Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

It should be noted that, for the sake of brevity, this description does not exhaust all alternative embodiments, and it should be understood by those skilled in the art after reading this description that any combination of features may constitute an alternative embodiment as long as the features are not mutually inconsistent. The following examples are described in detail.

VR technology has been developed in recent years, wherein video see-through technology is gradually starting to be applied in order to solve the problem that the surrounding environment cannot be seen when wearing VR devices. Specifically, the video perspective technology is to add a color camera to a VR device, so that when a video perspective function is turned on, an image captured by the color camera is transmitted to a screen of the VR device, so that a user can observe the surrounding environment.

When two color cameras are assembled, parallax can be formed by utilizing image difference captured by the left camera and the right camera, so that a user can judge the distance between the two color cameras and surrounding objects. Because different users 'interpupillary distance is different, and the assembly interval of two color camera is fixed, consequently, different users when wearing VR equipment, can appear great deviation to the distance judgement of object around, influence user's experience and feel.

Currently, on VR products, video perspective technology is just beginning to be applied. Generally, in order to obtain a user experience close to the actual situation, two video perspective color cameras are assembled on a VR product, and the positions where the two cameras are assembled need to be right opposite to the centers of two VR lenses. The assembly distance between the two cameras is basically determined by the interpupillary distance of human eyes, and for example, the assembly distance can be 58mm to 72mm. However, this method causes the camera mounting position to be limited, and since the pupil distances of different users are also different, when different users use VR products to perform video perspective, there may be a case where the deviation is large in the distance determination of an object observed by the camera.

The application provides an image adjusting method, device, equipment and medium based on a virtual reality technology, and aims to solve the technical problems in the prior art.

The following describes the technical solutions of the present application and how to solve the above technical problems in detail with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic flowchart of an image adjustment method based on a virtual reality technology, which is provided in an embodiment of the present application, and is applied to a virtual reality device, where the virtual reality device includes a video perspective camera, and the method can be executed by an image adjustment apparatus based on a virtual reality technology. As shown in fig. 1, the method comprises the steps of:

s101, acquiring an image to be adjusted based on a video perspective camera on the virtual reality equipment.

Illustratively, at least two video perspective cameras, which may be color cameras, may be installed on the VR device. In the embodiment of the application, because the image of the surrounding environment displayed by the VR device can be adjusted, the assembly position of the video perspective camera on the VR device is not limited. The video perspective camera can be installed on VR equipment just to the position at the center of VR lens, also can install the both sides at VR equipment. Fig. 2 is a schematic diagram of a user wearing a VR device. In fig. 2, there are two video perspective cameras in the front of the VR device, the positions of the video perspective cameras are right opposite to the eyes of the user, and the eyes of the user are close to the center of the VR lens, that is, the positions of the video perspective cameras are right opposite to the center of the VR lens. Fig. 3 is a schematic diagram of video perspective cameras on two sides of a VR device. In fig. 3, there are two video perspective cameras, one on each side of the VR lens, not aligned with the center of the VR lens.

When the user wears the VR equipment, the video perspective camera on the VR equipment can collect the images around the environment where the user is located, and can transmit the collected images to the screen of the VR equipment. And determining the acquired image as an image to be adjusted, and allowing a user to see the image to be adjusted through VR equipment.

When two video perspective cameras on the VR device capture images, the images are different, so that parallax is formed. Fig. 4 is a schematic diagram of an actual scene of an environment in which a user is located. A table lamp, a display and a, b, c and d four books exist in the actual scene of the environment where the user is located. Fig. 5 is a schematic diagram of an image to be adjusted displayed by the VR device. The VR equipment comprises a left display screen and a right display screen, images to be adjusted, which are collected by the video perspective camera on the left side, are sent to the left display screen, and images to be adjusted, which are collected by the video perspective camera on the right side, are sent to the right display screen. Due to the fact that the assembly positions of the cameras are different, the video perspective camera positioned on the left side of the VR equipment collects a plurality of images of a left scene, and a plurality of images of a right scene are collected; the video perspective camera positioned on the right side of the VR device collects more images of the right scene and less images of the left scene.

