Road identifying by using electromagnetic sensor and camera in smart car field

Abstract

In the early centuries of 21st, self-driving becomes increasingly popular. Because of that, some technologies related to that are being studied and applied. Smart car control technology is one of these technologies including embedded technology, automatic control technology and so on. As for smart car field, there are two important methods to identify road, which are using electromagnetic sensors and using camera. In each method, there are different hardware structures to collect data and different code for microprocessor to process data. So in this essay, it will introduce the background technologies of smart car firstly. After that, basic principle of using electromagnetic sensors and camera will be given. Moreover, it will explain the code about using camera to achieve direction control and speed control. In this part, it will also give some applications of using camera to identify road elements. Finally, it will give a new method to control smart car by according to advantages and disadvantages of using camera and using electromagnetic sensors.
