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.

  • 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.
  • No labels