S102, determining an adjusting range corresponding to the pupil distance information of the user according to the pre-stored pupil distance information of the user and the association relation between the preset pupil distance information and the adjusting range, wherein the adjusting range is a target adjusting range.

Illustratively, before using the VR device, the user may input his/her own pupil distance information in advance, which is the distance between the centers of the pupils of both eyes of the user. And if the difference value between different pieces of interpupillary distance information is within a preset difference value threshold value, the different pieces of interpupillary distance information can correspond to the same adjustment range. That is, if there is only a slight difference between different pupil distance information, there is no large difference between corresponding adjustment ranges, and thus, the user does not need to input an accurate value of the pupil distance. For example, the association relationship between the numerical range of different pupil distance information and the adjustment range may be stored in advance, the user may input pupil distance information of 60mm, and the user's actual pupil distance information may be 61mm, and the adjustment range corresponding to 60mm and the adjustment range corresponding to 61mm may be the same.

The adjustment range refers to a distance range in which a user can zoom in or out on an image to be adjusted when adjusting the perception distance, or a range of a scaling scale. And according to the pupil distance information input by the user, a corresponding target adjustment range can be obtained when the user adjusts. That is, when the user adjusts the sensing distance, the user only needs to adjust within the limited target adjustment range, so that the adjustment range of the user is effectively reduced, and the adjustment efficiency and accuracy are improved.

S103, adjusting the image to be adjusted according to image perception distance adjusting operation sent by a user based on the target adjusting range to obtain an adjusted image which is a target image; the perceived distance is used for representing the distance between objects which are perceived by a user through the human eyes and correspond to the viewed image.

Illustratively, after seeing an image to be adjusted, a user forms parallax by using the difference between images captured by the left and right cameras, so that the distance between the user and an object corresponding to the image to be adjusted can be judged as a perceived distance. The user can adjust the perception distance of the image to be adjusted according to the actual distance between the user and each object in the environment where the user is located. The perceived distance may refer to a distance between objects corresponding to the viewed image, which is perceived by the user through human eyes.

The user can take off VR equipment, compares actual distance and perception distance at any time. For the convenience of comparison between the image perception distance and the actual distance in the calibration process of a user, when the user takes off the VR equipment in the calibration process, the VR equipment can not enter a sleep state and still keeps in a distance calibration mode. The distance calibration mode can be a mode for calibrating the perception distance, and a user can start the distance calibration mode when wearing the VR device, so that an image to be adjusted is obtained, and the perception distance of the image to be adjusted is adjusted within a target adjustment range.

An operation control for adjusting the image sensing distance may be arranged on the VR device, for example, the operation control may be an operation knob, the operation for adjusting the image sensing distance may be a rotation operation performed on the operation knob, and rotating the operation knob to the left may reduce a sensing distance of the user to the image to be adjusted, that is, the image to be adjusted seen by the user is perceptually closer to the user; rotating the operation knob to the right may be to increase a perceived distance of the user to the image to be adjusted, i.e., to make the image to be adjusted seen by the user perceptually farther from the user. The user can remove the VR equipment at any time in the process of executing the image perception distance adjustment operation, and the image to be adjusted is compared with the real picture seen by the user in the actual scene, so that the perception distance of the image to be adjusted by the user is consistent with the actual distance of the actual scene. When the user determines that the sensing distance is consistent with the actual distance, the image sensing distance adjustment operation can be stopped. And after the image perception distance adjustment operation is finished, the image to be adjusted is adjusted, and the adjusted image is determined as the target image. At this time, the distance between the user and the actual object, which is seen by the user without wearing the VR device, is consistent with the distance between the user and the object, which is seen by the VR device.

