Description

Scanning method and electronic equipment

Technical Field

The present disclosure relates to the field of electronic devices, and in particular, to a scanning method and an electronic device.

Background

With the development of electronic device technology, more and more electronic devices have a document scanning function. For example, when the electronic device uses the document scanning function, the electronic device may scan a photographed object such as a paper document, so that information (such as a text or a picture) in the photographed object may be extracted, and an electronic scan piece corresponding to the photographed object may be converted, so that a user may conveniently view and edit the document.

When the electronic equipment scans a paper shot object by using a document scanning function, the electronic equipment needs to be relatively parallel to a plane where the shot object is located, so that the electronic equipment can obtain a clear electronic scanning piece.

However, when the electronic apparatus is not parallel to the plane in which the subject is photographed, the electronic scan obtained by the electronic apparatus may be unclear. This results in that the user needs to adjust the position of the electronic device or the object to be photographed, so that the electronic device is parallel to the plane where the object to be photographed is located, resulting in troublesome operation of the user.

Disclosure of Invention

The embodiment of the application provides a scanning method and electronic equipment, which can avoid that a user needs to adjust the position of the electronic equipment or a shot object when the electronic equipment is not parallel to the plane where the shot object is located, so that the operation of the user is reduced.

In order to achieve the above purpose, the embodiment of the application adopts the following technical scheme:

in a first aspect, an embodiment of the present application provides a scanning method, applied to an electronic device, where the electronic device may include a document scanning function, where the scanning method may include: receiving an opening operation of a user on a document scanning function; responding to the opening operation of a user on a document scanning function, displaying a scanning interface, wherein the scanning interface comprises a determining scanning control; determining a first included angle, wherein the first included angle is an included angle between a plane where a shot object is located and electronic equipment; determining a target angle required to rotate by a camera of the electronic equipment based on the first included angle; controlling the camera to rotate a target angle; after the camera rotates a target angle, the plane where the shot object is positioned is in a parallel state with the camera; receiving triggering operation of a user on determining a scanning control; responding to the triggering operation of the user on the determined scanning control, scanning the shot object through a camera after rotating the target angle, and acquiring scanning information of the shot object; and obtaining the electronic scanning piece corresponding to the shot object according to the information of the shot object.

Based on the method of the first aspect, before the electronic device scans the photographed object, the electronic device can determine the target angle required to rotate by the camera in real time, and rotate the camera by the target angle, and after the camera rotates by the target angle, the plane where the photographed object is located is in a parallel state with the camera, so that the photographed object can be all in a depth of field range corresponding to the camera after rotating by the target angle. Therefore, when the electronic device scans the shot object through the camera after the rotation target angle, the shot object can be all in the depth of field range corresponding to the camera after the rotation target angle, so that a clear electronic scanning piece can be obtained. Therefore, when the plane where the electronic equipment and the shot object are located is not parallel, the user needs to adjust the position of the electronic equipment or the shot object, so that the plane where the electronic equipment and the shot object are located is not parallel, the operation of the user can be reduced, and the experience of the user is improved.

With reference to the first aspect, in another possible implementation manner, determining the first included angle may include: acquiring distances between the electronic equipment and a plurality of detection points in a plane where the shot object is located; and determining a first included angle according to the distance between the electronic equipment and a plurality of detection points in the plane of the shot object.

Based on the possible implementation manner, the electronic device may determine an included angle between the plane in which the object is photographed and the electronic device according to distances between the electronic device and a plurality of detection points in the plane in which the object is photographed. Therefore, the target angle of the camera of the electronic equipment, which is required to rotate, can be determined according to the included angle between the plane where the shot object is located and the electronic equipment, namely, the angle of the camera of the electronic equipment, which is required to incline, can be determined, so that after the camera rotates the target angle, the plane where the shot object is located is in a parallel state with the camera.

With reference to the first aspect, in another possible implementation manner, the plurality of detection points may include a first target detection point and a second target detection point, and determining the first included angle according to a distance between the electronic device and the plurality of detection points in a plane where the object is photographed may include: determining a second included angle according to the first target detection point and the second target detection point, wherein the second included angle is an included angle between the first connecting line and the second connecting line; the first connecting line is a connecting line between the first target detection point and the electronic equipment, and the second connecting line is a connecting line between the second target detection point and the electronic equipment; determining a first included angle according to the first distance, the second distance and the second included angle; the first distance is the distance between the first target detection point and the electronic equipment, and the second distance is the distance between the second target detection point and the electronic equipment.

Based on the possible implementation manner, the electronic device may determine an included angle between the plane in which the object is photographed and the electronic device according to a distance between the electronic device and the first target detection point and the second target detection point in the plane in which the object is photographed and an included angle between the first connection line and the second connection line. Therefore, the target angle of the camera of the electronic equipment, which is required to rotate, can be determined according to the included angle between the plane where the shot object is located and the electronic equipment, namely, the angle of the camera of the electronic equipment, which is required to incline, can be determined, so that after the camera rotates the target angle, the plane where the shot object is located is in a parallel state with the camera.

