Furthermore, the difficulty of initial start of the projector and subsequent setting after state change of the projector is reduced, the probability of debugging failure of the user is reduced, and the return rate is reduced.

[0041] As shown in Figure 1 The picture correction method for the projector provided by the embodiment of the present disclosure includes steps S101 and S102, and the method can be applied to the projector.

[0042] In step S101, in the case that it is detected that the projector has a correction abnormality, an abnormality guidance interface corresponding to the abnormality type is displayed, and guidance information for guiding the adjustment of the projector is displayed in the abnormality guidance interface. The guidance information includes at least one of a guidance animation, guidance text, and a guidance pattern.

[0043] In some embodiments, the guidance information can be used to indicate at least one of an adjustment object, an adjustment manner, an adjustment direction, an adjustment amplitude, and an adjustment target. The adjustment object includes the projector, a projection screen, etc. The adjustment manner is used to indicate how to adjust the adjustment object, such as moving, rotating, etc. The adjustment direction is used to indicate the direction required to move the adjustment object. The adjustment amplitude can indicate the size of the degree of adjustment. The adjustment target can indicate the target required after the adjustment.

[0044] The guidance animation can dynamically guide the user how to adjust the projector in the form of an animation, the guidance pattern can assist the user to understand how to adjust the projector through the form of a pattern, and the guidance text can guide the user how to adjust the projector in the form of text. The user is guided through the combination of dynamic and static, the logic is simple, the understanding cost of the user is reduced, and the usability of the projector is improved.

[0045] In step S102, in a case where it is detected that the correction exception corresponding to the abnormal type has been solved, a successful adjustment interface is displayed, and success prompt information for reminding the user of successful adjustment is displayed in the successful adjustment interface. The success prompt information can be text, pictures, etc., and the present disclosure does not limit this.

[0046] In the present embodiment, the abnormal guidance interface, the successful adjustment interface, and each interface described below for displaying to the user can be displayed through a projection screen, a control screen of a projector, or any other manner capable of displaying an interface to the user, and the present disclosure does not limit this.

[0047] In the present embodiment, the projector can perform screen automatic correction after the first boot or each subsequent boot, or can perform screen automatic correction in the use process under the operation of the user. The screen automatic correction can refer to automatically detecting and correcting the geometric distortion and position deviation of the projection screen through the sensors, algorithms, and mechanical adjustment mechanisms built in the projector, so as to ensure that the projection screen can maintain correct proportion, definition, and alignment under any installation environment or angle, thereby providing the best visual experience. The correction exception can be a failure in manual or automatic correction of the screen due to sensor errors, algorithm failures, or environmental interference, resulting in image distortion, misplacement, or failure to align, i.e., the correction exception refers to a failure of the projector to complete screen correction (screen correction failure) due to abnormal conditions, at which time the user needs to manually intervene and adjust the projector.

[0048] In some embodiments, the method can include: in the process of screen automatic correction, it can be determined whether the projector has a correction exception according to the current state data of the projector, and in a case where it is determined that the projector has a correction exception, the abnormal type is further determined according to the current state data of the projector. Then, an abnormal guidance interface corresponding to the abnormal type is generated according to the abnormal type and the current state data of the projector, and the abnormal guidance interface is displayed to the user.

[0049] The current state data of the projector can include at least one of the following: a current projection distance, a posture, a projection angle of the projector, a projection screen image obtained by the camera of the projector shooting the projection screen, and an occlusion detection result obtained by the occlusion detection of the camera of the projector.

[0050] The projection distance, also referred to as a transmission distance, is a distance between the projector and a projection screen, which can be a wall or a curtain for projection, and the present disclosure does not limit the same. The projection distance is within a distance range [s1, s2] set by the projector, so as to ensure that a normal and distortion-free picture is presented to a user after automatic or manual correction of the picture. Different projectors have a distance range set in advance, for example, the distance range can be 1.5 m to 3 m.

[0051] The posture of the projector can be a posture of the projector relative to a horizontal direction, and can include a deflection angle θ1 relative to the horizontal direction, a deflection angle θ2 relative to a vertical direction, and the like, and the present disclosure does not limit the same. The posture of the projector is within a deflection angle range set by the projector, so as to ensure that a normal and distortion-free picture is presented to a user after automatic or manual correction of the picture. Different projectors have a deflection angle range set in advance, and the present disclosure does not limit the same.

