Technical solution of the present invention is described in detail with specifically embodiment below.These specific implementations below
Example can be combined with each other, and the same or similar concept or process may be repeated no more in some embodiments.
In existing AR processing method, generally comprise there are many AR processing method to realize different calculating demands.Example
Such as vision positioning (Visual Positioning System, abbreviation VPS) method, concurrently build figure and positioning (simultaneous
Localization and mapping, referred to as: SLAM) method, two dimension 2D tracking, three-dimensional 3D tracking etc..In reality
In the product of border, each AR processing method is integrated usually in the same application program with individual AR Implement of Function Module
A variety of AR functional modules are run with and provide different AR functions independently of each other between each AR functional module.For example, an AR is answered
With including SLAM module, 2D tracking module and 3D tracking module in program, if it is desired to the plan view in mobile phone shooting environmental
Case tracking, then only call 2D tracking module.If not only to track to the plane pattern in mobile phone shooting environmental, hand is also positioned
Position of the machine in shooting environmental then needs to call SLAM module and 2D tracking module the two modules simultaneously.As it can be seen that existing
It is inner that multiple independent algorithms (such as SLAM, 2D tracking, 3D tracking etc.) are potted directly into an application by AR product, then basis
Different application demand tune plays different algorithms.Since various AR algorithms usually have respectively different realization principle and method, than
Such as SLAM algorithm has ORB-SLAM, LSD-SLAM, and 3D track algorithm has PWP3D and some tracing algorithms etc. based on edge.
These algorithm realization principles and method difference are very big, can only be as independent algoritic module one by one.
However, since each AR functional module is integrally called as independent algorithm, since module encapsulates and calculates
The reasons such as method principle difference, two independent modules can not share some bottom datas inside algorithm, cause to carry out repeating meter
Calculation leads to the problem of redundant data.Such as not only the plane pattern in mobile phone shooting environmental is being tracked, also want locating cellphone