When the image to be adjusted is adjusted, the images of the left and right display screens are adjusted at the same time, for example, if the user wants to zoom in at the sensing distance, the images to be adjusted of the left and right display screens are simultaneously zoomed in at the same distance. That is, the sizes of the objects viewed by the user through the left and right display screens are identical.

Fig. 6 is a schematic diagram of an image to be adjusted for approximating a sensing distance in the embodiment of the present application. As can be seen from fig. 6 and 5, the image in fig. 6 is closer than the perceived distance of the image in fig. 5, and the perceived distances of both the left and right display screens are pushed closer. In the process of calibrating the perception distance of the image, if the user determines that the actual distance is closer than the displayed perception distance, the VR device may be controlled to zoom in on the picture. Comparing fig. 6 and 5, it can be seen that the picture is pushed forward, the image becomes larger, and the desktop area displayed on the screen also becomes smaller. The user can feel that the distance of the surrounding scenery is reduced, thereby the distance calibration function is realized.

Fig. 7 is a schematic diagram of an image to be adjusted of a zoom-out sensing distance in an embodiment of the present application. As can be seen from fig. 7 and 5, the image in fig. 7 is farther than the perceived distance of the image in fig. 5, and the perceived distances of both the left and right display screens are pulled far. In the process of calibrating the perceived distance of the image, if the user determines that the actual distance is longer than the displayed perceived distance, the VR device may be controlled to zoom out on the picture. Comparing fig. 7 and fig. 5, it can be seen that the picture is zoomed out, the image becomes smaller, and the desktop area displayed on the screen becomes larger. The user can feel that the distance of the surrounding scenery is increased, and the distance calibration function is achieved.

S104, determining a preset adjustment identifier corresponding to the image perception distance adjustment operation, and storing the adjustment identifier; the adjustment identifier is used for indicating the adjustment of the perception distance of the image to be adjusted in the image perception distance adjustment operation.

Illustratively, adjustment marks corresponding to different image perception distance adjustment operations are preset, for example, an adjustment mark corresponding to an approach of a perception distance of an image to be adjusted to 1% is set to be 01; and marking the adjustment mark corresponding to the fact that the perception distance of the image to be adjusted is increased by 1% as-01. The zooming-in percentage and the zooming-out percentage may refer to a scaling ratio of the image to be adjusted, the zooming-in percentage may refer to an enlargement of the image to be adjusted, and the zooming-out percentage may refer to a reduction of the image to be adjusted. For example, a zoom-in of 1% may refer to a zoom of the image to be adjusted to be 1% enlarged, with objects in the image to be adjusted being visually closer to the user. For another example, if the image sensing distance adjustment operation is to rotate a knob, it may be determined that the adjustment flag corresponding to one frame of leftward rotation is 01; the adjustment mark corresponding to rotating one grid to the right is-01. And determining the image perception distance adjustment operation of the obtained target image, and determining a corresponding adjustment identifier according to the image perception distance adjustment operation. The adjustment identifier may be used to indicate that when the user performs an image sensing distance adjustment operation on the image to be adjusted, the adjustment value of the sensing distance of the image to be adjusted may be an adjustment value of the sensing distance, for example, the adjustment value may be a push-up value of 1% or a pull-up value of 1%.

If the user adjusts the perception distance of the image to be adjusted, it indicates that the installation position of the video perspective camera on the VR device is not suitable for the interpupillary distance of the user, that is, the user needs to adjust the image to be adjusted when using the VR device. After the target image is obtained, the adjustment identification of the image perception distance adjustment operation corresponding to the target image is recorded, the adjustment identification is stored, the adjustment of the perception distance of the collected image is automatically carried out according to the adjustment identification when the user uses the VR equipment subsequently, and the use experience of the user is improved.

In this embodiment, after storing the adjustment identifier, the method further includes: responding to a use instruction of the virtual reality equipment, and acquiring a stored adjustment identifier; acquiring a current image acquired by a video perspective camera on virtual reality equipment; and adjusting the perception distance of the current image according to the adjustment identifier, and displaying the adjusted image to a user.

