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

Hardware requirements for neural analytics operation

Requirements for the operation of the Equipment detector are given in the table:

Object images
  • The detected object (equipment or PPE) must be clearly distinguishable by the human eye
  • The image isn't noisy and not distorted by the artifacts of compression algorithm
  • The width or height of the equipment doesn't exceed 75% of the frame size
  • The duration of the object's visibility is at least 3–8 frames. The minimum number of frames depends on the task
  • There are no visible physical barriers between the camera lens and the analyzed object

  • The minimum sizes of equipment on body parts in pixels are observed. Example of equipment dimensions for a resolution of 1920x1080:

    • Upper body (torso) 75*100

    • Legs 75*105

    • Head 60*65

    • Hands 65*60

    • Feet 45*40

    • Set of equipment 165*295

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