Abstract
The invention relates to an identification method, particularly to a lossless furniture identification method which comprises the following steps: using a handheld digital microscope to shoot pictures of the frontage cross section, the frontage tangential section and the frontage radial section of a furniture component, and comparing the pictures with reserved wood samples, wherein shooting points on the frontage cross section, the frontage tangential section and the frontage radial section of the furniture component are selected before shooting, and all the shooting points are smeared with an immersion oil. Compared with the prior art, the lossless furniture identification method has the following substantive features and remarkable advancements: the integrity of furniture can be protected with no sampling and flaking required while performing furniture identification; the identification method is simple in steps, easy to operate and suitable for the masses; through the immersion oil smeared on the shooting points, the shot pictures have higher sharpness and the requirement for identification can be met.
Description
Technical field
The present invention relates to a kind of authentication method, relate in particular to a kind of Nondestructive Identification method of furniture.
Background technology
Traditional wood identification method is that macrofeature and microscopic feature are combined, and by observing, compare, analyzing, can identify the seeds of timber.First its process will intercept the wooden sample of certain size size on identified article, then free-hand section or microtome cut out the thin slice of square section, tangential section and radial longitudinal section from timber, make interim section or forever section, be placed in its internal structure feature of optical microphotograph Microscopic observation; In conjunction with both macro and micro feature, with reference to the books of relevant timber identification, describe and check, tentatively judge result, then contrast with sample collection wood and section, finally make result.Traditional timber is identified and need to be sampled article, will cause certain destruction to furniture, the slice size of timber sampling is 10mm * 5mm * 5mm, conventionally the square section of size does not comprise a complete growth ring like this, observing its square section microstructure characteristic, there is certain limitation.
The people such as Li Minhua are by hand-held digital microscope, adopted a kind of authentication method of surface nondestructive, but the microcosmic picture clarity that the photo of shooting is taken pictures out with respect to section statining is slightly poor, just basic satisfied evaluation requires (Li Minhua, the ancient cabinet-wood Nondestructive Identification of the < < method research > > that Tan Biming etc. deliver, include in Xibei Forest College's journal 2012,27(6); 165～167).
Summary of the invention
A kind of Nondestructive Identification method that the object of this invention is to provide furniture, object of the present invention is achieved through the following technical solutions:
A kind of Nondestructive Identification method of furniture, by the positive square section of hand-held digital microscope photographing furniture component, positive tangential section, positive radial longitudinal section picture, compare with collection wood sample sample and section, wherein: before taking in the positive square section of furniture component, positive tangential section, positive radial longitudinal section surface get shooting point, in each shooting point, be coated with and spread immersion oil.
Preferably: it is 4 that the shooting point that positive square section, positive tangential section, each face of positive radial longitudinal section surface are got is counted, and the spacing distance of shooting point is 3～5cm.
Preferably: the refractive index size of the immersion oil of smearing in described shooting point is followed successively by:
1.3≤first shooting point immersion oil refractive index≤1.4,
1.4 second of < shooting point immersion oil refractive index≤1.5,
The 3rd shooting point immersion oil refractive index≤1.6 of 1.5 <,
The 4th shooting point immersion oil refractive index≤1.7 of 1.6 <.
Preferably: described immersion oil smearing thickness is 1～2mm.
After shooting finishes, pick out positive square section, positive tangential section, the positive the highest picture of radial longitudinal section sharpness, judge the concrete timber varieties of trees of furniture.
Compared with prior art, its substantive distinguishing features and marked improvement part are in the present invention:
1, the present invention does not need to sample film-making when identifying furniture, can protect the integrality of furniture;
2, step of the present invention is simple, and easy operating is applicable to popular a kind of detection method;
3, the present invention is by smearing immersion oil, and the picture clarity of taking is out high, can meet the needs of identifying.
