Description
Technical field
The application is related to field of virtual reality, more particularly to a kind of interactive panoramic video storage method and device.
Background technology
With making constant progress for scientific and technological information, with the continuous lifting of people's living standard, people are for things
Understanding deepens continuously, and without only residing within hearsay and cumbersome word is illustrated and introduced above, but rises to
In the aspect for reducing objective things style.Whether word description is consistent with hearing with actual environment, and we must not for this
And know.But certainly panoramic video can answer this problem, the real actual environment of portrayal.Therefore, aphorama
Frequency will even more the immense value and advantage of its own have been given play in fields in this respect.
Panoramic video is to be altered to link up by countless Zhang Quanjing pictures to constitute smooth clearly dynamic video image.But it is complete
The shooting of scape video is then to tailor the video size of standard according to client's needs, demand and viewing platform.Current panorama
The style of shooting of video is divided into two kinds：One kind is to take photo by plane.This requires that place, scene are open, and area is larger.And another is then
Eyelevel shot on the ground, this shooting can clearly show many details of environment, and let us understands the specific position of environment
Put, concrete shape, details etc..The purposes of two kinds of styles of shooting is different, and the former is intended to the assurance of integral macroscopic, and the latter is then
It is to emphasize part and details.
The storage mode of panoramic video is mainly the video data for first gathering each photographing module and carried out in the prior art
Integrate, unified storage then is carried out to the video after integration in case playing.The storage mode of above-mentioned panoramic video is greatly met
The broadcasting demand of panoramic video, preferably realizes the bandwagon effect of panoramic video, there is very strong immersion sense；But equally exist
Some problems, i.e. because the storage of above-mentioned panoramic video is all often " three-dimensional " storage, and panoramic video often has higher
Resolution ratio, longer time length, therefore, above-mentioned storage mode cause a large amount of occupancy to computer memory space, therefore, have
Wait to propose a kind of efficient video resource storage method, to reduce the occupancy to computer memory space.
The content of the invention
A kind of interactive panoramic video storage method, methods described comprises the following steps：
S1, obtains the collection viewpoint of panoramic video, so as to select the sight angle of the data frame of the panoramic video；
S2, splits according to the sight angle to the panoramic video；
S3, identification code is drawn for the frame of video of the panoramic video through fractionation；Store described through the complete of fractionation according to the identification code
Scape video；
S4, the panoramic video through fractionation is extracted after the panoramic video play instruction is received according to the identification code,
The panoramic video through fractionation is recombinated to play.
