[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] It is understood that although the functional modules are divided in the device schematic diagram and the logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flow chart. The terms "first", "second", etc. in the specification, claims or the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0039] Naked-eye 3D displays are widely used in various fields such as advertising, media, demonstration teaching, exhibitions, and film and television. Different from traditional binocular 3D display technology, naked-eye 3D display has the unique characteristics of naked eyes, that is, the audience does not need to wear glasses or helmets to enjoy the 3D effect. In related technologies, naked-eye 3D displays can only display three-dimensional images from a single perspective and will not change with the user's movement, resulting in a reduced user experience.

[0040] Based on this, the present application discloses a method, apparatus, device and medium for displaying three-dimensional images. If the three-dimensional image on the display device is always maintained in one direction, it will cause the picture to deviate, and then the display effect will be reduced. Therefore, according to the user position and the initial three-dimensional image, the target three-dimensional image is determined and then displayed on the display device. That is, the three-dimensional image in the display device will change with the change of the user position, which can effectively improve the display effect of the three-dimensional image in the display device.

[0041] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0042] Reference Figure 1 , Figure 1 A schematic diagram of the structure of a display device provided in an embodiment of the present application.

[0043] It is understandable that the display device includes a horizontally arranged position sensing device 100 and a vertically arranged display device 200 , wherein when a user moves on the position sensing device 100 , the position sensing device 100 can obtain the user's position on the position sensing device 100 in real time.

[0044] Specifically, the position sensing device 100 includes a floor and a plurality of capacitive sensors arranged on the back of the floor. The plurality of capacitive sensors are connected to the same controller. The principle of the capacitive sensor is that when a human body is close to the capacitive body device, a certain capacitance will be formed between the two. Therefore, by detecting the change in capacitance on the capacitive sensor, it is sensed whether a human body is approaching. That is, the user's position can be determined by detecting the capacitance change of each capacitive sensor.

[0045] First, refer to Figure 2 , Figure 2 A flowchart of a three-dimensional image display method provided in an embodiment of the present application, the three-dimensional image display method can be applied to the above Figure 1 The display device of the present invention comprises but is not limited to the following steps:

[0046] Step S100, obtaining the user position of the user on the position sensing device;

[0047] Step S200 : determining a target three-dimensional image according to the user position and the initial three-dimensional image and displaying the target three-dimensional image on a display device.

[0048] It is understandable that if the three-dimensional image on the display device 200 always remains in one direction, when the user moves, the three-dimensional image on the display device 200 does not move with the user's movement, which will cause the display effect of the three-dimensional image to deteriorate, resulting in a deterioration in the user's experience. By setting the position sensing device 100 on the ground, the user's position can be obtained. Therefore, according to the user's position and the initial three-dimensional image, the target three-dimensional image can be determined and then displayed in the display device 200, so that the three-dimensional image in the display device 200 changes with the change of the user's position, effectively improving the user's experience.

[0049] It should be noted that the initial three-dimensional image may be a preset three-dimensional scene, or may be a real-time three-dimensional scene acquired by a remote camera device.

[0050] Specifically, Figure 3 As shown, Figure 3 A schematic diagram of the change of a target three-dimensional image after a user position changes provided in an embodiment of the present application. Figure 3The dotted line range is the initial three-dimensional image, the user's initial position is point A, the angle between point A and the left edge of the display device 200 and the angle between point A and the right edge of the display device 200 is the first horizontal angle, when the user is at point A, the target three-dimensional image is the image in the initial three-dimensional image with point A as the vertex and the first horizontal angle as the display range, that is, when the user is at point A, the target three-dimensional image is the image within the first line segment 310, the second line segment 400 and the third line segment 410. The user moves from point A to point B, the angle between point B and the left edge of the display device 200 and the angle between point B and the right edge of the display device 200 is the second horizontal angle, when the user is at point B, the target three-dimensional image is the image in the initial three-dimensional image with point B as the vertex and the second horizontal angle as the display range, that is, when the user is at point B, the target three-dimensional image is the image within the first line segment 310, the fourth line segment 500 and the fifth line segment 510. From Figure 3 It can be clearly seen that when the user moves, the target three-dimensional image will change with the change of the user's position. In the case where the initial three-dimensional image remains unchanged, the user's visual effect will also change. Among them, the first line segment 310, the second line segment 400, the third line segment 410, the fourth line segment 500 and the fifth line segment 510 are only schematic line segments of the two-dimensional plane. In the three-dimensional image, the first line segment 310, the second line segment 400, the third line segment 410, the fourth line segment 500 and the fifth line segment 510 are represented as corresponding planes.

