The method includes: after the camera is started and the indicator light is in a lit state, obtaining the environmental information collected by the environmental sensor; and if it is determined according to the environmental information that the condition for closing the camera is met, controlling the camera to close.

[0027] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0028] Please refer to Figure 1 , Figure 1A flowchart of a head mounted display device control method provided in an embodiment of the present application.

[0029] like Figure 1 As shown, the head mounted display device control method includes steps S101 to S102.

[0030] Step S101: After the camera is started and the indicator light is on, environmental information collected by the environmental sensor is obtained.

[0031] The head-mounted display device control method is applied to a head-mounted display device, and the head-mounted display device includes a camera, an indicator light, and an environmental sensor. The camera is used to collect images of the surrounding environment, and the camera includes but is not limited to a monocular camera, a binocular camera, and a trinocular camera. The indicator light is used to remind the surrounding personnel that the camera is turned on or off, wherein the indicator light is in a lit state to indicate that the camera is turned on, and the indicator light is in an off state to indicate that the camera is turned off. The indicator light includes but is not limited to a constant light indicator and a flashing indicator light. The type of the indicator light can be selected according to actual conditions, and the embodiment of the present invention does not specifically limit this. For example, the indicator light can be an LED light. The environmental sensor is used to collect environmental information of the environment, wherein when the environmental sensor is a light sensor, the environmental information is the brightness of the surrounding environment, and when the environmental sensor is a distance sensor, the environmental information is the distance between the distance sensor and the obstacle in the detection direction.

[0032] In some embodiments, the environmental sensor is arranged near the indicator light, and the distance between the environmental sensor and the indicator light can be set according to actual conditions. For example, the distance between the environmental sensor and the indicator light is set to 2 mm. The environmental information detected by the environmental sensor is used as the environmental information of the position of the indicator light. When the environmental sensor is closer to the indicator light, the environmental information of the position of the indicator light is more accurate. The indicator light and the environmental sensor are arranged on the side facing away from the wearer (that is, the side facing the surrounding people), so that the surrounding people can see the prompt light emitted by the indicator light, and the environmental sensor can collect the surrounding environmental information. In one embodiment, the head-mounted display device is AR glasses. In this case, the indicator light and the environmental sensor can be arranged on the front of the AR glasses frame, that is, the indicator light and the environmental sensor are arranged on the side of the AR glasses frame away from the temples.

[0033] In some embodiments, an indicator light and an environmental sensor are disposed on the front of the head mounted display device, so that people around can see the prompt light emitted by the indicator light and the environmental sensor can collect surrounding environmental information.

[0034] In some embodiments, a baffle may be provided between the environmental sensor and the indicator light. The baffle can effectively reduce the interference of the light emitted by the indicator light on the environmental sensor, making the environmental sensor more accurate in collecting environmental information.

[0035] In some embodiments, the indicator light and the environmental sensor are disposed on the front surface of the head-mounted display device. The indicator light and the environmental sensor are disposed close to each other and in the same hardware hole of the head-mounted display device. The hardware hole is used to place a hardware device. The light emitted by the indicator light in the hardware hole irradiates out through the hole opening, and the environmental sensor in the hardware hole collects environmental information through the hole opening.

[0036] Exemplarily, as Figure 2 shown, the head-mounted display device 100 includes a camera 11, an indicator light 21, and an environmental sensor 31. The camera 11, the indicator light 21, and the environmental sensor 31 are disposed on the front surface of the head-mounted display device 100, that is, on the side of the head-mounted display device 100 facing the surrounding people. The camera 11 is used to collect images of the surrounding environment. The indicator light 21 can emit a prompt light for reminding the surrounding people that the camera is turned on or off. The environmental sensor 31 is used to collect environmental information of the surrounding environment. As Figure 3 shown, a baffle 41 is provided between the environmental sensor 31 and the indicator light 21. The baffle 41 can block the prompt light emitted by the indicator light 21 from irradiating on the environmental sensor 31.

[0037] It should be noted that Figure 2 the AR glasses are taken as an example for illustration in Figure 2 . Of course, the head-mounted display device 100 can also be other forms of devices. The embodiments of the present application do not make specific limitations in this regard. For example, the head-mounted display device 100 can also be an AR helmet, etc. The areas of the camera 11, the indicator light 21, and the environmental sensor 31 in the head-mounted display device 100 can be set according to actual situations. The embodiments of the present application do not make specific limitations in this regard. In some embodiments, as Figure 4 shown, the camera 11, the indicator light 21, and the environmental sensor 31 are disposed in area A. In some other embodiments, as

[0038] shown, the camera 11, the indicator light 21, and the environmental sensor 31 can be disposed in area B.

[0039] In some embodiments, when the indicator light is in the lit state, it is determined that the camera has been turned on, and environmental information of the environment where the head-mounted display device is located is collected through an environmental sensor.

[0040] In some embodiments, the environmental sensor includes a first light sensor. When the indicator light is in the lit state, it is determined that the camera has been turned on, and the first brightness of the environment where the head-mounted display device is located is collected through the first light sensor.

