Specifically, after the first adjustment information is obtained, a first distortion parameter corresponding to the first adjustment information may be selected from a plurality of distortion parameters calibrated in advance according to a correspondence between the first adjustment information and the plurality of distortion parameters. Further, a user specific distortion parameter is determined based on the first distortion parameter.
In this embodiment, the plurality of distortion parameters respectively correspond to different position coordinates in the preset space; the preset space is a space where human eyes are located after a user wears the electronic equipment.
In one embodiment of the disclosure, the determining, according to the first distortion parameter, a specific distortion parameter of the user may include: generating a second picture according to the first distortion parameters and controlling to display the second picture; receiving a second control instruction input by the user according to the distortion concave-convex property of the second picture; and if the second control instruction indicates that the second picture distortion correction is successful, determining the first distortion parameter as the exclusive distortion parameter of the user. And if the second control instruction indicates second adjustment information corresponding to the second picture, selecting a second distortion parameter corresponding to the second adjustment information from a plurality of pre-calibrated distortion parameters according to the second adjustment information, and determining the exclusive distortion parameter of the user according to the second distortion parameter.
Specifically, after the first distortion parameter is selected based on the adjustment information generated by the distortion convexity of the first picture, distortion correction processing can be performed on the original picture corresponding to the first picture based on the first distortion parameter, so as to obtain a second picture, a user can watch the distortion convexity of the second picture, a second control instruction input by the user is received, if the second control instruction is the adjustment information, the distortion correction is continued until a control instruction input by the user and indicating that the distortion correction is successful is received, and the distortion correction is ended.

Thereby improving the adaptability of the equipment and meeting the personalized requirements of users.
Referring to fig. 3, fig. 3 is a second flowchart of a distortion correction method according to an embodiment of the disclosure. In the embodiment, the influence of eye rotation of human eyes on distortion parameters is considered, the distortion parameters of pictures with small view angles and pictures with large view angles are respectively determined, and the two distortion parameters are fused to obtain the exclusive distortion parameters of a user. Specifically, the distortion correction method includes:
301. The method comprises the steps of calibrating distortion parameters corresponding to a plurality of positions in a preset space in advance, selecting an initial position from the positions, and generating a first picture based on the distortion parameters corresponding to the initial position.
Specifically, different people wear the same VR device because of different facial shapes and wearing habits, and the coordinate positions of eyeballs under the world coordinate system of the VR device are different. The range of the preset space may be a stereoscopic range determined by sampling eyeball positions of a plurality of users.
In the embodiment of the disclosure, in order to improve the progress of distortion correction and reduce the operation of a user, when a picture is presented to the user for the first time, a picture obtained after correcting an original picture by using a distortion parameter corresponding to a certain position in a preset space may be selected. For example, a position with a higher probability may be selected as the initial position.
302. And controlling to display the first picture. The angle of view of the first picture is less than a first preset value, which is related to the range of angle of view of the human eye when the human eye is looking straight.
Specifically, since the user foreground view (the eyeball of the user can observe the view edge without rotation) is a scene which is more used by the user, the determination of the distortion parameters under the foreground view can be performed by displaying the first picture with the view angle smaller than the first preset value. When the angle of view is less than a first preset value, the user can view the edge of the picture without rotating the eyeball.
For example, as shown in fig. 4, the display 101 displays a first screen 1011, and the angle of view of the first screen 1011 is smaller than a first preset value, so that the user can view the edge of the screen without turning the eyeball. In this case, the display screen 101 displays a prompt message "please observe the distortion convexity of the picture, push the rocker to adjust until the picture is undistorted, and then please pull the trigger to enter the next adjustment" so as to enable the user to operate according to the prompt.
303. A first control instruction input by a user according to the distortion unevenness of the first screen is received.
304. Whether the first control command indicates that the first frame correction is successful is determined, if not, step 305 is executed, and if yes, step 306 is executed.
305. According to first adjustment information indicated by a first control instruction, selecting a first distortion parameter corresponding to the first adjustment information from a plurality of distortion parameters calibrated in advance, and generating a second picture according to the first distortion parameter. The second frame is returned to the step 302 as the new first frame.
306. And controlling to display a third picture. The angle of view of the third frame is greater than a second preset value that is related to whether the edge of the frame that is viewed by the human eye needs to be rotated.
Specifically, after the distortion parameters of the small view angle scene are adjusted, the picture of the large view angle scene can be displayed through the display screen, and when the view angle is larger than a second preset value, the user needs to rotate eyeballs to see the edge of the picture.
