Simulation Study for One Kind of Stereo Computer Vision Scheme

A computer vision solution scheme for the automatic landing of an unmanned helicopter on ship was examined from the view of engineering application.A series of computer vision algorithms such as Sobel filter and Fast Hough Transform were adapted and integrated to get the relative positions between the helicopter and ship,from which their relative movement parameters could be obtained.A new kind of Fast Hough Transform was developed to detect the linear parameters,and the speed of which is 10 times faster than the standard Hough Transform.The new Hough Transform makes the stereo vision scheme very robust to noise.Computer simulation results indicate that the presented algorithms are robust and reliable.
