GStreamer or OpenCV for real-time video capture on Jetson Nano?
I would appreciate any help or suggestions to resolve this issue. Thank you in advance!
Best regards,
Anis
