[0052] The camera module of the scanning pen will produce distortion phenomenon at the edge of shooting, such as Figure 1 As shown, a and b respectively represent the lengths of two opposite sides of the edge of the shooting image of the object by the camera module. In the case that the lens face of the camera module and the shooting object are parallel, that is, the angle β between the normal of the shooting direction of the camera module and the plane of the shooting object is 90°, the scanning range is a regular square in the horizontal plane, and the lengths of the opposite sides of the square are equal and parallel, that is, a = b; as shown, Figure 2 In the case that the lens face of the camera module and the shooting object are not parallel, that is, the angle β between the normal of the shooting direction of the camera module and the plane of the shooting object is not 90°, the scanning range is a trapezoid in the horizontal plane, and the lengths of the two parallel sides are not equal, that is, a ≠ b, and the distortion is more serious than that when β = 90°.
[0053] Therefore, as shown, Figure 3 The embodiment provides a scanning pen, which comprises a shell 1, an angle sensor 2, a camera module 3, a rotary driving member 4 and a controller 12.
[0054] The shell 1 has a receiving cavity, and the controller 12 is arranged in the receiving cavity.
[0055] The rotary driving member 4 is fixedly installed on the shell 1, and the driving end of the rotary driving member 4 is in transmission connection with the camera module 3, so that the camera module 3 can be installed in the receiving cavity in a tilting manner. An end of the shell 1 is provided with a first light transmission hole, and the camera module 3 scans the content on the medium to be scanned through the first light transmission hole.
[0056] The camera module 3, the angle sensor 2 and the rotary driving member 4 are electrically connected with the controller 12.
[0057] The angle sensor 2 is fixed to the camera module 3 and is used for collecting the inclination angle of the lens face of the camera module 3 relative to the plane of the medium to be scanned. The controller 12 is used for controlling the rotary driving member 4 to drive the camera module 3 to rotate based on the inclination angle, so that the lens face of the camera module 3 is parallel to the plane of the medium to be scanned.
[0058] As shown in the drawings, Figure 4 and Figure 5 The shell 1 of the scanning pen comprises a front shell 101, a rear shell 102 and a panel 103. The front shell 101 and the rear shell 102 are buckled to form a receiving cavity, and the panel 103 is arranged on the front shell 101. The panel 103 is provided with a perspective window for a user to observe the content on the medium to be scanned. One end of the rear shell 102 is provided with a lens 104, and the lens 104 is arranged at the first light transmission hole and seals the camera module 3, which can prevent dust and does not affect the scanning function of the camera module 3.
[0059] The controller 12 is installed in the accommodating cavity, and the camera module 3 is installed at one end of the scanning pen for scanning. The camera module 3 and the angle sensor 2 rotate synchronously, and the angle sensor 2 can collect the tilt angle of the lens face of the camera module 3 relative to the plane where the medium to be scanned is located in real time. Based on the habits of different users in holding the scanning pen, the angle between the length direction of the shell 1 and the plane where the medium to be scanned is located is not fixed during scanning, and the common range is between 45° and 70°. With the change of the angle between the shell 1 and the medium to be scanned, the angle sensor 2 feeds back the angle information collected in real time to the controller 12, and the controller 12 controls the rotary driving member 4 to drive the camera module 3 to rotate, so as to adjust the angle between the lens face of the camera module 3 and the plane where the medium to be scanned is located, and ensure that the lens face of the camera module 3 is always parallel to the plane where the medium to be scanned is located, so as to minimize the distortion phenomenon. Further, no matter how the user holds the scanning pen, the tilt angle of the camera module 3 relative to the plane where the medium to be scanned is located can be automatically adjusted, so as to ensure the scanning precision.
[0060] As shown in Figure 6 , the angle α1 between the length direction of the shell 1 and the plane where the medium to be scanned is located is 90°, and the angle β1 between the perpendicular of the lens face of the camera module 3 and the plane where the medium to be scanned is located is 90°, that is, the lens face of the camera module 3 is parallel to the plane where the medium to be scanned is located.
[0061] As shown in Figure 7 , the angle α2 between the length direction of the shell 1 and the plane where the medium to be scanned is located is 60°, and the angle β2 between the perpendicular of the lens face of the camera module 3 and the plane where the medium to be scanned is located is still 90°, that is, the lens face of the camera module 3 is still parallel to the plane where the medium to be scanned is located. Although the holding angle of the user for the scanning pen changes from α1 to α2, the lens face of the camera module 3 is always parallel to the plane where the medium to be scanned is located.
[0062] Generally, the plane where the medium to be scanned is located is a horizontal plane. The angle sensor 2 is an inclination sensor, which can detect the angle between the camera module 3 and the horizontal plane, so as to obtain the inclination angle of the lens face of the camera module 3 relative to the plane where the medium to be scanned is located.
[0063] In an alternative embodiment, the controller comprises a circuit board, a processor 5, a first connector and a second connector, the processor 5, the first connector and the second connector are all mounted on the circuit board.

One end of the second flexible circuit board 17 is electrically connected with the second connector 19, and the other end is electrically connected with the rotary driving member 4. The rotary driving member 4 is a steering wheel or other driving structure. When scanning, the controller 12 controls the lens face of the camera module to keep parallel with the plane where the medium to be scanned is located according to the information collected by the angle sensor.
[0064] The camera module 3 is assembled on the rear shell 102, and the circuit board has a avoiding opening for providing an avoiding position for the camera module 3.
[0065] The second flexible circuit board 17 is arranged in a bent type. One end of the second flexible circuit board 17 passes through the gap between the circuit board and the shell 1 to extend to the second connector 19, and the other end of the second flexible circuit board 17 is welded on the feed point of the rotary driving member 4. Of course, the circuit board can also be provided with a wire passing hole, and the second flexible circuit board 17 is arranged in the wire passing hole to connect the rotary driving member 4 and the second connector 19.
[0066] The scanning pen provided by the utility model has the advantages that the camera module 3, the angle sensor 2, the rotary driving member 4 and the controller 12 are arranged in the shell 1, the camera module 3 and the angle sensor 2 are fixedly and reversibly installed in the accommodating cavity, the angle between the lens face of the camera module 3 and the plane where the medium to be scanned is located is collected in real time by the angle sensor 2, when the inclination angle between the lens face of the camera module 3 and the plane where the medium to be scanned is located is not zero, the controller 12 controls the rotary driving member 4 to drive the camera module 3 to rotate, so that the lens face of the camera module 3 is adjusted to be parallel to the medium to be scanned, based on the real-time collection of the angle sensor 2 and the synchronous rotation of the camera module 3, no matter what angle the user holds the scanning pen, the parallel arrangement of the lens face of the camera module 3 and the plane where the medium to be scanned is located can be ensured, so that the distortion degree of the scanning image is the lowest, and the scanning precision of the scanning pen is improved.