With reference to the first aspect, in another possible implementation manner, when the display screen of the electronic device is in a portrait display state, the first target detection point may be a detection point corresponding to an upper edge of the object to be shot or a detection point corresponding to a lower edge of the object to be shot, and the second target detection point may be a detection point corresponding to a vertical line of the electronic device on a plane where the object to be shot is located.

Based on the possible implementation manner, the electronic device can accurately determine the included angle between the plane where the shot object is located and the electronic device according to the detection point corresponding to the upper edge of the shot object or the detection point corresponding to the lower edge of the shot object and the detection point corresponding to the vertical line of the electronic device on the plane where the shot object is located. Therefore, the target angle of the camera of the electronic equipment, which is required to be rotated, can be accurately determined according to the accurate included angle between the plane where the shot object is located and the electronic equipment, namely, the angle of the camera of the electronic equipment, which is required to be inclined, can be determined, so that after the camera rotates the target angle, the plane where the shot object is located and the camera are in a parallel state.

With reference to the first aspect, in another possible implementation manner, determining the first included angle according to the first distance, the second distance, and the second included angle may include: determining a first included angle based on a first preset formula according to the first distance, the second distance and the second included angle; the first preset formula is:the method comprises the steps of carrying out a first treatment on the surface of the Wherein,for the first angle, H1 is the first distance, H2 is the second distance, ++>Is a second included angle.

Based on the possible implementation manner, the electronic device can accurately determine the included angle between the plane where the photographed object is located and the electronic device through a first preset formula. Therefore, the target angle of the camera of the electronic equipment, which is required to be rotated, can be accurately determined according to the accurate included angle between the plane where the shot object is located and the electronic equipment, namely, the angle of the camera of the electronic equipment, which is required to be inclined, can be determined, so that after the camera rotates the target angle, the plane where the shot object is located and the camera are in a parallel state.

With reference to the first aspect, in another possible implementation manner, determining the first included angle may include: acquiring a phase difference between adjacent photodiode PD points of the electronic device; and determining a first included angle according to the phase difference between the adjacent PD points and a preset corresponding relation.

Based on the possible implementation manner, the electronic device can determine the included angle between the plane where the photographed object is located and the electronic device according to the phase difference between the adjacent photodiode PD points. Therefore, the target angle of the camera of the electronic equipment, which is required to rotate, can be determined according to the included angle between the plane where the shot object is located and the electronic equipment, namely, the angle of the camera of the electronic equipment, which is required to incline, can be determined, so that after the camera rotates the target angle, the plane where the shot object is located is in a parallel state with the camera.

With reference to the first aspect, in another possible implementation manner, determining, based on the first included angle, a target angle of rotation required by a camera of the electronic device may include: determining an object distance between a shot object and electronic equipment and a focal length corresponding to a camera of the electronic equipment; and determining a target angle required to rotate the camera of the electronic equipment according to the object distance between the shot object and the electronic equipment, the focal length corresponding to the camera of the electronic equipment and the first included angle.

Based on the possible implementation manner, the electronic device can accurately determine the target angle required to rotate by the camera of the electronic device according to the object distance between the shot object and the electronic device, the focal length corresponding to the camera of the electronic device and the included angle between the plane where the shot object is located and the electronic device. Therefore, the target angle of the camera of the electronic equipment, which is required to be rotated, can be accurately determined according to the accurate included angle between the plane where the shot object is located and the electronic equipment, namely, the angle of the camera of the electronic equipment, which is required to be inclined, can be determined, so that after the camera rotates the target angle, the plane where the shot object is located and the camera are in a parallel state.

With reference to the first aspect, in another possible implementation manner, determining the target angle required to rotate the camera of the electronic device according to the object distance between the photographed object and the electronic device, the focal length corresponding to the camera of the electronic device, and the first included angle may include: according to the object distance between the shot object and the electronic equipment and the focal length corresponding to the camera of the electronic equipmentThe first included angle is used for determining a target angle based on a second preset formula; the second preset formula is:the method comprises the steps of carrying out a first treatment on the surface of the Wherein (1)>And (2) taking μ as a first included angle, taking the object distance between the shot object and the electronic equipment, f as the focal length corresponding to the camera of the electronic equipment, and θ as a target angle.

Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

The terminology used in the following embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates to the contrary. It should also be understood that "/" means or, e.g., A/B may represent A or B; the text "and/or" is merely an association relationship describing the associated person, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist together, and B exists alone.

With the development of electronic device technology, more and more electronic devices have a document scanning function, that is, the electronic devices may have a document mode. When a user uses the document scanning function through the electronic equipment, the electronic equipment can scan the shot object when the electronic equipment opens the document scanning mode, so that information in the shot object can be extracted and converted into an electronic scanning piece corresponding to the shot object. After the electronic scanning piece corresponding to the shot object is obtained, the electronic equipment can display the electronic scanning piece, so that the electronic equipment can be convenient for a user to check and edit.

The shot object can be a document, a picture, a table or the like. That is, the object may be a document, a picture, a form, or the like of paper, or may be a document, an image, a form, or the like displayed by another electronic device. When the object is a document, the information in the object is text information, image information, form information, or the like in the document, when the object is an image, the information in the object is text information, image information, form information, or the like in the image, and when the object is a form, the information in the object is text information, image information, form information, or the like in the form.

