Description

Technical Field

[0001] This application relates to the technical field of head-mounted display devices, and in particular, to an image display method, apparatus, head-mounted display device, and readable storage medium. Background Art

[0002] With the continuous development of technology, head-mounted display devices such as virtual reality (VR) devices and augmented reality (AR) devices are widely used in people's lives. Among them, the head-mounted display device can display images to the user through a carried display system. For example, taking AR glasses as an example, the near-eye imaging system in the AR glasses can superimpose the real picture of the environment where the AR is located and the virtual picture in the AR glasses, and then form a virtual image through a series of optical imaging elements in the near-eye imaging system for image display and project it into the human eye.

[0003] Currently, usually, the head-mounted display device will start the image display mode through a configured camera. For example, through a SLAM (simultaneous localization and mapping, abbreviated as SLAM) camera (SLAM Camera, SC), or an RGB camera for head position tracking, real-time environmental modeling, and external scene video recording, etc. However, due to the increasing complexity of the application scenarios of the head-mounted display device and the limitations of a single camera in image display functions, the head-mounted display device has poor scene adaptability, and thus it is easy to fail to meet the application requirements of users.

[0057] The present application also provides a computer program product, including a computer program. When the computer program is triggered by a processor, the steps of the image display method as described above are implemented.

[0058] The present application provides an image display method, device, head-mounted display device and readable storage medium, which are applied to a head-mounted display device.

Instead of always starting the image display mode through a single camera of the head-mounted display device. Therefore, it overcomes the technical defect that due to the increasing complexity of the application scenarios of the head-mounted display device and the limitations of a single camera in image display functions, the head-mounted display device has poor scene adaptability, and thus it is prone to the situation of being unable to meet the user's application requirements. Therefore, the display flexibility of the head-mounted display device is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] To make the above objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0073] Embodiment 1

[0074] First of all, it should be understood that for head-mounted display devices such as virtual reality helmets, virtual reality headsets or virtual reality glasses, they usually perform head position tracking, real-time environmental modeling and external scene video recording through a single configured camera. However, limited by the limitations of the camera in the display function, the current head-mounted display devices cannot be applied in many fields, such as traditional Chinese medicine physiotherapy, sports rehabilitation, health check-up and major disease screening, etc. Especially in the face of more complex application requirements in future real scenarios, the current head-mounted display devices lack scene adaptability and application convenience. Therefore, the current head-mounted display devices have low display flexibility. If the display function of the device can be made more comprehensive through hardware improvement, thereby improving the applicability of the head-mounted display device in image display, the lack of richness in image display of the head-mounted display device can be changed. Therefore, there is an urgent need for a method to improve the display flexibility of the head-mounted display device.

[0075] The embodiment of this application provides an image display method, which is applied to a head-mounted display device. In Embodiment 1 of the image display method of this application, refer to Figure 1 , the image display method includes:

[0076] Step S10, when the head-mounted display device performs image display in the first display mode, obtain a display switching instruction triggered for the head-mounted display device;

[0077] Step S20, determine the corresponding second display mode according to the display switching instruction;

[0078] Step S30, control the head-mounted display device to perform image display in the second display mode, where the first display mode and the second display mode are started by different cameras on the head-mounted display device.

[0079] In this embodiment, it should be noted that although Figure 1A logical order is shown. However, in some cases, the steps shown or described can be triggered in an order different from that here. The image display method is applied to a head-mounted display device, which can specifically be an AR glasses or a VR glasses, etc. The head-mounted display device is provided with a near-eye imaging system, which can specifically include different cameras, an electronic computing processor, a conversion interface, a power management integrated circuit, a load switch, an optical display module, and an IMU (Inertial Measurement Unit), etc. Among them, different cameras can control the activation of different display modes. The cameras can specifically be a SLAM camera, an RGB camera, an infrared thermal imaging camera, etc. The number of cameras set on the head-mounted display device can specifically be two or more. For example, in an implementable manner, assuming that the camera carried by the head-mounted display device itself is an RGB camera, an infrared sensor unit and a corresponding processor can be newly added to the hardware configuration of the head-mounted display device. Among them, for the specific installation position of the newly added infrared sensor unit on the head-mounted display device, the embodiments of the present application do not make specific limitations. For example, the RGB camera can be installed at the middle position of the head-mounted display device, while the infrared sensor camera is installed at the upper middle position of the head-mounted display device. For the installation relationship between the newly added infrared sensor unit and the head-mounted display device, the embodiments of the present application also do not make specific limitations. For example, the infrared sensor camera can be fixedly installed on the head-mounted display device or can be flexibly installed on the head-mounted display device in a detachable manner.