Specifically, after the adjustment identifier corresponding to the target image is stored in the VR device, the user can use the VR device at any time. When the user uses the VR device again, the VR device may obtain the stored adjustment identifier in response to a use instruction issued by the user to the VR device. For example, the obtained adjustment flag is 01.

The VR equipment can acquire an image of the current environment of the user in real time through the video perspective camera to serve as the current image. And determining the adjustment operation needed to be performed on the current image according to the acquired adjustment identifier. Each adjustment marker corresponds to a unique adjustment operation, for example, the adjustment operation indicated by the adjustment marker 01 is to approximate the acquired image to 1%. Namely, the perception distance of the current image is adjusted according to the adjustment identifier, and the adjusted image is displayed to the user, so that the perception distance of the image seen by the user can be consistent with the actual distance seen by the user without wearing the VR device.

The beneficial effect who sets up like this lies in, write in the adjustment sign in the memory cell of VR equipment to when the user opened video perspective function next time, call this adjustment sign, adjust the current image of gathering automatically, thereby make the user obtain in real time with the image of the perception distance that actual distance is close, promote user's use and experience.

The current assembly position of camera is fixed, though installed in VR lens place area, because different users' interpupillary distance is different, can be different to the perception of distance, does not pass through the calibration, still has the inaccurate problem of distance sense. In addition, in order to make the image obtained by the color camera as much as possible to be directly observed by human eyes, the color camera is basically assembled in the area corresponding to the VR lens, so that the appearance design of the product is limited and the development difficulty is increased. In the embodiment of the application, the assembly position of the color camera for video perspective has great flexibility. After the user adopts this application embodiment to calibrate, can be more accurate to the sense of distance to the external object who observes through video perspective technique, and need not all adjust when wearing at every turn, reduce user operation.

According to the image adjusting method based on the virtual reality technology, the scene image around the user is obtained through the camera on the VR device and serves as the image to be adjusted. The user may perform an image perceived distance adjustment operation, and adjust the perceived distance of the image to be adjusted within the target adjustment range, for example, the perceived distance of the image to be adjusted may be pushed or pulled. The target adjustment ranges corresponding to different users are different, the adjustment range of the user is narrowed, and the adjustment efficiency of the user is improved. And after the adjustment is finished, obtaining a target image, and enabling the perception distance of the user to the target image to be consistent with the actual distance of the user to the article. Different adjustment operations can correspond to different adjustment identifications, the adjustment identification of the image perception distance adjustment operation corresponding to the target image is determined, and the adjustment identification is stored for facilitating subsequent use. The problem of among the prior art, because the assembly interval of camera is fixed, and can't adjust the image of surrounding environment is solved, improve the flexibility of adjusting the image. Through adjustment perception distance, the scenery distance that makes the user see through VR equipment is unanimous with the scenery distance that actually sees, and the user of being convenient for when wearing VR equipment accurately takes and uses article around, promotes the user and experiences the use of VR equipment.

Fig. 8 is a schematic flowchart of an image adjustment method based on a virtual reality technology according to an embodiment of the present application, which is an alternative embodiment based on the foregoing embodiment.

In this embodiment, according to the image sensing distance adjustment operation sent by the user, the image to be adjusted is adjusted to obtain an adjusted image, which is a target image and can be subdivided into: in response to a picture zooming-in instruction or a picture zooming-out instruction made by a user through a handle of the virtual reality equipment, zooming in or zooming out is carried out on the perception distance of the image to be adjusted; the image zooming-out instruction is used for indicating that the perception distance of the image to be adjusted is increased; and determining the image picture after zooming in or zooming out as a target image.

As shown in fig. 8, the method comprises the steps of:

s801, acquiring an image to be adjusted based on a video perspective camera on the virtual reality device.

For example, this step may refer to step S101 described above, and is not described again.

S802, determining an adjusting range corresponding to the pupil distance information of the user as a target adjusting range according to the pre-stored pupil distance information of the user and the association relation between the preset pupil distance information and the adjusting range.