When the electronic device scans the shot object by using the document scanning function, the electronic device needs to be relatively parallel to the plane of the shot object, so that the electronic device can obtain a clear electronic scanning piece. When the plane where the electronic equipment and the shot object are located is kept relatively parallel, the depth of field range corresponding to the camera of the electronic equipment is larger, and the shot object cannot exceed the depth of field range corresponding to the camera, so that the electronic equipment can obtain a clear electronic scanning piece through the larger depth of field range.

Depth of field (DOF) refers to the range in which a scene within a certain distance from the front of the camera (i.e., lens) of an electronic device can remain in clear focus. The depth of field is affected by a number of factors including the focal length, aperture, distance of the camera from the object to be photographed, etc. A smaller aperture and a longer focal length generally produce a larger depth of field so that both front and back scenes remain clear, while a larger aperture and a shorter focal length produce a shallow depth of field so that only scenes within a specific distance range remain clear and other areas are in a blurred state.

When the shot object is positioned in the depth of field range corresponding to the camera of the electronic device, the electronic device can obtain a clear electronic scanning piece, and when the shot object is positioned in the depth of field range, the electronic device cannot obtain the clear electronic scanning piece corresponding to the part of the content of the shot object beyond the depth of field range.

That is, when the plane where the electronic device and the object to be photographed are located is kept relatively parallel, the depth of field range corresponding to the camera of the electronic device is large, and the object to be photographed can be located in the depth of field range corresponding to the camera entirely, so that the depth of field range corresponding to the camera cannot be exceeded. When the object to be photographed is scanned (may also be referred to as photographing) through the large depth of field range, the object to be photographed may be located entirely within the large depth of field range, so that the electronic device may obtain a clear electronic scan (i.e., the object to be photographed of the electronic board) through the camera.

For example, taking a document with a photographed object being paper as an example, when an electronic device (such as a mobile phone) uses a document scanning function to scan the photographed object, the electronic device and a plane where the photographed object is located are kept relatively parallel, and the electronic device can obtain a clear electronic document (i.e. an electronic scanning piece corresponding to the photographed object) to perform schematic description.

After a user opens a document scanning mode on the electronic device, the electronic device may display a document scanning interface 101, as shown in fig. 1 (a), and the document scanning interface 101 may include a scanning control 102. Thereafter, the user may scan (i.e., photograph) the paper document 103 using the electronic device. In order to obtain a clear electronic version document, a user can keep the electronic device and the plane where the paper document 103 is located relatively parallel, so that the depth of field range corresponding to the camera of the electronic device is larger, and the paper document 103 can be completely located in the depth of field range corresponding to the camera.

After the user has kept the electronic device relatively parallel to the plane in which the paper document 103 lies, the user activates the scan control 102 so that the electronic device can scan the paper document 103. That is, when the electronic device receives a triggering operation, such as a clicking operation, of the user on the scan control 102, the electronic device may scan the paper document 103 in response to obtain document information (such as text information) corresponding to the paper document 103. After the electronic device obtains the document information corresponding to the paper document 103, the electronic device may perform format conversion on the document information corresponding to the paper document 103, such as converting to an electronic version of the document. Thereafter, as shown in (b) of fig. 1, the electronic device may display an electronic version document 104 corresponding to the paper document 103.

When the electronic device is kept relatively parallel to the plane in which the paper document 103 is located, the depth of field range corresponding to the camera of the electronic device is large. When the paper document 103 is scanned through the large depth of field, since the paper document 103 can be entirely located within the large depth of field, the electronic device can obtain a clear electronic version document 104 as shown in fig. 1 (b) through the camera.

However, when the electronic device is not parallel to the plane in which the object is located, the object of the electronic version obtained by the electronic device is unclear. This results in that the user needs to adjust the position of the electronic device or the object to be photographed, so that the electronic device is parallel to the plane where the object to be photographed is located, resulting in troublesome operation of the user.

That is, when the plane of the electronic device and the object is not parallel (i.e., the plane of the electronic device and the object is at a certain angle), the object may exceed the depth of field range corresponding to the camera, for example, the portion of the object near the upper side or the portion near the lower side may exceed the depth of field range corresponding to the camera. When the photographed object exceeds the depth of field range corresponding to the camera, the electronic device cannot obtain a clear electronic scanning piece corresponding to the part of the photographed object with respect to the depth of field range.

For example, when an electronic device (such as a mobile phone) scans a photographed object by using a document scanning function, the electronic device is not parallel to the plane of the photographed object (i.e., the electronic device forms a certain angle with the plane of the photographed object), and the electronic device cannot obtain a clear electronic document to be schematically illustrated.

After a user opens a document scanning mode on the electronic device, the electronic device may display a document scanning interface 201, as shown in fig. 2 (a), and the document scanning interface 201 may include a scanning control 202. Thereafter, the user may scan (i.e., photograph) the paper document 203 using the electronic device.

