The requirements for the video stream and the scene when working with cameras when you work with the Neurotracker module are given in the following table:.
Video stream from camera | - The resolution is at least 640x360 pixels. It is also not recommended to use We also don't recommend using a resolution higher than 1920×1080, since higher resolution does not doesn't increase the detection quality , but significantly increases the consumption of resources. The optimal resolution for solving typical tasks is 1280x720 (see see Examples of configuring neural tracker for solving typical tasks).
- The frame rate per second in the video stream from the a camera is at least 8 eight for solving typical tasks.
- Both Detector-based analytics works with 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 analytics operation isn't guaranteed.
- There are no abrupt changes in lighting
|
Scene and camera angle | - Moving objects are visually separable from each other on an image.
- The background is mostly static and does not doesn't change abruptly.
- Moving objects are minimally obscured by static objects in the scene (columns, treesmanufactured goods, and so on).
- The analyzed scene does must not have reflective surfaces and sharp shadows from moving objects. If present, they must be masked.
- Camera shake does must not result in image offsets greater than 1% of the frame size

Correct operation of the neurotracker isn't guaranteed We don't guarantee the correct neurotracker operation if you use a the fisheye lens. Correct The correct operation of the neurotracker isnthe neurotracker isn't guaranteed if you use a the video stream or frames that were masked before they got into into Axxon PSIM by an the IP camera or similar means and methods. |
