Vehicle Speed Measurement Using Stereo Camera Pair
This thesis aims to answer the question whether it is currently possible to autonomously measure the speed of vehicles using a stereoscopic method with the average error within 1 km/h, the maximum error within 3 km/h, and the standard deviation within 1 km/h. The error ranges are based on the requirements of the OIML whose Recommendations serve as templates for metrological legislations of many countries. To answer this question, a~hypothesis is formulated and tested. A method that utilizes a stereo camera pair for vehicle speed measurement is proposed and experimentally evaluated. The experiments show that the technique overcomes state-of-the-art results with the mean error of approximately 0.05 km/h, the standard deviation of less than 0.20 km/h, and the maximum absolute error of less than 0.75 km/h. The results are within the required ranges, and therefore the formulated hypothesis holds.
