Image 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:

Camera
  • Resolution must be at least 640x360. We also don't recommend using a resolution higher than 1920×1080, since higher resolution doesn't increase the detection quality, but significantly increases the consumption of resources. The optimal resolution for solving typical tasks is 1280x720
  • The frame rate per second in the video stream from the camera is at least 3 for solving typical tasks
  • Detection-based analytics works with color images only

Attention!

  • Correct operation of the detector isn't guaranteed if you use frames that were masked before they got into Axxon One by an IP camera or similar methods.
  • Correct operation of the detector isn't guaranteed if you use a fisheye lens.
  • The camera tilt angle from top to bottom on a person wearing equipment must not exceed 30°. Otherwise, the detector won't operate correctly.
    The following diagrams show the examples of:
    • The acceptable tilt angle:
    • The unacceptable tilt angle:
Lighting
  • Lighting in the scene is at least 200 lux. The detector is applicable in conditions of artificial light. In conditions of insufficient or excessive lighting (night or light-striking), stable operation of the analytics isn't guaranteed
  • No abrupt changes in lighting
Scene and camera angle
  • Moving objects are visually separable from each other
  • The background is mostly static and doesn't change abruptly
  • There are no products made of rods in the detection area
  • Moving objects are minimally obscured by static objects in the scene (columns, industrial products, and so on)
  • The analyzed scene doesn't have reflective surfaces. If present, they must be masked
  • Camera shake doesn't result in image offsets greater than 1% of the frame size



  • No labels
