ERRORS OF THE VIDEO CAMERA, SPEEDOMETER AND NAVIGATOR

Abstract

Types of errors, types of the used devices for measurement of cars’ speed installed in the car motor, and devices of video and photo speed fixing devices during the cars movement are considered in this paper. Construction features of the above-stated devices are given. It is shown that the most precision instrument is the navigator which works with use of system of global positioning of GPS in the presence of the Internet. Values of measurement of speed by means of speedometers are overestimated by producers of cars for the purpose of driving safety. Comparison of mechanical and electronic speedometers is carried out. Factors on which the accuracy of measurement of speed speedometers and video photo clampers depends are given. The error values of the video and camera coincide with the limit of the allowed speeding of the car, which allows you to challenge the penalty for speeding the car. It is shown that the navigator has the smallest error.
