In practical application, the smart pen can be in communication connection with a target device through the communication module F, and based on the communication connection, the smart pen can send the second coordinate to the target device, so that the target device forms the contour of the surface of the object stroked by the pen point based on the second coordinate. The power module E may be configured to supply power to each module inside the smart pen.
For example, the form of the communication connection between the smart pen and the target device may include, but is not limited to, any one of a wired connection and a wireless connection, and the communication connection between the smart pen and the target device in the embodiments of the present application may not be limited. The target device may include any one of a mobile phone, a computer, or a wearable device, and the specific type of the target device may not be limited in this application embodiment.
In practical applications, a touch button 12 is further disposed in the smart pen, and when a first input to the touch button by a user is received, the smart pen may start a drawing mode in response to the first input, and when the first input to the touch button is received again, close the drawing mode in response to the first input.
Referring to fig. 3, a flowchart illustrating steps of a contour collection method according to an embodiment of the present application is shown, where the method specifically includes the following steps:
step 301: and under the condition that the drawing mode is started, acquiring first posture information and first coordinates through the first detection module, and acquiring second posture information through the second detection module.
In the embodiment of the application, the intelligent pen can comprise a drawing mode and a non-drawing mode. In the drawing mode, when the drawing mode is started, in the process that the pen point of the smart pen slides on the surface of the object, first posture information and first coordinates can be acquired through the first detection module a, and second posture information can be acquired through the second detection module B. In the non-drawing mode, the first detection module a and the second detection module B may stop collecting information, and the smart pen may be used as a general smart pen.
In practical application, when a user needs to use the smart pen to acquire a three-dimensional contour of an object, a pen point of the smart pen may be placed on a surface of the object, and then a drawing mode of the smart pen is started. After the drawing mode is initiated, the pen tip of the smart pen may be stroked across the surface of the object to capture pose information and coordinate information for as many contour points on the surface of the object as possible. In order to be able to form as complete a contour as possible, the tip of the smart pen should be moved across every surface of the object as far as possible.
Specifically, the first detection module a and the second detection module B should collect coordinate information and attitude information of different contour points of each portion of the object according to a preset frequency. The preset frequency may be a time interval of microsecond level, for example, 3 microseconds, 4 microseconds, or 6 microseconds, and the like.
Step 302: and determining a second coordinate of the pen point under the space coordinate according to the first coordinate, the distance between the pen point and the first detection module, the first posture information and the second posture information.
In the embodiment of the application, in the process of using the intelligent pen to stroke on the surface of the object, since the pen holding posture changes, the position of the second detection module B at the pen point relative to the first detection module a also changes correspondingly in the spatial coordinate system.
In practical application, in order to obtain the second coordinate of the pen tip under the spatial coordinate, firstly, a displacement variable of the second detection module B at the pen tip relative to the first detection module a at different acquisition times needs to be determined according to the distance H between the pen tip and the first detection module, the first posture information and the second posture information. And then, according to the first detection module A and the displacement variable, determining a second coordinate of the pen point under the space coordinate.
Specifically, since the pen tip is drawn across the surface of the object, the second coordinate of the pen tip is the same as the coordinate of each contour point on the surface of the object, and the second coordinate is acquired as many as possible by drawing the pen tip across as many contour points on the surface of the object, so that the contour of the surface of the object can be formed by the coordinate information of as many contour points as possible.
Step 303: sending the second coordinates to a target device to enable the target device to display the outline of the surface of the object scratched by the pen tip; wherein the contour is derived based on a spatial trajectory formed by the second coordinates.
In this application embodiment, because the smart pen with communication connection between the target device, consequently, based on communication connection, the smart pen can with the second coordinate of nib sends to the target device. Since the pen tip is drawn across the surface of the object, the second coordinate of the pen tip is the same as the coordinate of each contour point on the surface of the object, and therefore, after the target device receives the second coordinate of the pen tip, a spatial trajectory drawn by the pen tip can be formed according to the second coordinate, and the contour of the surface of the object drawn by the pen tip can be formed according to the spatial trajectory. Meanwhile, the outline can be displayed, so that a user can directly know the drawing condition of the outline of the object.