[0080] In addition, it should be noted that the first display mode and the second display mode are different display modes. Among them, the first display mode is used to represent the display mode triggered by the first camera on the head-mounted display device, and the second display mode is used to represent the display mode triggered by the second camera on the head-mounted display device. The first camera and the second camera are different cameras installed on the head-mounted display device, which are used to assist the head-mounted display device to realize different functions. For example, in an implementable manner, assuming that the first camera is a SLAM camera and the second camera is an infrared thermal imaging camera, and the target object is the user, then the SLAM camera is used to realize the virtual imaging display of the external features of the user, such as the environment where the user is located and the contour of the user, etc., that is, display functions such as head position tracking, real-time environment modeling, and external scene video recording. The infrared thermal imaging camera is used to realize the virtual imaging display of the internal features of the user, such as displaying the thermal distribution image generated by the change of the user's body temperature, that is, sports rehabilitation, traditional Chinese medicine physiotherapy, and health check-up, etc. The first display mode can specifically be the default display mode of the head-mounted display device or can also be the selected display mode that meets the user's usage requirements at the current time step.

[0081] Additionally, it should be noted that the display switching instruction is used to instruct the head-mounted display device to switch the display mode, which can be specifically triggered by a display operation performed by the user on the display operation device. Here, the display operation device can specifically be a handle or a finger ring, etc., and the display operation can specifically be a sliding operation or a pressing operation, etc. The head-mounted display device and the display operation device are communicatively connected. For example, in an implementable manner, assume that the head-mounted display device is an AR glasses and the display operation device is a handle. After the user presses the "switch" button on the handle, the head-mounted display device generates a display switching instruction. Then, the head-mounted display device can determine a second display mode that meets the user's needs according to the display switching instruction. Here, there is no specific limitation on the correspondence between the user and the head-mounted display device. For example, the user who performs the pressing operation on the display operation device and the user wearing the head-mounted display device can be the same user or different users. The head-mounted display device can be worn by the user or placed at a specified position.

[0082] Additionally, it should be noted that after the head-mounted display device switches the display mode, the head-mounted display device can directly convert the data and play and display the real-time image through the corresponding display unit. Here, the display unit can specifically be a waveguide lens or a free-form surface lens, etc., so that there is no need to process and play the data through an additional playback device such as a PC or a mobile phone. When the head-mounted display device displays an image in the first display mode or the second display mode, it can be executed based on the control instruction issued by the processing module of the head-mounted display device.

[0083] As an example, steps S10 to S30 include: when the head-mounted display device displays an image in the default display mode, obtaining a display switching instruction for the head-mounted display device input by the user through the display operation device; using the display switching instruction as an index, querying in a preset display mode table for a second display mode that meets the user's display needs. Here, at least one preset display mode that depends on the camera set on the head-mounted display device to start is stored in the preset display mode table, and there may be a mapping relationship between the preset display mode and the mode identifier in the display switching instruction. For example, assume that the mode identifier is "1", which indicates that the second display mode is the mode started by the infrared thermal imaging camera; assume that the mode identifier is "0", which indicates that the second display mode is the mode started by the RGB camera; obtaining a control instruction, and according to the control instruction, controlling the head-mounted display device to display an image in the second display mode, where the first display mode and the second display mode are started by different cameras on the head-mounted display device.

