Fig. 2 is a schematic flow chart illustrating a VR display method according to an embodiment of the present invention. The method may be applied to the VR display system 100 of fig. 1. As shown in fig. 2, the method includes:
step 210, the second device obtains first display content on a first screen of the first device, wherein the first display content includes parameter information of a plurality of pixel points.
The first display content on the first screen refers to all content currently displayed on the first screen. When the first screen comprises a plurality of first display screens, the first display content is the content on all the first display screens. The first device may send the first display content to the second device after the first device establishes a connection with the second device.
Of course, before the second device obtains the first display content on the first screen of the first device, the second device needs to be connected with the first device. Wherein the first device may pre-store a connectable device identification list, so that the first device may determine whether to accept the connection of the second device by looking up the device identification in the device identification list.
Wherein, step 210 specifically includes:
step 211, obtaining an original content corresponding to the first display content.
The original content corresponding to the first display content refers to a content resource from which the first display content can be obtained after the first device is processed, that is, the original content is unprocessed. The method further comprises: the method comprises the steps that the first equipment obtains original content, obtains user gestures, processes the original content according to the user gestures to obtain first display content, and sends the first display content to the second equipment. The original content may be sent to the first device by another device (e.g., the second device), or may be generated by the first device according to an image captured by the camera of the first device.
Step 212, determine a first starting pixel point and a first maximum pixel point in the first screen.
The first starting pixel point and the first maximum pixel point refer to two vertex points in the first screen. For example, when the first screen includes two first display screens and the first display screens are rectangular, the two display screens respectively display left and right eye images, the first starting pixel point may be a left upper vertex point of the left first display screen, and the first largest pixel point may be a right lower vertex point of the left first display screen, or the first largest pixel point may be a right lower vertex point of the right first display screen; for another example, when the first screen includes two first display screens and the first display screens are circular, the first start pixel point and the first maximum pixel point may be two vertices on one diameter of the first display screen. In this step, the determining a first starting pixel point and a first maximum pixel point in the first screen may specifically be: and acquiring a first screen coordinate system, and determining the coordinates of the first initial pixel point and the first maximum pixel point in the first screen coordinate system. For example, in the first screen coordinate system, the coordinates of the first start pixel point and the first maximum pixel point are determined to be (m) respectively1,n1)、(m2,n2). As another example, in a first screen coordinate system, a first starting pixel point and a first maximum are determinedThe coordinates of the pixel points are (0,0) and (m) respectively2,n2)。
Step 213, in the original content, a first original pixel point corresponding to the first original pixel point is obtained, and a second original pixel point corresponding to the first maximum pixel point is obtained.
The first display content displayed in the first screen is converted from part or all of the original content, so that the pixel point corresponding to the first display content can be found in the original content. Therefore, in this step, in the original content, a first original pixel point corresponding to the first original pixel point is obtained, and a second original pixel point corresponding to the first maximum pixel point is obtained, which may specifically be: and in the original content coordinate system, determining the coordinates of the first original pixel point and the second original pixel point according to the coordinates of the first original pixel point and the first maximum pixel point in the first screen coordinate system. For example, in the original content coordinate system, the first original pixel point and the second original pixel point are respectively determined to be (x)1,y1)、(x2,y2)。
And 214, determining a display area in the original content according to the first original pixel point and the second original pixel point.
In this step, a display area similar to the shape of the first screen can be determined in the original content according to the coordinates of the first original pixel point and the second original pixel point.
Step 215, obtaining parameter information of each pixel point in the display area, thereby obtaining the first display content.
The parameter information of the pixel point comprises a pixel identification, a skew angle and a color parameter. The pixel identification can be the coordinate of the pixel point in the original content coordinate system; the skew angle may be an offset angle of the pixel point from the center of the original content field of view; the color parameter may be an RGB value of the pixel point. Step 215 may specifically include:
step 2151, determining pixel identification of a pixel point;
step 2152, determining a skew angle of a pixel point according to eyeball focus information of the first device;
and step 2153, determining color parameters of the pixel points according to the original content.
The pixel identifier (x, y) of the pixel point can be determined according to the coordinate of the pixel point in the original content coordinate system. The eyeball focus information of the first device can be obtained by acquiring sensor information arranged on the first device, and then the offset angle between the pixel point and the center of the original content view field, namely the skew angle of the pixel point, can be determined according to the eyeball focus information of the first device. For example, if the original content field center coordinate is (0,0) and the pixel point is (x, y), the skew angle of the pixel point is θ, which is arctan (y/x). And determining the color parameters (R, G, B) of the pixel points according to the RGB values of the pixel points in the original content.
And step 220, the second device determines second display content according to the parameter information of the pixel point, and displays the second display content on a second screen of the second device.
The second display content refers to content required to be displayed on a second screen of the second device. When the second screen includes a plurality of second display screens, the contents displayed on the respective second display screens may be the same.
Wherein, step 220 may specifically include:
step 221, determining a second initial pixel point and a second maximum pixel point in the second screen.