[0051] Specifically, Figure 4 As shown, Figure 4 A schematic diagram of the change of a target three-dimensional image after a user position changes is provided in another embodiment of the present application. Figure 4 The middle dotted line range is the initial three-dimensional image, the initial position of the user is point A, the angle between point A and the upper edge of the display device 200 and between point A and the lower edge of the display device 200 is the first vertical angle, when the user is at point A, the target three-dimensional image is the image in the initial three-dimensional image with point A as the vertex and the first vertical angle as the display range, that is, when the user is at point A, the target three-dimensional image is the image within the sixth line segment 320, the seventh line segment 420, and the eighth line segment 430. The user moves from point A to point B, the angle between point B and the upper edge of the display device 200 and between point B and the lower edge of the display device 200 is the second vertical angle, when the user is at point B, the target three-dimensional image is the image in the initial three-dimensional image with point B as the vertex and the second vertical angle as the display range, that is, when the user is at point B, the target three-dimensional image is the image within the sixth line segment 320, the ninth line segment 520, and the tenth line segment 530. Among them, the sixth line segment 320, the seventh line segment 420, the eighth line segment 430, the ninth line segment 520 and the tenth line segment 530 are only schematic line segments of the two-dimensional plane. In the three-dimensional image, the sixth line segment 320, the seventh line segment 420, the eighth line segment 430, the ninth line segment 520 and the tenth line segment 530 are represented as corresponding planes.

[0052] It should be noted that when calculating the vertical angle, the calculation can be performed based on the vertical position point of the user's position, wherein the vertical position point can be a preset vertical position point, for example, the vertical position point is a point 1.5 meters away from the position sensing device in the vertical direction, that is, Figure 4 As shown, when calculating the first vertical angle at point A, the angle between the vertical position point at point A (the point at which point A is 1.5 meters away from the position sensing device in the vertical direction) and the upper edge and the lower edge of the display device 200 is taken as the first vertical angle; similarly, when calculating the second vertical angle at point B, the angle between the vertical position point at point B (the point at which point B is 1.5 meters away from the position sensing device in the vertical direction) and the upper edge and the lower edge of the display device 200 is taken as the second vertical angle. For another example, the display device may further include a height sensor, which is used to obtain the height of the user in the position sensing device, and when calculating the vertical angle, the calculation may be performed based on the height of the user.

[0053] It should be noted that when the user is at point A, the target 3D image is the image in the initial 3D image with point A as the vertex and the first vertical angle and the first horizontal angle as the display range. When the user moves from point A to point B, the target 3D image is the image in the initial 3D image with point B as the vertex and the second vertical angle and the second horizontal angle as the display range.

[0054] It should be noted that when the user moves on the position sensing device 100, the capacitance changes of each capacitive sensor in the position sensing device 100 are not the same, so the user's position can be determined by detecting the capacitance changes of each capacitive sensor. For example, when the user is at point A, the capacitance of the capacitive sensor at point A will change, and when the user moves from point A to point B, the capacitance at point A becomes 0, and the capacitance of the capacitive sensor at point B will change, which can confirm that the user has moved from point A to point B.

[0055] Reference Figure 5 , Figure 5 A flowchart of a method for displaying a three-dimensional image provided in another embodiment of the present application includes but is not limited to the following steps:

[0056] Step S300: determining a moving speed of the viewing angle of the target three-dimensional image in the display device according to the user position and the preset initial position.

[0057] It can be understood that the initial three-dimensional image is a hemispherical three-dimensional scene with a radius of 100 meters, and the horizontal angle and vertical angle of the user at the initial position are both 60 degrees. Then the image displayed by the target three-dimensional image in the display device 200 is an image with a horizontal angle and a vertical angle of 60 degrees and a depth of 100 meters in the initial three-dimensional image with the initial position as the vertex. In actual display, the image in the depth direction will be compressed, and the compression will cause the image in the depth direction to be blurred. When the user moves forward, if the viewing angle of the target three-dimensional image can also follow the movement, that is, move in the depth direction, during the movement, the compressed image of the target three-dimensional image in the depth direction will be reduced, that is, the image in the depth direction will gradually become clear, improving the user's use effect. For example, when the user is in the initial position, the image of the target three-dimensional image in the depth direction is an image of 100 meters. If the user moves forward, the viewing angle of the target three-dimensional image follows the movement, and the image of the target three-dimensional image in the depth direction will decrease with the movement of the user. When the viewing angle of the target three-dimensional image moves forward by 20 meters, the image of the target three-dimensional image in the depth direction becomes an image of 80 meters. The size of the position sensing device 100 is fixed. If the movement of the viewing angle of the target three-dimensional image in the display device 200 is controlled according to the actual movement distance of the user on the position sensing device 100, the user may move to the edge of the position sensing device 100, but the viewing angle of the target three-dimensional image may move a short distance. Therefore, the moving speed of the viewing angle of the target three-dimensional image in the display device 200 may be determined according to the user position and the preset initial position.

[0058] It should be noted that if the initial 3D image has no boundary in the depth direction, when the user moves forward, the viewing angle of the target 3D image will follow the movement. During the movement, the image of the target 3D image will also change continuously, thereby improving the user experience.