[0084] In an implementable manner, assume that the head-mounted display device is an AR glasses, on which a DOF camera module and an RGB camera module are deployed. To improve the scene adaptability of the AR glasses and enhance the display flexibility of the AR glasses, an infrared thermal imaging camera module can be added to the AR glasses, and relevant algorithms can be added to achieve the switching of the display mode of the virtual image presented via the head-mounted display device. Among them, the infrared thermal imaging camera module can be flexibly installed on the AR glasses. Refer to Figure 2 , Figure 2 FIG. Figure 2 is a schematic diagram of the AR glasses with a detachable infrared thermal imaging camera module installed. Among them, 11 is the installation position of the infrared thermal imaging camera module, 12 is the ranging camera module with six degrees of freedom on the right side, 13 is the right AR lens, 14 is the RGB camera module, 15 is the ranging camera module with six degrees of freedom on the left side, and 16 is the left AR lens. Among them, the infrared thermal imaging camera module includes an infrared sensor unit and a corresponding processor, which together serve as accessories of the AR glasses. Specifically, the infrared sensor unit can be based on requirements and installed on the type-C interface of the entire AR glasses, and the corresponding processor can be integrated into the circuit of the AR glasses itself, so as to be used as an integrated device. Among them, the above-mentioned software and hardware can be regarded as an image display system for supporting the implementation of the image display method. Refer to Figure 3 , Figure 3Schematic diagram of the structure of an image display system. Specifically, the image display system may include U1: AP (Application Processor, application chip), U2: interface conversion IC, U3: charger, U4: PMIC1 (Power Management IC, integrated power management chip 1), U5: loadswitch, power switch, U6: PMIC2, U7: CPLD (Complex Programmable Logic Device, digital integrated circuit), U8: 2 ranging camera modules with six degrees of freedom in all directions, U9: 1 RGB camera module, one IMU (Inertial Measurement Unit, inertial sensor) unit, left optical display module, right optical display module, left speaker module, right speaker module, infrared thermal imaging camera module, and battery pack unit, etc. Among them, the AP includes radio frequency and wireless related modules, etc. Its radio frequency and antenna parts are responsible for wireless communication of WIFI / BT with mobile phones or PCs. The mobile phone can transmit video files, audio files, etc. to the AR glasses through WIFI or BT (BitTorrent, source file) for playback. The AP is responsible for image processing of the entire display module, encoding and decoding of the camera module, 6DOF algorithm processing, and processing of audio uplink and downlink algorithms; the charging management logic module is responsible for charge and discharge management of the internal battery module of the system; the PMIC1 system power module is responsible for providing power to the memory RAM, memory, radio frequency module, and wireless communication module of the entire AP control end; the Load switch power switching module is responsible for controlling the U6 PMIC2 power chip to provide power to the interface conversion IC and various Camera modules. Its enable terminal is controlled by the AP processor. In the low-power mode, power consumption can be reduced by turning off the power of peripheral camera and other modules; the PMIC2 integrated power chip is responsible for providing multiple power supplies to the U2 interface conversion chip and each Camera module; the interface conversion IC is responsible for converting the signals generated by the DOF camera module with six degrees of freedom in all directions, RGB Camera module, and CPLD into USB communication interface data and giving it to the AP in real time; the CPLD is responsible for image processing of the data collected by the infrared thermal imaging senor and generating MIPI format data to the U2 interface chip; the left and right speaker modules are responsible for audio playback of the corresponding temple; the left and right display modules are responsible for displaying the AR virtual optical image, RGB camera, or infrared thermal imaging data in the real scene in real time.

[0085] When the image is displayed in the first display mode on the head-mounted display device according to an embodiment of the present application, the second display mode that meets the user's needs is determined through a display switching instruction triggered by the user on the display operation device. Finally, the head-mounted display device is controlled to display the image in the second display mode through a control instruction, so as to achieve the purpose of completing the display mode switching on the head-mounted display device and displaying the image in the display mode that meets the user's needs, thereby improving the scene adaptability of the head-mounted display device. Instead of always displaying the image in the display mode started by a single camera. Therefore, it overcomes the technical defect that due to the increasing complexity of the application scenarios of the head-mounted display device and the limitations of a single camera in the image display function, the scene adaptability of the head-mounted display device is poor, and thus it is easy to fail to meet the user's application requirements. Therefore, the display flexibility of the head-mounted display device is improved.

