[0021] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the accompanying drawings in the present application. Obviously, the described embodiments are only some, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall into the protection scope of the present application.

[0022] The structure of the scanning dictionary pen of the present application will be described below with reference to the accompanying drawings. Figures 1-2 The structure of the scanning dictionary pen of the present application will be described below with reference to the accompanying drawings.

[0023] The present application provides a scanning dictionary pen, as shown in Figure 1 and Figure 2 , which comprises a pen body 10, a scanning head 20, a controller and a first camera 30. The scanning head 20 is arranged at the first end of the pen body 10, and the first camera 30 is rotatably installed at the second end of the pen body 10. The controller is installed in the pen body 10. The controller is used to control the movement of the first camera 30 according to the posture of the pen body 10.

[0024] If the user holds the pen body 10 and makes the scanning head 20 contact with the surface of the scanning medium, at this time, the included angle between the pen body 10 and the surface of the scanning medium is within the first threshold range, in this case, the first camera 30 acquires an initial image, and according to the initial image, it is judged whether the scanning head 20 is at the corner of the scanning medium. If it is at the corner, the first camera 30 is controlled to rotate to scan the content of the entire surface of the scanning medium. Compared with the line-by-line scanning mode, it is more efficient to acquire the text content of the entire surface of the scanning medium by the first camera 30. If it is not at the corner, the scanning head 20 is taken as the tracking target to follow the scanning head 20 to move and continuously acquire the text image in the field of view, and the scanning result of the target text is corrected by comparing the text information acquired by the first camera 30 and the text information acquired by the scanning head 20, and at the same time, the context information of the target text is acquired by the first camera 30, so that the translation result is more accurate. If the user holds the pen body 10 to make the pen body 10 substantially parallel to the surface of the scanning medium, that is, the included angle between the pen body 10 and the surface of the scanning medium is within the second threshold range, at this time, the first camera 30 is controlled to scan the text information of the entire surface of the scanning medium according to the preset path.

[0025] The first threshold range is the inclination range of the pen body 10 when the user holds the pen body 10, for example, 65°-70°, and the second threshold range refers to the angle range when the pen body 10 is substantially parallel to the surface of the scanning medium, for example, 0°-20°.

[0026] In an alternative embodiment, the first camera 30 is rotatable along the length direction of the pen body 10 and rotatable along the width direction of the pen body 10. Thus, the first camera 30 can be rotated up and down and rotated left and right when the scanning dictionary pen is in the holding posture. In yet another alternative embodiment, the first camera 30 is rotatable along the X direction, the Y direction and the Z direction, so that the first camera 30 can be rotated in three-dimensional directions relative to the pen body 10. It should be noted that the width direction of the pen body 10 refers to the direction in which the scanning dictionary pen extends left and right as shown in the figure. Figure 1 The thickness direction of the pen body 10 refers to the direction in which the scanning dictionary pen extends front and back as shown in the figure. The length direction, the width direction and the thickness direction appearing hereinafter refer to the same. Figure 1

[0027] The scanning dictionary pen provided by the embodiment of the present application has the first camera 30 installed at the second end of the pen body 10, and the first camera 30 is rotatable relative to the pen body 10, so that the first camera 30 is controlled to move by the controller according to the posture of the pen body 10, the first camera 30 automatically tracks the movement of the scanning head 20 to acquire the text image or automatically acquires the text image of the entire surface of the scanning medium, so that the scanning result of the scanning head 20 can be corrected, and the text information of the entire surface of the scanning medium can be quickly acquired.

[0028] In an alternative embodiment, the pen body 10 is provided with a posture sensor, and the controller is in communication connection with the posture sensor, and the controller controls the movement of the first camera 30 based on the posture information transmitted by the posture sensor.

[0029] In an alternative embodiment, the pen body 10 is provided with a posture sensor, and the controller is in communication connection with the posture sensor, and the controller controls the movement of the first camera 30 based on the posture information transmitted by the posture sensor.

