Description
Technical field
The present invention relates to a kind of panoramic picture jump method, belong to computer vision field.
Background technology
Existing technical scheme is then the thought according to panorama sketch roaming, and final correction chart is imaged according to virtual camera
Thought connected with spherical coordinate, establish contacting between panorama sketch coordinate and screen coordinate.
Existing panoramic picture redirects the thought that scheme is in accordance with panoramic picture roaming, is moved to a certain angle of visual field every time
When, software algorithm needs to update contacting between correction chart and spherical coordinate, and such a mode amount of calculation is huge, is ensureing real-time
On the basis of to system hardware configuration require it is higher.
The content of the invention
In view of the shortcomings of the prior art, technical scheme provides a kind of panoramic picture jump method, and it is used for reference
In game picture design process, thinking that picture redirects on the basis based on OPENGL coordinate transforms, passes through image
Texture coordinate, model vertices coordinate, modelview matrix, projection matrix and normalized, by panorama sketch coordinate and screen
Coordinate connects, when clicking a certain location point on screen, you can connected with panorama sketch coordinate, it is sub corresponding to completion
Image redirects.
Technical scheme includes a kind of panoramic picture jump method, and this method includes：Obtain panorama harvester
The panoramic picture of collection, parsing obtain multiple panoramic picture coordinates；B. OPENGL combination panoramic picture coordinates and panorama sketch are based on
As generation model view projections matrix；C. image is calculated according to the model view projections matrix and OPENGL viewing matrix
Screen coordinate corresponding to coordinate；D. the matching of the screen coordinate and panoramic picture coordinate is performed, son is completed according to matching result
Image redirects.
According to a kind of described panoramic picture jump method, wherein step A also include：S21, panoramic picture is solved
Analysis, multiple labels are set in panoramic picture, a panoramic picture coordinate, and then coordinate text corresponding to generation are corresponded at each label
Part, and panoramic image file and coordinate file are sent into OPENGL and perform processing；S22, is corrected and more according to panoramic picture
The new viewing angle of visual field, and show image after correction.
According to a kind of described panoramic picture jump method, wherein step B also includes：Detect that viewing visual angle field becomes
During change, corresponding MVP matrixes in OPENGL are updated.
According to a kind of described panoramic picture jump method, wherein step C also includes：Detect whether to click screen in real time
Action, if only the adjustment viewing angle of visual field, and return to step B if detecting the presence of the action for clicking screen, are looked into without if
Multiple panoramic picture coordinates corresponding at screen taps are looked for, and are matched with the screen coordinate.
According to a kind of described panoramic picture jump method, wherein step C also includes：The return to step B if it fails to match
And adjust the viewing angle of visual field.
According to a kind of described panoramic picture jump method, wherein step D also includes：According to the screen coordinate matched,
Subgraph redirects corresponding to panorama sketch coordinate corresponding to lookup and completion.
Beneficial effects of the present invention are：Reduce the hardware cost of image jump system.
Brief description of the drawings
Fig. 1 show the overview flow chart according to embodiment of the present invention；
Fig. 2 show the detail flowchart according to embodiment of the present invention.
Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.The panoramic picture jump method of the present invention is applied to image jump system.
Fig. 1 show the overview flow chart according to embodiment of the present invention.It is as described below, including：A. panorama is obtained to adopt
The panoramic picture of acquisition means collection, parsing obtain multiple panoramic picture coordinates；B. based on OPENGL combination panoramic picture coordinates and
Panoramic picture generation model view projections matrix；C. calculated according to the model view projections matrix and OPENGL viewing matrix
To screen coordinate corresponding to image coordinate；D. the matching of the screen coordinate and panoramic picture coordinate is performed, according to matching result
Complete redirecting for subgraph.
Fig. 2 show the detail flowchart according to embodiment of the present invention.Its flow is as follows：

File is read into software program.
(2) according to image after the display correction of the currently viewing angle of visual field.
(3) according to model view projections matrix corresponding to currently viewing angle of visual field generation OPENGL.
(4) the model view projections matrix in OPENGL viewing matrix and (3), calculating panorama sketch coordinate pair should
Screen coordinate.
(5) determine whether to click the action of screen, the then adjustment viewing angle of visual field that it's not true, turn to step (2).
(6) coordinate for clicking screen location is obtained, the coordinate is matched with the coordinate in step (4), if matching
Failure, then the adjustment viewing angle of visual field, turns to step (2).
(7) according to the screen coordinate matched, panorama sketch coordinate corresponding to lookup, you can the jump of subgraph corresponding to completion
Turn.
It is described above, simply presently preferred embodiments of the present invention, the invention is not limited in above-mentioned embodiment, as long as
It reaches the technique effect of the present invention with identical means, should all belong to protection scope of the present invention.In the protection model of the present invention