[0086] Among them, the head-mounted display device includes a first button and a second button. The step of obtaining a display switching instruction triggered for the head-mounted display device when the head-mounted display device displays an image in the first display mode includes:

[0087] Step A10, when the head-mounted display device is controlled to be in a preset main interface based on the first button, control the head-mounted display device to display an image in the first display mode according to a first preset operation triggered on the second button;

[0088] Step A20, generate the display switching instruction according to a second preset operation triggered on the second button.

[0089] In this embodiment, it should be noted that, in order to improve the flexibility of the head-mounted display device for adjusting the image display mode, in addition to triggering the display switching instruction through a display operation device such as a handle or a bracelet, a button can also be set on the head-mounted display device to control the image display mode. Among them, the first button and the second button are buttons set at different positions on the head-mounted display device. The first button is used to trigger the head-mounted display device to enter a preset main interface, and the second button is used to generate a display switching instruction to enable the head-mounted display device to switch between different display modes. The first button can specifically be a power button or a dedicated trigger button for the preset main interface, etc. The second button can specifically be a multifunctional button or a display mode switching button, etc. The first preset operation can specifically be a voice command operation or a touch operation. For example, in an implementable manner, assuming that the first button is a power button, after the user presses the first button, a corresponding control instruction can be generated to control the head-mounted display device to be in the preset main interface. The preset main interface is used to represent the display state before performing the preset operation on the button of the head-mounted display device, and can specifically be a state of displaying an image in the default display mode or a state of displaying the default virtual reality main interface. The head-mounted display device is controlled to display an image in the first display mode through the first preset operation triggered by the second button, and then a display switching instruction is generated based on the second preset operation. Among them, the second preset operation can specifically be a voice command operation or a touch operation, and the second preset operation and the first preset operation can be the same or different. For example, in an implementable manner, assuming that the second button is a display mode switching button, the user can trigger the completion of displaying an image in the first display mode and generate a display switching instruction by pressing the second button twice.

[0090] As an example, steps A10 to A20 include: obtaining a first key operation triggered by the user on the switch key, controlling the head-mounted display device to display a default virtual reality main interface according to the key operation, obtaining a second key operation triggered by the user on the display switch key, generating a first control instruction according to the second key operation, and controlling the head-mounted display device to perform image display in a first display mode based on the first control instruction; obtaining a third key operation triggered by the user on the display switch key, and generating the display switch instruction according to the third key operation, wherein the first key operation, the second key operation, and the third key operation can be the same or different from each other. By setting key operations on the head-mounted display device, the head-mounted display device can be directly controlled to be in a preset main interface through the first key on the head-mounted display device, and a preset key operation can be executed through the second key, so as to achieve the purpose of controlling the head-mounted display device to perform image display in a first display mode and triggering the generation of a display switch instruction for switching the image display mode. Instead of relying on the information interaction between the display operation device and the head-mounted display device to control the display mode of the head-mounted display device. Therefore, while improving the display flexibility of the head-mounted display device, the scene adaptability of the head-mounted display device and the flexibility of adjusting the image display mode are improved.

[0091] In an implementable manner, assume that the head-mounted display device is an AR glasses, assume that the first key is a power key, and the second key is a dedicated display switch key. When the user long-presses the power key, the AR glasses start and then enter the default virtual reality main interface. When the user short-presses the display switch key, the AR glasses will enter the RGB camera recording and display it on the optical module in real time. At the same time, the video data will be stored in the memory unit of the AP. When the user short-presses the display switch key again, the AR glasses will switch to the infrared thermal imaging camera recording and display the image on the optical module in real time.

[0092] Wherein, the image display method further includes:

[0093] Step B10, controlling the head-mounted display device to be in the preset main interface according to a third preset operation triggered on the first key; or,

[0094] Step B20, controlling the head-mounted display device to be in the preset main interface according to a fourth preset operation triggered on the second key.

[0095] In this embodiment, it should be noted that the third preset operation can be considered as the first button operation. When the head-mounted display device is not yet started, the head-mounted display device can be controlled to enter the preset main interface through the third preset operation. When the head-mounted display device is displaying in the display mode that the head-mounted display device has, it can also return to the preset main interface through the fourth preset operation triggered on the second button. Among them, the third preset operation and the fourth preset operation can be the same or different. For example, in an implementable manner, assume that the first button is the power button and the second button is the multifunctional button. After the user long-presses the first button, the head-mounted display device displays the preset main interface. When the head-mounted display device switches from the first display mode to the second display mode for image display, by short-pressing the multifunctional button again by the user, the display state of the head-mounted display device can be switched back to the virtual reality main interface.

