According to requirement of the auto rack girder detection
the real time visual detecting system is designed. Sequence images having features need to be real-time stitched and an improved Fourier field stitching algorithm which is applied to stitch sequence images of the Auto Rack Girder is put forward in the paper. It is selected within overlapped areas of image at first large region and two-dimension pulsing signal is gotten after cross-power spectrum is counted. Registration parameters are gained through maximum of pulsing signal. To bundle images
a new weighting image smoothing algorithm based on Canny is put forward. To some extent
the algorithm has general adaptability to some factors such as lamination variation
noise and so on. With the fast stitching speed
the algorithm is adopted to fast stitch a lot of sequence images.
