Detailed Description

For the purposes of making the objects, embodiments and advantages of the present application more apparent, an exemplary embodiment of the present application will be described more fully hereinafter with reference to the accompanying drawings in which exemplary embodiments of the application are shown, it being understood that the exemplary embodiments described are merely some, but not all, of the examples of the application.

It should be noted that the brief description of the terminology in the present application is for the purpose of facilitating understanding of the embodiments described below only and is not intended to limit the embodiments of the present application. Unless otherwise indicated, these terms should be construed in their ordinary and customary meaning.

Furthermore, the terms "comprise" and "have," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a product or apparatus that comprises a list of elements is not necessarily limited to those elements expressly listed, but may include other elements not expressly listed or inherent to such product or apparatus.

At present, for the positioning of the VR handle, six-dimensional pose estimation of the handle can be realized in a virtual reality scene through an LED and an inertial detection unit (Inertial Measurement Unit, IMU) arranged on the VR handle, so that positioning interaction of the VR space is realized.

Currently, the LEDs on the handle may be powered by a battery to illuminate the LEDs. For brightness control of the LED lighting, the power supply voltage of the LEDs is generally determined according to the number and distribution of the LEDs disposed on the handle. Specifically, the voltage provided by the battery can be boosted through the boosting chip so as to output the power supply voltage to the LED, so that the LED is lightened at a fixed voltage, that is, when the LED is turned on, the brightness of the LED is fixed, the brightness cannot be adjusted, and the adaptability of the LED to actual application scenes is poor.

Specifically, in a scene where the illumination intensity of the environment where the handle is located is strong, the LED recognition rate of the VR display device to the handle is reduced, so that the effect of six-dimensional (6 dof) pose estimation is affected. In a scene with weaker illumination intensity in the environment where the handle is positioned, if the handle is lightened according to fixed brightness, the brightness is too high, and unnecessary electricity consumption occurs.

Therefore, the handle provided by the embodiment of the application has the advantages that the ambient light detection component on the handle provided by the embodiment of the application is used for acquiring the illumination intensity of the environment where the handle is located, and then the power supply voltage of the LED is changed based on the illumination intensity, so that the brightness of the LED can be changed, the brightness can adapt to an actual application scene, the effect of six-dimensional pose estimation can be improved by improving the brightness of the LED in a scene with stronger illumination intensity, and the unnecessary lighting consumption can be reduced by reducing the brightness of the LED in a scene with weaker illumination intensity, so that the energy consumption is reduced.

The technical scheme of the present application will be described in detail with reference to specific examples. The following specific embodiments may be combined with each other or may exist independently, and the same or similar concepts or processes may not be repeated in some embodiments, and embodiments of the present application will be described below with reference to the drawings.

Fig. 1 is a schematic diagram of a VR system including a handle 10 and a VR display device 20 as shown in fig. 1, according to an example embodiment of the present application. As shown in fig. 1, a plurality of LEDs 101 are provided on the handle 10. The camera 202 on the VR display device 20 collects an image formed when the LED on the handle 10 is turned on, and then the image is analyzed according to a processor (not shown in the figure) on the VR display device 20 to realize positioning tracking of the handle 10, so as to realize positioning tracking of a moving target corresponding to the handle 10 in a virtual space range.

It is understood that the number and arrangement of the plurality of LEDs in fig. 1 is merely an example.

In one possible implementation, the plurality of LEDs may include 16 LEDs, wherein every 4 LEDs are connected in series to form a string of lights, and the formed strings of 4 strings of lights are connected in parallel to form a light ring. The LED lamp ring with the structure can improve the positioning precision of the VR display device 20 to the handle 10.

In one possible implementation, the handle 10 may also be provided with keys (not shown in fig. 1, with reference to fig. 9) including physical keys and/or touch keys by which a user may operate the VR display device.

Illustratively, the VR display device 20 may be a VR headset and the display 201 may be understood as a display screen on the VR headset for displaying an interface for VR headset indication display.

The display 201 may be an organic electroluminescent display (Organic Electroluminescence Display, OLED) or other types of displays, for example, and the application is not limited thereto.

The camera 202 is disposed on the VR display device 20 for acquiring image data formed when the LEDs on the handle 10 are lighted. For example, the camera 202 may be a binocular camera, and the model of the binocular camera may be selected according to actual needs, which is not limited by the present application.

Fig. 3 is a schematic structural diagram of a handle according to an embodiment of the present application, and as shown in fig. 3, the handle 10 includes a plurality of LEDs 101, an ambient light detecting component 102, a control component 103, and a driving circuit 104.

Wherein the plurality of LEDs 101 are configured to emit infrared rays when illuminated to assist in positioning the handle 10 by the VR display device corresponding to the handle 10.

An ambient light detection assembly 102 configured to obtain the intensity of illumination of the environment in which the handle 10 is located. By way of example, the ambient light detection component 102 can be an ambient light sensor.

The control component 103 is electrically connected to the ambient light detection component 102 and the driving circuit 104, respectively, and the control component 103 is configured to output a pulse width modulation (Pulse Width Modulation, PWM) signal according to the illumination intensity.

In one possible implementation, if the light intensity is above the preset light intensity value, which indicates that the light intensity of the environment where the current handle 10 is located is strong, the control component 103 may adjust the duty cycle of the PWM signal to be the first duty cycle. If the illumination intensity is not above the preset illumination intensity value, that is, if the illumination intensity is less than the preset illumination intensity value, it indicates that the illumination intensity of the environment where the handle 10 is located is weaker at this time, the control component 103 may adjust the duty cycle of the PWM signal to be a second duty cycle, where the first duty cycle is greater than the second duty cycle.

It will be appreciated that the above duty cycle refers to the ratio of the time taken up by the high level to one cycle time. Fig. 4 is a schematic diagram of PWM signals according to an example of the embodiment of the present application, and PWM signals corresponding to the first duty cycle and the second duty cycle may refer to fig. 4.

In one possible implementation, the ambient light detection component 102 may be coupled to the control component 103 via a two-wire serial bus (Inter-INTEGRATED CIRCUIT, I2C).

The first end of the first capacitor is connected with the first connecting wire, and the second end of the first capacitor is grounded.

Wherein the boosting component 41 is configured to boost a voltage supplied from an external power source based on the PWM signal, and output a target voltage for driving the plurality of LEDs to light.

The boost assembly 41 may be, for example, a chip having a boost function, and the application is not limited to the type of the chip selected.

It will be appreciated that "adapting" herein may mean that the brightness of the LED is more matched to the illumination intensity of the current application scene, and when the illumination intensity is higher, the brightness of the LED at this time will not affect the effect of 6dof pose estimation due to the lower brightness. When illumination intensity is lower, the brightness of the LED at the moment can not generate unnecessary electric quantity consumption due to the fact that the brightness is too high, so that the endurance time of an external power supply of the handle 10 is prolonged, and the requirement of the VR display device for identifying infrared rays emitted by the LED can be met by the brightness at the moment.

In one possible implementation, the external power source may be a 1.5V (volt) battery.

Therefore, the brightness of the LEDs on the handle is adjusted according to the illumination intensity of the environment where the handle 10 is positioned, so that the brightness can adapt to actual application scenes, and the use experience of a user can be improved.
