The requirements for 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. We also don't recommend using 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 1280x720 (see Examples of configuring neural tracker for solving typical tasks).
- The frame rate per second in the video stream from a camera is at least eight for solving typical tasks.
- Detector-based analytics works with colorless (gray) and color images
|
Lighting | - Lighting in the scene is at least 50 lux. In conditions of insufficient or excessive lighting (night or light-striking), stable 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 doesn't change abruptly.
- Moving objects are minimally obscured by static objects in the scene (columns, manufactured goods, and so on).
- The analyzed scene must not have reflective surfaces and sharp shadows from moving objects. If present, they must be masked.
- Camera shake must not result in image offsets greater than 1% of the frame size