[0096] As an example, steps B10 to B20 include: when it is detected that the user long-presses the first button, controlling the head-mounted display device to be in the preset main interface; or,

[0097] After controlling the head-mounted display device to perform image display in the second display mode, obtaining a switching instruction triggered by the user short-pressing the second button, and controlling the head-mounted display device to switch from the second display mode to the preset main interface according to the switching instruction. Since the head-mounted display device can be controlled to be in the preset main interface through both the first button and the second button, the technical defect of controlling the head-mounted display device to be in the preset main interface by a single button can be avoided. Therefore, the control limitation of the head-mounted display device for controlling the preset main interface is reduced.

[0098] Among them, after the step of controlling the head-mounted display device to be in the preset main interface, the image display method further includes:

[0099] Step C10, detecting whether a fifth preset operation is triggered on the first button and / or the second button within a preset time period;

[0100] Step C20, if so, controlling the head-mounted display device to perform image display according to the display instruction corresponding to the fifth preset operation;

[0101] Step C30, if not, controlling the head-mounted display device to switch from the preset main interface to the standby state.

[0102] In this embodiment, it should be noted that in some application scenarios, after the head-mounted display device is started, the user does not necessarily perform the relevant operations for display switching. Therefore, considering multiple aspects such as increasing battery life and reducing standby power consumption, after no operation by the user on the first button and the second button is detected for a long time, the display state of the head-mounted display device can be switched. Among them, the preset time period is specifically set by the user according to requirements. The fifth preset operation may be the same as or different from the above-mentioned preset operation. The standby state is used to represent the low-power state, which can specifically be screen-off, semi-screen-off, or reducing the display parameters of the head-mounted display device for display, etc. If the fifth preset operation is detected, the image can be displayed according to the button where the fifth preset operation is performed and the corresponding display requirements. For example, in an implementable manner, if the fifth preset operation is a long press operation on the first button, the head-mounted display device is controlled to shut down. If the fifth preset operation is a short press operation on the second button, the head-mounted display device can be controlled to enter the corresponding display mode for image display.

[0103] As an example, steps C10 to C30 include: detecting whether a fifth preset operation is triggered on the first button and / or the second button within a preset time period; if the fifth preset operation is triggered on the first button or the second button within the preset time period, image display is performed based on the display instruction corresponding to the fifth preset operation, where the display instruction can specifically be a shutdown instruction or a display mode switching instruction, etc.; if the fifth preset operation is not triggered on both the first button and the second button within the preset time period, the head-mounted display device is actively controlled to be switched from the preset main interface to the standby state.

[0104] Among them, after the step of controlling the head-mounted display device to be switched from the preset main interface to the standby state, the image display method further includes:

[0105] Step D10, detecting whether the operation duration of the sixth preset operation triggered on the first button is greater than the preset operation duration threshold;

[0106] Step D20, if so, controlling the head-mounted display device to be switched from the standby state to the shutdown state;

[0107] Step D30, if not, controlling the head-mounted display device to be switched from the standby state to the preset main interface.

[0108] In this embodiment, it should be noted that after the head-mounted display device enters the standby state, different display controls can still be performed based on the operation duration of the sixth preset operation triggered by the user on the first button. The preset operation duration threshold can be specifically set by the user according to requirements. For example, in an implementable manner, assuming that the first button is the power button, after the head-mounted display device enters the standby screen-off state, short-pressing the power button can re-enter the working state, that is, enter the preset main interface, and long-pressing the power button can enter the shutdown state.

[0109] As an example, steps D10 to D30 include: detecting whether the operation duration of the sixth preset operation triggered on the first button is greater than the preset operation duration threshold; if it is detected that the operation duration of the sixth preset operation triggered on the first button is greater than the preset operation duration threshold, then control the head-mounted display device to switch from the standby state to the shutdown state; if it is detected that the operation duration of the sixth preset operation triggered on the first button is less than or equal to the preset operation duration threshold, then control the head-mounted display device to switch from the standby state to the preset main interface, where the sixth preset operation can be the same as or different from the above-mentioned preset operation. By detecting the operation duration of the sixth preset operation performed by the user on the first button, different control operations can be selectively performed on the head-mounted display device based on the different operation durations. Therefore, the control flexibility of the head-mounted display device by button control is improved.

