The requirements for the cameras that will work with the Person location tracker module are listed in the following table.

...

Camera

...

  • Resolution: 640х360 pixels.
  • Correct operation is not guaranteed with fish-eye lenses
  • Fps: not less than 1. For dynamic objects, at least 2 frames per second is recommended. The higher the frame rate, the more accurate the posture detection is. At 1 fps, the accuracy will be not less than 70%

...

Lighting

...

  • The objects must be visually separated from the background and from each other

...

Scene and camera angle

...

  • The camera shall be installed at an angle at a height of at least 3 meters

Video stream from camera

  • 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.
  • The frame rate per second in the video stream from the camera is at least 8.
  • Color image only

Lighting

  • Lighting in the scene is at least 50 lux per square meter. In conditions of insufficient or excessive lighting (night or light-striking), stable operation of the video analytics is not guaranteed.
  • There are no abrupt changes in lighting

Scene and camera angle

  • Moving objects are visually separable from each other.
  • The background is mostly static and does not change abruptly.
  • Moving objects are minimally obscured by static objects in the scene (columns, trees, etc.).
  • The analyzed scene does not have reflective surfaces and sharp shadows from moving objects. If present, they should be masked.
  • Camera shake does not result in image offsets greater than 1% of the frame size

Note
titleAttention!

Correct operation of the Pose detection tools is not guaranteed when using fisheye cameras and other cameras with strong image distortion.
