For PPE detection under a neural tracker, The Equipment detection tool (PPE) operation imposes the following requirements should be matched: Camera requirements for neural tracker operation

For PPE detection under a video camera, the following requirements should be matched:

  1. To the video stream from the camera:
    1. The
    Minimum
    1. resolution is at least
    640х480 pixels.
  2. Frame rate is no less than 3 FPS.
    1. 640x360 pixels. It is also not recommended to use a resolution higher than 1920×1080, since higher resolution does not increase the detection quality, but significantly increases the consumption of resources. The optimal resolution for solving typical tasks is 1280x720.
    2. The frame rate per second in the video stream from the camera is at least 3 for solving typical tasks.
    3. Color image only.
  3. To lighting:
    1. Lighting in the scene is at least 200 lux per square meter. In conditions of insufficient or excessive lighting (night or light-striking), stable operation of the video analytics is not guaranteed.
    2. There are no abrupt changes in lighting.
  4. To the scene and camera angle:
    1. Moving objects are visually separable from each other.
    2. The background is mostly static and does not change abruptly.
    3. There are no products made of rods in the detection area.
    4. Moving objects are minimally obscured by static objects in the scene (columns, trees, etc.).
    5. The analyzed scene does not have reflective surfaces and sharp shadows from moving objects. If present, they should be masked.
    6. Camera shake does not result in image offsets greater than 1% of the frame size.
    An object (its bounding rectangle) must occupy no less than 18% of the FOV. 
Note
titleAttention!

We cannot guarantee normal Correct operation of PPE detection with a fisheye camerathe detection tool is not guaranteed when using a fish-eye lens.
