MEASURING METRO TRAIN'S SPEED BY ON-BOARD OPTICAL SENSORS
Abstract
The optical methods of measuring the speed of trains in metro by onboard sensors are studied, including situations of train's approach to another object. In solving these tasks the experience of the development of opto-electronic devices for probable future spacecrafts is used. It is shown that the smallest measurement uncertainty is provided by considering the effect of geometric distortion of the image formed by CMOS photodetector. The sensors are able to fulfill the role of reserves in the system of automatic train control, thereby enhancing reliability and safety of passenger traffic.
