Description

Cultural relic artwork evidence obtaining and verifying point transaction method

Technical Field

The invention relates to the technical field of image data acquisition, in particular to the technical field of artwork scientific record, and particularly discloses a cultural relic artwork evidence obtaining and verifying point intersection method.

At present, the exchange quantity, the transaction quantity and the collection quantity of artworks are increased day by day, a large number of original products come out every day, and a plurality of imitations and counterfeits are continuously appeared, and the artworks relate to cultural and artistic works of various doors such as calligraphy and painting, ceramics, jade ware, bronze wares and the like. Therefore, the collection, record and point transaction of the body information of the artwork in the communication, transaction and collection are bound to become an especially important business. However, the scientific filing and rapid point-delivery service of the artwork, particularly the collection, input, output, evidence obtaining and verification of the artwork body information, must have professional equipment guarantee meeting the service requirements and meeting the professional requirements, and the artwork information all-in-one machine in the invention is professional equipment meeting the service requirements and the professional requirements.

The existing cultural relic artwork evidence-obtaining verification point transaction method comprises the following steps:

firstly, carefully observing the artwork with naked eyes, and shooting the whole image of the artwork by a camera for recording.

Second, several specific locations (also called feature points) are selected on the surface of the artwork, and microscopic images of these specific locations are obtained by microscopic techniques and equipment.

Thirdly, the whole image, the position and the number of the specific point and the corresponding microscopic image are stored in a database.

Fourthly, other related information of the artwork, such as the name of the artwork, author information, creation time and the like, needs to be stored in the database in a matching way.

However, the above-mentioned point handing and filing work is usually accomplished by different people and different equipments at different locations and different times, and the first selection and the second search of the specific position are manually marked and operated, so that it is difficult to clearly mark the specific position and the corresponding relationship between the serial number and the microscopic image and accurately search again. The working efficiency is low, the public confidence is not high, and potential safety hazards and low efficiency are caused to the point-to-point business due to the difference of the business of each operator and each point, the difference of the technology and equipment, and the difference of the steps and the flow. Especially, when a large amount of artworks in a museum and an art gallery are delivered and put in storage, when a large amount of artworks are required to be rapidly checked, verified and checked for transaction, and when an artworks storehouse manager needs to check and hand over works for reasons, errors are easy to occur under the conditions of large workload and time emergency, and the error parts are difficult to find out afterwards due to lack of records in the process of acquiring the microscopic images, so that the public trust of the artworks is reduced, and hidden troubles are brought to future works for checking and handing over works.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments disclosed below.

Next, the present invention will be described in detail with reference to the drawings, wherein the cross-sectional views illustrating the structure of the device are not enlarged partially in general scale for convenience of illustration, and the drawings are only exemplary and should not be construed as limiting the scope of the present invention. In addition, the three-dimensional dimensions of length, width and depth should be included in the actual fabrication.

Referring to fig. 7, an embodiment of a cultural relic artwork evidence-taking verification point transaction method according to the invention is described, which specifically includes the following steps:

step 100, placing an artwork (such as the artwork 8 in fig. 1) on a table top (such as the table top of the table 1 in fig. 1);

step 300, the microscopic image acquisition device is transferred to an artwork microscopic image acquisition position, position data of the microscopic image acquisition device is displayed on a positioning data display screen, the position data comprises X-axis and/or Y-axis and/or Z-axis position data, the X-axis and the Y-axis are located on a horizontal plane where the table board is located, and the Z-axis is perpendicular to the X-axis and the Y-axis;

step 400, acquiring a positioning image by using a positioning image acquisition device, wherein the positioning image comprises position data (namely a data image) displayed in a positioning data display screen, and a position image (namely a state image) of a butt joint state (namely a superposition state) of the microscopic image acquisition device and an artwork, namely a positioning image with the state image and the data image coexisting;

and 500, acquiring a microscopic image of the artwork by using the microscopic image acquisition device. The microscopic image is the microscopic image of the region of interest of the artwork, and the image of the region is used for facilitating evidence collection and verification.

Here, the region of interest may be, in particular, a region on the captured object whose features are distinct and easy to identify. For example, a stamp, an irregular shape, a distinct region from the surroundings, and the like may be used.

Therein, the steps 300, 400, 500 can be performed one or more times sequentially, such that microscopic images of a plurality of different regions of interest (acquisition points) can be acquired.