[0110] In an implementable manner, assume that the first display mode is the RGB display mode, the second display mode is the infrared thermal imaging display mode, the first button is the power-on button, and the second button is the multifunctional button. Refer to Figure 4 , Figure 4 As a flowchart showing the implementation of an AR glasses with infrared thermal imaging display mode and RGB display mode, after pressing the power-on button, the AR glasses start. At this time, the AR glasses default to enter the AR virtual reality main interface. If no user performs a preset operation on any button within 15 seconds, the AR glasses enter the screen-off state. If the user short-presses the power-on button, the AR glasses default to return to the AR virtual reality main interface. If the user long-presses the power-on button, the AR glasses directly shut down. If the user short-presses the multifunctional button, the AR glasses enter the RGB camera display mode, and the RGB camera starts recording and storing. If the user short-presses the multifunctional button again, the AR glasses enter the infrared thermal imaging display mode, and the infrared thermal imaging module starts recording and storing. If the user short-presses the multifunctional button again thereafter, the AR glasses default to return to the AR virtual reality main interface.

[0111] Among them, obtaining the display switching instruction triggered for the head-mounted display device includes:

[0112] Step E10, obtain the time information and weather information of the environment where the head-mounted display device is located;

[0113] Step E20, detect the display environment of the head-mounted display device according to the time information and the weather information;

[0114] Step E30, when it is detected that the display environment meets the first preset switching condition, generate the display switching instruction for the head-mounted display device.

[0115] In this embodiment, it should be noted that due to the different adaptabilities of different camera modules in different scenarios. For example, an infrared thermal imaging camera mainly focuses on photographing the internal characteristics of a target object, such as internal temperature, etc., while an RGB camera focuses on photographing the external characteristics of a target object, such as the environment and contour, etc. At the same time, since different camera modules have their own advantages and disadvantages, a display switching instruction can be automatically generated in different display environments to complete the switching of the display mode, so that the display environment and the display mode are matched. Among them, the time information is used to represent the time situation, and the weather information is used to represent the weather situation. For example, in an implementable manner, the time information can specifically be "daytime" or "night", etc., and the weather information can specifically be "rainy day", "sunny day" or "foggy day", etc. The visibility situation in the current display environment can be comprehensively evaluated through the time information and the weather information. When the visibility is insufficient, an infrared thermal imaging camera can be used for image display, and when the visibility is sufficient, an RGB camera can be used for image display. Among them, detecting the display environment of the head-mounted display device can specifically be done through a pre-trained visibility prediction model. The first preset switching condition can specifically be set by the user according to the display requirements, and can specifically be a specific value or a text identifier, etc.

[0116] As an example, steps E10 to E30 include: obtaining the time information and weather information of the environment where the head-mounted display device is located; extracting features from the time information and the weather information through a preset visibility prediction model to obtain time features and weather features; predicting the visibility of the display environment where the head-mounted display device is currently located according to the time features and the weather features; when it is detected that the visibility is greater than a preset visibility threshold, generating the display switching instruction for the head-mounted display device. Since when the display environment changes too much, relying on the current camera module cannot meet the user's display requirements, a display switching instruction is automatically generated to complete the switching of different display modes of the head-mounted display device, so that the image display is not affected by external light and can support the environmental recognition requirements at night or in rainy and foggy conditions. Therefore, it lays a foundation for improving the scene adaptability of the head-mounted display device.

[0117] The embodiments of the present application provide an image display method, apparatus, head-mounted display device, and readable storage medium, which are applied to the head-mounted display device. That is, when the head-mounted display device displays an image in the first display mode, a display switching instruction triggered for the head-mounted display device is obtained; according to the display switching instruction, a corresponding second display mode is determined; and the head-mounted display device is controlled to display the image in the second display mode, where the first display mode and the second display mode are started by different cameras on the head-mounted display device.

