| Research Abstract |
This work is concerned with the vehicle navigation.
We proposed the new navigation method which uses the ceiling fluorescent lamp as a lighthouse. The fluorescent lamp has two merits on this navigation as follows : it is easy to be detected and exists in most factories. Especially, it is the remarkable merit that the fluorescent lamp is easy to be extracted from the general scene on the camera image when the camera iris is narrow because of its high contrast to background. This navigation system is composed of the camera, the personal computer, the moving mechanism and their interfaces. All units are not special ones.
This work is divided into next two parts.
1 Guided navigation
Fluorescent lamp are used as a guide on vehicle navigation. This system is simple, cheap and, can realize the stable moving. It is easy to be replaced on the system which works in practical factories. After this quick lamps detection method was discussed, we realized the straight and turning motion in the practical speed. The simulation of the overall motions in the factory was offered. We received the 1996 paper award of the society of System Control and Information.
2 Measurement of position and orientation of vehicle and control method
We studied the method of measuring the position and orientation of the vehicle and the control method to realize the more flexible and precision moving. Our vehicle has no serve control system. So, the Kalman filter was used to estimate the steering angle. This filter system can offer the smooth moving. Furthermore, in order to adopt on the various circumstances, the flexible position measurement and control system were studied. It was confirmed that this system had the high adaptability in the unknown field. This study is useful on the general position measurement researches.