When the electronic device is at an angle to the plane of the paper document 203, the user may trigger the scan control 202 so that the electronic device may scan the paper document 203. That is, when the electronic device receives a triggering operation, such as a clicking operation, of the scanning control 202 by the user, the electronic device may scan the paper document 203 in response to obtain document information (such as text information) corresponding to the paper document 203. After the electronic device obtains the document information corresponding to the paper document 203, the electronic device may perform format conversion on the document information corresponding to the paper document 203, such as converting to an electronic version of the document. Thereafter, as shown in (b) of fig. 2, the electronic device may display an electronic version document 204 corresponding to the paper document 203.

When the electronic device forms a certain angle with the plane of the paper document 203, the paper document 203 exceeds the depth of field range corresponding to the camera, for example, the upper part or the lower part of the paper document 203 exceeds the depth of field range corresponding to the camera. When the paper document 203 exceeds the depth of field range corresponding to the camera, the electronic device cannot obtain a clear electronic scan piece corresponding to the part of the content of the photographed object exceeding the depth of field range, that is, as shown in (b) of fig. 2, the electronic device obtains a lower definition of the electronic version document 204.

When the definition of the electronic version document 204 obtained by the electronic device is low, the user needs to adjust the position of the paper document 203 or the electronic device (such as a mobile phone), so that the plane of the paper document 203 is relatively parallel to the electronic device (such as the mobile phone), which results in troublesome operation of the user. Therefore, the paper document 203 can be completely located in the depth of field corresponding to the camera, and the electronic equipment can obtain a clear electronic scanning piece.

In view of the above problems, an embodiment of the present application provides a scanning method applied to an electronic device. The scanning method can include that after the electronic equipment receives the opening operation of a document scanning application program by a user, the electronic equipment can acquire the included angle between the plane where the shot object is located and the electronic equipment. Then, the electronic equipment can determine the target angle required to rotate by the camera according to the included angle between the plane of the shot object and the electronic equipment. Then, the electronic device can rotate the camera by the target angle, so that the shot object can be in the depth of field range corresponding to the camera after the target angle is rotated. After the electronic equipment receives the triggering operation of the user on the scanning control, the electronic equipment can scan the shot object through the camera after rotating the target angle, so that the electronic scanning piece corresponding to the shot object is obtained.

According to the scheme, before the electronic equipment scans the shot object, the electronic equipment can determine the target angle required to rotate by the camera in real time and rotate the camera by the target angle, so that the shot object can be in the depth of field range corresponding to the camera after rotating by the target angle. Therefore, when the electronic device scans the shot object through the camera after the rotation target angle, the shot object can be all in the depth of field range corresponding to the camera after the rotation target angle, so that a clear electronic scanning piece can be obtained. Therefore, when the plane where the electronic equipment and the shot object are located is not parallel, the user needs to adjust the position of the electronic equipment or the shot object, so that the plane where the electronic equipment and the shot object are located is not parallel (even if the shot object can be completely located in the depth of field range corresponding to the camera), the trouble of operation of the user is avoided, and the user experience is improved.

The principle of the scanning method provided in the embodiment of the present application is schematically described below with reference to fig. 3. As shown in fig. 3, the scanning method provided in the embodiment of the present application may include the following procedure.

The electronic equipment firstly enters a document mode, namely after the electronic equipment receives the opening operation of a user on a document scanning application program, the electronic equipment can display a document scanning interface and enter the document mode.

Then, the electronic device can acquire the included angle between the scanning plane and the mobile device. I.e. the electronic device can determine the angle between the plane in which the object is photographed and the electronic device. It should be noted that, the initial state of the camera of the electronic device is parallel to the electronic device, so the included angle between the plane of the photographed object and the electronic device is the included angle between the camera of the electronic device and the plane of the photographed object.

The electronic equipment can acquire the included angle between the scanning plane and the mobile equipmentThen, the electronic device can control the electronic device to control the electronic device according to the acquired included angle between the scanning plane and the mobile device>And determining the target angle theta of the camera required to rotate in real time. That is, the electronic device can control the angle between the acquired scanning plane and the mobile device>And calculating a target angle theta of the camera required to rotate according to the Moire law.

In addition, when calculating the target angle of the camera inclination, the principle of the law of the Mooney can be understood as that the camera is used for the camera is included with the optical axis and the center of the field of view, and the position information of the target object in the image to calculate the inclination angle of the camera relative to the horizontal plane or the vertical plane.

Specifically, the law of Moire can be used for calibration and calibration of cameras to determine the position and attitude of optical elements inside the camera, distortion correction, and the like. The camera is regarded as an ideal pinhole model, and the position and posture information of the target object in the image can be calculated by utilizing the geometric relation in the law of the Moire.

When calculating the inclined target angle of the camera, the position and posture information of the target object in the image need to be determined, and then the inclined angle of the camera relative to the horizontal plane or the vertical plane is calculated by utilizing the geometric relationship in the law of the Moire. This tilt angle may be used to further analyze the position and pose information of the target object or to achieve more accurate image processing and recognition tasks.

