Embodiment one
As shown in figure 3, present embodiments providing a kind of star orbital Forecasting Methodology, mobile terminal is applied to, can be included：
Step 301, gathers the geographical location information of current geographic position；
Step 302, shoots the starry sky picture under current geographic position；
Step 303, according to the starry sky picture and the geographical location information, generates the star orbital figure of current geographic position
Picture.
In the present embodiment, by mobile terminal gathering geographic position information and starry sky picture is shot, recycle geographical position
Information and starry sky picture generate the star orbital image of current geographic position, can predict current shooting condition by mobile terminal
Star orbital image under (including acquisition parameters, spot for photography etc.), is easy to star orbital picture of the user to formation under the conditions of current shooting
Anticipation is carried out, and on the one hand user's adjustment shooting condition can be on the other hand alternatively arranged as (as clapped as the reference of star orbital picture pattern
Take the photograph place, acquisition parameters etc.) supplementary meanss, be easy to user to find suitable spot for photography and acquisition parameters, to take ideal
Star orbital picture.
In some implementations, the process for generating the star orbital image of current geographic position in step 303 can pass through such as
Under type is realized：The visible fixed star of identification current geographic position and its distributing position from the starry sky picture；According to described
Reason positional information, determines angle of the star orbital central axis relative to current geographic position；According to star orbital central axis relative to work as
The visible fixed star of the angle in front geographical position, current geographic position and its distributing position, form the star orbital figure of current geographic position
Picture.
In practical application, fixed star and its distribution position can be identified from the starry sky picture by image analysis algorithm
Put.For example, it is possible to passing through object recognition algorithm identifies fixed star from the starry sky picture, and then obtained by image procossing again
The distributing position of each fixed star.Wherein, object recognition algorithm can specifically adopt the object recognition algorithm for being applied to image procossing.
Wherein, in step 301 described collection current geographic position geographical location information, can include：By the whole world
Position system GPS gathers the latitude and longitude information of current geographic position；Current shooting is gathered by gyroscope and looks up angle information.
Thus, during the star orbital image of above-mentioned generation current geographic position, can be according to the latitude and longitude information and upward view angle
Degree information determines angle of the star orbital central axis relative to current geographic position.
In practical application, can according to the longitude and latitude of current geographic position and shoot look up angle, determine arctic astrology
For the angle of current geographic position, center of the Polaris relative to angle as each fixed star motion track of current geographic position
Angle of the axis relative to current geographic position.
In actual movement, when Polaris is zero relative to the angle of current geographic position, that is, during just to Polaris
Star orbital image is concentric circular, the corresponding circle of fixed star, the center of circle of concentric circular is on the axis of Polaris place, radius and each
Distance dependent of the fixed star with respect to the earth.Spot for photography is different, that is to say, that current geographic position is different, then the star orbital for photographing
Image is probably a part for the concentric circular.In practical application, the process for forming star orbital image can include：First determine current position
The visible fixed star in reason position and its distributing position, then determine just present star during Polaris and its distributing position are being formed same
The heart is justified, and finally the central axis further according to each fixed star motion track intercepts the concentric circular relative to the angle of current geographic position
In a part, you can obtain the star orbital image of current geographic position.This form mode is merely illustrative, in practical application, also may be used
To be preset in the CPU of mobile terminal by writing the computing formula of celestial operating rule and its correlation as computer program, by
CPU directly according to the visible fixed star of current geographic position and its distributing position, the longitude and latitude of current geographic position and looks up angle
The star orbital radius is calculated, then draws out the star orbital image.In this regard, not being restricted herein.

Step 404, it is possible to use circumference and earth rotation or other astronomical star motions trajectory calculation formula, in conjunction with collection
Information and the visible fixed star of current geographic position and its distributing position such as the geographical position being presently in and shooting attitude, obtain
To the axial centerline of fixed star motion track, the movement locus of fixed star are calculated, and by image rendering engine in preview interface
On draw out star orbital image.
Specifically, using circumference and earth rotation or other astronomical star motions trajectory calculation formula, in conjunction with the phase in 3 steps
Pass information has obtained center of circle information, substantially calculates the motion track of star, and by image rendering engine in preview interface
Draw out.
Star orbital image formed principle be：Earth rotation brings fixed star relative movement, and the fixed star relative movement is in picture
On reflection be star orbital image.In the present embodiment, the home position of each fixed star in preview graph is corresponding to Polaris
Position, because star motions is substantially with Polaris as the center of circle, determines the home position of each fixed star equivalent in preview graph
Find the relative position of Polaris.Wherein it is possible to according to the position of Polaris place axis and the actual range of fixed star in preview
Reflection on figure is star orbital radius, finally can carry out circumference drafting according to the center of circle and star orbital radius, you can obtain star orbital figure
Picture.
