In this paper, a vision-aided navigation method for aircraft is proposed. The road network is detected from ground scenes provided by down-looking camera. The road junctions are extracted and referenced. Based on the principle of camera calibration, the position of the aircraft can be estimated by the road junction matching pairs in image and digital map. It is then employed to fix the accumulative...
When the circuit board schematic of spare parts are hardly obtained, it is of importance and significance that circuit board schematic validating system is designed, by which the circuit board schematic is calibrated and the spare parts can be designed and produced. On the basis of the combination of virtual instrument and developed in this paper, a circuit board schematic validating system is designed...
Aiming at the problem of a great deal of blindly searching the proportional, differential, integral parameters in the process of designing PID controller, the new algorithm combining genetic algorithm with iterative learning algorithm is named as an iterative learning genetic algorithm (ILGA), which can be used to optimize three controller parameters, thus the optimal parameters can be achieved swiftly...