After the electronic device determines the target angle θ required to rotate by the camera, the electronic device may push the lens to tilt by the motor corresponding to the camera (i.e., the lens). Therefore, the shot objects can be all in the depth of field range corresponding to the camera after the target angle is rotated.

Then, the electronic apparatus may scan (may also be referred to as photographing) the object to be photographed by the camera after rotating the target angle, so that the electronic apparatus may photograph to complete the document scanning. The electronic equipment can scan the shot object after rotating the target angle to obtain the information of the shot object, and perform format conversion to obtain the electronic scanning piece corresponding to the shot object.

When the electronic device scans the shot object through the camera after rotating the target angle, the shot object can be in the depth of field range corresponding to the camera after rotating the target angle, so that a clear electronic scanning piece corresponding to the shot object can be obtained. Therefore, when the plane where the electronic equipment and the shot object are located is not parallel, the user needs to adjust the position of the electronic equipment or the shot object, so that the plane where the electronic equipment and the shot object are located is not parallel (even if the shot object can be completely located in the depth of field range corresponding to the camera), the trouble of operation of the user is avoided, and the user experience is improved.

The scanning method provided in the embodiment of the present application is described below.

The scanning method provided by the embodiment of the application can be applied to the electronic equipment. In some embodiments, the electronic device may be a cell phone, tablet, handheld computer, personal computer (personal computer, PC), cellular telephone, personal digital assistant (personal digital assistant, PDA), or the like, including an adjustable angle camera, and including a document scanning application.

Therefore, the electronic equipment can determine the included angle between the electronic equipment and the plane of the shot object according to the distance between the electronic equipment and a plurality of detection points between the plane of the shot object. That is, the electronic device determining the included angle between the plane in which the photographed object is located and the electronic device may include the electronic device first acquiring distances between the electronic device and a plurality of detection points in the plane in which the photographed object is located.

That is, the electronic apparatus can detect the distance between the detection point corresponding to the upper edge of the photographed object and the electronic apparatus, and the distance between the detection point corresponding to the vertical line of the electronic apparatus on the plane where the photographed object is located and the electronic apparatus by the DTOF device. And the electronic device may obtain, through measurement, an included angle between a connection line between the detection point corresponding to the upper edge of the object to be shot and the electronic device (in this embodiment, the connection line between the detection point corresponding to the upper edge of the object to be shot and the electronic device may also be referred to as a first connection line), and a connection line between the detection point corresponding to the vertical line of the electronic device on the plane where the object to be shot is located (in this embodiment, the connection line between the detection point corresponding to the vertical line of the electronic device on the plane where the object to be shot is located may also be referred to as a second connection line). In this embodiment of the present application, the included angle between the connection line between the detection point corresponding to the upper edge of the object to be shot and the electronic device and the connection line between the detection point corresponding to the vertical line of the electronic device on the plane where the object to be shot is located may also be referred to as the second included angle. Namely, the second included angle is the included angle between the first connecting line and the second connecting line.

Then, the electronic device may determine, according to a distance between the detection point corresponding to the upper edge of the object to be shot and the electronic device (in this embodiment, a distance between the detection point corresponding to the upper edge of the object to be shot and the electronic device may also be referred to as a second distance), a distance between the detection point corresponding to the vertical line of the electronic device and the electronic device on the plane where the object to be shot is located (in this embodiment, a distance between the detection point corresponding to the vertical line of the electronic device and the electronic device on the plane where the object to be shot is located, and a distance between the detection point corresponding to the upper edge of the object to be shot and the electronic device may also be referred to as a first distance), and an included angle between the electronic device and the plane where the object to be shot is located.

That is, the electronic device may determine the first included angle according to the first distance, the second distance, and the second included angle. When determining the first distance and the second distance, the second distance may be a distance between a detection point corresponding to an upper edge of the object to be shot and a target position on the electronic device, and a distance between a detection point corresponding to a vertical line of the electronic device on a plane where the object to be shot is located and the same target position on the electronic device. The specific position of the target position on the electronic device may be set according to the actual situation, which is not limited in the embodiment of the present application.

The following describes schematically a process of determining an included angle between the electronic device and the plane where the object is photographed by the electronic device according to a distance between the detection point corresponding to the upper edge of the object to be photographed and the electronic device, a distance between the detection point corresponding to the vertical line of the electronic device and the electronic device on the plane where the object to be photographed is located, and an included angle between a connection line between the detection point corresponding to the upper edge of the object to be photographed and the electronic device and a connection line between the detection point corresponding to the vertical line of the electronic device on the plane where the object to be photographed is located, with reference to fig. 7.

