Description
Technical field
The present invention relates to the continuous fracture width scanner of a kind of high precision, belong to the engineering Inspection Technique field.
Background technology
At present, in concrete structure engineering, the width of concrete surface crack and development form are important indicators of grade estimation; Concrete surface crack width observation at present generally has three kinds of traditional methods: first method is to adopt optics gap observation appearance; Principle of work is decided the multiple optical loupes for adopting, and has rule in the visual field, can tested fracture width be measured; It has led light source, can throw light on and not limited by ambient light tested crack; During use with optics gap observation appearance be placed on the crack directly over; Be adjacent to measured surface, eyes are adjacent to the eyepiece end and fracture width is surveyed are read, and the characteristics of this method are that equipment is simple, cheap; But shortcoming is to need artificial the survey to read; Once can only measure a fracture width value, work efficiency is lower, is not suitable for the workplace of large tracts of land crack scanning.Second method is to adopt closely fracture width visualizer; Principle of work is for adopting camera as graph capture device, camera directly be placed on tested crack directly over, through the tested crack of main frame screen viewing, through scale on the screen or the tested fracture width value of automatic interpretation functional measurement.The characteristics of this method are that the crack is surveyed and to be read conveniently, can graphics, but shortcoming also is once to measure a fracture width value, work efficiency is lower, is not suitable for the workplace of large tracts of land crack scanning equally.The 3rd method is to adopt remote fracture width visualizer; The method is that its principle of work is carried out IMAQ for adopting telephoto lens with remote object image-forming on camera for the concrete surface crack of observing high-altitudes such as bridge build designs; While calibration measurements distance, detection inclination angle; Proofread and correct through multistep, can the telemeasurement fracture width, length, the characteristics of this method are can the remote observation crack; But shortcoming is that measuring speed is slow, inefficiency, is not suitable for the workplace of large tracts of land crack scanning.
Summary of the invention
The object of the present invention is to provide a kind of continuous fracture width scanner of high precision that can overcome above-mentioned technical matters.
The present invention includes: the host computer system, path cable, camera cable, the array image scanister that are used for image mosaic and crack interpretation; Said array image scanister adopts two-way double wheel construction; Double four wheels that camera array one side is set on said array image scanister can be fitted with tested fracture faces fully; Guarantee that camera array keeps constant to the vertical range of tested fracture faces, to reach the stable purpose of scanning fast; Two wheels of a row of the bottom surface of said array image scanister can be fitted with the normal surface of tested fracture faces, move along straight line to guarantee the array image scanister; Be arranged on the motion conditions that rotary encoder on the array image scanister is used for real-time measuring wheel; Promptly measure the straight-line displacement information of array image scanister, and displacement information is controlled to carry out automatic shooting to tested crack surface image to host computer system through the path cable transmission.
The said camera array that is arranged on the array image scanister is connected through the camera cable with said host computer system; The said rotary encoder that is arranged on the array image scanister is connected through the path cable with said host computer system.
Said rotary encoder includes but not limited to following type: optical rotary encoder, electromagnetism rotary encoder, galvanically rotary encoder, capacitance-grid type rotary encoder etc.
Principle of work of the present invention is: on said array image scanister, camera array is set; The coordinate of camera array is carried out displacement measurement and carry out automatically a series of matrix images are obtained in the shooting control of tested crack surface image through being arranged on rotary encoder on the array image scanister; Image mosaic software by in the host computer system splices processing to matrix image, generates the crack high-definition image that covers sweep limit; By the crack interpretation software in the host computer system crack high-definition image is carried out Treatment Analysis again, interpretation analyzes information such as the position, trend, width in crack.
Advantage of the present invention is to have solved effectively the technical barrier that continuous sweep detects is carried out in the crack on large area concrete surface; Have that test speed is fast, high efficiency, measuring accuracy are high, the characteristics of good stability; Human cost and time cost have greatly been saved; And simple to operation, have stronger practical value and realistic meaning.
