Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0031] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0032] In some modeling software such as painting software and writing input software, it is often necessary to use a mouse for input. However, the current mouse has low precision and cannot meet the software operation requirements of modeling software that require extremely high input precision. In addition, the current mouse often requires a mouse pad when in use, and is large in size, which greatly reduces the convenience of use.

[0033] Based on this, in order to improve the accuracy and convenience of the mouse, and to expand the functions and usage scope of the mouse, the present invention provides a pen-type electronic mouse. The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings.

[0034] Figure 1 1 is a schematic diagram of the structure of a pen-type electronic mouse provided by an embodiment of the present invention. FIG. A is a schematic diagram of the overall structure of the pen-type electronic mouse, and FIG. B is a schematic diagram of the internal structure of the pen-type electronic mouse. Figure 1 As shown, the mouse includes: a main body 11, a button module 12, a ball 13, a roller 14, an image acquisition module 15, a signal processing module 16, a power supply module 17 and a communication module ( Figure 1 not shown).

[0035] The main body 11 is pen-shaped and hollow inside. Specifically, the pen holder of the main body 11 can be a cylindrical pen holder structure or a pen holder structure of other shapes, for example, a hexagonal pyramid pen holder structure.

[0036] The surface of the ball 13 has a pattern, and the ball 13 is arranged at the tip of the main body 11. Specifically, the surface of the ball 13 may have a groove pattern. Compared with a plane pattern, a three-dimensional groove pattern is more wear-resistant, which is conducive to increasing the service life of the mouse.

[0037] The button module 12 and the roller 14 are arranged on the side wall of the pen holder of the main body 11, and the top is exposed, so that the user can click the button module 12 and scroll the roller 14. The button module 12 includes a first button and a second button, the first button is the left button of the mouse, used for left clicking, and the second button is the right button of the mouse, used for right clicking.

[0038] The first button and the second button can be arranged at one end of the main body 11 close to the pen tip, and the first button can be arranged opposite to the second button. This conforms to the user's pen holding habit and facilitates the user to click the first button and the second button.

[0039] The scroll wheel 14 can be arranged at one end near the top of the main body 11 and can be located just above the first button, so that when the user holds the mouse, the thumb can easily switch between the first button and the scroll wheel 14, making it convenient for the user to use. When the user rolls the scroll wheel 14, the corresponding function of the existing mouse wheel is realized, for example, the current page is scrolled.

[0040] The image acquisition module 15, the signal processing module 16 and the power supply module 17 are arranged in the internal hollow structure of the main body 11. In this way, the image acquisition module 15, the signal processing module 16 and the power supply module 17 can be prevented from being damaged due to external related damage, thereby extending the service life of the mouse.

[0041] The image acquisition module 15 is provided with a microscope eyepiece 151 and a photoelectric sensor 152. The image acquisition module 15 receives the light reflected by the ball 13 through the microscope eyepiece 151, generates a surface image of the ball through the photoelectric sensor 152, and sends the surface image of the ball to the signal processing module 16. The microscope eyepiece 151 has a magnifying effect, and can magnify the ball under the viewing angle of the photoelectric sensor 15, so that even a small rotation of the ball can be identified, thereby improving the accuracy of the mouse.

[0042] The signal processing module 16 is used to process the ball surface image based on a preset super sampling algorithm, a fine error function calibration technique and a spherical image displacement calculation to obtain a processed ball surface image. The preset super sampling algorithm and the fine error function calibration technique can improve the imaging quality, and the spherical image displacement calculation is conducive to more accurately judging the rolling of the ball in the two-dimensional direction.

[0043] Subsequently, the signal processing module 16 uses the processed ball surface image as input to calculate the displacement between the corresponding two frames of images. The strategy for calculating the displacement may be to shoot 1500 frames of images per second, the resolution of each frame of image may be 100×100, and use the graph cross-correlation algorithm to calculate the jump displacement between each frame of image and input it to the computer.

[0044] It should be noted that the preset super-sampling algorithm, fine error function calibration technology and spherical map displacement calculation are all algorithms in the prior art.

[0045] The preset super-sampling algorithm can be the super-sampling algorithm mentioned in the article "Xue H, Shang M, Zhang Z, et al. Hyper-Sampling Imaging by Measurement of Intra-Pixel Quantum Efficiency Using Steady Wave Field [J]. Laser & Photonics Reviews, 2024: 2401306.". The algorithm relies on steady-state low-frequency laser interference fringes to accurately solve the quantum efficiency distribution within the sensor pixel. This step is like building a solid foundation for subsequent image processing. On this basis, the algorithm deeply explores the intrinsic relationship between the captured image, quantum efficiency, and the true value of the light field, and cleverly uses the least squares algorithm for fitting calculations. In this way, a high-quality super-resolution image of the captured target can be accurately solved. Compared with traditional image algorithms and deep learning methods, this algorithm has significant advantages. It can not only stably improve image quality and resolution, but more importantly, it does not introduce false information. On the contrary, it can add high-frequency physical information, which does not just stop at improving the visual effect, but enhances the real information contained in the image from a physical level, providing a more reliable and accurate data basis for subsequent image-based analysis and applications.