[0052] The projection angle can be an angle between the camera of the projector and the projection screen, and the angle includes a first angle α1 of a center line of the camera relative to a horizontal direction of a plane on which the projection screen is located and a second angle α2 of the camera relative to a vertical direction of the plane on which the projection screen is located. The horizontal direction of the plane on which the projection screen is located can be any straight line parallel to a horizontal frame of the projection screen, such as a curtain, or any straight line parallel to the ground within the plane on which the projection screen is located. The vertical direction of the plane on which the projection screen is located can be any straight line perpendicular to the plane on which the projection screen is located. The first angle and the second angle of the projector are respectively within a preset angle range, so as to ensure that a normal and distortion-free picture is presented to a user after automatic or manual correction of the picture. Different projectors have a first angle and a second angle respectively corresponding to a preset angle range, and the present disclosure does not limit the same.

[0053] In some embodiments, the abnormality type of the correction abnormality can include any one of the following: a distance type, a picture coverage type, a projection angle type, a horizontal inclination type, and a camera blocking type. In this way, the user can more intuitively understand which aspect of the projector needs to be adjusted through classification, facilitating the user to understand.

[0054] The distance type correction abnormality can mean that the current projection distance s of the projector is too far or too close, i.e. The projection distance can be detected by a device capable of detecting distance, such as an infrared sensor, a ToF sensor (Time of Flight sensor, also referred to as a flight time sensor), and the like, provided in the projector.

[0055] The correction anomaly of the projection angle type can refer to that at least one of the first angle a1 and the second angle a2 is not within a preset angle range, that is and / or The projection angle can be determined based on detection data of a gyroscope, a distance detection device or the like provided in the projector.

[0056] The correction anomaly of the horizontal tilt type can refer to that the deflection angle θ1 of the projector relative to the horizontal direction is not within a corresponding angle range, that is The deflection angle θ1 of the projector relative to the horizontal direction can be detected by a level or the like provided in the projector.

[0057] The correction anomaly of the picture coverage type can refer to that the projection picture does not cover the four frames of the projection screen with a detectable frame such as a curtain. The projector can control the camera to take an image to determine whether the projection picture covers the projection screen according to the projection screen image obtained by the shooting. For the projection screen with a frame such as a curtain, the detection of the correction anomaly of the picture coverage type is needed, while for the projection screen without a frame such as a wall, the detection of the correction anomaly of the picture coverage type is not needed. Therefore, the projector can first determine whether the current projection screen is a projection screen with a frame such as a curtain, and then determine whether the detection of the correction anomaly of the picture coverage type is needed. In some embodiments, the projector can determine that the current projection screen is a projection screen with a frame such as a curtain when it is detected that the projection screen has been paired and connected to the projector, or there is part of the frame in the projection screen image, and then determine that the detection of the correction anomaly of the picture coverage type is needed. The projector can determine that the current projection screen is a projection screen without a frame such as a wall when it is detected that the projection screen has not been paired and connected to the projector, or there is no frame in the projection screen image, and then determine that the detection of the correction anomaly of the picture coverage type is not needed.

[0058] The correction anomaly of the camera blocking type can refer to that there is a stain on the camera of the projector or the front of the camera is blocked. The projector itself can determine whether the correction anomaly of the camera blocking type exists by a blocking detection result obtained by blocking detection. The projector can obtain the blocking detection result by at least one of the following ways: obtaining the blocking detection result by a self-provided infrared sensor, obtaining the blocking detection result by infrared sensor blocking detection on the projection field of view, controlling the camera to take a picture of the projection picture to obtain a picture image, and then obtaining the blocking detection result by blocking detection on the picture image, and the like, which are not limited in the present disclosure.

[0059] In the present embodiment, the guidance information required to be displayed in the abnormality guidance interface is different under different abnormality types, so as to facilitate the user to more intuitively understand how to adjust the projector. The following will be described in combination with Figures 2-6The abnormal guidance interface shown is illustrated below.

[0060] like Figure 2 As shown, if the anomaly type is distance-related and the projection distance s is greater than s2, the guidance text displayed in the anomaly guidance interface can be "Please move the projector closer to the wall" (adjustment object and adjustment method) and "The best correction effect is within 1.5 to 3 meters" (adjustment target). The guidance icon includes a depth or perspective line (blue dotted line) located in the center of the interface, and the guidance animation includes an arrow animation reminding the user to move the projector closer to the wall or other projection screen (adjustment direction). Conversely, if the anomaly type is distance-related and the projection distance s is less than s1, the guidance text displayed in the anomaly guidance interface can be "Please move the projector further away from the wall" and "The best correction effect is within 1.5 to 3 meters." The guidance icon includes a depth or perspective line located in the center of the interface, and the guidance animation includes an arrow animation reminding the user to move the projector away from the wall or other projection screen.