[0041] In some embodiments, the environmental sensor includes a distance sensor. When the indicator light is in the lit state, it is determined that the camera has been turned on, and a distance is collected through the distance sensor. Wherein, the distance represents the distance between the distance sensor and an obstacle in the detection direction, that is, the distance between the head-mounted display device and the obstacle.

[0042] In some embodiments, the environmental sensor includes a first light sensor and / or a distance sensor. When the indicator light is in the lit state, it is determined that the camera has been turned on, and the first brightness of the environment where the head-mounted display device is located is collected through the first light sensor, and / or the distance between the head-mounted display device and an obstacle is collected through the distance sensor.

[0043] Step S102: If it is determined that the condition for turning off the camera is met according to the environmental information, control the camera to turn off.

[0044] Wherein, the condition for turning off the camera is that the indicator light is blocked and / or the environmental sensor is blocked.

[0045] In some embodiments, when the first brightness is less than or equal to a preset brightness threshold, it is determined that the condition for turning off the camera is met. When the first brightness is greater than the preset brightness threshold, it is determined that the condition for turning off the camera is not met. Wherein, the preset brightness threshold can be set according to actual situations, and the embodiments of the present invention do not make specific limitations thereto. For example, the preset brightness threshold can be set to 50 lux.

[0046] Exemplarily, when the first brightness is less than or equal to the preset brightness threshold, it can be further determined that the first light sensor is blocked and the indicator light in the close position is also blocked. The first brightness collected through the first light sensor can accurately know whether the indicator light is blocked and / or whether the environmental sensor is blocked.

[0047] In some embodiments, an environmental image of the surrounding environment is collected through the camera; the preset brightness threshold is determined according to the brightness of the environmental image. Wherein, the preset brightness threshold is less than the first brightness. Setting the preset brightness threshold according to the brightness of the environmental image can accurately determine whether the condition for turning off the camera is met.

[0048] In some embodiments, the method for determining a preset brightness threshold according to the brightness of an environmental image may be as follows: perform color analysis on the environmental image, determine the environmental brightness according to the brightness and saturation of the image in the color analysis, obtain a mapping relationship table between the preset environmental brightness and the preset brightness threshold, and query the preset brightness threshold corresponding to the environmental brightness from the mapping relationship table. Among them, the mapping relationship table is established based on the environmental brightness and the preset brightness threshold. By performing brightness analysis on the environmental image, the preset brightness threshold can be accurately set.

[0049] It should be noted that the brightness of the environmental image can also be determined by: identifying the environmental image through a neural network model to obtain the environmental brightness. The neural network model is a pre-established brightness recognition model, and the neural network model includes, but is not limited to, a convolutional neural network model, a recurrent convolutional neural network model, and the like.

[0050] In some embodiments, when the distance is less than or equal to a preset distance threshold, it is determined that the condition for closing the camera is met; when the distance is greater than the preset distance threshold, it is determined that the condition for closing the camera is not met. Among them, the preset distance threshold can be set according to the actual situation, and the embodiments of the present invention do not make specific limitations in this regard. For example, the preset distance threshold can be set to 0.2 meters. When the distance is less than or equal to the preset distance threshold, it is determined that there is an obstacle blocking the measurement direction of the distance sensor, and the indicator light in the close position is also blocked by the obstacle.

[0051] In some embodiments, when the first brightness is less than or equal to the preset brightness threshold and the distance is less than or equal to the preset distance threshold, it is determined that the condition for closing the camera is met; when the first brightness is less than or equal to the preset brightness threshold and the distance is greater than the preset distance threshold, it is determined that the condition for closing the camera may be met; when the first brightness is greater than the preset brightness threshold and the distance is less than or equal to the preset distance threshold, it is determined that the condition for closing the camera may be met; when the first brightness is greater than the preset brightness threshold and the distance is greater than the preset distance threshold, it is determined that the condition for closing the camera is not met. By using the first light sensor and the distance sensor to determine whether the condition for closing the camera is met, the accuracy of controlling the camera can be improved.

[0052] In some embodiments, the environmental sensor includes a first light sensor and a second light sensor. The second light sensor is arranged away from the first light sensor. The first brightness is collected by the first light sensor, and the second brightness is collected by the second light sensor. Whether the condition for closing the camera is met is determined according to the first brightness and the second brightness. By the first brightness and the second brightness, it can be accurately determined whether the condition for closing the camera is met.

[0053] Exemplarily, such as Figure 5As shown, the second light sensor 32 is disposed away from the first light sensor 31 in the head-mounted display device 100, and the second light sensor 32 and the first light sensor 31 are spaced apart by a preset distance. The preset distance can be set according to actual situations, and the embodiments of the present application do not make specific limitations thereto. For example, the preset distance can be set to 2 centimeters. By setting light sensors at different positions and comparing the brightnesses collected by the two light sensors at different positions, it is possible to accurately know whether the condition for turning off the camera is met.

