2004《Road vehicle contour dimension, axle load and quality limit value》、GB7258-2014《Motor vehicle safe and technical specification》、
GB21861-2014《Motor vehicle detecting project and method》Deng judging whether vehicle transfinites.What existing measuring technique obtained
Vehicle overall dimension is often inaccurate and wasting manpower and material resources so that numerous manufacturers one after another survey sight car of turning direction contour dimension
Direction is measured, however the product quality produced is very different, in practical applications, since the factor that design scheme considers is not complete enough
Face causes measurement result inaccurate, cannot be up to state standards, and easily causes the dispute between driver and law enfrocement official, therefore accurate
Really, reliable intelligent, non-contact vehicle contour dimension measurement method is urgently studied.
Utility model content
