Description

Method for verifying existence of purple sand works made of Huanglongshan purple sand pug and special server

Technical Field

The invention belongs to the field of purple sand works, and particularly relates to a method for verifying whether purple sand works made of Huanglong mountain purple sand pug exist or not and a special server.

Background

Yixing purple sand is a special product in Yixing city in Jiangsu province, and a geographical sign product in China. The Yixing purple sand teapot is made of purple sand mud which is made of purple sand ore and is originally produced in Huanglongshan of Yixing Shuzhen of Jiangsu, so that the Yixing purple sand pot is named as Huanglongshan purple sand. 12 and 23 in 2013, the former national quality inspection administration approves the geographical marking product protection on Yixing purple sand.

Purple placer is an original material for manufacturing purple sand vessels, is a general name of purple mud ore, green mud ore and red mud ore and is iron-rich silty rock. The high-quality purple placer is generally hidden under the bottom of the 'Huanglongshan' stone rock and distributed in multiple layers, including purple mud ore, green mud ore and other varieties, and the red mud ore is located on the shallow surface layer under the rock. Purple placer ore is manually selected from many mined ore materials, and is called mud in mud and rock in rock.

The price of the purple clay teapot is different, and the hand skill of the purple clay craftsman really distinguishes the sale price under the condition that the price of the purple clay raw materials is almost the same. At present, after the purple sand artware finishes the works, the bottom of the purple sand pot is usually covered with a private seal to prove the authenticity of the purple sand pot, but some speculators can copy by utilizing a false private seal and imitating an original pot shape to fulfill the aim of falsely and falsely, including that the purple sand artware is difficult to distinguish the authenticity at any time; moreover, some purple sand artists can imitate the purple sand teapot by an apprentice and then cover the imitated purple sand teapot with private badges, so that the continuous badges are true and are more difficult to distinguish by purchasers. In view of the above situation, the industry now has such mishaps: when the dark-red enameled pottery is circulated, the author is matched with a self-written certificate, and the certificate is a genuine certificate which means that the dark-red enameled pottery cannot be provided. However, aiming at the situation, a speculator can divide the dark-red enameled pottery and the certificate, namely, one imitated teapot is sold together with the real certificate, then the authentic dark-red enameled pottery is held and found out that the dark-red enameled pottery is sold by other borrowers and then the authentic dark-red enameled pottery is issued again, so that the situation is disturbed, the dark-red enameled pottery is an authentic product, and the dark-red enameled pottery is often issued with an authentic certificate again. Therefore, the cost of buying a house is high, and only fake purple clay teapots can be obtained.

Disclosure of Invention

The invention aims to: the invention aims to provide a method for verifying whether purple sand works made of Huang Long shan purple sand pug exist or not aiming at the defects of the prior art.

The invention also discloses a special server for the method for verifying whether the purple sand works made of the Huanglong mountain purple sand pug exist.

The technical scheme is as follows: in order to achieve the above object, the present invention is specifically accomplished by: a method for verifying whether purple sand works made of Huanglong mountain purple sand pug exist or not is disclosed, wherein after the firing of the purple sand works is finished, parts of the purple sand works with different color points are selected for shooting, and shot pictures of the purple sand works are stored on a server; when verification is needed, different color points of the reserved photos on the corresponding server of the purple sand works to be verified are compared, if the different color points are the same, the same purple sand works are judged, and if the different color points are not the same, the same purple sand works are judged.

According to a preferable scheme, after the purple sand works are fired, the part of the purple sand works with more than two different color points is selected for shooting; this is because since a single heterochromatic point is common, a collection of heterochromatic points is preferred as much as possible for reference when choosing.

On the basis of the preferred scheme, the area of the part of the purple sand work where more than two different color points exist is not more than 2cm multiplied by 2cm; this is to further define the footprint of the set of heterochromatic points so that the observer can better perform subsequent alignments.

According to another preferred scheme, after the purple sand works are fired, selecting a part of the purple sand works with different color points for shooting, counting the positions of the different color points on the shot purple sand works photos, and recording the photos and the positions of the different color points on a server; when verification is needed, photos with the same position and size are made at the position, corresponding to the server photo, of the purple sand work to be verified, the positions of the different color points of the photos are compared, when the positions of the different color points are consistent with the recording position of the server, the same purple sand work is judged, otherwise, the same purple sand work is judged; the aim of this is to verify, on the one hand, the presence of the metachromatic points and, on the other hand, to verify the location of the metachromatic points, a double verification completely precluding the possibility of imitation.

On the basis of the preferred scheme, the purple sand works are fixed, then photos are shot, a plurality of different color points are selected from the photos for statistics, the lengths and the heights of the different color points on the photos are respectively counted, and then the length and the heights of the different color points on the photos are recorded to a server; the advantage of doing so lies in follow-up when comparing, makes things convenient for operating personnel to carry out complete restoration to the red porcelain works photo that follow-up took, imitates the problem of heterochrosis point coordinate skew because of shooting the angle brings.

On the basis of the preferred scheme, the violet sand works are edited by adopting Photoshop software after photos are taken, and the length and the height of the captured heterochromatic points are measured; therefore, the positioning error caused by software factors can be avoided by the aid of mature software.

On the basis of the preferred scheme, the usage position of the purple sand work is fixed, and then the front projection surface of the usage position is used for shooting; this can further reduce the contrast error generated in the subsequent verification.

On the basis of the preferable scheme, the photo of the purple sand work is rectangular, the length direction is used as a horizontal axis, the width direction is used as a vertical axis, and the horizontal axis data and the vertical axis data are recorded simultaneously when the same different color point is captured.

On the basis of the preferred scheme, when the different color points are compared and verified, the error of the horizontal axis data of the different color points in the two times is not more than 1% of the length of the photo, and the error of the vertical axis data of the different color points in the two times is not more than 1% of the width of the photo; the design can better scientifically and effectively avoid human errors in the operation process.

A server special for verifying whether purple sand works made of Huanglong mountain purple sand pug exist or not comprises software for recording the photos of the purple sand works.

The principle of the invention is as follows: when the Huanglongshan purple sand ore is refined into the purple sand mud, the purple sand mud is prepared by either a plurality of mineral aggregates or a single mineral aggregate. In the first case, different small particles of mineral aggregate can be in different colors after being fired; in the second case, because single mineral aggregate is not completely pure, impurities such as other mineral aggregate components or iron and the like are mixed to different degrees, and after the mineral aggregate is fired, small particles or impurities of other mineral aggregates are also shown certainly. Therefore, the purple sand works made of all kinds of Huang Longshan purple sand pugs are certainly not in one color after being fired, and more or less purple sand small particles or impurities with different colors are mixed. The distribution of the 'heterochromatic particles' is random and cannot be copied, so that the 'anti-counterfeiting' method selects the heterochromatic particles as a reference object to perform 'anti-counterfeiting'.

Has the advantages that: compared with the prior art, the invention has the following advantages:

(1) The method has scientific design and ingenious conception, catches the different-color particle distribution condition which seems to be irregular and can be circularly distinguished from the natural color, and in fact, the possibility of catching and counterfeiting is completely eradicated due to the uniqueness of the distribution of the different-color particles;

(2) The invention carries out positioning capture on the photo of the purple sand works, has simple operation and high feasibility, and can avoid the situation that the consumer is deceived by adopting imitation in the market of the purple sand teapot.
