Description
Technical field
The present invention relates to a kind of scanner and scan method, a kind of scanner for solid content upper surface and scan method, such as scanning the scanning of concrete carbonization depth.
Background technology
The carbonization of concrete mainly due to the carbon dioxide in air by the Micro-v oid of concrete, microfissure enter in concrete with concrete hole solution calcium hydroxide reaction generate calcium carbonate process, in this process, owing to generating calcium carbonate (insoluble salt), inside concrete can be made to produce expand, the calcium hydroxide of alkalescence is reacted simultaneously, and concrete will present neutrality.
According to GBT50082-2009 " Standard for test methods of longterm performance and durability of ordinary concrete ", carbonization experiment is to cleave test block, then phenolphthalein is sprayed, due to the concrete of carbonization in neutral so phenolphthalein invariant color, and the concrete of non-carbonizing zone presents alkalescence phenolphthalein can be made to present redness due to the existence of calcium hydroxide hole solution, the most just have a demarcation line, then get final product rough measurement carbonation depth with ruler.
Due to directly the lowest by the precision of ruler measurement, the domestic patent of invention also occurring in that some measurement carbonation depths, Chinese patent 88220741.5 discloses a kind of carbonation depth measuring instrument and utilizes lever principle to measure, easily produce error, the relatively low scale division value of certainty of measurement is 0.25mm, maximum range the most about 10mm, then cannot measure for the carbonation depth concrete more than 10mm.
Chinese patent 00233170.5 discloses a kind of carbonation depth dip stick, certainty of measurement is higher, but when carbonation depth is measured, cannot measure for outer little inner big hole, and the rough situation in carbonization face in carbonization experiment, sight angle can produce bigger error to measurement result.
Chinese patent 201010196537.1 discloses a kind of carbonation depth detector, the microlens of setting, lighting source, photographic head, the concrete color situation of change after phenolphthalein spraying can be presented clear, truly, carbonization demarcation line can be accurately found out, it is to avoid the error that stravismus range estimation brings by the image/video of display.Measure quick, simple to operate.There is problems of, generally in imaging theory, photographic head is considered a point, and its image obtained inevitably exists perspective distortion, still has a certain impact for certainty of measurement.
Summary of the invention
