Embedded Files
Dragon-eye is an electronic real-time F3F judging system using the Jetson
Nano. It is based on the technology of computer vision, capturing a video stream
from the camera, then detecting moving objects and tracking them. Once one of the
tracked targets crosses the central vertical line a signal is triggered.
Feature
- Multi moving targets tracking base on technology of background subtraction (MOG2)
- Camera resolution is 720p and frame rate is limited to 30 fps
- Supports selection 1 of 2 cameras with different angle of view
- Trigger out GPIO / UART / UDP when target across central line
- Record video files to SD card with or without tracking result
- Built-in wifi AP for connectivity
- Built-in RTSP video server (H.265 codec)
- Video output can be one of the following option HDMI / RTP / HLS / RTSP (Prefer RTSP)
- Android APP to start / stop / config / play RTSP video stream
- Written in c/c++ for running performance
- Background subtraction runnung by GPU to improve real-time performance
- Camera settings for different scenes such as dim light or over exposure
- Adjustable MOG2 threshold to reduce nosie or improve object detection
Android APP
- Remote control dragon-eye from Android phone
- Connect dragon-eye through wifi
- Start / Stop dragon-eye
- System config / Camera config
- Play video from RTSP server of dragon-eye
- Play sound with trigger
