Description
[technical field]
The present invention relates to a kind of endoscopic system, refer in particular to a kind of endoscopic system, relate to a kind of measuring method of this system simultaneously with measurement function.
[background technology]
Previous sight glass does not possess measurement function, no matter is rigid sight glass or soft sight glass, when observing object, visual angle decision by necessity, nearly big, far away little parallax occurs, this parallax makes endoscope can only observe the shape of object qualitatively, and size that can not quantitative mensuration object.
So, just have many scientist's research to have the sight glass of measurement function as far back as the eighties.Known to the inventor, in China Patent No. is that 86101466 patent text has been put down in writing a kind of " have and measure endoscope and measuring method thereof ", measurement of the present invention endoscope, belong to the technological improvement of endoscope, as shown in Figure 1, being characterized in setting up on conventional endoscope one comprises by surveying chi 1 ', the measuring system that graticle 2 ' constitutes, surveying chi 1 ' is arranged in the survey chi handle hole 10 ', graticle 2 ' indicates the delineation hurdle or groove is drawn in the size segmentation, its measuring method is to utilize the inherent angle of visual field 2W of endoscope, object distance L, the H/L=W2TG relation that exists between the dimension of object H comes the distance of Measuring Object big or small.Have in the routine open source literature under also having in addition and mention other various endoscopies with measurement function.
China Patent No. is to disclose a kind of " fibrescope dip stick " in 86209992 the document, by means of endoscope the focus size of human body gastral cavity (or enteric cavity) is measured, its feature adopts novel dip stick, form by operation, guiding, three ones of measurements, by the thumb snare, scale is opened or closure, can finish focus and measure.Its advantage be easy to use, measure accurately, directly perceived, be fit to various chambeies mirror and be equipped with and use.
China Patent No. is to disclose a kind of " endoscope measuring rule " in 93227151.0 the document, it is made up of chi handle and blade, its technical scheme is to be provided with the fixing snare that refers in chi handle upper end, be connected with blade in chi handle lower end, on chi handle front, have the bar shaped groove and be provided with graduated disc, respectively have a bar shaped groove respectively in chi handle both sides, on its both sides bar shaped groove, respectively be provided with a slip respectively and refer to snare, two slips refer to that the snare end all respectively is connected with an elastic wire chi respectively, and two elastic wire chis stretch out at blade end two angling holes by the blade internal diameter.It can measure the size of different shape focus, and measures accurately, and error is little, by size variation before and after the focus treatment, but observe the curative effect, estimating prognosis.
China Patent No. is to disclose " a kind of self-focusing endoscope that can measure " in 98113022.4 the document, the self-focusing endoscope that this endoscope can measure, it constitutes the sight glass sheath, passes light beam, the coupled relay lens rod of image-forming objective lens and its rear end, on the coupling surface of described image-forming objective lens and relay lens rod, be shaped on division line, and be shaped on master scale at the sight glass jacket outer surface.In conjunction with the measurements and calculations method that is provided, it not only can be used for observing the shape of inner chamber object, and the size of the observed object of energy measurement, for the staff provides more reliable data, information, and have characteristics such as simple in structure, that making is easy, easy to use, be suitable for the use of industries such as medical treatment, building, police reconnaissance.
From above-mentioned documents as can be seen, the major defect of prior art is: 1, obtain pass amplification or pixel physical size ratio as parts as parts to the distance between the object of observation owing to can't measure biography, so can only qualitative observation.2, owing to be subjected to the restriction of science and technology at that time, measuring system in endoscopic system adopts mechanical parts such as surveying chi, graticle to measure substantially, the formula of substitution as a result that need will record, by calculating the size that could obtain testee, can not when measuring, obtain the size of testee automatically again.3, the most important point is, does not all have the open distance that how to obtain between testee and the observation parts in the prior art, also just makes when practical operation, owing to the definite distance of not learning between the two, and causes maloperation.