In practical applications, the smart pen may send the second coordinate of the pen tip to the target device according to a certain frequency, or send the second coordinate of the pen tip to the target device after all contour points of the surface of the object are collected, which is not limited in this embodiment of the present application. In addition, the target device may synchronously display the forming process of the contour of the object in the process of forming the contour of the surface of the object, so that a user can intuitively know the forming progress of the contour of the object, and the forming progress may also be displayed after the complete contour is formed, which is not limited in the embodiment of the present application.
In summary, the contour acquisition method according to the embodiment of the present application may include at least the following advantages:
in the embodiment of the application, when the smart pen starts a drawing mode, the first detection module acquires first posture information and a first coordinate, and the second detection module acquires second posture information; determining a second coordinate of the pen point under the space coordinate according to the first coordinate, the distance between the pen point and the first detection module, the first posture information and the second posture information; sending the first coordinates to a target device to enable the target device to display the outline of the surface of the object scratched by the pen point; wherein the contour is derived based on a spatial trajectory formed by the second coordinates. Therefore, the pen point of the intelligent pen can be used for forming the outline of the object by scratching the surface of the object, and the intelligent pen is simple in method, simple in structure and low in cost. Moreover, the intelligent pen is small in size and convenient to carry, so that the intelligent pen can meet the requirement of a user for collecting the outline of an object in different scenes, and the use experience of the user is greatly enriched.
Referring to fig. 4, a flowchart illustrating steps of another contour acquisition method according to an embodiment of the present application is shown, and as shown in fig. 4, the method may specifically include:
step 401: a first input is received for a touch button.
In the embodiment of the application, a touch button is further arranged in the smart pen, the touch button can be used for receiving a first input, and the first input can be used for starting or exiting a drawing mode of the smart pen.
For example, the touch button may be disposed at a top of the smart pen, or may be disposed at a side of the smart pen, and the like. The touch button can be triggered in a pressing and rotating mode, and the triggering mode of the touch button in the embodiment of the application is not limited.
Step 402: in response to the first input, a drawing mode is enabled.
In an embodiment of the application, the smart pen may initiate a drawing mode in response to the first input.
Step 403: and under the condition that the drawing mode is started, acquiring first posture information and first coordinates through the first detection module, and acquiring second posture information through the second detection module.
In the embodiment of the present application, the specific implementation process of step 403 is the same as that of step 301 in the foregoing embodiment, and is not described herein again.
Step 404: and determining a second coordinate of the pen point under the space coordinate according to the first coordinate, the distance between the pen point and the first detection module, the first posture information and the second posture information.
In an optional embodiment of the present application, the method of determining the second coordinate of the pen tip in the spatial coordinate system may comprise the sub-steps of:
substep S11: and determining a displacement variable of the pen point relative to the first detection module according to the distance between the pen point and the first detection module, the first posture information and the second posture information.
In the embodiment of the application, in the process of using the intelligent pen to stroke on the surface of the object, since the pen holding posture changes, the position of the second detection module B at the pen point relative to the first detection module a also changes correspondingly in the spatial coordinate system. Therefore, the displacement variation of the second detection module B at the pen point relative to the first detection module a at different times of acquisition needs to be determined.
In an alternative embodiment of the present application, the displacement variable of the second detection module B relative to the first detection module a at the pen tip may be determined according to the following method:
first, a polar angle and an azimuth angle of the pen tip relative to the second detection module are determined according to the first posture information and the second posture information.
In practical applications, the first posture information may include an angular velocity, a magnetic field strength and a direction of the first detection module a, and the second posture information may include an angular velocity, a magnetic field strength and a direction of the second detection module B. With the first detection module A as an origin, the polar angle of the second detection module B relative to the first detection module A can be calculated according to the first attitude information and the second attitude information
And an azimuth angle λ.
