Description
Technical field
The present invention relates to image processing field, specifically a kind of storage method of 3D rendering, display packing and 3D rendering file format.
Background technology
Pathological section is the one of Pathologic specimen.During making, part is had the process through various chemicals and burying storage of the tissue of pathological changes or internal organs, so as to fixing hardening, microtome is thinly sliced, stick on slide, contaminate with shades of colour, check under microscope different multiplying, to observe pathological change, make pathological diagnosis, offer help for clinical diagnosis and treatment.Pathological section scanning means is that pathological section is changed into digitized a kind of instrument, instead of conventional microscope.
In existing scanning means, in order to be able to allow doctor better simulate microscopical effect, all it is proposed the scanning equipment of 3D scanning imagery one after another.3D scanning carries out the entire scan under different object distances pathological section in same position exactly, and the image of scanning is stored in computer hard disc after being digitized into；To check a certain position in section, it is possible to check the image of different object distances as microscope.But there is the file structure being stored in computer hard disc after the multiple image by above-mentioned scanning is digitized in the prior art, different file structures has different performances.
And the pathological section of a standard (scanning tissue size 1.5cm*1.5cm) uses scanning means after 40X objective scan, whole view data size of single object distance scanning is about 10G, about 600M after being compressed by jpg.Carrying out 3D scanning again, general acquiescence sweeps 10 different object distances, then file raw image data size has reached 100G, about 6G size after compression.Owing to image file is excessive, it is impossible to all of view data is read (existing general computer memory is 8G) in computer memory, directly checks for user.Common practice is, the position that input to be checked, demonstrating corresponding data required for reading from fixed disk file afterwards, thus reaching just can realize checking the function of image without all of view data is read in computer memory, therefore the structural design of file is extremely important.
In the prior art, generally there are two kinds of storage modes:
(1) being stored by multiple files by the image that a section carries out 3D scanning, each object distance has a file.Which results in file many, not manageability.And user is when checking different object distances, need to constantly changing file, cause that program is slack-off, the operation sense of user is poor.
(2) image that a section carries out 3D scanning acquisition is stored with a file, user is when checking different object distances, file is changed without or else disconnected, but in view of amount of image information is too many, and the design of existing storage method is unreasonable, program is still very slow, and then causes that user operation sense is still poor.
This is the deficiencies in the prior art part.