The second initial pixel point and the second maximum pixel point refer to two vertex points in the second screen. Step 221 may specifically be: and determining a second screen coordinate system, and determining the coordinates of a second initial pixel point and a second maximum pixel point in the second screen coordinate system.
Step 222, determining the intermediate content according to the pixel identification of the pixel point, the color parameter of the pixel point, the first original pixel point, the second initial pixel point and the second maximum pixel point.
Wherein the intermediate content is the conversion of the first display content into the second display contentData in the process. In this step, the following steps may be specifically performed: determining the proportional relation of a first screen and a second screen according to the coordinates of a first original pixel point, a second initial pixel point and a second maximum pixel point, and determining the pixel identification of the pixel point of the intermediate content according to the pixel identification of the pixel point of the first display content and the proportional relation of the first screen and the second screen; and determining the color parameters of the pixel points of the intermediate content according to the corresponding relation between the pixel points of the first display content and the pixel points of the intermediate content. For example, assume that the coordinates of the first original pixel, the second original pixel, and the second maximum pixel are (x)1,y1)、(x2,y2)、(u1,v1)、(u2,v2) If the pixel identifier of the pixel of the first display content is (x, y), and the pixel identifier of the pixel of the intermediate content corresponding to (x, y) is (u, v), u is (u ═ v)2-u1)*x/(x2-x1)，v＝(v2-v1)*y/(y2-y1)。
And 223, determining the rotation angle according to the oblique deflection angle of the pixel point.
The rotation angle is calculated according to the following formula:
α＝θ*[(u2-u1)(v2-v1)]/[(x2-x1)(y2-y1)]
wherein (x)1,y1) (x) is the coordinate of the first original pixel point2,y2) (u) is the coordinate of the second original pixel point1,v1) (u) is the coordinate of the second starting pixel point2,v2) And theta is the coordinate of the second maximum pixel point and is the skew angle.
And 224, rotating the intermediate content according to the rotation angle, and determining the rotated intermediate content as second display content.
And after the intermediate content is displayed according to the pixel identification and the color parameter of each pixel point of the intermediate content, rotating the intermediate content according to the rotation angle, and determining the rotated intermediate display content as second display content.
In some other embodiments, the rotation angle of each pixel point in the intermediate content may also be determined, and each pixel point in the intermediate content may be displayed according to the corresponding rotation angle, thereby generating the second display content.
According to the embodiment of the invention, the first display content on the first screen of the first device is acquired through the second device, wherein the first display content comprises parameter information of a plurality of pixel points, the second display content is determined according to the parameter information of the pixel points, and the second display content is displayed on the second screen of the second device, so that a user of the second device can also watch the content watched by the user of the first device, other people except a wearer of the VR device can watch the display content of the VR device, and the display content of the second device and the display content of the first device can keep the same visual angle.
Fig. 3 is a flowchart illustrating a VR display method according to another embodiment of the present invention. The method may be applied to the VR display system 100 of fig. 1. The difference from the above embodiment is that, as shown in fig. 3, the method further includes:
step 310, the second device receives a transformation control instruction for the object in the second display content.
Wherein the user may trigger a transformation control instruction on the second device for the object in the second display content. The transformation control instruction may include one or more of a movement control instruction, a rotation control instruction, an enlargement control instruction, a reduction control instruction, and a color change control instruction, so as to perform operations such as moving, rotating, enlarging, reducing, changing color, and the like on the object in the second display content.
And step 320, the second device performs transformation processing on the object in the second display content according to the transformation control instruction so as to update the second display content.
And when the conversion control instruction is received, the second equipment performs corresponding conversion processing on the object in the second display content according to the conversion control instruction, so that the second display content is updated. For example, assuming that the conversion control instruction is a movement control instruction, coordinates of each pixel point representing the object are converted to move the object, and after the object is moved, the rotation angle of the object may be adaptively changed according to the current position of the object, so as to update the second display content.
And step 330, the second device determines the updated parameter information of the pixel point according to the updated second display content.
The updated parameter information of the pixel point may include an updated pixel identifier, an updated skew angle, and an updated color parameter. The second device may obtain parameter information of each updated pixel point according to the updated second display content.
Step 340, the second device sends the updated parameter information of the pixel point to the first device, so that the first device updates the first display content according to the updated parameter information of the pixel point.
The updating of the first display content by the first device according to the updated parameter information is the reverse process of step 220, and is not described here again.
The embodiment of the invention receives a transformation control instruction aiming at an object in second display content through the second equipment, transforms the object in the second display content according to the transformation control instruction to update the second display content, determines the parameter information of an updated pixel point according to the updated second display content, and transmits the parameter information of the updated pixel point to the first equipment, so that the first equipment updates the first display content according to the parameter information of the updated pixel point, thereby not only enabling a user of the second equipment to watch the content watched by the user of the first equipment, but also enabling other people except a wearer of the VR equipment to watch the display content of the VR equipment, enabling the display content of the second equipment and the display content of the first equipment to keep the same visual angle, and also enabling the user of the second equipment to control an object in the content watched by the user of the first equipment, enabling other people than the wearer of the VR device to interact with the wearer of the VR device.
