Specifically, if the temperature of the processing unit is not less than the temperature threshold, the rotation speed of the fan unit is not less than the rotation speed threshold, and the processing frequency of the graphics processing unit is not less than the frequency threshold, which indicates that it is difficult to increase the frame rate by lowering the temperature and increasing the processing frequency of the graphics processing unit 11, at this time, the displacement amount of the virtual reality device at the position of the previous frame and the current frame can be determined, and if the displacement amount is less than the displacement threshold, it indicates that the position of the virtual reality device does not change much, that is, the user head does not move significantly, so that the frame does not need to change significantly.
The following describes the control method of the embodiment of the present disclosure in detail:
in step S110, a current frame rate is determined according to a running time of a current frame of the target video.
The target video may be a video displayed on the display unit 3 after the virtual reality device runs the application program, that is, a video displayed according to the image data output by the graphics processing unit 11, and the specific content thereof is not particularly limited herein.
In some embodiments of the present disclosure, the current frame rate may be a quotient of 1 second divided by the operation duration of the current frame, for example, the operation duration of the current frame is 0.013 second, and the current frame rate is about 76 fps. Determining the current frame rate according to the running time of the current frame of the target video, i.e. step S110, may include step S1110 and step S1120, where:
step S1110, detecting the operation duration of the current frame.

As shown in fig. 4, the virtual reality apparatus may further include a temperature detection unit 5, a rotation speed detection unit 6, a frequency detection unit 7, and a position sensing unit 8, wherein:
in some embodiments of the present disclosure, the temperature detecting unit 5 may be a temperature sensor, which may be disposed on the same circuit board as the processing unit 1, or may be integrated in the processing unit 1, and may detect the temperature of the processing unit 1 in real time.
If the processing unit 1 includes only the gpu 11, the temperature of the processing unit 1 is the temperature of the gpu 11.
The rotation speed detection unit 6 may be connected to the fan unit 2 for detecting the rotation speed of the fan unit 2 in real time. The frequency detection unit 7 may be used to detect the processing frequency of the graphics processing unit 11 in real time.
In step S130, the current frame rate may be compared with the target frame rate, and if the current frame rate is less than the target frame rate, it is determined that the video may be jammed, at this time, a frame rate adjustment step may be performed to increase the frame rate, avoid the video from being jammed, and increase the smoothness. The target frame rate may be predetermined, for example, the target frame rate may be 75fps or 90 fps.
The frame rate adjusting step may comprise: if the temperature of the processing unit 1 is not less than the temperature threshold, the rotation speed of the fan unit 2 is not less than the rotation speed threshold, and the processing frequency of the graphic processing unit 11 is not less than the frequency threshold, it indicates that the frame rate cannot be increased by cooling and raising the frequency, so that the displacement of the virtual reality device between the current frame and the previous frame can be determined, and the displacement is compared with the displacement threshold; if the displacement is not greater than the displacement threshold, it indicates that the change of the position of the virtual reality device when the virtual reality device operates the previous frame and the current frame is not large, and it can be inferred that the change of the position of the next frame and the current frame is not large accordingly.
The displacement threshold may be an empirical value or a value set by the user, and the specific value is not particularly limited herein.
The movement of the virtual reality device may include translation and rotation, causing a change in the position of the virtual reality device. For example, the coordinates of the virtual reality device in a coordinate system may be generated according to the data sensed by the position sensing unit 8, and the coordinates may be used to represent the position of the virtual reality device, and the displacement of the virtual reality device may be determined by determining the change of the coordinates in the same coordinate system. The position sensing unit 8 may be one or more, and may be a position sensor or other devices capable of sensing a position change, and the specific number, position and structure thereof are not particularly limited as long as they can be used for sensing the position of the virtual reality device.
It should be noted that the movement of the virtual reality device is represented by a signal generated by the movement of the position sensing unit 8, that is, the position of the virtual reality device can be represented by the position of the position sensing unit 8, if the position sensing unit 8 senses a change in position, it is determined that the position of the virtual reality device has changed, and if the position sensing unit 8 does not sense a change in position, it is determined that the position of the virtual display device has not changed.
Further, in some embodiments of the present disclosure, the frame rate adjusting step may further include:
and if the displacement is larger than the displacement threshold, determining the rendering resolution of the next frame according to the rendering resolution of the current frame, wherein the rendering resolution of the next frame is smaller than that of the current frame.
If the displacement is greater than the displacement threshold, it can be considered that the displacement amplitude of the virtual reality device is large, and the image seen by the user should be changed correspondingly, and at this time, the rendering resolution can be reduced on the basis of the rendering resolution of the current frame as the rendering resolution of the next frame, so that the amount of calculation is reduced, and the frame rate is improved.