Any suitable configuration of the microscopic image capture device may be used, as is known to those skilled in the art, so long as the captured image meets the accuracy requirements for forensic verification. As the structures in fig. 4 to 6 can be adopted, the microscopic image capturing device includes the lens positioning device 5 and the third photographing device 4. Alternatively, the microscopic image capturing device may be a third photographing device itself, or the like. The positioning data display screen may take any suitable configuration, for example, the configuration of the second display screen 6 in fig. 1 may be taken. For example, the lens positioning device 5 may refer to any structure for realizing positioning, such as a skirt with positioning marks. The skirt is intended to represent a portion of the bottom edge of the microscopic image capturing device which protrudes outward, and is visualized by this term.

The steps form a precise and orderly process for acquiring the image data. According to the method, the positioning image comprises the position data (data image) displayed in the positioning data display screen, and the microscopic image acquisition device and the artwork butt joint state position image are in a joint state, namely the positioning image with the state image and the data image coexisting does not depend on manual recording, so that the position of the microscopic acquisition device is accurately recorded, and evidence collection and accurate image recording are facilitated. The recording method is scientific and rigorous, improves the credibility of evidence obtaining and recording, and also improves the safety in the recording process, so that the whole evidence obtaining and recording process has the basis of traceability and accountability.

As will be readily appreciated by those skilled in the art, a plurality of sensors are provided to detect position data of the microscopic acquisition device and display the data on the positioning data display screen, which is not described herein and omitted.

Step 200 is included between step 100 and step 300, a feature point on the artwork is selected as a zero point, and the positions of the X axis and the Y axis of the microscopic image acquisition device are adjusted to the zero point. For example, the lower left corner of the work of art may be selected as a feature point, or a feature point on the work of art where other features are clearly conveniently located.

For example, step 200 includes: the method comprises the steps of selecting and calibrating a zero point of artwork positioning by using a cross point of a laser cross line, wherein the laser cross line comprises a transverse line and a vertical line which are vertically crossed, and calibrating the placing angles of the transverse line and the vertical line of the artwork by using the transverse line and the vertical line of the laser cross line, so that the transverse line and the vertical line respectively correspond to the transverse line and the vertical line of the laser cross line, and a digital positioning area capable of being accurately used in a reduction mode is formed on the artwork. At this time, a laser cross-hair emitting device may be provided.

In one embodiment, the micro image capture device is maneuvered into the artwork micro image capture position under the control of the master control device. Therefore, the position of the microscopic image acquisition device can be automatically adjusted through the control of the main control device, so that the microscopic image acquisition device can be positioned at any desired position. Therefore, the speed and the accuracy of evidence obtaining and verification can be improved. Those skilled in the art, given the teachings of this invention, will appreciate the incorporation of various position adjustment mechanisms. Therefore, the description is omitted. Any structure that can adjust the position may be used. Since the position of the microscopic image capture device relative to the artwork is the same at the time of evidence collection and verification, it is important that this position be reached quickly and accurately.

In one embodiment, the user controls the actuator to adjust the microscopic image capture device to the forensic position. Those skilled in the art will appreciate the incorporation of various drive means within the teachings of the present invention. Therefore, the description is omitted. Any structure that can adjust the position may be used.

Some examples of optimized position adjustments are given below.

The above method may be performed using a later described capturing device, in which case the positioning image capturing device may correspond to the second photographing device and the table top corresponds to the horizontal plane of the table 1. Of course, other configurations than those shown in the drawings may be used, and are not limited.

The microscopic image acquisition device is erected above the table board, the positioning image acquisition device is positioned above the microscopic acquisition device, and the relative position between the positioning image acquisition device and the microscopic acquisition device is fixed. Compared with the situation that the two positions are not fixed, the focusing operation of the positioning image acquisition device can be avoided, and the proper shooting parameters such as the focal length are adjusted when the position between the two is determined. In addition, in the whole positioning adjustment process, the two devices move synchronously, the position of the positioning image acquisition device does not need to be adjusted independently, the positioning image can be always acquired accurately without deviation, and the speed of evidence obtaining and verification is greatly improved.

The positioning data display screen is connected with the microscopic image acquisition device, or the microscopic image acquisition device comprises the positioning data display screen. Thus, the two can be moved synchronously throughout the positioning adjustment process.

The main control device is arranged on one side of the table board, and the microscopic image acquisition device and the positioning image acquisition device are connected with the main control device.

The master control device is capable of moving along a lateral slide (e.g., the fourth horizontal slide 14 in fig. 3) under the deck, the lateral slide defining an X-axis direction, in which case step 300 may include: and moving the main control device along the transverse sliding rail so as to adjust the X-axis position of the microscopic image acquisition device. Therefore, the movement of the microscopic image acquisition device is driven by the movement of the main control device.

