The requirements for the cameras that will work with the Train detection module are listed in the following table.
Camera | - Resolution should be at least 640x480 pixels.
- Fps: not less than 6
- Color: analytics works with grey and color images.
- Camera shaking should not result in image offsets greater than 1% of the frame size.
|
Lighting | - Medium lighting. In conditions of insufficient (night) or excessive (exposure) lighting, the quality of analytics can be reduced.
- No sharp changes of lighting.
|
Scene and camera angle | - Camera is to be directed in the line of the railway or as close to it as possible.

Objects image | - At the time the detector was started, there was no train in FoV.
- Minimum overlapping of moving objects with the static objects in the scene (columns, trees, etc.).
- Analytics may not work correctly on reflective surfaces and if there are sharp shadows from moving objects.
- The width and height of objects in the image should not exceed 75% of the frame size.
- The speed of objects in the image should not be less than 1 pixel per second.
