The technology at the bigger displaying interface of information content, has reached the reinforcement to real-world information.Augmented reality can be script existing
The mankind can be difficult within the scope of sensing capability to experience in the real world real information (such as vision, sound, taste, the letter such as tactile
Breath), by science and technology such as computers, it is added in the information of taken subjective real world after analog simulation, it will be true
Environmental information and virtual object information are added in real time in same picture or space, then make these by certain display means
Information is shown, and human body is enabled to perceive and discover, to reach the sensory experience of the augmented reality of exceeding reality.
With the fast development of computer technology, growth momentum is powerful in recent years for augmented reality.Augmented reality skill
Art demonstrates the brilliance in multiple fields, and starts to be applied to intelligent mobile phone terminal, gradually provides augmented reality branch in various fields
It holds, brings agile user experience, it is more practical also more humane.It is based on augmented reality skill that augmented reality, which is applied to Android,
The explosion type of high speed development and Android device that art is come in is universal.Based on computer augmented reality, integrates reality and find a view figure
The information superposition of virtual scene and reality scene expands systematic difference by piece, Android system, intelligent terminal platform
With reinforcement, also make that system information is more intuitive, efficient reception and registration.From the point of view of the development trend of message area instantly, with people couple
The intensification for being applied to understand of augmented reality, the augmented reality system based on Android intelligent terminal can more be sent out
Exhibition.The augmented reality system accuracy of existing Android platform is low, resolution ratio is low, real-time is poor, stability is poor.
Summary of the invention
Low, resolution ratio that the technical problem to be solved by the present invention is to the augmented reality system accuracies of existing Android platform
It is low, real-time is poor, stability is poor, and it is an object of the present invention to provide using three-dimensional scenic computer graphics principle augmented reality equipment,
Improve precision, resolution ratio, real-time and the stability of augmented reality system.
The present invention is achieved through the following technical solutions:
Using the augmented reality equipment of three-dimensional scenic computer graphics principle, including video acquisition module, Tracing Registration
Module, virtual scene rendering module, basic algorithm module, human-computer interaction interface module and central control module, the video are adopted

The viewpoint change receives world coordinates and is viewing coordinates by world coordinate transformation, and the projective transformation module is by viewing coordinates
Normalized coordinates are transformed to, normalized coordinates are changed into device coordinate and are again transmitted to device coordinate by the display transformation module
Central control module.
Video acquisition module: initialization camera carries out video flowing acquisition and storage to real scene, by the image of acquisition
Data are used for subsequent analysis and processing.
Tracing Registration module: by acquisition image processing analyze, obtain scene in indicate object image position and
Orientation information realizes the Tracing Registration to marker, provides support for the correct rendering load of virtual scene.
Virtual scene rendering module: after Marker Identity, the 3D model of virtual scene is rendered by OpenGL ES, by it
Real-time Overlapping display realizes augmented reality function on marker.
Viewpoint change is equivalent to the locality of adjustment camera, and model converts the position and orientation of then designated model, such as
The combination of these operations is rotated, is translated, scaled or executed to model.Projective transformation is then equivalent to selection camera mirror
Projective transformation can be considered as the specified visual field or what comes into a driver's body by head, that is, determines which object in the visual field and these objects are regarding
Size in open country.Projective transformation and viewpoint change determine how scene will be mapped on computer screen together, projective transformation system
Surely the mode mapped, and which type of screen area is screen display transformation given scenario will be mapped to that in.
Basic algorithm module: package image handles basic algorithm, provides the interfaces such as floating point vector calculating, matrix operation, real
The rudimentary algorithm of existing image real time transfer and Tracing Registration.
Human-computer interaction interface module: designing friendly human-computer interaction interface, hold and embody Human Machine Interface it is understandable,
Simply, practical basic principle.User is guided to select and call as needed corresponding system function by human-computer interaction interface.
Further, Tracing Registration module includes corner characteristics tracing module, point feature tracing module, linear feature tracking mould
Block and curvilinear characteristic tracing module.
Further, video acquisition module includes camera, central processing unit, LCD, JTAG, SDRAM, FLASH, ether
Net controller, remote pc client, the camera are connect with central processing unit, and the LCD is connect with central processing unit, described
