Camera positioning is very important, and where-ever possible the camera should be positioned in front of a vehicle so that the vehicle ‘approaches’ the camera, it can be slightly above or to one side.
It is important to achieve an angle of view whereby the target vehicle stays in the Area of Interest for as long as possible such that a number of consecutive, identical results can be obtained, this is not likely to happen with a high angle of incidence to the vehicle whereby the vehicle ‘passes by’.
The following image shows a high angle of incidence from camera to the white van, the RoboPlate camera cannot recognise it’s plate, it can however recognise the three cars.
The diagram below shows typical positioning of the camera at which good results can be expected, as the angle of incidence increases, results will become less accurate.
