detailed description

Exemplary embodiments of the present disclosure will be described in detail herein with reference to the drawings. The following description refers to the same or similar elements in the different figures unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments of the present disclosure. Rather, they are merely examples of devices and methods of some aspects of the present disclosure.

When an electronic device is used to project an image or a video to be displayed on a surrounding wall surface, the brightness of the wall may be uneven and the surface may be uneven, which may cause local distortion of the projected image on the wall surface, thereby reducing the user. Viewing experience.

FIG. 1 is a flow chart of a projection method in accordance with an embodiment of the present disclosure. For convenience of description, as an example, in the subsequent embodiments, the projection method is performed with a processor in an electronic device as an execution subject. However, it should be noted that the use of a processor as an execution subject is not limiting. Referring to Figure 1, the projection method includes

steps

101 and 102.

At step 101, the position of the distorted area in the projected image is determined.

The electronic device projects the image to be displayed onto the projection surface (for example, the wall surface) through the projection module, and then presents the image to the user in the manner of projecting the image. The distortion area in the projected image can be determined in the following manner.

Method 1: Manual mode. In this mode, the electronic device is provided with a manual adjustment module, and the manual adjustment module can receive the user's operation. For convenience of explanation, the operation of moving the editing window by the user is referred to as a moving operation in the subsequent content, and the operation of adjusting the distortion parameter of the image in the editing window by the user is referred to as an adjustment operation. The editing window is such a window that the image located in the editing window can be edited, for example, the distortion parameter of the image is adjusted. As an example, the manual adjustment module may include one or more of a rocker, a direction button, and a touch button.

It can be understood that the above edit window can be displayed during the projection process, or can be displayed in response to the user's trigger operation.

When the user views the projected image, if there is a distorted area in the projected image, the user performs a moving operation by manually adjusting the module (ie, moving the operation of the editing window). The manual adjustment module generates a corresponding trigger signal according to the correspondence between the movement operation and the trigger signal, and sends the trigger signal to, for example, a processor. The processor adjusts the position of the editing window based on the trigger signal. For example, the trigger signal may correspond to the offset position. At this time, the offset position may be superimposed on the basis of the current position of the edit window, and the sum of the vectors of the two positions is used as the position of the edit window after the move operation.

If the time during which the edit window remains in the same position exceeds the set threshold, or the user "determines" the position, the position of the edit window after the move operation is taken as the position of the distortion area in the projected image.

Method 2: Automatic mode. In this mode, an image acquisition module can be disposed on the electronic device. The image acquisition module is coupled to the processor and configured to acquire a projection image of the projection area and transmit the acquired projection image to the processor.

The processor determines the position of the distortion region from the acquired projection image according to a preset image recognition algorithm. The image recognition algorithm may determine the location of the distorted region in the following manner, for example, all of which may be performed by the processor.

Method 1: Determine a coordinate system based on the projection surface (hereinafter referred to as the first coordinate system), and determine another coordinate system based on the image to be displayed (hereinafter referred to as the second coordinate system). Then, by mapping each pixel point in the projected image to the image to be displayed, a correspondence relationship between the first coordinate system and the second coordinate system is obtained. Based on the above manner, the correspondence between the first coordinate system and the second coordinate system is stored in advance.

After the projection image is acquired, according to the correspondence relationship between the first coordinate system and the second coordinate system, the collected projection image is mapped to the image to be displayed, and then the mapped projection image and the image to be displayed are analyzed to determine the distortion pixel. The coordinates (the pixels at the same position cannot be matched), and finally the coordinate positions of all the distorted pixels are counted to obtain the position of the distorted area.

Manner 2: extracting image features (such as edge features, gray value rate change characteristics, etc.) in the image to be displayed and the projected image, respectively, and then filtering out the noise features in the image features of the projected image. The noise characteristic refers to a newly added image feature in most areas of the projected image compared with the image features of the image to be displayed. Then, comparing the image features of the image to be displayed and the image features of the filtered projection image, the position where the image feature changes may be determined, and the changed position is used as the distortion region of the projected image.

