Brief description
Fig. 1 is a kind of flow chart of the automatic generation method of pathology animation provided in an embodiment of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is all other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Fig. 1 is a kind of flow chart of the automatic generation method of pathology animation provided in an embodiment of the present invention, methods described bag
Include following steps S101～S103：
S101：Obtain the first grid chart of normal condition and the second grid chart of pathological condition；
It will be appreciated that described grid chart is to couple together to form netted curved surface by adjacent data point line segment, its
It can be triangle gridding figure.
S102：Determine the grid that there is displacement in described first grid chart according to described first grid chart and the second grid chart
Summit；
It will be appreciated that for determining the grid vertex that there is displacement in described first grid chart, can first determine described first
The corresponding relation of each grid vertex in grid chart and the second grid chart, more described first grid chart is determined based on described corresponding relation
The middle grid vertex that there is displacement.
In determining described first grid chart and the second grid chart during the corresponding relation of each grid vertex, the first net can be contrasted
Trrellis diagram and the second grid chart, determine same vertices and different summits, then travel through all same vertices, find all adjacent not
Same summit, is then numbered to adjacent different top point according to this group summit, then the adjacent vertex to numbered summit
It is numbered, successively the complete all summits of searching loop, so that it is determined that going out the corresponding relation of each grid vertex.
Then, there will be the first grid vertex of corresponding relation and the second grid vertex carries out location comparison, in position not
Meanwhile, this first grid vertex existed as in described first grid chart the grid vertex of displacement.
S103：Pathology animation is generated based on the described grid vertex that there is displacement and default animation duration.
In implementing, when the function generating animation frame is called, obtains current time and rise with described pathology animation
Time difference between beginning frame, based on the grid vertex, time difference and the described default animation that there is displacement in described first grid chart
Duration generates animation frame, and to generate pathology animation, detailed process is：：
Travel through the grid vertex that there is displacement in described first grid chart, and using the grid vertex traversing as target network
Lattice summit；
Obtain the displacement on described target gridding summit；
Determine the present bit on described target gridding summit according to described displacement, time difference and described default animation duration
Put；
For example：Displacement is 100 pixels, a length of 10s during default animation, and the time difference is 0.3s, now, you can calculate
0.3/10*100=3, that is, for target gridding summit, it is from the corresponding initial position of the first grid chart to the second grid chart
Corresponding final position moves 3 pixels, so that it is determined that the current location on target gridding summit.
Current location according to described target gridding summit adjusts corresponding grid vertex in described first grid chart, until
After traversal terminates, using the first grid chart after adjustment as the animation frame generating.
It will be appreciated that it is poor due to there may be color range between the first grid chart and the second grid chart, therefore, in step
In S101, also can obtain described first grid chart and the color range of the second grid chart is poor.
Correspondingly, in step s 103, can grid vertex that is poor based on described color range, there is displacement and default animation duration
Generate pathology animation.
Detailed process is essentially identical with said process, and difference is：Also need to determine the color range of pathology animation, example
As：A length of 10s during default animation, the time difference is 0.3s, and color range difference is 20, now, you can calculate 0.3/10*20=0.6, this
When, it can be adjusted 0.6 color range from the corresponding initial color range of the first grid chart to the second grid chart corresponding terminal color range.
The present embodiment passes through to obtain the first grid chart of normal condition and the second grid chart of pathological condition, according to described the
One grid chart and the second grid chart determine the grid vertex that there is displacement in described first grid chart, there is displacement based on described
Grid vertex and default animation duration generate pathology animation, thus pathology animation need not be made using by technical staff, save people
Power and time.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
