The requirements for the cameras that will work with the Stopped vehicle detection module are listed in the following table:
Camera | - Resolution should be at least 720x480 pixels
- Fps: not less than 15, recommended fps is 25
- Camera should be rigidly fixed to avoid shaking
|
Scene and camera angle | - Recommended height of camera mounting: 6-7 m
- Recommended angle of camera mounting: no more than 30 degrees relative to the horizontal line
- It is recommended to mount camera above the middle of analyzed traffic area
- If the camera is installed on the side of the traffic area, the efficiency of the detection algorithm decreases
|
| Object images | - The vehicles and their elements, for example, a radiator grill, should be visually distinguishable on the video image
- It is recommended to use the Zoom-In/Zoom-Out camera functions to improve the response reflection from vehicles on the scene, i.e. settings in which the vehicle elements are clearly distinguishable
|
| Lighting requirements | - Objects should be visually separated from the background and from each other.
