The average sizes of faces and license plates may vary across countries. The calculation reflects the ideal situation based on perfect lighting conditions and target’s orientation towards camera. Fog, rain, snow, night time, headlights of the car, fast moving objects, objects not facing the camera directly – these factors may all reduce the distance for object recognition. For critical projects, please do the validation by using the actual camera model.
