This master’s thesis deals with vehicles speed measurement. The first part is a theoreticalanalysis with an overview of the measurement devices, which are being used nowadays.The second part of the thesis focuses on creating a method for vehicles speed measure-ment in a common traffic situaction. Measurement is based on digital image processingfrom a camera and determining the movement in the image.For movement determination is used license plate detection and other possible methodsare explained in the thesis for future improvement.Created measurement method is using vehicle with known proportions for visual scenecalibration. The MATLAB programming environment is used to detect license plate andfor calibration.Test measurement is conducted ...