As shown in fig. 1, a longitudinal slide rail (e.g., the second horizontal slide rail 12 in fig. 1) is connected to the main control device and located above the table top, and the microscopic image capturing device can move in the Y-axis and/or Z-axis direction relative to the longitudinal slide rail, and the step 300 includes: and adjusting the position of the Y axis and/or the Z axis of the microscopic image acquisition device relative to the longitudinal slide rail.

In a more specific example, a vertical rod (e.g., the third vertical slide 13 in fig. 1) is mounted on the longitudinal slide, and a microscopic image capturing device is mounted on the vertical rod. In this example, the microscopic image capturing device is capable of moving up and down in the Z-axis direction along a vertical rod, and step 300 includes: and adjusting the Z-axis position of the microscopic image acquisition device along the vertical rod. Alternatively, the vertical rod can move up and down relative to the longitudinal slide rail, and step 300 includes: and moving the vertical rod to further adjust the Z-axis position of the microscopic image acquisition device.

It is also possible that as shown in fig. 1, a positioning image capturing device (e.g., the second camera 7 in fig. 1) is also mounted on the vertical bar above the microscopic image capturing device and the positioning data display screen (e.g., the second display 6 in fig. 1).

To relieve manpower, the mobile master control device can be implemented by using an X-axis driving device. And adjusting the Y-axis position of the microscopic image acquisition device by using the Y-axis driving device. And the Z-axis driving device is used for adjusting the Z-axis position of the microscopic image acquisition device. In this way, the adjustment can be made more accurate. These drive means may be of any suitable construction and may be mounted at any suitable location and may be readily implemented in accordance with the teachings of the present invention.

For example, by a user operating a movement control (e.g., the movement control 22 mounted on the main control device in fig. 1), the corresponding axis driving device can be activated to achieve the desired position of the microscopic image capturing device. The movable control may be mounted at any suitable location, for example, on the master control device. For example, the movement control may be a button, and by pressing it, the corresponding position may be adjusted.

For example, the main control device may receive position data input by a user and then activate the corresponding shaft driving device, so that the microscopic image capturing device reaches a desired position. For example, an input device (such as a keyboard 21, or a touch screen, a voice input device, etc.) may be provided on the main control device for receiving input from a user. By this, the user can input a desired position coordinate, and the main control device automatically controls the corresponding axis driving device according to the input position.

Of course, a step 220 of acquiring an overall image of the work of art by using the overall image acquisition device may be further included. The whole image capturing apparatus may employ, for example, the first photographing apparatus 3 in fig. 1. The whole image acquisition device can be connected to the main control device, so that the integration level of the whole equipment is improved. If the area of the artwork is too large, the first shooting device is inconvenient to shoot the whole image at one time, the first shooting device can comprise a wide-angle lens, or the artwork is moved to be shot for multiple times and spliced into the whole image.

A display screen (e.g., the first display screen 9 in fig. 1) may be provided on the master device so that the captured image may be viewed and displayed through the display screen thereon throughout the method. This facilitates observation.

The images generated in the process of the method can be partially or completely stored on the main control device, and of course, the main control device can also display the images through a display screen and/or can store the position data of the microscopic image acquisition device.

The main control device can communicate with the microscopic image acquisition device and the positioning image acquisition device, can also communicate with the positioning data display screen, and can also communicate with the whole image acquisition device, which can be realized by the technical personnel in the field under the teaching of the invention and is not described again. Thus, the main control device can perform shooting control on the devices, and can establish images, data transmission and the like between the devices. For example, a menu key corresponding to each of the aforementioned capturing devices may be set on the display screen of the main control device, and by clicking, the corresponding capturing device may be controlled to capture an image, which may be displayed by the main control device and/or stored in the memory thereof.

The master device (which may also be referred to as a host) may be any suitable structure for implementing the present invention. Various structures may be devised to carry out the functions of this invention in light of the above teachings. For example, for ease of installation, it may be in the form of a box structure.

A data output step of outputting (e.g., recording) data in the memory of the main control device onto another storage medium may also be included.

In addition, information such as the name, author, creation time, evidence obtaining place, evidence obtaining record related person, identity information of related personnel, fingerprint information and the like of the collected object (such as an artwork) can be input into the main control device. This may be accomplished by the aforementioned input device or other suitable device.

In one embodiment, full automation of the forensic process may be achieved using the master control device after the artwork is placed on the countertop. At the moment, under the control of the main control device, the automatic adjustment of the microscopic image acquisition devices to the evidence obtaining positions is realized, then under the control of the main control device, each acquisition device shoots to obtain required images, including positioning images, microscopic images and integral images. These images are displayed or stored in the master device. The evidence obtaining process can be carried out for multiple times, and evidence obtaining of multiple collection points of the artwork is achieved. The method greatly improves the speed and accuracy of evidence collection. Of course, semi-automatic operation can also be realized according to the situation, namely, the user can participate. For example, the user may determine the collection point on the artwork desired to be collected, and after inputting the desired position data into the main control device, the main control device adjusts the microscopic image collection device to the position for evidence collection. Or, the user adjusts the microscopic image acquisition device to the position for evidence collection by manually or controlling the driving device.

