The beam irradiation that the light source module of device 160 is sent is rotated by 360 ° in article surface with preset angle speed control turntable 151
To cause article to rotate with 360 degree, while during article rotating, control data harvester 160 is with default sample rate
Gather the spectral information and image information of article surface.Further, data acquisition device 160 is adjusted by hoistable platform 170
Height so that data acquisition device 160 scans the spectral information and figure of article surface at different height in the manner described above
As information, so as to obtain the spectral information and image information of whole article surface and send to control device.Control dress
Put and the image information of reference spectra information, the spectral information of article to be measured and article to be measured is handled, judge that this is to be measured
The true and false of article.
In the utility model embodiment, control device to reference spectra information, the spectral information of article surface to be measured and
The image information of article to be measured is handled, and judges that the embodiment of the true and false of the article to be measured can be as：According to benchmark
The spectral information of spectral information and article surface to be measured obtains the spectral reflectivity of article surface to be measured；By resulting determinand
The spectral reflectivity of original product of the spectral reflectivity of product with corresponding to the article to be measured in demarcation storehouse is matched；According to be measured
The image information of article surface obtains the three-dimensional space shape information of article to be measured；Believed according to the three-dimensional space shape of article to be measured
Breath carries out three-dimensional reconstruction to article to be measured, obtains the three-dimensional configuration data of article to be measured；By the three-dimensional configuration data of article to be measured
Matched with the three-dimensional configuration data of demarcation storehouse Central Plains article；If the spectral reflectivity and the three-dimensional configuration number
According to the match is successful, then judge that the article to be measured is consistent with the original product；If it fails to match or three-dimensional for spectral reflectivity
It fails to match for morphological data, then judge that article to be measured and original product are inconsistent.
Specifically, the spectral energy of standard white plate reflection can be obtained according to reference spectra information, as the first light
Spectrum energy data.Because the spectral information of article surface to be measured is data acquisition device 120 or data acquisition device 160 to be measured
Article surface, which is scanned, to be obtained.Therefore, scan position correspondence can be obtained according to the spectral information at each scan position
Each coordinate points at reflectance spectrum energy, be used as the second spectral energy data.Based on this, according to reference spectra information and to be measured
The mode that the spectral information of article surface obtains the spectral reflectivity of article surface to be measured can be：Obtained according to reference spectra information
To the first spectral energy data；Second spectral energy data are obtained according to the spectral information of article surface to be measured；By the second spectrum
Result after energy datum divided by the first spectral energy data, which is multiplied by reference reflectance, can obtain the light of article surface to be measured
Compose reflectivity.
Wherein, reference reflectance is the spectral reflectivity of above-mentioned standard blank, can be pre-stored within control device,
It can also input in real time.For the light of different wave length, the reflectivity of standard white plate slightly has difference, but difference is smaller, can ignore.
It should be noted that original product can be to be accredited as the valuables such as historical relic, the art work of genuine piece, can also
To lend to other people article.The detecting system 10 that the utility model is provided can detect whether article to be measured is original product, i.e.,
Detect that article to be measured is genuine piece, or imitation.For example, certain buyer wants one width oil painting of purchase, the oil painting is stated to be certain work
The width famous painting of celebrated painter, now, original product represent the genuine piece of the oil painting, and article to be measured represents current oil painting to be purchased.Again
For example：Zhang lends article A to Lee, and after a period of time, article A' is returned to Zhang by Lee, now, and article A is then
Original product, article A' is then article to be measured.
It is understood that the acquisition of the spectral reflectivity of the original product corresponding to the article to be measured stored in demarcation storehouse
Method is identical with the acquisition methods of the spectral reflectivity of article to be measured, and the data of required collection are to be provided by the present embodiment
Detecting system 10 obtain.In addition, the three-dimensional configuration data of the original product corresponding to the article to be measured stored in demarcation storehouse
Acquisition methods are identical with the acquisition methods of the three-dimensional configuration data of article to be measured.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
