Vegetarian refreshments, and the ratio of width to height of the picture to be selected is more than or equal to 2:1, and the ratio of width to height of the picture to be selected is less than 4:1, then
It is judged as that the picture to be selected is 360 degree of panoramic pictures.
360 degree of panoramic pictures described in the present invention are referred to：The 360 degree of panoramic pictures shot with wide angle camera, not typically
" panoramic pictures " that mobile phone shoots, because the camera shooting angle of general mobile phone is very little, it is impossible to which reaching the 3D scenes of VR needs
The picture standard wanted.
The application scenarios of the present invention are below described.
The present invention is a kind of method for selecting under VR patterns from android mobile phones and filtering out 360 degree of panoramic pictures, mainly
It is applied to the function of browse of 360 degree of panoramic pictures of VR equipment and mobile phone.
In the present invention, the wide high proportion of picture itself is calculated, the ratio of width to height and size within the specific limits, are then entered
Row selects to filter.If within certain proportion, and size is within limits, it is believed that it is 360 degree of panoramas
Picture, in being indicated in the 3D scenes of VR.
First, 360 degree of panoramic pictures are the captured photos that rotates a circle using wide angle camera, along horizontal direction, institute
So that 360 degree of panoramic pictures of standard can be to be fitted in completely on a super large spheroid, and if we stand in spheroid
The heart just looks like the visual angle for having returned to photographer originally, there is a kind of sensation on the spot in person.So, the width of 360 degree of panoramic pictures is high
Than being 2：1, just as the world map of an expansion, by the correction of algorithm, can be fitted in completely on tellurion.
It is exactly 16 that the ratio of the 2d pictures that we shoot at ordinary times is modal:9 and 4:3, they are respectively less than 2:1.So right
For 360 degree of panoramic pictures, 2:1 is a very important parameter.
The picture that pans can typically use bugeye lens (180 degree, similar to the eyes of fish), the camera lens in such as Fig. 3
406.If the camera lens for using is not the camera lens of 180 degree, but during such as 90 degree of camera lens 405, photographer horizontally rotates one week and claps
After taking the photograph, the image of camera surface and underface also cannot be just photographed, less shooting angle will lose more pictures,
But the picture of this partial loss can cause the height of the picture of last shooting not reach the half of width.That is, using 180
The lens shooting of degree to distant view photograph be exactly pixel be 4000x2000.And 90 degree of lens shootings are adopted, due to upper and lower certain limit
Interior picture loss, the picture for finally obtaining is 4000x1000 pixels, and its ratio of width to height is 4:1.Thus the ratio of panoramic pictures
Example should be more than or equal to 2:1.
Below description determines that disappearance is how many relatively reasonable on picture height.By real experiences, find when picture ratio is
4000x1000 pixels, i.e., (4:1) when, that is, the picture of more than half is have lost on the height of picture, is browsed in vr
During this picture, it is very serious that picture will deform, and this picture is browsed in VR scenes and also just lose original meaning.And
And, be also not in such picture, so by 4 in normal photographing or when making 360 degree of panoramic pictures:1 is set as
The maximum of ratio.
It is at present most common to the size of 360 degree of panoramic pictures be 4000x2000 pixels, and 1000x500 pixels it
Under experience effect it is just poor, pixel is too low, and picture compare and obscures, and user has been experienced less than virtual reality
Feel.So, the dimension of picture of 1000*500 is set as to select the threshold value of the filter condition of 360 degree of panoramic pictures sizes.
According to more than the characteristics of the ratio and size of analysis panoramic pictures, 360 degree of panoramic pictures are assert, obtain first
The width of picture is high, and panoramic pictures need three primary conditions, 1, width be more than 1000 pixels.2nd, the ratio of width to height is more than or equal to 2:
1.3rd, the ratio of width to height is less than 4:1.
The characteristics of Fig. 4 is with going up 360 degree of panoramic pictures according to this, obtains the flow chart of 360 degree of panoramic pictures of a selection.Bag
Include following steps：
Step 501, reads picture；
Step 502, the width for obtaining picture is high；
Whether step 503, judge width more than 1000；
Whether step 504, the ratio of width to height for calculating picture is more than or equal to 2:1；
Whether step 505, the ratio for calculating picture is less than 4:1.
When picture meets step 503,504,505 condition simultaneously, it is 360 degree of panoramic pictures to be considered as it.
The present invention can quickly identify all 360 degree of panoramic pictures included in equipment, and user need not be by picture
In being put into fixed catalogue, meanwhile, user can be placed on the panoramic pictures of oneself in different catalogues, in VR patterns to user
The file for placing picture is classified, and what user can be faster finds the picture for oneself wanting to check, while will not show
Show 2D pictures.
Present invention may apply to the treating method that mobile phone and VR equipment are classified to panoramic pictures, is also applied for VR
Integrated machine equipment.
Presently preferred embodiments of the present invention is the foregoing is only, protection scope of the present invention is not intended to limit.It is all
Any modification, equivalent substitution and improvements made within the spirit and principles in the present invention etc., are all contained in protection scope of the present invention
It is interior.