As shown in fig. 7, after the electronic device turns on the document scanning function, the electronic device may detect the distance between the detection point 702 corresponding to the upper edge of the plane where the photographed object is located and the electronic device, i.e., H2, and the distance between the detection point 701 corresponding to the vertical line of the electronic device on the plane where the photographed object is located and the electronic device, i.e., H1, through the DTOF device. And the electronic device can obtain the shot through measurementThe included angle between the detection point corresponding to the upper edge of the object and the connecting line of the electronic equipment (namely H2) and the connecting line of the detection point corresponding to the vertical line of the electronic equipment (namely H1) on the plane of the shot object 。

Then, the electronic device may determine the distance between the detection point 702 corresponding to the upper edge of the object to be photographed and the electronic device, i.e. H2, the distance between the detection point corresponding to the vertical line of the electronic device on the plane of the object to be photographed and the electronic device, i.e. H2, and the angle between the connection line (i.e. H2) between the detection point corresponding to the upper edge of the object to be photographed and the electronic device and the connection line (i.e. H1) between the detection point corresponding to the vertical line of the electronic device on the plane of the object to be photographedDetermining an angle between the electronic device and a plane in which the object is located +.>。

H1, H2The relationship between the two can be represented by the following formula one, that is, the electronic device can determine the relationship between H1, H2 and ∈1 through the following formula one (in the embodiment of the present application, the formula one can also be called a first preset formula)>Determining an angle between the electronic device and a plane in which the object is located +.>。

Equation one:；

wherein,in order to obtain an included angle between the electronic equipment and the plane of the shot object, H2 is the distance between the electronic equipment and the detection point corresponding to the upper edge of the plane of the shot object, H1 is the distance between the electronic equipment and the detection point corresponding to the vertical line of the electronic equipment on the plane of the shot object, and H1 is the distance between the electronic equipment and the detection point corresponding to the vertical line of the electronic equipment >The included angle between the connecting line (H2) of the detection point corresponding to the upper edge of the shot object and the electronic equipment and the connecting line (H1) of the detection point corresponding to the vertical line of the electronic equipment on the plane of the shot object.

That is, when the electronic device determines the first included angle according to the first distance, the second distance, and the second included angle, the method may include: the electronic equipment determines a first included angle based on a first preset formula according to the first distance, the second distance and the second included angle.

In other examples, the determining, by the electronic device, an angle between the plane in which the object is photographed and the electronic device may include determining, by the electronic device, an angle between the electronic device and the plane in which the object is photographed based on a phase difference between adjacent Photodiode (PD) points.

In electronic devices, PD points are often used to measure the brightness of ambient light in order to automatically adjust the brightness of the screen, thereby providing a better user experience. The electronic device may include a plurality of PD points.

It should be noted that, in the electronic device, a correspondence relationship (in the embodiment of the present application, may also be referred to as a preset correspondence relationship) between different angles between the electronic device and the plane where the object is located and a phase difference between adjacent PD points of the electronic device may be stored in advance. The phase difference between adjacent PD points, i.e. the difference in phase between different PD points. This difference can be used to measure the image sharpness of the corresponding region scene. When the electronic device includes a plurality of PD points, the adjacent PD points may be any two adjacent PD points of the plurality of PD points, or may be two adjacent PD points preset in the plurality of PD points. That is, when the distance between the electronic device and the plane in which the photographed object is located is fixed and the angle between the electronic device and the plane in which the photographed object is located is different, the phase difference between the adjacent PD points of the electronic device is different.

After the electronic device turns on the document scanning function, the electronic device may acquire a phase difference between adjacent PD points. And then, the electronic equipment can determine the included angle between the electronic equipment and the plane of the shot object according to the phase difference between the adjacent PD points and the corresponding relation between different included angles between the electronic equipment and the plane of the shot object and the phase difference between the adjacent PD points of the electronic equipment.

That is, when the electronic device determines the first included angle (i.e., the included angle between the plane in which the photographed object is located and the electronic device), it may include: the electronic device acquires a phase difference between adjacent photodiode PD points of the electronic device. Then, the electronic device may determine the first included angle according to the phase difference between the adjacent PD points and a preset correspondence.

It should be noted that, in the embodiment of the present application, a specific manner of determining the included angle between the electronic device and the plane where the object is located is not limited, and the included angle between the electronic device and the plane where the object is located may be determined.

After the electronic equipment determines the included angle between the plane where the shot object is located and the electronic equipment, the electronic equipment can determine the target angle required to rotate by the camera of the electronic equipment by the included angle between the plane where the shot object is located and the electronic equipment. So that the electronic device can drive the camera to rotate (which may also be referred to as tilt) a target angle. The target angle is an angle at which the camera of the electronic device can be parallel to the plane in which the object to be photographed is located even after the camera of the electronic device is rotated.

The main plane of the camera of the electronic device refers to the shooting plane of the camera of the electronic device, that is, the front face of the camera of the electronic device. The camera is a main shooting direction of a camera of the electronic equipment and is also a plane where a shot picture is located.

The focal length corresponding to the camera of the electronic device may be a distance between an intersection point of an optical axis corresponding to the camera of the electronic device and the camera, and an intersection point of the optical axis corresponding to the camera of the electronic device and a sensor (may also be referred to as an image plane) for imaging in the electronic device. A sensor for imaging in an electronic device is generally referred to as an image sensor, which is a device capable of converting light into an electronic signal.

That is, the determining, by the electronic device, the target angle at which the camera of the electronic device needs to rotate based on the first included angle may include: the electronic device determines an object distance between the shot object and the electronic device and a focal length corresponding to a camera of the electronic device. And then, the electronic equipment can determine the target angle required to rotate by the camera of the electronic equipment according to the object distance between the shot object and the electronic equipment, the focal length corresponding to the camera of the electronic equipment and the first included angle.

For example, as shown in fig. 8 (a), when the plane in which the object is located is parallel to the electronic apparatus, an intersection point between an optical axis corresponding to a camera (i.e., a lens group) of the electronic apparatus and the plane in which the object is located (i.e., a scanning plane) is an intersection point 801. An intersection point between an optical axis corresponding to a camera (i.e., a lens group) of the electronic device and the camera (i.e., a main plane) is an intersection point 802. An intersection point between an optical axis corresponding to a camera (i.e., lens group) of the electronic device and an intersection point of a sensor (which may also be referred to as an image plane) for imaging is an intersection point 803.

The object distance between the photographed object and the electronic device is the distance between the intersection point of the plane where the photographed object is located and the optical axis corresponding to the camera of the electronic device and the intersection point of the optical axis corresponding to the camera of the electronic device and the camera. That is, the object distance between the subject and the electronic device is the distance between the intersection 801 and the intersection 802.

The focal length corresponding to the camera of the electronic equipment is the distance between the intersection point of the optical axis corresponding to the camera of the electronic equipment and the camera and the intersection point of the optical axis corresponding to the camera of the electronic equipment and the sensor used for imaging in the electronic equipment. I.e. the focal length corresponding to the camera of the electronic device, is the distance between the intersection 802 and the intersection 803.

As another example, in conjunction with (b) in fig. 8, when the plane of the object to be shot is not parallel to the electronic device (i.e., the plane of the object to be shot forms a certain angle with the electronic device), if the camera of the electronic device rotates by the target angle, an intersection point between the optical axis corresponding to the camera (i.e., the lens group) of the electronic device and the plane of the object to be shot (i.e., the scanning plane) is the intersection point 804. An intersection point between an optical axis corresponding to a camera (i.e., a lens group) of the electronic device and the camera (i.e., a main plane) is an intersection point 805. An intersection point between an optical axis corresponding to a camera (i.e., lens group) of the electronic device and an intersection point of a sensor (which may also be referred to as an image plane) for imaging is an intersection point 806.

The object distance between the photographed object and the electronic device is the distance between the intersection point of the plane where the photographed object is located and the optical axis corresponding to the camera of the electronic device and the intersection point of the optical axis corresponding to the camera of the electronic device and the camera. That is, the object distance between the subject and the electronic device is the distance between the intersection 804 and the intersection 805.

The focal length corresponding to the camera of the electronic equipment is the distance between the intersection point of the optical axis corresponding to the camera of the electronic equipment and the camera and the intersection point of the optical axis corresponding to the camera of the electronic equipment and the sensor used for imaging in the electronic equipment. I.e. the focal length corresponding to the camera of the electronic device, is the distance between the intersection point 805 and the intersection point 806.

In some examples, the electronic device may determine the angle between the plane in which the subject is located and the electronic device (i.e.) When determining a target angle (namely theta) required to rotate the camera of the electronic equipment through the law of the Mooney, namely theta, mu, f and ∈>The relationship between them may be a relationship shown in the following formula two. That is, the electronic device may perform the following formula two (the formula two may also be referred to as a second preset formula in the embodiment of the present application)>μ, and f, determining a target angle (i.e., θ) at which the camera of the electronic device is required to rotate.

Formula II:；

wherein,the included angle between the electronic equipment and the plane where the shot object is located is μ the object distance between the shot object and the electronic equipment, f is the focal length corresponding to the camera of the electronic equipment, and θ is the target angle required to rotate the camera of the electronic equipment.

That is, the determining, by the electronic device, the target angle required to rotate the camera of the electronic device according to the object distance between the photographed object and the electronic device, the focal length corresponding to the camera of the electronic device, and the first included angle may include: the electronic equipment determines a target angle based on a second preset formula according to the object distance between the shot object and the electronic equipment, the focal length corresponding to the camera of the electronic equipment and the first included angle.

In some examples, the object distance between the photographed object and the electronic device may be obtained by a sensor in the electronic device that measures the distance. In the embodiment of the present application, the method for acquiring the object distance between the object to be photographed and the electronic device is not limited.

In some examples, the focal length corresponding to the camera of the electronic device is typically a fixed value, and thus the focal length corresponding to the camera of the electronic device may be pre-stored in the electronic device.

S605, the electronic equipment rotates the camera by a target angle.

After the electronic equipment determines the target angle required to rotate by the camera of the electronic equipment according to the included angle between the plane of the shot object and the electronic equipment, the electronic equipment can rotate the camera by the target angle. Therefore, the depth of field range corresponding to the camera of the electronic equipment is changed (namely, the focus corresponding to the camera of the electronic equipment is changed in real time), and the shot objects can be all in the depth of field range corresponding to the camera after the rotation target angle. Because the electronic equipment rotates the camera by the target angle, the camera of the electronic equipment can be in a parallel position with the plane where the shot object is located, after the depth of field range of the camera is changed, the depth of field range corresponding to the changed camera can be fully within the depth of field range corresponding to the camera after the shot object is rotated by the target angle.

