Description

APPLICATION FOR IDENTIFYING, GEO-LOCATING AND MANAGING POINTS OF INTEREST (POI)
The present invention refers to an application for updating, improving and organising geographic information coupled with technical-commercial information.
Namely, the geographic information are Points Of Interest, called POI, identified in geo- coordinates, latitude and longitude; technical- commercial information describe the company characteristics of individual users enrolled in a network: web sites, connections among different sites, contact-managing system, search engines, etc.
The process of searching and selecting a place involves both "what" and "where". Often this process requires a search for many sources of information with a great waste of time and not always with satisfactory results.
Among the most common tools used for locating and qualifying a Point Of Interest (POI), the following are mentioned: telephone directories, White Pages and Yellow Pages, Internet and the search on digital maps, satellite navigators, maps available on PC, hand-held devices on board a vehicle, communication systems and devices: he phone used for performing a call for receiving information about a road path to be followed, etc. The communication can be wireless and does not need to be of the voice-type.
The prior art related to managing qualitative POI integrated in a program for mapping and simultaneously evaluating "what" and "where", on many POI, is provided by document No. US20050251331A1. This document describes: managing information that need frequent updates by organising customised POI; creating a folder in which groups of POI are selected and synchronised with respect to a centralised database; displaying POI on a mapping program, with the chance of managing POI by means of the user through individual marking systems; simultaneously displaying POI and one or more categories of qualitative information associated therewith; creating a hierarchical list of POI, depending on different commercial categories; capability of selecting a category among a plurality of configurations, displaying only a category level of interest; dividing into planes or layers in which Points Of Interest and updates information are placed and stored; assigning symbols linked to further Points Of Interest, and storing the symbols .
Patent US20050251331A1 further discloses the management of objects - a building, a road, etc. - present in the geographic map, using a series of symbols or icons having a different graphics, giving instructions about how to move the marker with respect to object parts in order to define the POI with respect to a more representative point of the object; for such purpose, an aerial photograph can provide further references; for example, it can contain a photograph of the building or the road in cui the user places the marker or, through drawing tools, identifies such building part, the elevation plane or a well-defined point in a road.
A limit given by the above mentioned prior art is the arbitrary identification of a user regarding parts of objects related to POI through different symbols or even through graphic drawing, outlining a schematic element in an aerial photograph. Often the object, with respect to which the user wants to define a POI, is displayed only from a shooting of the satellite type; which makes still more difficult to locate parts of the object like: entrance, building floor, a point in a road. Marking the entrance of a building or a shop, of a building floor, etc. thereby results inaccurate; the user must then draw the shape of building, entrance, building floor, etc. through a graphic drawing program, with the risk of losing the presentation clarity of the object part associated with the POI.
Object of the present invention is solving the above prior art problem by providing a method for identifying one or more Points Of Interest (POI) , removing the operation of drawing the outline of objects present in an aerial photograph, using markers to point out objects present in two- dimensional photographs extrapolated from three- dimensional maps of the immersion type.
This object is obtained by connecting a system for geo-locating and managing points of interest (POI) to software for managing panoramic maps, in order to reach an excellent visibility in the net, both at local and at global territorial levels.
A further object of the invention is increasing the amount of information that can be extrapolated from different types of panoramic maps and able to be associated with the Points Of Interest (POI) .
The above and other objects and advantages of the invention, as will appear from the following description, are obtained with an application as described in claim 1. Preferred embodiments and non-trivial variations of the present invention are the subject matter of the dependent claims.
The present invention will be better described by some preferred embodiments thereof, provided as a non-limiting example, with reference to the enclosed drawings, in which:
FIG. 1 shows a three-dimensional environment in spherical coordinates from which an immersion map is extracted, used for pointing out the Points Of Interest POI;
FIG. 2 shows the part of a panoramic image belonging to the immersion map used for pointing out the POI;
FIG. 3 shows the video screen containing an aerial photograph obtained from a geo-stationary map and the part of an immersion map used for pointing out the POI; FIG. 4 shows a marker, called hotspot, suitable to exactly identifying the object part connected to the POI .
In the following description, the terms "geographic coordinates", "geo-coordinates" , and "geo-codes" are used interchangeably and substantially refer to any approach for coding a geographic place in a data representation that can be manipulated by a computer, since they are, for example, a pair with a latitude value and a longitude value.
The present is an application for punctually identifying one or several Points Of Interest (POI) , by correlating the geographic coordinates, with images or sequences of panoramic images (7), said images (7) belonging to an immersion map coming from a rendering in a three-dimensional environment with spherical coordinates (6) . The rendering of an object is given by the two- dimensional or three-dimensional image (7), on which it is possible to: place dynamic hotspots (2) directly in fixed video points, namely accurate points of parts shown in the image (7); display three-dimensional elements (3) present in the image (7) ; decorate the video with special three- dimensional effects, such as fog effect or particles effect, LensFlare; process the photograms with video effect like de-saturation, blur, contrast; interact with other external programs such as satellite maps or GPS navigators, two- and three-dimensional geographic maps, videogames.
Said hotspots (2) are active markers that allow accessing related texts, Internet windows, or other media such as video, photograph, etc.
In addition to the Point Of Interest (POI) that is related to an exact point in the image (7), the hotspot marker (2) identifies, in particular in a 360° photograph obtained from the image (7) belonging to the immersion map, exactly the part
(3) of the object connected to the Point Of Interest (POI) : the entrance of a building, the elevation floor of the building, a window, etc.
In particular, the immersion map can be of the type dealing not only with the building surface where one lives, but can involve the whole internal or external volume of a room, a palace or another building designated through a Point Of Interest
(POI) . In fact, the three-dimensional mapping of the internal volume of a building is performed through a special support of an optical apparatus, of the type capable of reaching different heights, allowing the 360° mapping for every reached height.
The application for identifying the Points Of Interest (POI) can then appear inside a portal that displays a two-dimensional map (5) and the immersion map, or can be displayed individually as real Internet site, equipped with a page called "where we are" or a similar name, and with a two- dimensional map (5) with plane 360° photograph that accurately identifies the Point or Points Of Interest (POI) chosen by the single user.
Specifically, the application is a real web site that can be made by assembling many pages very easily. The internal pages composing the application can be modified with the frequency desired by the user by using simple tools, actual software applications designated for the direct online publication (without installing them on a PC) , that therefore are able to add and modify in real time information of all types (texts, videos, photographs, panoramic photographs, catalogues...) related to company activities.
In particular, the user is able to display his own Points Of Interest (POI) placed inside the image (7) by exploiting a punctual geo-referring system, namely at a level for identifying the part (3) of the object (entrance, floor, etc.) through hotspots (3) , with the advantage of increasing the computation accuracy level of paths down to the level of street number of the seats of inserted subjects .
The application for displaying Points Of Interest (POI) through hotspots (2) of the present invention has a series of advantages: flexibility and absolute autonomy in managing web pages conferred to the user that, by using user-friendly resources, can directly take care of updating the promotional and information contents; easy identification of the Points Of Interest (POI) through marking with hotspots (2) of the objects or parts (3) displayed in the image (7) of an immersion map or in the 360° photograph;
- removal of the arbitrary intervention for identifying the Points Of Interest (POI) performed according to the prior art through graphic drawing programs;
- reduction of costs of web marketing tools due to the fact that the company must not consult specialised firms for creating its own Internet pages and is not compelled to design and search technologic solutions to be able to make its own web pages;
- absolute accuracy in placing the Points Of Interest (POI) geo-referenced in the immersion map.
