Description

A kind of airfield pavement carefully sees shape measurement system and control evaluation method
Technical field
The invention belongs to airport engineering technical fields, and shape measurement system and control are carefully seen more particularly to a kind of airfield pavement Evaluation method processed.
Background technology
With the increase of airfield runway service life, road face will appear different degrees of breakage, and airport needs to carry out thus The real-time oversight of road face damaged condition, to ensure the operational safety of runway.For this problem, domestic and foreign scholars propose a variety of Solution.For example the drafting etc. of a cloud is carried out using the method shooting road face image of image recognition, using laser total station.This The it is proposed of a little methods, for analyzing that surface damage type and extent have prodigious contribution.But such equipment is only capable of completion one Class works, i.e. the recovery of road face image, and the reconstruct of construction can not be carefully seen into trade face.
Construction is carefully seen as subtle variation occurs for the service life increase of runway in road face, and this variation shows thin bone The exposing of material to fall off with coarse aggregate changes runway friction coefficient, therefore there are serious peaces so as to cause aircraft to prick tire Full hidden danger.With conventional method it can be found that the damage of road face but being limited by Airport Operation management requirement, can not apply and Runway operation Management is practical.Therefore it needs to find new technical method and solves the problems, such as this.
If this can be solved the problems, such as, realizes that runway carefully sees the reduction of construction, the guarantor of Runway operation safety will be effectively improved Barrier ability, has important practical significance.
Invention content
To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of airfield pavements carefully to see shape measurement system and control Evaluation method processed.