For example, this step may refer to step S102 described above, and is not described again.

S803, based on the target adjustment range, responding to a picture zooming-in instruction or a picture zooming-out instruction made by a user through a handle of the virtual reality device, and zooming in or zooming out the perception distance of the image to be adjusted; the image zooming-out instruction is used for indicating that the perception distance of the image to be adjusted is increased.

For example, the VR device may be configured with a handle, and the user may wear the VR device on his head and hold the handle for adjustment. For example, the handle may be provided with operation keys, which may be a plus key and a minus key. Plus keys indicate increasing the perceived distance and minus keys indicate decreasing the perceived distance. The adjustment step length of the sensing distance of each time the operation key is pressed can be preset, for example, the sensing distance is increased by 1% when the plus key is pressed; every time the minus key is pressed, the sensing distance is reduced by 1%. Or, the handle can be provided with a rocker, the rocker is rocked towards the front of eyes to indicate that the sensing distance is reduced, the rocker is rocked towards the back of the body to indicate that the sensing distance is increased, the sensing distance changes by 1% after the rocker is rocked once, and the rocker is self-reset after the rocker is rocked every time. Alternatively, the handle may be provided with a knob, wherein rotating the knob counterclockwise means decreasing the perceived distance and rotating the knob clockwise means increasing the perceived distance. The joystick may be a physical joystick on the handle, or may be a virtual joystick displayed by the VR device.

The handle can be a wireless handle, can also be wired handle, can also set up on VR equipment body.

The user sends out a picture zooming-in instruction or a picture zooming-out instruction by carrying out image perception distance adjustment operation on the handle. For example, the user may press the plus key to issue a zoom-out command, or may press the minus key to issue a zoom-in command. That is, the picture zooming-in instruction may be used to indicate that the perceived distance of the image to be adjusted is decreased, and the picture zooming-out instruction may be used to indicate that the perceived distance of the image to be adjusted is increased. The handle is used for executing the image perception distance adjustment operation, so that the operation of a user can be facilitated, and the image adjustment efficiency is improved.

In this embodiment, adjusting an image to be adjusted according to an image sensing distance adjustment operation sent by a user to obtain an adjusted image, which is a target image, includes: receiving a voice control instruction sent by a user to the image to be adjusted; the voice control instruction comprises a picture zooming-in instruction and a picture zooming-out instruction; and according to the voice control instruction, carrying out zooming-in or zooming-out on the perception distance of the image to be adjusted, and determining the image picture after zooming-in or zooming-out as a target image.

Specifically, the user may control the VR device with a voice to adjust the sensing distance, and the user sends a voice control instruction, where the voice control instruction may include a frame zoom-in instruction and a frame zoom-out instruction. For example, if the screen zoom-in instruction that the user can make a voice is "zoom-in 1%", the VR device zooms in the perceived distance of the screen to be adjusted by 1% after receiving the voice made by the user.

And the VR equipment adjusts the perception distance of the image to be adjusted according to the voice control instruction of the user. The user can check the adjusted image to be adjusted in real time, and if the user confirms that the adjustment is completed, the adjusted image to be adjusted can be determined as the target image. That is, the image screen after zooming in or out is determined as the target image.

The beneficial effect who sets up like this lies in, the user need not manual operation, only need send the pronunciation can, reduce user operation, improve image adjustment efficiency, promote user's use and experience.

In this embodiment, the process of zooming in or out the perception distance of the image to be adjusted includes: determining a distance value for approximating the perception distance of the image to be adjusted, and carrying out equal-scale amplification on the image to be adjusted according to the distance value for approximating the perception distance of the image to be adjusted; or determining a distance value for zooming out the perception distance of the image to be adjusted, and carrying out equal-scale reduction on the image to be adjusted according to the distance value for zooming out the perception distance of the image to be adjusted.