Of course, the technician can select other image recognition algorithms according to the specific scene, and all the schemes that can determine the location of the distortion region are also conceived.

Step 102: Adjust an image projected into the distortion region according to a set policy according to a position of the distortion region.

In this embodiment, after determining the position of the distortion area, the processor may adjust the image projected into the distortion area according to the set strategy, so that the image in the distortion area is consistent with the image in other areas of the projected image (ie, , so that the projected image in the projection area looks undistorted).

Among them, the set strategy can include:

Strategy 1: The manual adjustment module continues to monitor the user's adjustment operations. The user selects the distortion parameter (such as shape, size, brightness, etc.) of the image of the distortion area to be adjusted by manually adjusting the module, and then the manual adjustment module generates an adjustment signal according to the adjustment operation of the user to send to the processor. The processor adjusts the distortion parameter corresponding to the image in the distortion region according to the adjustment signal. For example, the user adjusts the brightness of the distortion area by manually adjusting the module selection, and then inputs the adjusted brightness value. Then, (for example, the processor) adjusts the brightness value of the image in the distorted area according to the brightness value.

Strategy 2: using (for example, a processor) image recognition model to identify the distortion type of the image of the distortion region, and then adjusting the image corresponding to the distortion type in the distortion region based on the correspondence between the previously stored distortion type and the distortion parameter Distortion parameters, so that the image of the adjusted distortion area is consistent with the image of other areas. For example, when the image recognition algorithm determines the undistorted region in the projected image of the adjusted projection region acquired by the image acquisition module, it may be determined that the image of the adjusted distortion region is consistent with the image of the other region.

It can be understood that the image recognition model for identifying the distortion type and the distortion position in this embodiment may be the same image recognition model or different image recognition models. Taking different image recognition models as an example, after determining that the projected image has a distortion region, the image of the distortion region and the image to be displayed are input to an image recognition model for identifying the distortion type, and then the image of the distortion region is recognized by the image recognition model. The type of distortion. As an example, the distortion type may be size distortion, uneven brightness, and the like. Then, (for example, the processor) determines the distortion parameter that needs to be adjusted according to the correspondence relationship between the distortion type and the distortion parameter, and adjusts the distortion parameter of the image in the distortion region corresponding to the distortion type. As an example, when determining that the distortion type is size distortion, it is determined that the distortion parameters that need to be adjusted are shape, size, curvature, etc., and when it is determined that the distortion type is brightness, it is determined that the distortion parameter that needs to be adjusted is brightness.

It can be seen that, in this embodiment, the position of the distortion region in the projected image is determined manually or automatically, and then the processor adjusts the image projected into the distortion region according to the set strategy, so that the image in the distortion region and the projected image are The images in other locations are consistent. That is, in the embodiment, the projection image in the projection area can be made without distortion without replacing the projection surface, and the viewing experience of the user is ensured.

The projection method in different modes will be described in detail below with reference to the flowchart and the scene graph. 2 is a schematic flow chart of a projection method according to an embodiment of the present disclosure, and FIGS. 3-6 are schematic diagrams of an application scenario in which the projection method of FIG. 2 is applied, according to an embodiment of the present disclosure. The method as shown in Figure 2 includes steps 201-205. At step 201, a trigger signal is acquired that is generated based on a user's movement operation. At step 202, the position of the edit window is adjusted based on the trigger signal. At step 203, after the user's movement operation is completed, it is determined that the position of the editing window is the position of the distortion area. At step 204, an adjustment signal is acquired that is generated based on a user's adjustment operation. At step 205, a distortion parameter of the image in the distorted region is adjusted based on the adjustment signal.

Referring to FIG. 3, the top edge of the electronic device 11 is provided with a projection module 111 (marked by a dotted line to indicate that it is not visible in the direction shown in FIG. 3), and the user (for example, using the finger 10 to touch) adjusts the "projection adjustment mode" in advance. It is "manual mode". At the time of projection, the user adjusts the direction of the projection module 111 to project the image to be displayed to the projection surface 12, and the imaged area of the image to be displayed on the projection surface 12 is the projection area 13. Due to the presence of the protrusions 121 on the projection surface 12, the distortion area 14 is present in the projected image within the projection area 13 viewed by the user.

