The invention relates to the technology of augmented reality providing representation as environmental objects, and various artificial elements that serve, for example, to identify these objects.

As the closest analogue of the invention is selected how to display the environment described in the application for the grant of a patent on invention USA US 2011153198, published on 23.06.2011. According to well-known from US 2011153198 the display method of the environment through the camera or smartphone get the picture environment, mainly dynamic image. Determine a spatial position and/or direction of movement of the means of obtaining images according to several of spatial positioning: GPS receiver at least one satellite positioning system and an electronic compass. Compare the resulting image with three-dimensional models of the environment and electronic maps or plans, identify objects in the environment, which is part of the image, on the basis of the above information and complement the acquired image of the environment at least one visually perceptible artificial element, reflecting the results of identification of environmental objects.

<> The disadvantage of this method is the impossibility of environmental analysis in real time, which can lead to incorrect addition of images of artificial objects. In addition, there is a method of display environment does not account for dynamic changes in the environment associated with weather conditions, anthropogenic landscape changes, etc.

In turn, we offer you a way to display the environment will allow the environmental analysis in real time, taking into account dynamic changes in the environment caused by natural phenomena.

This technical result is achieved in the practical use of the display environment, which includes obtaining the appropriate means of depicting the environment, determination of the spatial position and/or direction of means of obtaining images according to several of spatial positioning, such as GPS receiver at least one satellite positioning system. The resulting image map with three-dimensional models of the environment and electronic maps or plans and identify objects in the environment, which is part of the image on the basis of the listed you the e information. As a result, the image of the environment complementary to at least one visually perceptible artificial element, reflecting the results of identification of environmental objects.

According to the proposed invention during display ambient determine the current time and take into account the state of the atmosphere based on available funds, selected from the list: the quality of the obtained image of the environment, current time information, a database of meteorological elements. The spatial position and/or direction of movement of the means of obtaining the image determined according to at least two accessible means of spatial positioning, selected from the list: the navigation receiver of at least one satellite positioning system, accelerometer, electronic compass, Analytics, location in a cellular network. The resulting image map with three-dimensional models of the environment and e-cards or plans stored in the corresponding dynamically updated knowledge base. When using the proposed method in urban areas receive the image of the urban landscape, and referred to the knowledge base contains information about the location of objects of city infrastructure, including information which the Oia about the signs, inscriptions, signs and road signs, and the database of meteorological elements contains information about the climate. When using the proposed method indoors get a picture of the interior, and referred to the knowledge base contains information about finish, setting, and location of equipment, furniture or other interior elements.

The environment, which is part of the image, identified on the basis of the above information using learning artificial neural network associated with the said knowledge base, and Supplement referred to the knowledge base with new information obtained as a result of such identification. For the most efficient use of the proposed method mentioned knowledge base contribute new information coming from a variety of custom tools obtaining images of the environment.

The proposed method is as follows.

To obtain images of the environment (shooting) can be used any known means 1 for receiving and managed image processing, mobile communication terminals equipped with video cameras (smartphones, PDAs and the like), a stationary programmable terminals associated with remote video cameras. It is obvious that in most case the EB such means 1 will be used to obtain dynamic video if possible, get snapshot photos.

Simultaneously with the image acquisition is performed a comprehensive analysis of the conditions under which it was obtained this image. Using timer 2 of the communication terminal or the video camera 11determines the current time (time of day, calendar date). The spatial position and/or direction of movement of the means of obtaining the image, that is, the position of objects in the line of sight, determined according to several (at least two available based on shooting conditions) of spatial positioning. Part of these funds to the spatial positioning includes: a navigation receiver at least one satellite positioning system (Navstar GPS, GLONASS, Galileo, Beidou, IRNSS) 3, the accelerometer 4, e-compass 5, Analytics, location in a cellular network (LBS) 6. Thus, even when the loss of signal from the satellite positioning systems and/or analysis tools location in a cellular network, according to the accelerometer 4 and the electronic compass 5 will be determined by the direction of movement of the means of obtaining image 11and, accordingly, will be determined by the position of the objects in the line of sight and stored allowing for positioning data in the identification of objects surrounding the Reda. In favorable conditions, providing 3 reception signal from a satellite positioning systems and analysis tools location in the cellular network 6 and the operation of the accelerometer 4 and the electronic compass 5, will be provided as an exact determination of geographical coordinates (latitude and longitude), and precise determination of the direction means of obtaining image 11. In any case, the joint use of the above tools spatial positioning will eliminate the loss of spatial orientation means of obtaining the image and, therefore, incorrect identification of environmental objects.

At the same time based on the current time taken (time of day, time of year), the quality of the obtained image information database of meteorological elements 7 to determine the state of the atmosphere (lighting etc) on the direction of the lens means of obtaining the image that provides the necessary amendments on the quality of the filming. Thus, considering the time of image acquisition, the quality of the received image and positioning data on the basis of data 7 base meteorological elements (ambient temperature, atmospheric pressure, humidity, speed and direction of wind, precipitation, etc. are taken into account the current weather and climate is practical shooting conditions. In addition to the meteorological data corresponding to a particular point on the earth's surface, can be considered data on urban climate or microclimate indoor. It is obvious that taking into account the conditions under which it was acquired image, provides the necessary correction algorithm for the identification of objects and prevent serious errors in addition acquired images of artificial elements.

Based on the data obtained above by means of spatial positioning and state of the atmosphere, obtained by shooting the image of the map with objective information 8 about the environment. As information 8 about the environment using a three-dimensional model of the environment, electronic maps or plans of buildings and structures. For shooting in an urban environment using images of the urban landscape, the location information of objects of city infrastructure, including information on signs, labels, signs, and road signs. For shooting indoors image of the interior, information about finish, setting, and location of equipment. To store the above information is used by the knowledge base 9, dynamically updated in the process of filming and at the same time used as a resource for a variety of info the information, required for image recognition of objects in the environment and their identification.

The environment, which is part of the received image, identified on the basis of the above information. To identify objects in the environment using highly trainable artificial neural network 10, related to the above dynamically updated in the filming process and identify the knowledge base 9. Sharing learning artificial neural network 10 and dynamically updated knowledge base 9, the accumulation and use of information collected in the earlier surveys, provides almost full account of environmental changes, such as changes in the urban landscape that will prevent incorrect identification of objects in the environment due to the use of uncommitted e-cards, interference when shooting, overlapping objects when shooting, etc. adding to the knowledge base 9 information coming from a variety of custom tools 1 image acquisition environment, will provide virtually error-free identification of environmental objects. As a result, the image of the environment complementary to at least one visually perceptible artificial element (for example, information about the quality is the firmness of the roadway; various information about buildings and structures), reflecting the results of identification of environmental objects.