[0061] like Figure 3 As shown, if the exception type is screen overlay, the guidance text that can be displayed in the exception guidance interface is "Please move the device" (adjust the object and adjustment method) and "Let the projected image completely cover the four borders of the screen" (adjust the target). The guidance animation can include a directional arrow animation reminding the user to move the projector (adjust the direction).

[0062] like Figure 4 As shown, if the exception type is projection angle and the first angle α1 is greater than α12, the guidance text displayed in the exception guidance interface can be "Please adjust the projection angle to the left" (adjusting direction and object) and "Try to straighten the projector" (adjusting target). The guidance icon includes a center line (blue dotted line) located in the center of the interface, and the guidance animation includes an arrow animation reminding the user to move the projector to the left (adjusting direction). Conversely, if the exception type is projection angle and the first angle α1 is less than α11, the guidance text displayed in the exception guidance interface can be "Please adjust the projection angle to the right" and "Try to straighten the projector." The guidance icon includes a center line located in the center of the interface, and the guidance animation includes an arrow animation reminding the user to move the projector to the right.

[0063] like Figure 5 As shown, if the exception type is horizontal tilt, the guidance text displayed in the exception guidance interface can be "Please adjust the horizontal angle" (the object to be adjusted) and "It is recommended that the tilt angle not exceed 15 degrees" (the target to be adjusted). The guidance icons include a horizontal center line (red dashed line) indicating the current horizontal center of the projector and a horizontal center line (blue dashed line) to which the projector needs to be adjusted. The angle between the two center lines indicates the adjustment range. The guidance animation includes an arrow animation reminding the user to rotate the projector (adjustment direction).

[0064] like Figure 6 As shown, if the exception type is "Camera Obstruction," the guidance text displayed in the exception guidance interface can be "Camera is obstructed?" or "Please check if there is any obstruction or dirt in front of the camera" (adjustment method). In some embodiments, such as Figure 6 As shown, the error guidance interface can also include an unobstructed view control, which can also have the text message "I have confirmed that the camera is unobstructed." Upon detecting a trigger operation on this unobstructed view control, it is determined that the user has removed the camera obstruction, and the camera obstruction-related error no longer exists.

[0065] In some embodiments, the method may further include: adjusting the guidance information displayed in the abnormal guidance interface in response to the current state data of the projector. Since users may over-adjust or under-adjust the projector during the process of adjusting it based on the abnormal guidance interface, or other types of abnormalities may be introduced during the adjustment process, the method can determine in real-time based on the current state data what adjustments the projector still needs after the user's adjustments, and then adjust the guidance information displayed in the abnormal guidance interface accordingly. For example, displaying... Figure 5 The abnormal guidance interface shown is incorrect because the user adjusted it too far to the left, causing the first angle α1 to be less than α11. Therefore, the displayed information can be changed. Figure 5 The abnormal guidance interface shown has been replaced with Figure 6 The error guidance interface shown allows users to adjust the projector in a timely manner.

[0066] In some embodiments, the method may further include: upon detecting a calibration anomaly in the projector, issuing a guiding voice message, the content of which matches the guiding information displayed in the anomaly guidance interface. This allows the guiding voice message to assist the user in moving the projector. For example, the guiding voice message could be the voice message corresponding to the guiding text displayed in the anomaly guidance interface, and this disclosure does not impose any limitations on this.

[0067] In some embodiments, since the calibration anomaly detected by the projector may include at least one of the above-mentioned anomaly types, if a calibration anomaly is detected in the projector and there are multiple anomaly types, one of the anomaly types can be selected first to generate the guidance information required to be displayed on the anomaly guidance interface. Then, the anomaly guidance interface is displayed to the user and the subsequent step S102 is executed. After step S102, it is re-determined whether a calibration anomaly exists, and if a calibration anomaly exists, the above process is repeated until the projector is adjusted to meet the image calibration requirements.

