Video stream and scene requirements for the Equipment detector VL and its sub-detectors

Hardware requirements for neural analytics operation

Requirements for the operation of the Equipment detector VL and its sub-detectors are given in the table:

Correct operation of the detector isn't guaranteed when you use a fisheye lens.

Object images
  • The detected object (equipment or PPE) must be clearly distinguishable by the human eye
  • Color image, isn't noisy and isn't distorted by the artifacts of compression algorithm
  • Linear dimensions of equipment or PPE must not exceed 65% of the corresponding frame size
  • The duration of the object's visibility is at least 10–13 frames. The minimum number of frames depends on the task
  • There are no visible physical barriers between the camera lens and the analyzed object
  • Obscuring of a person and/or PPE by an obstruction and/or by another person, and/or cropping by frame boundaries must not exceed 25%

  • The minimum sizes of equipment on body parts in pixels are observed:

    • Vest—at least 50 pixels

    • Helmet/Hood—at least 20 pixels

  • PPE must have a standard look and shape, and have the following colors:

    • Vest: green, yellow, orange

    • Helmet/Hood: white, yellow, orange, red, blue, green

  • The minimum value of pixel density per meter is observed:
