State of the art

At the present stage of the development of science and technology, the use of three-dimensional models, which make it possible to demonstrate real objects from different angles. Until now, volumetric models have been built exclusively with the help of special programs - 3D modeling. However, pretty soon, this complex and high-tech method was the creation of three-dimensional models based on two-dimensional information - photographs. This option for generating three-dimensional models has become a promising direction and has contributed to the emergence of new developments in three-dimensional shooting systems and three-dimensional representation of objects.

For example, a three-dimensional laser scanning system is known, including a three-dimensional laser scanning station (scanner) and special software that allows one to obtain a three-dimensional model based on processing the scanning results of a single photograph of an object or area [see information about the three-dimensional laser scanning system Scanstation 2. Electronic resource: http://www.incom-iic.ru/laser.htm].

The main disadvantage of the known three-dimensional laser scanning system is its complexity and high technology, as well as the long duration of the process of generating three-dimensional models and the too high cost of equipment.

Also known is a system for acquiring images for generating three-dimensional visualizations of improved quality, consisting of equipment and software, in this case, includes a collapsible base, made in the form of a frame structure represented by a supporting beam and several supports adjustable in height, cameras, the optical centers of the lenses of which are located on the indicated support mainly in two rows with the rows offset relative to each other in mutually perpendicular directions, a synchronization subsystem for synchronous operation of all cameras, equipped with a control transmitter and receiver with a synchronizer, connected to a source of pulses full light and connected to the system via wireless communication, the processing unit for the received data in the form of a computer with special software installed and also a device for printing the results [see US Pat. Russia Ns 99199 for class G02B 27/22, published on November 10, 2010 in Bull. N ° 31].

The main disadvantage of this known system is the rather low reliability of failure-free operation due to the presence of a large number of sophisticated equipment, as well as the absence of any devices to facilitate the shooting process and improve the quality of the obtained images, as well as the imperfection of the method Submission of captured images. The listed disadvantages are due to the following. Firstly, in accordance with the declared technical The solution consists of at least 16 cameras, equipped with a special mount and installed in two rows on a bulky collapsible basis, as well as the availability of additional memory cards, wireless communications (Bluetooth, Wi-Fi) and a complex device for synchronizing the cameras , which, in aggregate, significantly complicates and increases the cost of organizing photography and creating three-dimensional images. Secondly, the way of representing captured objects in three-dimensional space is imperfect, and more precisely: the known system provides for the printing of three-dimensional models on paper, which does not allow to fully reveal all the visual advantages of the resulting digital production.

The closest in essence and achieved effect, taken as a prototype, is a system of three-dimensional shooting and presentation of an object in three-dimensional format, containing equipment consisting of a camera for obtaining a series of images of an object in different angles, a calibrating stand, in the center of which the shooting object is placed , and a computer with preinstalled special software for building a three-dimensional model and exporting it to one of the well-known ЗР-formats [see 3D Software Object Modeller software product information (developed by Creative Dimension Software Ltd). Electronic resource: http://www.3dsom.com].

The main disadvantage of this known system is the lack of any devices in its composition to facilitate and speed up the shooting process, as well as improve the quality of the obtained images. This disadvantage is explained by the following. In accordance with the stated technical solution, to create a three-dimensional model, you must first get about 20 pictures of the selected object in different angles, while the quality of the finished product (3D model) directly depends on the results of photography, and the stage of creating photographs is quite time-consuming and responsible, and without special equipment it is very difficult to achieve that with the selected aperture, all the captured frames were in focus (it is necessary to strictly maintain the distance from the camera to the subject and at the same time live the same angle of circular rotation of the camera).

The next, no less important, drawback of the known system is its low technical capabilities, which is due to the limited functionality of its individual nodes. This drawback relates to the design of the calibrating stand and consists, in particular, in the following. This technical solution must A prerequisite for shooting is the location of the object in the center of the calibrating stand, which is played mainly by an ordinary white sheet of paper of the appropriate size with markings applied on it, which is necessary for normal recognition of the captured object by the program. With the help of this stand, the imperfection of the software is only compensated during the processing of the obtained images, while it does not in any way affect the process of shooting itself and does not contribute to improving the quality of its results.

Another significant drawback of the known system is that the camera is not connected to a computer. This drawback does not allow you to quickly and automatically process the results of photography and immediately place the finished product on web pages on the Internet.

Thus, the well-known system for three-dimensional shooting and presentation of an object in three-dimensional format is complex, besides with limited functional capabilities, and it requires a lot of time and professional skills in photographing and programming.

The basis of the invention is the task of improving and simplifying the system of three-dimensional shooting and presentation of the object in in a three-dimensional format due to the possibility of accelerating the operation of the system and improving the quality of intermediate photographic materials by changing the principle of positioning of the subject relative to the camera, the principle of their processing and presentation on the Internet.

SUMMARY OF THE INVENTION

The solution of this problem is achieved by the fact that in the well-known system of three-dimensional shooting and presentation of the object in three-dimensional format, containing equipment consisting of a camera for obtaining a series of images of the object from different angles, a calibrating stand in the center of which the object is located, and a computer with a special software software for building a three-dimensional model, according to the proposal, the calibrating stand is made in the form of a horizontally oriented rotating platform, the camera is connected to through a programmed control unit that synchronizes the camera response frequency with the platform rotation speed, and a special software product converts a series of two-dimensional images into one three-dimensional (volumetric) moving photograph, which is a digital pseudo-three-dimensional model of a real object. The location of the subject on the proposed rotating platform can significantly simplify and reduce the time the process of photographing the subject, and also provides high quality photographs, as it guarantees a stable position of the camera relative to the subject of photographing, regardless of camera angle. The presence of a programmed control unit in the system makes it possible to optimize the processes of photographing, processing the captured material and constructing pseudo-three-dimensional models. The direct connection between the computer and the camera allows you to quickly convert captured objects in three-dimensional format and place them on the Internet.

