Video stream and scene requirements for Equipment detection tool (PPE) operation

The Equipment detection tool (PPE) operation imposes the following requirements:

To the video stream from the camera:
1. 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.
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.
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.
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.

Attention!

Correct operation of the detection tool is not guaranteed when using a fish-eye lens.
