The requirements for the video stream and the scene when working with the Neurotracker module are given in the table:

Video stream from camera

  • The resolution is at least 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 (see Examples of configuring neural tracker for solving typical tasks).
  • The frame rate per second in the video stream from the camera is at least 8 for solving typical tasks.
  • Both colorless (gray) and color images

Lighting

  • Lighting in the scene is at least 50 lux per square meter. In conditions of insufficient or excessive lighting (night or light-striking), stable operation of the video analytics is not guaranteed.
  • There are no abrupt changes in lighting

Scene and camera angle

  • Moving objects are visually separable from each other.
  • The background is mostly static and does not change abruptly.
  • Moving objects are minimally obscured by static objects in the scene (columns, trees, and so on).
  • The analyzed scene does not have reflective surfaces and sharp shadows from moving objects. If present, they must be masked.
  • Camera shake does not result in image offsets greater than 1% of the frame size

Objects image requirements for neural tracker


Correct operation of the neurotracker isn't guaranteed if you use a fisheye lens.

Correct operation of the neurotracker isn't guaranteed if you use a video stream or frames that were masked before they got into Axxon PSIM by an IP camera or similar means and methods.