Referring to FIG. 4, when the user touches the display module of the electronic device 11, the direction operation window 15 and the edit window 16 are popped up in the display area. As an example, the direction operation window 15 includes four movement keys (ie, a manual adjustment module) of "upward", "downward", "leftward", and "rightward", see the arrows in the directions shown in FIG. . The initial position of the center position of the edit window 16 is P1. The user performs a moving operation by the direction operation window 15, for example, operates (or touches) two moving buttons of "down" and "right" to move the center position of the editing window 16 to P2, thereby making the edit window 16 after the movement. The projection 26 covers the distortion region 14. It should be noted that, in order to clarify the positional relationship between the editing window 16 and the distortion area 14, the size of the distortion area 14 and the editing window 16 are appropriately adjusted in the drawing, so that it is more convenient to understand.

In some embodiments, the position of the edit window may be moved in a set step size in response to a trigger signal transmitted by touching the move button, and may also be based on the initial position P1 of the edit window 16 and the touch "down" and "toward" The movement step of the right "two moving buttons" determines the position P2 after the movement.

After each movement operation is completed, the trigger signal corresponding to the user's "OK" operation is monitored, and after the time is more than 2 seconds (can be set according to the specific situation), it can be determined that the user's movement operation is completed, and the editing at this time is determined. The position of the window 16 is the position of the distorted area, that is, the position P2.

In some embodiments, the display module of the electronic device 11 can continue to be touched. Referring to FIG. 5, a pull-down menu 17 is displayed in the display area, which includes a list of distortion parameters. Then, the adjustment operation may be performed by the user by, for example, adjusting the distortion parameter such as “curvature” in the list, to adjust the image in the distortion region 14 according to the adjustment signal generated by the adjustment operation, and finally presented to the user as shown in FIG. 6 . Projected image (undistorted projected image).

It can be seen that, in this embodiment, the distortion parameter can be adjusted according to the operation of the user, so that the image in the distortion region is consistent with the image of other regions in the projected image, so that the projection image can be completed without replacing the projection surface. Sexuality enhances the user's viewing experience. In addition, in this embodiment, the interaction between the user and the electronic device can be improved, and the fun of using the projection function can be improved.

FIG. 7 is a schematic flow chart of still another projection method in accordance with an embodiment of the present disclosure. Referring to Figure 7, the method includes steps 701-704. In step 701, a projected image of the projected area is acquired. At step 702, the location of the distorted region is determined from the projected image using a pre-set image recognition algorithm. At step 703, a distortion type of the image in the distorted region is determined according to the image to be displayed and the image in the distorted region. At step 704, based on the correspondence between the distortion type and the distortion parameter, the distortion parameter of the image in the distortion region corresponding to the distortion type is adjusted.

As an example, the electronic device 11 in this embodiment is provided with an image acquisition module 18, which can be arranged on the back side of the electronic device 11 shown in FIG. 3-6 (as shown by the dotted line in FIG. 3 (indicating that the front side cannot See)), front side or even separate from the electronic device 11. The position of the image acquisition module is not limited as long as it can acquire a projected image. The image acquisition module can be, for example, a camera. After the user selects the "automatic mode" shown in FIG. 3, the projection module 111 projects the image to be displayed to the projection area 13. Thereafter, the image acquisition module 18 acquires a projected image of the projected area 13 and transmits the acquired projected image to, for example, a processor. (For example, the processor) identifies the position of the distorted region from the acquired projected image using a preset image recognition algorithm. Then, the image to be displayed and the image in the distortion region are analyzed to determine the distortion type of the image in the distortion region. Finally, according to the correspondence between the pre-stored distortion type and the distortion parameter, the distortion parameter corresponding to the distortion type of the image in the distortion region is adjusted.

It can be seen that, in this embodiment, by setting an image acquisition module to collect a projection image, and then processing the projection image by the processor, the distortion region can be adjusted, and the user can replace the projection surface to ensure the distortion-free region of the projection image, which is beneficial to improving the user.