Then, according to the distance between the pen tip and the first detection module, the polar angle and the azimuth angle, the displacement variable of the pen tip relative to the second detection module is determined.
In practical applications, the distance H between the pen tip and the first detection module a in the space coordinate may be stored in the memory D of the smart pen in advance. According to the distance H, the polar angle of the second detection module B relative to the first detection module A
And an azimuth angle λ, the displacement variables σ Lx, σ Ly, σ Lz of the second detection module B of the pen tip relative to the first detection module a can be determined:
substep S12: and determining a second coordinate of the pen point under the space coordinate according to the first coordinate and the displacement variable.
In the embodiment of the present application, since the first coordinates (Lx, Ly, Lz) of the first detection module a are already determined in step 403, the second coordinates (Lx + σ Lx, Ly + σ Ly, Lz + σ Lz) of the pen tip in the spatial coordinates can be determined according to the first coordinates (Lx, Ly, Lz) of the first detection module a and the displacement variables σ Lx, σ Ly, σ Lz of the second detection module B relative to the first detection module a.
Specifically, since the pen tip is drawn across the surface of the object, the second coordinate of the pen tip is the same as the coordinate of each contour point on the surface of the object, and the second coordinate is acquired as many as possible by drawing the pen tip across as many contour points on the surface of the object, so that the contour of the surface of the object can be formed by the coordinate information of as many contour points as possible.
Step 405: sending the second coordinates to a target device to enable the target device to display the outline of the surface of the object scratched by the pen tip; wherein the contour is derived based on a spatial trajectory formed by the second coordinates.
In the embodiment of the present application, the specific implementation process of step 405 is the same as that in step 303 in the foregoing embodiment, and is not described herein again.
Step 406: under the condition that a contour completion instruction sent by the target equipment is received, the communication connection between the intelligent pen and the target equipment is interrupted; wherein the contour completion instruction is determined by the target device after forming the contour of the object surface.
In practical applications, the target device may generate a contour completing instruction after forming the contour of the object. The contour completing instruction may be automatically generated after the target device scans the contour, or may be generated according to an operation of a user on the target device. In practical applications, after the target device generates the contour completing command, the target device may send the contour completing command to the smart pen.
In the embodiment of the application, the intelligent pen can interrupt the communication connection between the intelligent pen and the target device when receiving the contour completion instruction sent by the target device, and stops sending the nib to the target device, wherein the second coordinate of the nib under the space coordinate system is used for avoiding the repeated drawing of the target device on the contour of the object, and the intelligent pen and the electric quantity of the target device can be saved.
Step 407: in a case where the first input for the touch button is received again, the drawing mode is turned off in response to the first input.
In this embodiment of the application, when the smart pen receives the first input to the touch button again, the drawing mode may be closed in response to the first input, so that the smart pen may operate in a non-drawing mode, and switching between the drawing mode and the non-drawing mode is achieved.
For example, in the case that the smart pen is operated in the non-drawing mode, the smart pen may be used to input instructions to a computer screen, a mobile device, a drawing board, or the like having a touch screen, and a user may select a file or a drawing by clicking on the touch screen with the touch pen.
In summary, the contour acquisition method according to the embodiment of the present application may include at least the following advantages:
in the embodiment of the application, under the condition that the intelligent pen starts the drawing mode, the pen point of the intelligent pen is used for scratching the surface of the object to form the outline of the object, and the method is simple, simple in structure and low in cost. Moreover, the intelligent pen is small in size and convenient to carry, so that the intelligent pen can meet the requirement of a user for collecting the outline of an object in different scenes, and the use experience of the user is greatly enriched. Moreover, the intelligent pen can respond to the first input aiming at the touch button, so that the switching between the drawing mode and the non-drawing mode is realized, and the functions of the intelligent pen are enriched.
