Requirements for the operation of the Equipment detector VL and its sub-detectors are given in the table:
| Camera | - Resolution must be at least 640x360. We also don't recommend using
|
The PPE detection tool (VL) operation imposes the following requirements:
...
- 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
|
...
- 1920x1080
- The frame rate per second in the video stream from the camera is at least 13 for solving typical tasks
|
...
- Detection-based analytics works with color images only
| Note |

| Correct operation of the detector isn't guaranteed when you use a fisheye lens. |
|
| 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

- No abrupt changes in lighting

...
...
| - Moving objects are visually separable from each other
|
...
- The background is mostly static and
|
...
...
- 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)
- Avoid large obstructions in the camera FOV (columns, tower cranes, stacked materials,
|
...
- and so on). They will obscure the detected objects and cause track breaks. If obstructions cannot be avoided,

- we recommend not placing them in the center of the frame

- doesn't have reflective surfaces
|
...
...
...
...
- doesn't have strong light flashes (spotlights, active welding zones)
|
...
...
- doesn't result in image offsets greater than 1% of the frame size
|
...
- Shooting angle without a strong camera tilt
|
...
- To improve the quality of the video stream, the camera lens

- must be cleaned of heavy dirt.
|
...
- We don't recommend locating cameras above the material unloading area or near ventilation shafts