[0046] The principle of the fine error function calibration technique is explained below.

[0047] Figure 2 This is a schematic diagram of the principle of fine error function calibration technology. Figure 2 As shown, the grayscale value I of the pixel pixel (m,n) located in the mth row and nth column on the image sensor m,n and the image sensor readout circuit gain G, exposure accumulation light number S m,n And the number of photogenerated electrons N in this pixel m,n The relationship is:

[0048]

[0049] Among them, am,n and b m,n and c m,n They represent the dark current coefficient, linear coefficient and nonlinear coefficient of the electrons generated by pixel (m,n) under light. (i,j) represents the horizontal and vertical coordinate values ​​within the pixel, and i = 1, 2, 3, ... k, j = 1, 2, 3, ... k. [a m,n (i,j), b m,n (i,j), c m,n (i,j)] represents the response tensor at the sub-pixel level of pixel(m,n).

[0050] Before using the image sensor, the sub-pixel level response tensor is solved using laser interference fringes: First, the surface of the built-in image sensor is scanned using dynamic laser interference fringes, and the overdetermined equation group (2) is established by capturing the relationship between the grayscale value I and the true value S of the interference light field, where I z,m,n Represents the grayscale value of pixel (m,n) on the z-th frame image. m and n are the two-dimensional horizontal and vertical coordinates in pixels on the sensor or image:

[0051]

[0052] The sensor’s sub-pixel-level response tensor [a, b, c] is obtained through formula (2). When using the sensor, [a, b, c] is used in reverse to solve the high-quality super-resolution image [S] of the captured target:

[0053]

[0054] It should be noted that in formula (2), I and S are known quantities, and in formula (3), I and [a, b, c] are known quantities.

[0055] The principle of spherical map displacement calculation is explained below.

[0056] Figure 3 This is a schematic diagram of the principle of spherical displacement calculation. Figure 3 As shown in the figure, the top view of the ball is taken through the microscope eyepiece (i.e., L figure), R is the ball radius, O represents the image center, which is also the center of the ball, L represents the distance from the projection of any point on the ball surface in L figure to O point, and S represents the rolling path on the spherical surface actually represented by the point at a distance L from the image center O point on the top view. S and L have the relationship shown in formula (4).

[0057]

[0058] Based on this, for each collected ball surface image (L image), the spherical image displacement calculation can be used to convert it into the corresponding S image. Subsequently, the S image is used as input to calculate the displacement between the two frames of images.

[0059] The communication module is used to support the signal processing module 16 to communicate with an external computer. Specifically, the communication module may include a wired communication module and / or a wireless communication module. The design of combining the wired communication module and the wireless communication module can make the mouse of the present invention more convenient to use. The wireless communication module may specifically include a wireless transmitter, which may specifically be a wireless transmitter with a USB interface, which is used to be inserted into a computer host and transmit signals to the computer host.

[0060] The power supply module 17 is used to supply power to the image acquisition module 15 and the signal processing module 16. The power supply module 17 may be a battery. The battery may be a rechargeable battery, in which case the power supply module 17 may further include a charging interface, and the rechargeable battery draws power from an external power source through the charging interface during the charging process.

[0061] The present invention adopts the above technical scheme, by setting a ball with a pattern on the surface at the pen tip of the main body, when the mouse moves, the ball keeps rolling, the image acquisition module continuously collects the image on the surface of the ball, and then the moving direction of the mouse can be determined by analyzing the continuously collected images, so that the mouse of the present invention does not need a mouse pad when in use, and is easy to use; and by setting a microscope eyepiece in the image acquisition module, the image acquisition module receives the light reflected by the ball through the microscope eyepiece, and the microscope eyepiece magnifies the ball under the visual angle of the image acquisition module, so that the slight rotation of the ball can also be recognized, and the accuracy of the mouse is improved; on this basis, since the mouse of the present invention can write like a pen, and the accuracy is high, the computer screen can be used as a writing board, and the mouse of the present invention can be used for writing, drawing and other operations, thereby expanding the function and use range of the mouse, for example, it can be applied to three-dimensional modeling software and art and calligraphy software, so that students and staff who use these software for classes and office work no longer need to purchase electronic drawing boards, and the accuracy is higher than the electronic drawing boards in these markets. In addition, putting calligraphy on the screen helps to inherit the excellent traditional Chinese culture.

[0062] Furthermore, the mouse of the present invention has a simple structure and a small size, and is convenient to carry or embed in a notebook computer, which further improves the convenience of using the mouse of the present invention.