[0030] The scanning dictionary pen provided by the embodiment of the present application determines the posture of the pen body 10 by the posture sensor provided on the pen body 10, so as to control the movement of the first camera 30 according to different postures of the pen body 10, and improve the scanning effect of the scanning dictionary pen.

[0031] In a specific embodiment, the scanning dictionary pen further comprises a first connecting arm 40 and a second connecting arm 50. The first connecting arm 40 is rotatably installed at the second end of the pen body 10 along a first direction, the second connecting arm 50 is rotatably installed at the first connecting arm 40 along a second direction, and the first camera 30 is installed at the second connecting arm 50. The first direction and the second direction are perpendicular.

[0032] ​Specifically, the first connecting arm 40 is rotatably mounted on the second end of the pen body 10 along the length direction of the pen body 10, and the first camera 30 is rotatably mounted on the second connecting arm 50 along the width direction of the pen body 10. It should be noted that the first connecting arm 40 can also be rotatably mounted on the pen body 10 along the width direction of the pen body 10, as long as the first camera 30 can rotate freely in two-dimensional space.

[0033] In an embodiment, the scanning dictionary pen further comprises a support rotatably mounted on the pen body 10 along a first direction, and the first camera 30 is rotatably mounted on the support along a second direction. Correspondingly, the first camera 30 has rotational freedom in the first direction and the second direction. The first direction is along the length direction of the pen body 10, and the second direction is along the width direction of the pen body 10. When the pen body 10 is erected, the first camera 30 can rotate horizontally and vertically. It can be understood that the rotation angle of the first camera 30 along the first direction and the second direction can be 180° to achieve a wide range of rotation.

[0034] In an optional embodiment, the first camera 30 is fixedly connected with the second connecting arm 50. Correspondingly, the first camera 30 can rotate in two directions with the first connecting arm 40 and the second connecting arm 50. In another optional embodiment, the first camera 30 is rotatably connected with the second connecting arm 50. For example, a third driving mechanism is arranged at the port of the second connecting arm 50, and the driving end of the third driving mechanism is connected with the first camera 30 to drive the first camera 30 to rotate relative to the second connecting arm 50. Optionally, the rotation direction of the first camera 30 relative to the pen body 10, the rotation direction of the first connecting arm 40 relative to the pen body 10, and the rotation direction of the second connecting arm 50 relative to the pen body 10 are perpendicular to each other, so as to realize the free rotation of the first camera 30 in three-dimensional space. Of course, the rotation direction of the first camera 30 relative to the pen body 10 can be consistent with the rotation direction of the second connecting arm 50 relative to the pen body, so as to expand the rotation angle of the second connecting arm 50.

[0035] The second end of the pen body 10 is provided with a first driving mechanism 60, and the driving end of the first driving mechanism 60 is connected with the first connecting arm 40. The controller is in communication connection with the first driving mechanism 60, and under the driving of the first driving mechanism 60, the first connecting arm 40 rotates along the length direction of the pen body 10 as the axis.

[0036] The first driving mechanism 60 is a driving motor fixedly mounted on the second end of the pen body 10, and the first connecting arm 40 is connected with the motor shaft of the driving motor. Under the action of the first driving mechanism 60, the driving motor drives the first connecting arm 40 to rotate. The driving motor adopts a micro motor to reduce the space occupation. The controller controls the first driving mechanism 60 to drive the first camera 30 to move left and right according to the posture of the pen body 10.

[0037] Optionally, the first connecting arm 40 is L-shaped. The vertical arm of the L-shaped first connecting arm 40 is rotatably connected with the second connecting arm 50, and the driving shaft of the first driving mechanism 60 is fixedly connected with the horizontal arm of the L-shaped first connecting arm 40. In addition, the first connecting arm 40 can also be a holder, and the cross section of the holder is consistent with the cross section of the pen body 10. The holder is rotatably installed on the pen body 10 by the first driving mechanism 60.

[0038] As shown in Figure 2 , the first connecting arm 40 is provided with a second driving mechanism 70, and the driving end of the second driving mechanism 70 is connected with the second connecting arm 50. The controller is in communication connection with the second driving mechanism 70.