[0054] In some embodiments, the method for determining whether the condition for turning off the camera is met based on the first brightness and the second brightness may be: subtracting the first brightness from the second brightness to obtain a brightness difference. If the brightness difference is greater than a preset first brightness difference, it is determined that the condition for turning off the camera is met; if the brightness difference is less than a preset second brightness difference, it is determined that the condition for turning off the camera is not met. Among them, the preset first brightness difference can be set according to actual situations, and the embodiments of the present invention do not make specific limitations thereto. For example, the preset first brightness difference can be set to 10 lux. By detecting the brightness difference in different regions, it is possible to accurately determine whether the condition for turning off the camera is met.

[0055] In some embodiments, when it is determined that the condition for turning off the camera is met, the camera is controlled to be turned off to avoid the camera from collecting the privacy information of surrounding people, thereby effectively protecting the privacy information of surrounding people.

[0056] Exemplarily, when it is determined that the environmental sensor is blocked, the camera is controlled to be turned off. And / or, when it is determined that the indicator light is blocked, the camera is controlled to be turned off to avoid the camera from collecting the privacy information of surrounding people, thereby effectively protecting the privacy information of surrounding people.

[0057] In some embodiments, the head-mounted display device further includes a sound playback device. After the camera is started and the indicator light is in the lit state, the sound playback device is controlled to output a prompt sound indicating that the camera has been turned on. Among them, the prompt sound includes but is not limited to a prompt language and a prompt indicator sound. For example, the prompt language can be a voice indicating that the camera has been turned on, and the prompt indicator sound can be a "beep" sound. By outputting a prompt sound through the sound playback device, it is possible to effectively remind surrounding people that the camera is turned on, so that surrounding people can enhance their privacy protection awareness and avoid the camera from collecting the privacy information of surrounding people, thereby effectively protecting the privacy information of surrounding people.

[0058] In some embodiments, the sound playback device is controlled to output the prompt sound indicating that the camera has been turned on at intervals of a preset time to remind surrounding people that the camera has been turned on. Among them, the preset time can be 1 minute. By outputting the prompt sound indicating that the camera has been turned on at intervals of a preset time, it is possible to not only effectively remind surrounding people that the camera is turned on, but also reduce the energy consumption of the head-mounted display device.

[0059] In some embodiments, when it is determined that the indicator light may be blocked, the sound playback device is controlled to output a prompt sound indicating that the camera has been turned on. When the indicator light may be blocked, outputting the prompt sound indicating that the camera has been turned on can ensure that people around are reminded that the camera is on, enabling people around to enhance their privacy protection awareness, avoid the camera from collecting the privacy information of people around, and thus effectively protect the privacy information of people around.

[0060] In some embodiments, after controlling the camera to turn off, the environmental sensor is controlled to enter the sleep state to reduce the power consumption of the head-mounted display device.

[0061] In some embodiments, after controlling the camera to turn off, after a preset time period, the environmental sensor is controlled to enter the working state, and the current environmental information collected by the environmental sensor is obtained; if it is determined that the condition for turning on the camera is met according to the current environmental information, the camera is controlled to work. Herein, the preset time period can be set according to the actual situation, and the embodiments of the present application do not make specific limitations thereto. For example, the preset time period can be set to 3 minutes. The environmental sensor is re-awakened, and the current environmental information is collected through sensor sensing, so as to accurately know whether to turn on the camera, thereby improving the usage experience of the wearer wearing the head-mounted display device.

[0062] In some embodiments, the environmental sensor includes a first light sensor. After a preset time period, the first light sensor is controlled to enter the working state, and the third brightness collected by the first light sensor is obtained; when the third brightness is less than or equal to the preset brightness threshold, it is determined that the condition for turning on the camera is not met. When the third brightness is greater than the preset brightness threshold, it is determined that the condition for turning on the camera is met. By awakening the first light sensor and based on the third brightness collected by the first light sensor, it can be accurately known whether the camera needs to be turned on.

[0063] In some embodiments, the environmental sensor includes a distance sensor. After a preset time period, the distance sensor is controlled to enter the working state, and the current distance collected by the distance sensor is obtained. When the current distance is less than or equal to the preset distance threshold, it is determined that the condition for turning on the camera is not met; when the distance is greater than the preset distance threshold, it is determined that the condition for turning on the camera is met. Herein, the preset distance threshold can be set according to the actual situation, and the embodiments of the present invention do not make specific limitations thereto. For example, the preset distance threshold can be set to 0.2 meters. By awakening the distance sensor and based on the current distance collected by the distance sensor, it can be accurately known whether the camera needs to be turned on.

[0064] The head-mounted display device control method provided in the above embodiment obtains the environmental information collected by the environmental sensor after the camera is started and the indicator light is in the lit state; if it is determined according to the environmental information that the condition for closing the camera is met, the camera is controlled to close. In the present application, the environmental information collected by the environmental sensor is used, and it can be accurately determined whether the condition for closing the camera is met according to the environmental information. When the condition for closing the camera is met, the camera is controlled to close, avoiding the camera from collecting the privacy information of surrounding people, and thus effectively protecting the privacy information of surrounding people.