Therefore, when the electronic device scans the shot object through the camera after the rotation target angle, the shot object can be all in the depth of field range corresponding to the camera after the rotation target angle, so that a clear electronic scanning piece can be obtained.

It should be noted that, the depth of field corresponding to the camera includes a front depth of field and a rear depth of field. The depth of field range corresponding to the camera of the electronic equipment changes, namely the range sounding changes of the front depth of field and the rear depth of field corresponding to the camera. Because the range of the front depth of field and the rear depth of field corresponding to the camera changes in sounding, the shot object can be in the range of the front depth of field and the rear depth of field corresponding to the camera after the rotation target angle.

In some examples, the electronic device may rotate the camera by a target angle, which may be sent by the electronic device to a driver corresponding to the camera, such that the driver corresponding to the camera may drive the camera by the target angle.

It should be noted that, the corresponding driving (i.e., motor driving) of the camera may include electromagnetic driving, piezoelectric driving, SMA driving, and the like. In the embodiment of the application, the specific type of the driving corresponding to the camera is not limited, and the camera can be driven to rotate by a target angle.

S606, the electronic equipment receives the triggering operation of the user on the scanning control.

After the electronic device rotates the camera by the target angle, the electronic device can receive the triggering operation of the scanning control by the user. Therefore, the electronic equipment can scan the shot object through the camera after rotating the target angle, so that the information of the shot object can be obtained, and the electronic scanning piece of the shot object is obtained.

S607, responding to the triggering operation of the user on the scanning control, and the electronic equipment scans the shot object through the camera after rotating the target angle to acquire the information of the shot object.

When the electronic device receives a triggering operation, such as a clicking operation, of the scanning control by a user, the electronic device can scan the shot object through the camera after rotating the target angle, so that the electronic device can acquire the information of the shot object. The electronic device can obtain the electronic scanning piece of the shot object according to the information of the shot object.

When the object is a document, the information in the object is text information, image information, or form information in the document, and when the object is an image, the information in the object is text information, image information, or form information in the image, and when the object is a form, the information in the object is text information, image information, or form information in the form.

In some examples, after the electronic device rotates the camera by the target angle, the depth of field range corresponding to the camera of the electronic device changes (that is, the focal point corresponding to the camera of the electronic device changes in real time), that is, the electronic device rotates the camera by the target angle, and the camera of the electronic device may be in a parallel position with the plane where the object to be photographed is located, so after the depth of field range of the camera changes, the depth of field range corresponding to the camera after the change is made, and the object to be photographed may be all within the depth of field range corresponding to the camera after the rotation of the target angle. After the electronic equipment rotates the camera by the target angle, the shot object can be completely in the depth of field range corresponding to the camera after rotating the target angle, so that a clear electronic scanning piece can be obtained, and therefore, the electronic equipment can reduce the aperture of the camera, and the definition of the obtained electronic scanning piece can be further improved.

For example, as shown in fig. 9 (a), when the plane in which the object is located (i.e., the focal plane in the drawing) is parallel to the electronic device (i.e., the image plane in the drawing), the depth of field range corresponding to the camera of the electronic device may include a front depth of field and a rear depth of field. The front depth of field is the portion of the depth of field that is near the image plane. The front depth of field is the part far away from the image plane in the depth of field range, and when the focal plane is positioned in the front depth of field and the rear depth of field range, the electronic scanning surface of the shot object formed in the image plane corresponding to the sensor used for imaging in the electronic equipment is clearer.

As another example, as shown in fig. 9 (b), when the plane (i.e., the focal plane in the drawing) where the object is located forms a certain angle with the electronic device (i.e., the image plane in the drawing), the depth of field range corresponding to the camera of the electronic device may include a front depth of field and a rear depth of field. The front depth of field is the portion of the depth of field that is near the image plane. The front depth of field is the part far away from the image plane in the depth of field range, and when the focal plane is positioned in the front depth of field and the rear depth of field range, the electronic scanning surface of the shot object formed in the image plane corresponding to the sensor used for imaging in the electronic equipment is clearer. And the depth of field range corresponding to the camera at this time becomes wedge-shaped, a smaller lens f-number (larger aperture) than that required parallel to the scanning plane can be used for realizing higher definition for the document scanning scene. That is, the electronic device can reduce the aperture of the camera, thereby further improving the definition of the obtained electronic scanning piece.

And S608, the electronic equipment obtains an electronic scanning piece corresponding to the shot object according to the information of the shot object.

After the electronic device obtains the information of the shot object, the electronic device can obtain the electronic scanning piece corresponding to the shot object according to the information of the shot object.

For example, after the electronic device acquires the information in the object, the electronic device may convert the information in the object into an electronic scan piece corresponding to the object. After the electronic scanning piece corresponding to the shot object is obtained, the electronic equipment can display the electronic scanning piece, so that the electronic equipment can be convenient for a user to check and edit.

After the electronic device obtains the electronic scan piece corresponding to the object, the electronic device may display the electronic scan piece corresponding to the object, so that the user may view the electronic scan piece corresponding to the object, or may edit the electronic scan piece corresponding to the object through the electronic device.
