[0041] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

The system is composed of a plurality of software and hardware modules, and is usually used in a computer, as shown in the figure. The method specifically comprises the following steps: Figure 1

[0044] S101, tracking the eyeball of a user and detecting the amplitude of shaking of a computer device

[0045] In some embodiments of the present application, a front camera capable of eyeball positioning and tracking can be installed on a display screen, and the naked-eye 3D display requirement is met through the positioning and tracking of the eyeball.

[0046] For example, in the embodiment of the present application, after the user starts the eyeball tracking system for naked-eye 3D display of the computer device in hand due to road bumps, the front camera of the display screen tracks and positions the eyeball of the user in real time, and the real-time distance between the eyeball of the user and the screen is detected and recorded. When the user uses the computer device, the naked-eye 3D display of the computer device is affected due to road bumps. The user manually starts the eyeball tracking system for naked-eye 3D display, and the naked-eye 3D display requirement of the user using the computer device is ensured through the analysis and processing of the system. At the same time, the system is started more in line with the user's requirement through the manual starting of the user, and the additional consumption of the power of the computer device and the computer analysis and operation resources caused by the automatic starting of the system due to the small bumps and shaking is avoided, the user's satisfaction is effectively improved, and the distance between the eyeball of the user and the screen of the computer device is detected in real time, so that the subsequent 3D analysis and processing are more in line with the naked-eye 3D display requirement of the user.

[0047] ​The amplitude of the shock of the computer device is detected, and the average amplitude of the shock of the computer device is calculated according to a specified time period; since the amplitude of the shock of the computer device caused by road bumps is irregular, the average amplitude of the shock of the computer device is calculated, so that the subsequent adjustment and analysis of the 3D naked eye device are more in line with the user's needs, and the average amplitude of the shock of the computer device is updated periodically, so that the naked eye 3D display analysis and processing are not prone to errors due to the continuous change of the road conditions and the delay of the average amplitude of the shock data, and the accuracy of the naked eye 3D display analysis and processing is effectively improved, and the user's satisfaction is greatly improved.

[0048] S102, naked eye 3D technology budget analysis and processing

[0049] For example, in the embodiment of the application, after obtaining the distance detection result between the user's eyeball and the screen of the computer device and the average amplitude of the shock of the computer device, the original direction information of the computer device before starting the naked eye 3D display eyeball tracking system is sensed, and the display screen of the computer device is divided into three vertical strip display areas with equal area;

[0050] After the division of the display area, the number of view points in each area is estimated when the computer device is in the opposite direction information of the original direction; when the computer device is in a shock state, the direction of the computer device at the next moment will be opposite to the current direction due to inertia, so the number of view points in each area is estimated when the computer device is in the opposite direction information of the current direction, and the subsequent view point arrangement result is obtained, so that the subsequent naked eye 3D effect analysis and processing of the computer is more efficient;

[0051] After receiving the estimated result of the view point arrangement, the pixel value in each area of the screen and the screen parameter of the computer device are further budgeted by combining the distance data between the user's eyeball and the screen of the computer device, and the budgeted result is stored; wherein the screen parameter of the computer includes the number of lines and the inclination angle of the cylindrical lens, so that the computer device can immediately adjust when processing the opposite direction information of the current direction, maintain the naked eye 3D display effect, and improve the user's viewing experience;

[0052] The above-mentioned preprocessing of the view point number arrangement result estimation, pixel value and computer device screen parameter is repeated within a specified time period, the naked eye 3D display in each direction relative to the original direction of the computer device is preprocessed, and the preprocessed result is stored; through the preprocessing, the analysis and adjustment to be performed to maintain the naked eye 3D display effect in each direction can be calculated in advance under the condition that the computer device shock amplitude does not exceed the set threshold within the period of time, the analysis and adjustment result can be quickly called when the computer device is in the corresponding direction information due to the subsequent jolt, and the real-time analysis and adjustment result leading to the naked eye 3D display effect cannot be maintained is avoided, and through the preprocessing, the use experience of the naked eye 3D display for the user can be effectively improved.

[0053] S103, performing adjustment management on the budget analysis result

[0054] For example, in the embodiment of the application, when the computer device is in the corresponding direction, the analysis and adjustment result of the direction is called, and the pixel value in each region of the computer device screen and the computer device screen parameter are adjusted according to the result;

[0055] In the analysis and adjustment process of the naked eye 3D display, the module completing the analysis process is in a wake-up state; since the road jolt is irregular, or the user's viewing posture changes and adjustment is not required, therefore, through the processing, quick analysis and adjustment can be performed immediately after the change occurs, and the display continuity and stability of the naked eye 3D are maintained.
