The UFO Detector is a software that allows the autonomous video recording of unidentifiable flying objects. This includes unknown aircrafts, meteors or other aerial anomalies. It is designed to detect and record objects that cannot be identified as something known during the day or night. See it in action
Features:
- Autonomous video recording of possible UFO’s
- Interface to manage all the recorded videos
- Sharing of captured video with UFOID.net
- Selection of specific detection area
- Currently support in Windows and Linux. Raspberry Pi has been planned (https://github.com/UFOID/UFO-Detecor-Pi).
Requirements:
- USB Webcam
- OpenCV 3.0 (2.4.8 will work in Ubuntu 14, but 3.1.0 is required in Ubuntu >=15)
- Qt 5
- FFmpeg / avconv
ToDo:
- Interface to support more video devices
- Improve detection algorithm
- Many bug fixes
Building and Running
First, get the source code for UFO Detector by either cloning this repository or downloading the source as a ZIP package. See the 'Clone or download' button above.
Windows
- Install the prerequisites, see the list above.
- Open the project file ...UFO-Detectorui-qtDetector.pro in Qt Creator. Edit OpenCV paths in opencv.pri so they point to correct locations.
- Build the project. You can run the application from Qt Creator or from command line in the build directory.
Generic Notes for Building in Linux
If your distribution has OpenCV version other than 2.4.9 through 3.0.0, you should be able to build UFO Detector with the development packages from the normal repositories. In that case, read the instructions for Ubuntu Linux 14 and apply them to your distribution. If UFO Detector has problem writing videos correctly you know you have the buggy version of OpenCV, in which case read the next paragraph.
OpenCV versions between 2.4.9 through 3.0.0 have a bug, at least in Ubuntu Linux, causing video writing to fail. This means OpenCV >=3.1.0 need to be installed by hand. For that, read the instructions for Ubuntu Linux >=15 and apply them to your distribution.
Ubuntu Linux 14
First, install Qt5, avconv/ffmpeg, and OpenCV development packages:
sudo apt-get install qtbase5-dev libav-tools libopencv-dev qt5-default
If this is not enough, check if you need to install other development packages as well.
Open the project file .../UFO-Detector/ui-qt/Detector.pro in Qt Creator and build it. You can run the application from Qt Creator or from command line in the build directory.
Ubuntu Linux >=15
In Ubuntu Linux >=15, first install Qt5 and avconv/ffmpeg, plus the necessary packages for compiling OpenCV. Installing libopencv-dev package is optional because it will not be used.
sudo apt-get install qtbase5-dev libav-tools build-essential cmake libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev qt5-default
Next, download OpenCV 3.1.0 source package for Linux and unzip it. It's assumed here the target folder is opencv-3.1.0. Then run the following commands in the same folder in which you unzipped the source package:
If you use IPP ICV, turn it ON and figure how to make it work (didn't work out of the box).
For more info about OpenCV, please refer to OpenCV building instructions.
Open the project file .../UFO-Detector/ui-qt/Detector.pro in Qt Creator and build it. You can run the application from Qt Creator or from command line in the build directory.
Detection Algorithm:
Uforio 1.0 Pro
Since the objects that the software looks for are not well defined (i.e. being “unknown”) false positive detections are expected. We use a combination of following algorithms in order to narrow down the results:
- Motion Detection: The program looks for moving objects within the selected area of detection. The user can specify the size of noise which will be ignored. Each moving object is tracked.
- Light detection: We assume any UFO is light emitting (i.e. object being brighter than the background) in order to decrease the amount of false-positives.
- Object recognition: Each detected bright object is analyzed using cascade classifier which was trained using images of flying birds. This is only used if the detection process is run during the day. Currently only birds are filtered out in this way.
- Aircraft filter: Using data from the internet to check whether there are aircrafts within the camera view.
