For Requirements for the correct operation of video analytics to work correctly, the following requirements must be metare given in the table:
...
...
...
...
...
...
...
...
- Video analytics works with both black-and-white and color images
|
...
- Camera shaking must not cause image shifting of more than 1% of the frame size
|
...
...
...
- Insufficient or excessive lighting (night
|
...
...
- bright sunlight) may impact the quality of video analytics
|
...
...
- abrupt changes in lighting
|
...
...
...
- are visually separable from each other
|
...
...
- is mostly static and doesn't change abruptly.
- Moving objects are minimally obscured by static objects in the scene (columns, industrial products, and so on)
|
...
- Reflective surfaces and harsh shadows from moving objects can affect the quality of analytics
|
...
...
- Long single-color objects may not be tracked properly
|
...
...
...
| - An object must be visible on the image
|
...
- There is no noise on the video image and there are no artifacts caused by the compression algorithm
|
...
- The width and height of objects in the video should not be less than 1% of the frame size (at resolutions not less than 1920x1080 pixels) or 15 pixels (at lower resolutions)
|
...
- The width and height of objects in the video should not be more than 75% of the frame size
|
...
- It is recommended that the linear measurements of objects in the frame do not exceed 75% of the frame size
|
...
- The speed of objects in the frame must be at least 1 pixel per second
|
...
...
...
- Quantity of simultaneously tracked objects on a
|