Specifically, the user may include a distance value that needs to be zoomed in or zoomed out in the picture zoom-in instruction or the picture zoom-out instruction, and the distance value that needs to be zoomed in or zoomed out is determined as the adjustment value. For example, if it is desired to approximate 1%, the adjustment value is 1%. The zooming-in and zooming-out can be represented by positive and negative values of the numerical value, for example, the adjustment value of the zooming-in 1% is positive 1%, corresponding to the adjustment identifier 01; the adjustment value of zoom out 1% is minus 1%, corresponding to adjustment flag-01.

And according to the adjustment value of the perception distance of the image to be adjusted, integrally zooming the image to be adjusted. For example, according to a distance value for approximating the perception distance of the image to be adjusted, the image to be adjusted is subjected to equal-scale amplification; and according to the distance value for zooming out the perception distance of the image to be adjusted, carrying out equal-scale reduction on the image to be adjusted. The distance value to be adjusted, i.e. the adjustment value, is the scaling of the image to be adjusted. And the scaling ratios of the images to be adjusted of the left display screen and the right display screen are consistent.

The method has the advantages that the whole image to be adjusted is enlarged or reduced through equal-proportion scaling, so that the target image is consistent with the actual scene, local scaling in the image to be adjusted is avoided, and the reality of image display is improved.

In this embodiment, based on the target adjustment range, according to the image sensing distance adjustment operation sent by the user, the image to be adjusted is adjusted to obtain an adjusted image, which is a target image, and the method includes: determining an adjustment value of the perception distance of the image to be adjusted according to the image perception distance adjustment operation sent by a user; the adjusting value comprises a distance value for pushing the perception distance of the image to be adjusted and a distance value for pulling the perception distance of the image to be adjusted; if the adjustment value exceeds the target adjustment range, sending a prompt message to a user; the prompt message is used for reminding a user that the adjustment value exceeds the target adjustment range.

Specifically, when the user adjusts the image to be adjusted each time, the VR device may determine the current adjustment value according to the image sensing distance adjustment operation sent by the user, and determine whether the adjustment value exceeds the target adjustment range. The target adjustment range may be an adjustment distance threshold of an adjustment value that can be adjusted by a user, the adjustment distance threshold may be a maximum value or a minimum value of a scaling ratio, and different adjustment ranges may correspond to different adjustment distance thresholds. For example, the preset adjustment distance threshold may be 20%, that is, the distance value for the push-up cannot exceed 20%, and the distance value for the pull-out cannot exceed 20%. And determining an adjusting value for each adjustment, and comparing the adjusting value with an adjusting distance threshold value. If the adjustment value exceeds the preset adjustment distance threshold, the image to be adjusted cannot be zoomed according to the adjustment value, and a prompt message can be sent to the user to remind the user that the adjustment value reaches the upper limit of the adjustment distance threshold and needs to be adjusted again. The prompt message may be a voice message or a vibration message, and the user may perceive that the adjustment value has reached the upper limit of the adjustment distance threshold.

The adjustment distance threshold may be determined according to actual requirements, and the adjustment distance threshold that is pushed up may be the same as or different from the adjustment distance threshold that is pulled up. For example, when performing the adjustment, the adjustment operation is determined to be zoom-out or zoom-in, then the adjustment distance threshold corresponding to the adjustment operation is determined, and it is determined whether the adjustment value exceeds the adjustment distance threshold.

The beneficial effect of setting like this lies in, through setting up adjustment distance threshold, avoids the user to carry out unlimited adjustment to the perception distance, makes the user adjust to the target image as soon as possible, improves the precision and the efficiency of image adjustment.

And S804, determining the image picture after zooming in or out as a target image.

Illustratively, after the user is determined to finish the adjustment, an image picture after zooming in or zooming out is obtained, and an image of the picture is determined as a target image.

In this embodiment, obtaining the adjusted image as the target image includes: and if the adjustment value does not exceed the target adjustment range, responding to an adjustment completion instruction sent by a user, and determining the image to be adjusted corresponding to the adjustment value as a target image.