In some embodiments of the present disclosure, if the displacement amount is greater than the displacement threshold, a difference obtained by subtracting a fixed value from the rendering resolution of the current frame may be used as the rendering resolution of the next frame, so as to implement the rendering resolution of the next frame. Of course, in another embodiment of the present disclosure, if the displacement amount is greater than the displacement threshold, the rendering resolution of the current frame may be reduced according to a predetermined ratio to be used as the rendering resolution of the next frame.
In some embodiments of the present disclosure, the image distance of the virtual reality device is the distance between the virtual image and the lens unit 4. If the displacement is greater than the displacement threshold, whether the image distance of the virtual reality device is smaller than a preset appropriate distance can be further judged, if so, the person is in an appropriate viewing distance, at this time, for the case of a low frame rate, the reduction amplitude of the rendering resolution can be determined according to the distance difference between the appropriate distance and the image distance, and if the distance difference is larger, the reduction amplitude of the rendering resolution can be smaller. If the image distance is greater than the suitable distance, the rendering resolution may be reduced directly by a predetermined magnitude.
In some embodiments of the present disclosure, the frame rate may also be increased by lowering and raising the frequency, and lowering the frequency is prior to raising the frequency, and raising the frequency is prior to the above-mentioned alternate frame rendering. Specifically, as shown in fig. 2, steps S200 to S300 in fig. 2 illustrate a detailed principle of an execution sequence of operations in an embodiment of step S130, where if the current frame rate is less than the target frame rate, the temperature of processing unit 1 is compared with a temperature threshold, if the temperature of processing unit 1 is not less than the temperature threshold, the rotation speed of fan unit 2 is compared with a rotation speed threshold, and if the rotation speed of fan unit 2 is less than the rotation speed threshold, the rotation speed of fan unit 2 is increased, and the heat dissipation performance is improved, so that the frame rate is increased; if the rotation speed of the fan unit 2 is not less than the rotation speed threshold, the rotation speed of the fan unit 2 cannot be increased, the processing frequency of the graphic processing unit 11 may be compared with the frequency threshold, and if the processing frequency of the graphic processing unit 11 is less than the frequency threshold, the processing frequency of the graphic processing unit 11 may be increased, the computing capability may be improved, and the frame rate may be increased.
The specific value of the temperature threshold is not particularly limited, and may be 66 ℃ or less, for example, up to 115 ℃.
In some embodiments of the present disclosure, the number of the fan units 2 may be multiple, each fan unit 2 may include a fan blade and a motor for driving the fan blade to rotate, and each fan unit 2 may rotate independently. If the rotation speed of the fan unit 2 is less than the threshold rotation speed, the rotation speed of at least one fan unit 2 with the rotation speed less than the threshold rotation speed may be increased when the rotation speed of the fan unit 2 is increased.
The principle of adjusting the rotational speed of the fan unit 2 is exemplified below:
take fan unit 2 to include flabellum and drive the motor that the flabellum rotated, and the motor is for example direct current: the operating frequency of the motor can be adjusted according to the relationship between the operating voltage interval of the motor and the temperature, so that the rotating speed of the fan blades, namely the rotating speed of the fan unit 2, can be adjusted. For a dc motor: rotational speed
Where U is the armature voltage, I is the armature current, R is the resistance of the armature circuit,
is the excitation flux, and k is the induced electromotive force constant.
The method of adjusting the rotational speed of a motor may include: in the field control method for controlling the field magnetic flux Φ and the armature voltage control method for controlling the armature voltage U, the armature voltage is controlled by, for example, approximating n to kU, that is, n to kU, since the higher the voltage is, the higher the rotation speed is, and the load is constant, and the rated range is2Wherein k is a constant value coefficient.
For example, the motor operating voltage interval is 1.8v-3.3v, and n is 3.24k-10.89k according to the relationship between the voltage and the rotation speed of the motor, so that under the condition that the load of the fan unit 2 is constant, the rotation speed of the motor can be controlled by an execution unit, which can be a microprocessor, and the execution unit can be connected with the motor through a general purpose input/output port (GPIO), so that the rotation speed of the motor can be adjusted by controlling the output voltage of the general purpose input/output port of the execution unit.
Furthermore, in some embodiments of the present disclosure, the performing the frame rate adjustment step may further include:
if the temperature of the processing unit 1 is less than the temperature threshold, the processing frequency of the graphic processing unit 11 is compared with the frequency threshold, and if the processing frequency is less than the frequency threshold, the processing frequency of the graphic processing unit 11 is increased. Thereby improving the processing capacity and the frame rate.
It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