[0068] In some embodiments, the content in the adjustment success interface shown after the abnormal guiding interface can have a correlation with the guiding information shown in the abnormal guiding interface, so that the user can be reminded of which type of correction abnormality adjustment for the projector has been successfully completed. In some embodiments, the interface features of the abnormal guiding interface and the adjustment success interface can be different; the interface features include at least one of the following: a border, a background. The difference in interface features can facilitate the user to intuitively distinguish through the interface whether the displayed interface is an abnormal guiding interface or an adjustment success interface, and facilitate the user to determine whether the adjustment is successful through the explicit change of the interface features after successfully adjusting the projector. The difference in interface features can be embodied in the following ways: the color, shape, etc. of the border are different, the color, pattern, etc. of the background are different, and the present disclosure does not limit this.

[0069] The correlation can be embodied as the same display elements or interface features contained between the two interfaces. The display elements include patterns, colors, texts, etc. For example, Figure 2 The abnormal guiding interface and the adjustment success interface shown thereafter both show a blue schematic line, Figure 4 The abnormal guiding interface and the adjustment success interface shown thereafter both show a center schematic line (blue dashed line), and the abnormal guiding interface and the adjustment success interface shown thereafter both show a horizontal center schematic line (blue dashed line), which all embody the correlation between the two interfaces. Figure 2 、 Figure 3 The abnormal guiding interface shown is a red border, and the adjustment success interface shown thereafter is a blue border, Figure 4 The abnormal guiding interface shown has a part of the red area in the background, and the adjustment success interface shown thereafter has a part of the blue area in the background and the position of the area is the same as that of the red area in the abnormal guiding interface. The difference in border color and background color facilitates the user to determine whether the adjustment is successful through the change of the interface.

[0070] In some embodiments, the method can further include: in the case where it is detected that the correction abnormality corresponding to the abnormal type has been solved, issuing an adjustment success voice and / or an adjustment success prompt tone. In this way, the user can be provided with all-around reminders of eyes and ears based on the adjustment success interface, the adjustment success voice, and the adjustment success prompt tone, so as to facilitate the user to determine that the adjustment has been successful through the adjustment success voice and / or the adjustment success prompt tone when the user cannot see the interface content in time (such as adjusting the projector while facing away from the projection screen).

[0071] The adjustment success voice can be a voice corresponding to the successfully adjusted abnormal type, for example, the adjustment success voice can be a voice corresponding to the success prompt information in the adjustment success interface being displayed, and the present disclosure does not limit this. The adjustment success prompt sound can be a pre-set sound effect, and the adjustment success prompt sounds emitted by different adjustment success interfaces can be the same or different, and the present disclosure does not limit this.

[0072] In some embodiments, the method further comprises: in a case where it is detected that the projector is adjusted to meet the picture correction requirement, displaying an automatic correction prompt in the adjustment success interface, the automatic correction prompt being used to remind the user to perform automatic correction on the adjusted projector, and then performing picture automatic correction in a case where it is determined according to a response of the user to the automatic correction prompt that automatic correction is needed. Figures 2-5

[0073] The automatic correction prompt can be a control, and if a triggering operation for the control is detected, it can be determined that automatic correction is needed, and then picture automatic correction is performed. Figures 2-5 The automatic correction prompt can further display a countdown for automatic start of the automatic correction, and if no other operation of the user is detected before the countdown is completed, it can be determined that automatic correction is needed, and then picture automatic correction is performed. Figures 2-5

[0074] The picture automatic correction can refer to automatically detecting and correcting geometric distortion and position deviation of a projection picture by using a sensor, an algorithm and a mechanical adjustment mechanism built in the projector, so as to ensure that the projection picture can maintain correct proportion, definition and alignment in any installation environment or angle, thereby providing the best visual experience.

[0075] In some embodiments, as shown in Figure 7 The method can further comprise: in a case where it is determined that the picture automatic correction fails, displaying an automatic correction failure interface, and the automatic correction failure interface displays at least one of the following: an automatic correction again prompt, a manual correction prompt and a projector adjustment prompt.

[0076] The projector adjustment prompt is used to remind the user to re-adjust the projector, for example, the projector adjustment prompt can be Figure 7 “Please adjust the projection distance, angle and do not block the camera”.

[0077] ​​In some embodiments, after displaying the automatic correction failure interface for the user, the abnormality guidance interface corresponding to the abnormality type can be displayed in response to the user making an adjustment operation (e.g., moving the projector, adjusting the angle of the projector, removing the blocking object, etc.) until the adjustment is successful. Alternatively, the abnormality guidance interface can be displayed in response to the user touching a control or key that displays the abnormality guidance interface, the user issuing a shortcut operation to display the abnormality guidance interface. The abnormality guidance interface can also automatically jump to after a preset period of time after the automatic correction failure.