Specifically, when the user performs adjustment each time, the VR device determines whether the current adjustment value exceeds a target adjustment range, that is, the adjustment distance threshold of the target. If not, the user can see the adjusted image. And determining whether the perception distance of the adjusted image is consistent with the actual distance by the user, and if so, sending an adjustment finishing instruction by the user. For example, the user may speak via a handle or by voice. And the VR equipment responds to an adjustment completion instruction sent by a user, and determines the currently displayed image as a target image, namely, determines the image corresponding to the last adjustment value as the target image. And determining an adjustment value corresponding to the target image, wherein the adjustment value corresponding to the target image can be combined with multiple adjustment values before the adjustment is completed. For example, if the user first approaches 2% and then zooms out by 1%, and obtains the target image, it may be determined that the adjustment value corresponding to the target image is approaching 1%.

The method has the advantages that if the adjusting value does not reach the preset upper limit, the user can continue to adjust and can see the adjusted picture, so that the target image is determined, and the determining efficiency and accuracy of the target image are improved.

S805, determining a preset adjustment identifier corresponding to the image sensing distance adjustment operation, and storing the adjustment identifier; the adjustment identifier is used for indicating the adjustment of the perception distance of the image to be adjusted in the image perception distance adjustment operation.

For example, the adjustment flag may be used to indicate an adjustment value of the perceived distance of the image to be adjusted in the image perceived distance adjustment operation. When the user adjusts each time, the user can determine the adjustment identifier corresponding to the adjustment value of each adjustment, and can display the adjustment identifier on the screen of the VR device in real time. For example, the positions above the left and right display screens may be displayed, respectively.

In this embodiment, determining a preset adjustment identifier corresponding to the image sensing distance adjustment operation includes: determining an adjustment value for adjusting the perception distance of an image to be adjusted in the image perception distance adjustment operation; and determining an adjustment identifier associated with the adjustment value for adjusting the perception distance of the image to be adjusted according to the association relationship between the preset adjustment value and the adjustment identifier, wherein the adjustment identifier is an adjustment identifier corresponding to the image perception distance adjustment operation.

Specifically, when the user performs the image perceived distance adjustment operation each time, the VR device may determine an adjustment value for adjusting the perceived distance of the image to be adjusted this time. Presetting an association relation between each adjusting value and an adjusting identifier, wherein for example, the adjusting value is approximate to 1%, and the associated adjusting identifier is 01; the adjustment value is zoom out by 1%, and the associated adjustment flag is-01. And determining the adjustment value each time, and determining the adjustment identifier corresponding to the adjustment value each time according to a preset incidence relation, namely obtaining the adjustment identifier corresponding to the image perception distance adjustment operation each time.

The beneficial effect who sets up like this lies in, VR equipment confirms the adjustment sign according to user's instruction to confirm the adjustment sign with user's interpupillary distance matching, be convenient for follow-up directly carry out image adjustment according to the adjustment sign, promote user experience.

According to the image adjusting method based on the virtual reality technology, the scene image around the user is obtained through the camera on the VR device and serves as the image to be adjusted. The user may perform an image perceived distance adjustment operation, and adjust the perceived distance of the image to be adjusted within the target adjustment range, for example, the perceived distance of the image to be adjusted may be pushed or pulled. The target adjustment ranges corresponding to different users are different, the adjustment range of the user is narrowed, and the adjustment efficiency of the user is improved. And after the adjustment is finished, obtaining a target image, and enabling the perception distance of the user to the target image to be consistent with the actual distance of the user to the article. Different adjustment operations can correspond to different adjustment identifications, the adjustment identification of the image perception distance adjustment operation corresponding to the target image is determined, and the adjustment identification is stored, so that the subsequent use is facilitated. The problem of among the prior art, because the assembly interval of camera is fixed, and can't adjust the image of surrounding environment is solved, improve the flexibility of adjusting the image.