Thus, the entire set of essential features of the claimed object of technology obtained as a result of making appropriate changes to the process of obtaining pseudo-three-dimensional photographs of photographing objects, together with a special software product, ensures the achievement of a certain positive technical result, formulated in the statement tasks.

The list of figures illustrative materials

The further essence of the proposed technical solution is clarified in conjunction with illustrative material on which The general scheme of the proposed complex of equipment for three-dimensional shooting and presentation of the object in three-dimensional format is shown.

Description of a preferred embodiment of the invention

The proposed universal Mamagi system for three-dimensional shooting and presentation of an object in three-dimensional format contains a camera 1, a control unit 2, and a rotating platform 3. The camera 1, mainly by cable communication, is connected to a computer 4.

The proposed universal system "Mamagi" for three-dimensional shooting and presentation of the object in three-dimensional format is used as follows.

Representation of a specific object in digital three-dimensional format involves photographing it with further generation of the corresponding three-dimensional model. To do this, the selected object is placed on the surface of the rotating platform 3 and using the camera 1 perform a series of photographs. When photographing an object, the indicated platform 3, rotating around its axis, changes the angle of the object mounted on it relative to the camera lens 1 (for one full revolution of the platform 3 360 ° the object is photographed from all sides). Process management photographing is carried out using the software installed on the computer 4. In this case, the synchronous operation of the camera 1 and the rotating platform 3 is ensured by the programmed control unit 2. The obtained photographs of the object are quickly processed using the appropriate computer program and in the appropriate format (Macromedia Flash (swf) or a set of JPEG files) is uploaded to a selected web page on the Internet.

Thus, the use of the proposed universal Mamagi system allows in just a few minutes to obtain a high-quality three-dimensional image of the object and present it on the site without special photography and programming skills.

The claimed technical solution is tested in practice. The proposed universal Mamagi system for three-dimensional shooting and representation of an object in three-dimensional format does not contain a single structural element or software that could not be created at the present stage of development of science and technology, in particular, in the field of three-dimensional technologies, therefore, is acceptable for industrial use, has technical and other advantages over known analogues, which confirms the possibility of achieving technical result of the claimed object. In well-known sources of patent and other scientific and technical information, there are no systems for three-dimensional shooting and presentation of an object in three-dimensional format with the set of essential features specified in the proposal, therefore, the proposed technical solution is considered such that it can receive legal protection.

A significant difference between the proposed universal Mamagi system for three-dimensional shooting and representation of an object in three-dimensional space from previously known similar technical solutions is that the calibrating stand is made in the form of a horizontally oriented rotating platform, the camera is connected to a computer to ensure the rapid receipt of three-dimensional digital models and their placement on the Internet, as well as in the presence of a programmed control unit that connects the calibration stand with a computer Ohm and thus allowing you to control the shooting process. These differences, in total, provide an opportunity to quickly and easily obtain high-quality pseudo-three-dimensional digital models of any object and quickly place a three-dimensional image on any web-sites. None of the known photosystems for three-dimensional shooting and representing an object in three-dimensional format can simultaneously possess all of these properties, since they generally do not include in their composition the entire totality of the essential features declared in the proposal.

Since the above-mentioned properties are not obvious to specialists in this field of knowledge and cannot generally come up from the existing level of technology, it can be concluded that the proposed technical solution meets the criterion of "inventive step".

Technical Advantages of the Invention

The technical advantages of the proposed universal Mamagi system for three-dimensional shooting and representation of an object in three-dimensional format, compared with the prototype, include the following:

- providing the ability to simply and quickly obtain high-quality volumetric photographs by equipping the system with a rotating platform and a software control unit for it;

- providing the ability to quickly process the results of three-dimensional surveys and post them on the Internet due to the direct connection of the camera with the computer;

- expansion of functionality and usability due to automation of all processes and lack of need skills in photography and programming.

The economic effect of introducing the proposed technical solution, in comparison with the use of the prototype, is obtained by reducing the cost of generating volumetric images in the form of pseudo-three-dimensional digital models in a simple way using conventional and common equipment.

The social effect of the implementation of the proposed technical solution, in comparison with the use of the prototype, is obtained due to the possibility of filling sites with a new kind of volumetric and high-quality product.

After describing the proposed universal Mamagi system for three-dimensional shooting of the presentation of the results in three-dimensional format, it should be obvious to specialists in this field of knowledge that all of the above is only illustrative and not restrictive, as presented by this example. Numerous possible options for the implementation of this system, in particular, ways of organizing communication between individual components of the equipment, changing the drive and the design of the rotating platform, can vary depending on the specifics of its use and, of course, are within the scope of one of the usual and natural approaches in this field of knowledge and are considered such that are within the scope of the proposed technical solution.

The quintessence of the proposed technical solution is the implementation of a calibrating stand in the form of a horizontally oriented rotating platform, in the connection of the camera with a computer, and also in the presence in the system of an additional software control unit connecting the platform to the computer, and these are the circumstances, taken together , allowed us to purchase the proposed universal Mamagi system for three-dimensional shooting of the presentation of results in three-dimensional format, the above and other advantages. The use of individual structural elements and components of the equipment from the totality declared, naturally, limits the range of advantages listed above, and cannot be considered new technical solutions in this field of knowledge, since other structures, such as described, are no longer require some kind of creative approach from designers and engineers, and cannot be considered the results of their creative activity or new intellectual property objects that are appropriate for the protection of security documents in accordance with applicable law.
