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
- The analyzed scene
|
...
- doesn't have reflective surfaces
|
...
...
...
- The analyzed scene doesn't have strong light flashes (spotlights, active welding zones)
- Camera shake
|
...
- 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.

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

- We don't recommend locating cameras above the material unloading area or near ventilation shafts
