Technical field
The present invention relates to safety door control field, more particularly to a kind of station platform safety door anti-pinch platform.
Background technology
On April 5 nineteen fifty-nine, first high-speed railway Tokaido the Shinkansen truly is in Japanese break ground and start building in the world
Work, built by 5 years, completely completed to lay a railway track in March, 1964, July in the same year is completed, and is formally open to traffic on October 1st, 1964.The East Sea
Road the Shinkansen is originated from Tokyo, and by way of Nagoya, capital of a country and other places eventually to (new) Osaka, 515.4 kilometers of total length, overall trip speed is up to
210 kilometers/hour, being open to the traffic for it indicates the epochal arrival of world's high-speed railway.Then France, Italy, Germany
Build high-speed railway one after another.Japan has built adret, northeast and upper more the Shinkansen again after Tokaido the Shinkansen within 1972；
France has built southeast TGV lines, Atlantic Ocean TGV lines；Italy has built Rome to Florence.The first generation headed by Japan
High-speed railway is built up, and has been promoted the balanced development of regional economy along the line energetically, has been promoted real estate, industrial machinery, steel etc.

Size and specific geometry and topological features.
One kind in common image filtering pattern is nonlinear filter, it is, in general, that when signal spectrum and noise frequency
Such as the noise as caused by mission nonlinear or there are non-gaussian to make an uproar when composing aliasing or when containing nonadditivity noise in signal
Sound etc.), traditional linear filter technology, such as Fourier conversion, while noise is filtered out, always blurred picture is thin in some way
Section (such as edge) and then the extraction property reduction for causing the positioning accuracy and feature as linear character.And nonlinear filter is
Based on a kind of Nonlinear Mapping relation to input signal, often a certain specific noise approx can be mapped as zero and retained
Signal wants feature, thus it can overcome the shortcoming of linear filter to a certain extent.