[0039] Specifically, the second driving mechanism 70 is a micro motor, the motor shaft of the micro motor is connected with the second connecting arm 50, and the shell of the micro motor is fixed on the first connecting arm 40. As shown in Figure 2 , the micro motor is arranged at the end of the first connecting arm 40 away from the pen body 10, and the shell of the micro motor is arranged at the vertical arm end of the L-shaped first connecting arm 40. Under the driving of the second driving mechanism 70, the second connecting arm 50 rotates with the width direction of the pen body 10 as the axis.

[0040] As shown in Figure 2 , the second connecting arm 50 is U-shaped, and the opposite ends of the first camera 30 are connected with the opposite sides of the second connecting arm 50, respectively.

[0041] The second connecting arm 50 is a U-shaped bracket, the bottom of the U-shaped bracket is connected with the driving shaft of the second driving mechanism 70, and the first camera 30 is arranged at the opening of the U-shaped bracket and the two ends of the U-shaped bracket are connected with the first camera 30, respectively. In addition, the second connecting arm 50 can be a sphere, the second camera is installed in the sphere, and the bottom of the sphere is connected with the driving end of the second driving mechanism 70.

[0042] In an embodiment, the first camera 30 is fixedly connected with the opposite sides of the U-shaped bracket, so as to clamp and fix the first camera 30 on the second connecting arm 50. In another embodiment, a third driving mechanism is arranged at one side or both sides of the U-shaped bracket, the driving end of the third driving mechanism is connected with the first camera 30. Under the action of the third driving mechanism, the first camera 30 can rotate relative to the U-shaped bracket. The scanning dictionary pen provided by the embodiment of the present application is provided with a U-shaped second connecting arm 50, and the opposite sides of the first camera 30 are connected with the second connecting arm 50, respectively, so that the first camera 30 is located at the opening of the U-shaped bracket. Compared with the structure in which the camera is installed in a closed structure, the U-shaped second connecting arm 50 can effectively avoid that the heat of the first camera 30 is gathered in the closed structure.

[0043] Optionally, the pen body 10 is provided with a display screen, and the display screen is used to display the scanning result of the scanning head and / or the first camera.

[0044] Optionally, the pen body 10 is provided with a scanning switch, and the scanning switch is in communication connection with the main control board, and the scanning switch is used to start the scanning head 20 and / or the first camera 30 to start the scanning mode under the triggering condition.

[0045] In an embodiment, the scanning switch is pressed, and the scanning head 20 and the first camera 30 are started to start the scanning mode. The controller controls the operation of the first camera 30 according to the posture of the pen body 10. Specifically, if the included angle between the pen body 10 and the scanning medium surface is within a first threshold range, the operation of the first camera 30 is determined according to the initial image captured by the first camera 30. For example, when the scanning head 20 moves along with the hand to scan the text information line by line, the first camera 30 automatically follows the scanning head 20 under the action of the controller to synchronously acquire the text information. When the scanning head 20 is at the edge of the scanning medium surface, the first camera 30 is controlled to scan the text information on the entire scanning medium surface. If the included angle between the pen body 10 and the scanning medium surface is within a second threshold range, the first camera 30 is controlled to move to scan the text information on the entire scanning medium surface.

[0046] In another embodiment, the pen body 10 is provided with a scanning switch, and the scanning switch is used to separately control the first camera 30 to start the scanning mode. When it is necessary to scan the text information on the entire scanning medium surface or it is necessary for the first camera 30 to assist the scanning head 20 to scan, the scanning switch is pressed to start the first camera 30. After the scanning is completed, the scanning switch is pressed again to turn off the first camera 30. The scanning head 20 triggers the scanning mode by contacting the scanning medium surface or starts the scanning mode by another scanning switch. In this way, the first camera 30 and the scanning head 20 are independently triggered to start the scanning mode, so as to reduce the energy consumption.

[0047] The scanning head 20 in the present application comprises a second camera, and the second camera is installed at the first end of the pen body 10, and the second camera is used to acquire the text image of the scanning area when the scanning pen is scanned over the scanning medium surface.

[0048] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