In the above embodiments, various positioning and adjusting modes are disclosed. It should be understood that these methods can be combined as long as they do not conflict, which further facilitates the acquisition positioning of the microscopic image acquisition device 100, thereby accurately restoring the position of the microscopic image acquisition device 100 in the subsequent verification method.

After image data acquisition, i.e. after storage of a record (forensics), it is necessary to be able to perform a set-up verification of the image again in situ. The method of verifying the image data is as follows.

Step 100, placing an artwork to be verified on a table top;

step 250, acquiring verification position data of the microscopic image acquisition device, wherein the verification positions are positions of an X axis, a Y axis and a Z axis of the microscopic image acquisition device recorded during evidence acquisition and acquisition of the original artwork;

step 300, transferring the microscopic image acquisition device to an artwork microscopic image acquisition position to enable the artwork microscopic image acquisition position to reach a corresponding verification position;

step 400, acquiring a positioning image by using a positioning image acquisition device, wherein the positioning image comprises position data displayed in a positioning data display screen and a position image of a butt joint state of the microscopic image acquisition device and an artwork, namely a positioning image with the state image and the data image coexisting;

500, acquiring a microscopic image of the artwork by using the microscopic image acquisition device to serve as a microscopic image for verification;

step 600, comparing the microscopic image for verification with the microscopic image acquired during evidence collection of the original artwork, and determining whether the artwork to be verified is the original artwork based on the comparison. Here, the determination may be performed by a device having an image comparison function (such as a main control device or other electronic equipment), or may be performed manually by a verification professional.

In step 250, the verification location data may be obtained from a positioning image captured during forensic acquisition of the artwork original. If when collecting evidence to the work of art original paper, when shooting the location image, master control set has also stored verification position data at that time, also can call out the verification position data of storage at that time from master control set.

In the verification, step 300 may include the master control activating the X-axis and/or Y-axis and/or Z-axis driving means according to the verification position data, thereby bringing the microscopic image capturing device to the verification position. Therefore, the micro image acquisition device can automatically reach the verification position without manual participation, so that the verification is quick and accurate, and the verification efficiency is greatly improved.

Alternatively, step 300 includes the user operating the motion control to activate the X-axis and/or Y-axis and/or Z-axis drive according to the verification location data to bring the microscopic image capture device to the verification location.

In one embodiment, after the artwork is placed on the countertop, full automation of the verification process can be achieved using the master control device. At this time, the main control device automatically retrieves the positioning image, and analyzes the position data included in the image as the verification position data. Of course, this data can also be called directly if the master also stores the individual verification location data at the time of the forensics. Then, the microscopic image acquisition device is automatically adjusted to the verification position under the control of the main control device. Then, each acquisition device shoots under the control of the main control device to acquire required images, including positioning images, microscopic images and integral images. Then, the main control device can also compare the microscopic image obtained in the evidence obtaining process with the microscopic image obtained in the verification process, and draw a conclusion whether the artwork to be verified is the original or not according to the comparison. Of course, some of the steps may be user-initiated, as described above in the forensics.

Of course, step 220 may also be included to obtain a whole image of the work of art using a whole image capture device (such as the first camera described above). The position of the whole image acquisition device can also be adjusted.

The key point during verification is that the microscopic image acquisition device is restored to the same spatial position as the spatial position of the artwork original during evidence collection, and the position of the microscopic image acquisition device can be restored by using a similar method of position adjustment during the original evidence collection.

The microscopic image acquisition device can be used in original acquisition and can also be a microscopic image acquisition device of the same product type. The verification can be performed at different time and place. The microscopic image acquired during the evidence collection of the original artwork can be stored in the original master device or data transferred to other media such as a separate database and the like by the original master device.

It is also possible to record all the collected images (such as microscopic image, positioning image, whole image), various data (such as microscopic image collection device position data, name of the collected object, author, creation time, location of evidence collection, person relevant to evidence collection and filing, identity information of author or person relevant to evidence collection and filing, fingerprint information, etc.) into a storage medium (such as optical disc, etc.). Physically sequestered closed delivery (which may be physically sequestered closed delivery under lawyer witness) and third party storage and verification are then performed. Is convenient for judicial intervention and case breaking. The recording can be carried out at the same time of evidence collection and verification, or can be carried out later.