[0059] Specifically, the user's moving distance may be calculated based on the user's position and the preset initial position, and then the moving speed of the viewing angle of the target three-dimensional image in the display device 200 may be determined based on the user's moving distance and the preset distance-speed relationship. For example, the distance-speed relationship may be that the moving speed increases by 1 meter per second for every 10 centimeters increase in the user's moving distance, that is, when the distance between the user's position and the initial position is 10 centimeters, the moving speed of the viewing angle of the target three-dimensional image in the display device 200 is 1 meter per second, and when the distance between the user's position and the initial position is 20 centimeters, the moving speed of the viewing angle of the target three-dimensional image in the display device 200 is 2 meters per second. Among them, the initial three-dimensional image is a hemispherical three-dimensional scene with a radius of 100 meters. The horizontal angle and vertical angle of the user at the initial position are both 60 degrees. The image content of the target three-dimensional image in the first second is an image with the initial position as the vertex, the horizontal angle and vertical angle are both 60 degrees, and the depth is 100 meters. If the user only moves forward 20 centimeters, then the image content of the target three-dimensional image in the second second is an image with the position 20 centimeters in front of the initial position as the vertex, the horizontal angle and vertical angle are both 60 degrees, and the depth is 98 meters; if the user moves forward 20 centimeters again, then the image content of the target three-dimensional image in the third second is an image with the position 40 centimeters in front of the initial position, the horizontal angle and vertical angle are both 60 degrees, and the depth is 94 meters; if the user no longer moves, then the image content of the target three-dimensional image in the fourth second is an image with the position 40 centimeters in front of the initial position, the horizontal angle and vertical angle are both 60 degrees, and the depth is 90 meters.

[0060] Reference Figure 6 , Figure 6 yes Figure 3 The specific flow chart of step S200 includes but is not limited to the following steps:

[0061] Step S210, obtaining a first distance between the user position and the display device;

[0062] Step S220, determining a first display boundary of the three-dimensional image according to the first distance and the initial three-dimensional image;

[0063] Step S230 : determining a target three-dimensional image according to the first display boundary and the initial three-dimensional image, and displaying the target three-dimensional image on a display device.

[0064] It can be understood that after determining the user position, the first distance between the user position and the display device 200 can be obtained first, wherein the first distance includes a first horizontal distance, a second horizontal distance, a first vertical distance and a second vertical distance, the first horizontal distance is the distance between the user position and the left edge of the display device 200, the second horizontal distance is the distance between the user position and the right edge of the display device 200, the first vertical distance is the distance between the user position and the upper edge of the display device 200, and the second vertical distance is the distance between the user position and the lower edge of the display device 200. After obtaining the first distance between the user position and the display device 200, since the size of the display device 200 is fixed, the horizontal angle and the vertical angle can be calculated through the first distance, and then the first display boundary of the three-dimensional image can be determined according to the user position, the horizontal angle and the vertical angle. Finally, the target three-dimensional image can be determined according to the first display boundary and the initial three-dimensional image. Among them, the first display boundary includes a left boundary, a right boundary, an upper boundary and a lower boundary, such as Figure 3 As shown, when the user position is point A, the left boundary is the second line segment 400, and the right boundary is the third line segment 410. Figure 4 As shown, when the user position is point A, the lower boundary is the seventh line segment 420, and the upper boundary is the eighth line segment 430. When the user position is point A, the image content of the target three-dimensional image is the image content within the second line segment 400, the third line segment 410, the seventh line segment 420, and the eighth line segment 430.

[0065] It should be noted that the display device further includes an image acquisition device, which can be used to acquire the action information of the user located on the position sensing device 100. Therefore, the first display boundary can also be updated according to the action information. For example, if the image acquisition device acquires the user's hand-raising action, the upper boundary of the first display boundary can be moved upward, and then the target three-dimensional image can be re-determined based on the updated first display boundary and the initial three-dimensional image and the target three-dimensional image can be displayed on the display device 200. For another example, if the image acquisition device acquires the user's pressing action, the lower boundary of the first display boundary can be moved downward, and then the target three-dimensional image can be re-determined based on the updated first display boundary and the initial three-dimensional image and the target three-dimensional image can be displayed on the display device 200.

[0066] Reference Figure 7 , Figure 7 A flowchart of a method for displaying a three-dimensional image provided in another embodiment of the present application includes but is not limited to the following steps:

[0067] Step S400 , determining a main display among multiple displays according to the action information, and displaying the target three-dimensional image on the main display.

[0068] It is understandable that the display device 200 may be composed of multiple displays, such as Figure 8 As shown, Figure 8 This is a schematic diagram of the structure of a display device provided by another embodiment of the present application. The position sensing device 100 is a square, and a first display 210, a second display 220, a third display 230, and a fourth display 240 are respectively arranged in four directions of the position sensing device 100. In the initial state, the first display 210 is the main display, and the target three-dimensional image is displayed in the first display 210. When the action information is that the user turns from facing the first display 210 to facing the second display 220, the second display 220 can be determined as the main display and the target three-dimensional image is displayed in the second display 220. By obtaining the user's action information, the main display is determined and the target three-dimensional image is displayed in the main display, so that when the user turns, the target three-dimensional image can also rotate with the user's rotation, thereby improving the user's use effect.
