Definitions
- the invention relates to a method for marker-based projection of virtual objects into a predetermined level, in particular for augmented reality applications.
- predefined markers are placed in the natural environment and are recognized by a computer system with a camera by means of image processing or evaluation.
- This computer system with camera can be implemented, for example, by a cell phone with a camera.
- the augmented reality system is able to calculate the position of the marker plane in three-dimensional space relative to the camera position from the projection of the marker into the camera image plane. With the help of this information, virtual 3D objects can then be correctly projected onto the plane in which the marker is located.
- a level is specified by the marker, which is located on a table, for example.
- game figures, game boards, avatars, etc. are used as 3D objects. used.
- World need such as landscape and architectural modeling.
- Other applications are games, in particular special local multiplayer games, such as board games, but also strategy, adventure and fighting games.
- the invention has for its object to solve these problems, especially for a mobile phone.
- the method according to the invention enables fast and intuitive design of complex game content for augmented reality applications.
- the method according to the invention is extremely resource-saving and thus enables real-time augmentation. This is achieved through the use of a single marker and the addition of simple symbols for the robust and fast detection of complex game content.
- the number of symbols to be recognized can be kept small, since these can be given a different meaning depending on the context of the game and these can then be replaced by different 3D objects.
- FIG. 1 shows a marker according to the prior art
- FIG. 2 shows a landscape designed according to the invention with a marker and with symbols.
- a single marker is used in connection with a plurality of symbols.
- the user can use a single marker M to build complex content, for example the design of a game landscape, for augmented reality applications in a very simple manner, without additional markers having to be installed in the environment.
- This marker M determines the level for the projection of the objects. It is, so to speak, an "empty" marker. Any objects can be placed in a plane that is spanned by this one marker M using primitive symbols S or shape elements.
- the symbols S are realized, for example, by round or oval, angular or rectangular shaped elements.
- the symbols can be colored or have colored markings or codes.
- One or more lines L can also be used as symbols.
- the symbols define the objects to be displayed with regard to their type, for example a house.
- the symbols S are preferably chosen such that they can be easily detected using methods of digital image processing, without the need to use complex methods for pattern recognition.
- the means for digital image processing are provided, for example, by a so-called video cell phone.
- the objects corresponding to the symbols can be correctly projected into the real camera image.
- the 3D position of an object is clearly defined by the point of intersection in three-dimensional space between the line of sight of the projected feature and the plane of the marker M.
- Another marker is necessary if, for example, a further perspective representation of objects is desired. This can be the case if some objects are to be displayed on a table and others at a greater distance. According to the invention, a further marker with several symbols is then used for this purpose.
