| Abstract: | The design of the autonomous tracing intelligent vehicle was introduced and the software and hardware design method which realized autonomous tracing using charge coupled device(CCD)as the path recognition module was discussed.The black-and-white CCD output real-time video signals were gathered and processed by the key controller of Texas Instrument corporation's TMS320LF2407A.Path information was got by an edge detection algorithm.The P algorithm was utilized on the servomotor and the drive motor.It can make the intelligent vehicle travel fast and fluently.It is shown that the design program has a good autonomous tracing effect on the black and white(or large color-difference)track. |
