Fig. 1 is a schematic flow chart of a method for adjusting a curved screen display position in an embodiment of the present application, and as shown in fig. 1, the method for adjusting a curved screen display position may include the following steps:
step S101, obtaining a current image through a camera, and determining a depth distance and a relative angle between a human face and the camera according to the current image.
In this embodiment, the execution main body may be an intelligent sound box with a camera and a curved screen, as shown in fig. 2, there may be one camera or two or more cameras, which is determined according to the design form of the intelligent sound box with the curved screen. The current image, namely the image containing the face, is obtained through the camera, and the depth distance and the relative angle between the face and the camera can be determined according to the current image. Wherein, the depth distance is the depth from the human face to the camera; the relative angle is an angle from the face to the camera with respect to the central axis of the camera, as shown in fig. 3, fig. 3 is a top view between the face and the camera.
It can be understood from fig. 2 that the curved screen displays the image at the same position, and the image is viewed at different viewing angles, which causes different experiences for the user, and the viewing effect at some positions is more reduced, so that the current image is acquired by using the camera, and the depth distance and the relative angle between the face and the camera are determined according to the image, so as to determine the position of the user relative to the curved screen, thereby displaying the image in a manner more suitable for the position of the user.
Optionally, the camera may use a depth camera, and the depth distance and the relative angle between the face and the camera may be determined according to the current image acquired by the depth camera, wherein a face detection algorithm may be used to detect the face in real time, and the change in position of the face is monitored, so that the display area of the curved screen is adjusted in real time.
And S102, determining a screen display area of the curved screen according to the depth distance and the relative angle.
In this embodiment, the position of the user with respect to the curved screen may be confirmed according to the obtained depth distance and relative angle, thereby determining the screen display area of the curved screen. The curved screen can be a flexible curved screen.
Optionally, the screen display area of the curved screen may generally be set to occupy half of the screen of the curved screen, and the screen display area may also be adaptively adjusted according to the aspect ratio of the curved screen and the curvature of the curved screen, which is not limited herein. After the screen display area of the curved screen is determined, other areas of the curved screen which are not displayed can be replaced by black so as to improve the watching experience of a user.
Optionally, as shown in fig. 4, step S102 includes:
step S401, obtaining a corresponding relation between the depth distance and the angle relation model, and selecting the angle relation model corresponding to the depth distance according to the corresponding relation.
And S402, selecting a screen display area corresponding to the relative angle according to the angle relation model.
In this embodiment, a corresponding relationship between the depth distance and the angle relationship model is preset, that is, a corresponding angle relationship model exists in each depth distance range, the angle relationship model corresponding to the depth distance is selected according to the corresponding relationship, and then the screen display area corresponding to the relative angle is selected according to the selected angle relationship model. The angle relation model refers to an angle range corresponding to a screen display area, that is, when the relative angle is within the angle range, the screen display area corresponding to the angle range is displayed.
It can be understood that the screen display area can be adjusted according to the user position according to the different user positions, and the change of the screen display area can be regarded as the change of the display position, so as to achieve the best viewing effect. For example, when the user moves a small distance, the screen display areas corresponding to the two movements may overlap.
By way of specific example and not limitation, 5 display areas, namely a first display area, a second display area, a third display area, a fourth display area and a fifth display area, are set on the curved screen in advance. The five display areas may have overlapping portions due to the design of the curved screen, where the display area of the curved screen is displayed corresponding to the position of the user according to the position of the user, where the first display area is the leftmost screen display area of the curved screen, as shown in fig. 5. The second display area is the left screen display area of the curved screen, as shown in fig. 6. The third display area is the central screen display area of the curved screen, as shown in fig. 7. The fourth display area is the off-right screen display area of the curved screen, as shown in fig. 8. The fifth display area is the rightmost screen display area of the curved screen, as shown in fig. 9. Then, setting a corresponding relationship between the depth distance and the angle relationship model, for example, setting the corresponding angle relationship model to be displayed in the third display area when the relative angle is in the range of-6 ° to 6 ° when the depth distance is detected to be in the range of 35 to 55; displaying in the second display area when the relative angle is in a range of-6 degrees to-9 degrees (including-6 degrees); displaying in the first display area when the relative angle is less than or equal to-9 degrees; displaying in the fourth display area when the relative angle is in a range of 6 ° to 9 ° (including 6 °); and displaying in the fifth display area when the relative angle is greater than or equal to 9 degrees.
According to the setting, when the depth distance is detected to be 40cm, the depth distance accords with the set range, and the angle relation model is selected. If the relative angle is detected to be 0 °, displaying the image in a third display area according to the angle relationship model, as shown in fig. 10, where fig. 10 is a screen display area of the curved screen when the relative angle between the face and the camera is 0 °. If the relative angle is detected to be minus 6 degrees, displaying the image in a second display area according to the angle relation model, as shown in fig. 11, where fig. 11 is a screen display area of the curved screen when the relative angle between the human face and the camera is minus 6 degrees. If the relative angle is detected to be-9 degrees, displaying the image in a first display area according to the angle relation model, as shown in fig. 12, where fig. 12 is a screen display area of the curved screen when the relative angle between the face and the camera is-9 degrees.

In this embodiment, when the screen display area is smaller than or equal to the preset area threshold, if two or more faces exist in the current image, the distance between the at least two faces is obtained, and if it is detected that the distance between the two faces exceeds the preset distance threshold, the two faces whose distance exceeds the preset distance threshold can be detected respectively, and the depth distance and the relative angle between the two faces and the camera are determined, so that the corresponding screen display areas are determined respectively and displayed on the curved screen respectively. For example, the rightmost screen display area of the curved screen in fig. 9 and the leftmost screen display area of the curved screen in fig. 5 may be displayed simultaneously. It is understood that, in the case of realizing simultaneous display of the two screen display areas, the setting is determined according to the set size of the screen display area, and if the screen display area is too large, the display areas overlap each other when the two areas are simultaneously displayed, so that the setting of the area threshold is determined according to the length of the curved screen, and the value of the area threshold is generally less than or equal to 1/2 of the length of the curved screen. Similarly, the preset distance threshold may be comprehensively analyzed according to the size of the curved screen and the size of the screen display area, so as to be set.