[0118] When the head-mounted display device of the embodiments of the present application displays an image, first, when displaying the image in the first display mode, it continuously detects whether there is a display switching instruction triggered for the head-mounted display device, and obtains the display switching instruction when there is a display switching instruction. Then, according to the display switching instruction, a corresponding second display mode is determined. Finally, the head-mounted display device is controlled to display the image in the second display mode, so as to achieve the purpose of triggering the head-mounted display device to switch the image display mode through the display switching instruction and displaying the image in different display modes.

[0119] Since the first display mode and the second display mode are started by different cameras on the head-mounted display device, the head-mounted display device can display the image by applying the image display functions of different cameras, thereby achieving the purpose of improving the scene adaptability of the head-mounted display device.

[0120] Based on this, when the head-mounted display device of the embodiments of the present application displays an image, through the display switching instruction triggered for the head-mounted display device, the purpose of switching the display mode on the head-mounted display device for image display is achieved, so that the head-mounted display device can be applied to more complex application scenarios. Instead of always starting the image display mode through a single camera of the head-mounted display device. Therefore, it overcomes the technical defect that due to the increasing complexity of the application scenarios of the head-mounted display device and the limitations of a single camera in image display functions, the head-mounted display device has poor scene adaptability, and thus it is easy to fail to meet the application requirements of users. Therefore, the display flexibility of the head-mounted display device is improved.

[0121] Embodiment 2

[0122] Further, referring to Figure 5 , in another embodiment of the present application, the content that is the same as or similar to that in the above Embodiment 1 can be referred to the above introduction and will not be described in detail hereinafter. On this basis, the obtaining of the display switching instruction triggered for the head-mounted display device includes:

[0123] Step F10, obtaining the display parameters corresponding to the target object displayed by the head-mounted display device in the first display mode;

[0124] Step F20: When it is detected that the display parameter meets the second preset switching condition, generate the display switching instruction for the head-mounted display device.

[0125] In this embodiment, it should be noted that due to the different characteristics of different camera modules, in addition to the differential image display capabilities in the display environment, there are also differential image display capabilities in the range and distance of the object being photographed by different camera modules. By deploying a specific camera module on the existing head-mounted display device, the head-mounted display device can be made to have the image display capabilities required for a large field of view or long-distance measurement. Among them, the target object is used to represent the actual object for which the head-mounted display device performs display, and specifically can be a person or an object. The display parameter is used to represent the image display capabilities, and specifically can be the display distance between the head-mounted display device and the target object, or the display range of the head-mounted display device. For example, in an implementable manner, assume that the display parameter is the display distance between the head-mounted display device and the target object. When the display distance is greater than the preset display distance, that is, when the head-mounted display device switches from a small field of view display to a large field of view display, a display switching instruction can be triggered to be generated. The second preset switching condition and the first preset switching condition are different preset switching conditions, and specifically can be specific numerical values, or text identifiers, etc.

[0126] As an example, steps F10 to F20 include: obtaining the display distance between the head-mounted display device and the target object when the head-mounted display device is in the first display mode; when it is detected that the display distance is greater than the preset display distance threshold, generating the display switching instruction for the head-mounted display device.

[0127] As another example, steps F10 to F20 include: obtaining the display range of the head-mounted display device when the head-mounted display device is in the first display mode; when it is detected that the range is less than the preset display range threshold, generating the display switching instruction for the head-mounted display device.

[0128] An embodiment of the present application provides a method for generating a display switching instruction, that is, obtaining display parameters corresponding to a target object displayed by the head-mounted display device in the first display mode; when it is detected that the display parameters meet a second preset switching condition, generating the display switching instruction for the head-mounted display device. When generating the display switching instruction in the embodiment of the present application, by obtaining the display parameters of the target object displayed by the head-mounted display device in the first display mode and based on the relationship between the display parameters and the second preset switching condition, the display switching instruction is automatically generated for the head-mounted display device, that is, when the image display scene requirements cannot be met when displaying an image in the first display mode, by automatically generating the display switching instruction for subsequent switching to obtain a second display mode that meets the image display scene requirements. Therefore, it lays a foundation for improving the scene adaptability of the head-mounted display device.