For example, as shown in fig. 4, after the first screen 1011 is adjusted, the display 101 displays a third screen 1012, and the angle of view of the third screen 1012 is greater than the second preset value, so that the user needs to rotate the eyeball to view the edge of the screen. In this case, the display screen 101 displays a prompt message "please observe the distortion convexity of the left and right edges of the screen, push the rocker to adjust until the edges of the screen are undistorted, and then please trigger to complete adjustment", so that the user can operate according to the prompt and complete distortion correction.
307. And receiving a third control instruction input by a user according to the distortion concave-convex property of the edge of the third picture.
308. Whether the third control command indicates that the third frame correction is successful is determined, if not, step 309 is executed, and if yes, step 310 is executed.
309. And determining the exclusive distortion parameter of the user according to third regulation information indicated by a third control instruction and the second distortion parameter corresponding to the current first picture.
310. And determining the exclusive distortion parameter of the user according to the fourth distortion parameter corresponding to the third picture and the second distortion parameter corresponding to the current first picture.
Specifically, if the third control instruction indicates that the third picture is successfully corrected, the fourth distortion parameter corresponding to the third picture and the second distortion parameter corresponding to the current first picture may be fused to generate the dedicated distortion parameter of the user.
In an embodiment of the disclosure, the determining, according to the third adjustment information and the second distortion parameter corresponding to the first picture, the specific distortion parameter of the user may include: according to the third adjusting information, selecting a third distortion parameter corresponding to the third adjusting information from a plurality of distortion parameters calibrated in advance; and carrying out weighted summation on the third distortion parameter and the second distortion parameter corresponding to the first picture to obtain the exclusive distortion parameter of the user.
In one embodiment of the present disclosure, the third distortion parameter and the second distortion parameter each include components corresponding to a plurality of angles of view, respectively; the weighted summation of the third distortion parameter and the second distortion parameter to obtain the exclusive distortion parameter of the user may include: for each angle of view, carrying out weighted summation on the corresponding component in the third distortion parameter and the corresponding component in the second distortion parameter to obtain a target component corresponding to the exclusive distortion parameter; and determining the exclusive distortion parameter according to the target components corresponding to the view angles.
In one embodiment of the present disclosure, the weights of the components in the second distortion parameter decrease with increasing angle of view; the weight of each component in the third distortion parameter is reduced with the angle of view of the third picture as the center, as the angle of view is farther from the center.
Illustratively, as shown in fig. 5, the abscissa is the angle of view before correction, the ordinate is the angle of view after correction, the solid line curve is the third distortion parameter, and the broken line curve is the second distortion parameter. Assuming that the angle of view of the third picture is 0.70, the weight of the dashed curve may be set to decrease from 1 with the angle of view being away from 0.70, centering on 0.70. Assuming that the angle of view of the first picture is 0.55, the weight of the second distortion parameter may be set to 1 at 0 to 0.55, decreasing with increasing angle of view. Based on this, fusion of the two distortion parameters is completed. When the angle of view is close to the first picture, the second distortion parameter of the first picture is mainly used, and when the angle of view is close to the third picture, the third distortion parameter of the third picture is mainly used.
In the process of adjusting the distortion parameters of the edge, a plurality of pictures with different angles of view can be displayed, and the distortion parameters of the edge can be respectively determined, so that a plurality of distortion parameters can be obtained, and the distortion parameters are fused with the second distortion parameters corresponding to the first picture. The weight of each distortion parameter in the fusion process takes the field angle of the corresponding picture as the center, and the weight is reduced from 1 along with the field angle principle center.
311. And storing the exclusive distortion parameter and the account information of the user in a correlated way so as to automatically call the exclusive distortion parameter when the user logs in again.
The account information may be information indicating identity, such as face information, fingerprint information, and a user name, which are stored in advance by the user. By means of the mode of storing the exclusive distortion parameters and the account information in an associated mode, when a user uses the equipment, images suitable for the user can be provided for the user automatically based on the exclusive distortion parameters of the user.
As can be seen from the above description, the distortion correction method provided in this embodiment provides pictures of different angles of view for the user, so that the user can determine distortion parameters of different angles such as forward looking and observing edges, and further obtain the dedicated distortion parameters of the user based on the fusion result of multiple distortion parameters. The accuracy of distortion parameters is greatly improved.
