Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0028] Figure 2 This is a schematic diagram illustrating the principle of fine error function calibration technology;

[0029] Figure 3 This is a schematic diagram illustrating the principle of spherical displacement calculation. Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] In modeling software such as drawing and handwriting input software, mouse input is often required. However, current mice have relatively low precision, making it difficult to meet the high accuracy requirements of modeling software. Furthermore, current mice often require a mouse pad, which is bulky and significantly reduces ease of use.

[0032] Therefore, in order to improve the accuracy and ease of use of the mouse, as well as to expand its functions and application range, this utility model provides a pen-type electronic mouse. The technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] Figure 1 This is a schematic diagram of the structure of a pen-type electronic mouse provided by an embodiment of this utility model. Figure A shows the overall structure of the pen-type electronic mouse, and Figure B shows the internal structure of the pen-type electronic mouse. Figure 1 As shown, this mouse includes: a main body 11, a button module 12, a scroll ball 13, a scroll wheel 14, an image acquisition module 15, a signal processing module 16, a power supply module 17, and a communication module. Figure 1 (Not shown in the image).

[0034] The main body 11 is pen-shaped and hollow inside. Specifically, the pen barrel of the main body 11 can be a cylindrical pen holder structure or a pen holder structure of other shapes, such as a hexagonal pyramidal pen holder structure.

[0035] The ball bearing 13 has a patterned surface and is located at the tip of the main body 11. Specifically, the surface of the ball bearing 13 may have a grooved pattern. Compared to a flat pattern, a three-dimensional grooved pattern is more wear-resistant, which helps to increase the lifespan of the mouse.

[0036] The button module 12 and scroll wheel 14 are disposed on the side wall of the pen barrel of the main body 11, with the top exposed, so that the user can click the button module 12 and scroll the scroll wheel 14. The button module 12 includes a first button and a second button. The first button is the left button of the mouse for left-clicking, and the second button is the right button of the mouse for right-clicking.

[0037] The first and second buttons can be located at the end of the main body 11 near the pen tip, and the first button can be located opposite the second button. This conforms to the user's pen-holding habits and makes it convenient for the user to click the first and second buttons.

[0038] The scroll wheel 14 can be located near the top of the main body 11, directly above the first button. This allows the user's thumb to easily switch between the first button and the scroll wheel 14 when holding the mouse, making it convenient to use. When the user scrolls the scroll wheel 14, it performs the corresponding functions of an existing mouse wheel, such as scrolling the current page.

[0039] The image acquisition module 15, signal processing module 16, and power supply module 17 are housed within the hollow structure of the main body 11. This prevents damage to the image acquisition module 15, signal processing module 16, and power supply module 17 from external factors, thus extending the lifespan of the mouse.

[0040] The image acquisition module 15 is equipped with a microscope eyepiece 151 and a photoelectric sensor 152. The image acquisition module 15 receives the light reflected from the ball bearing 13 through the microscope eyepiece 151 and generates an image of the ball bearing surface through the photoelectric sensor 152, which is then sent to the signal processing module 16. The microscope eyepiece 151 has a magnifying function, which can magnify the ball bearing under the view of the photoelectric sensor 15, so that even the slightest rotation of the ball bearing can be detected, thereby improving the accuracy of the mouse.

[0041] The signal processing module 16 is used to process the ball surface image based on a preset oversampling algorithm, fine error function calibration technology, and spherical image displacement calculation to obtain the processed ball surface image. The preset oversampling algorithm and fine error function calibration technology can improve the imaging quality, and the spherical image displacement calculation is helpful for more accurately judging the rolling of the ball in the two-dimensional direction.

[0042] Subsequently, the signal processing module 16 uses the processed ball surface image as input to calculate the displacement between corresponding two frames. The displacement calculation strategy could be to capture 1500 frames per second, with each frame having a resolution of 100×100, and use a graph cross-correlation algorithm to calculate the jump displacement between each frame, then input this result to the computer.

[0043] It should be noted that the preset oversampling algorithm, the fine error function calibration technique, and the spherical diagram displacement calculation are all existing algorithms.

[0044] The pre-defined oversampling algorithm can be the one mentioned in the article "Xue H, Shang M, Zhang Z, et al. Hyper-Sampling Imaging by Measurement of Intra-Pixel Quantum Efficiency Using Steady WaveField[J]. Laser&Photonics Reviews,2024:2401306." This algorithm, relying on steady-state low-frequency laser interference fringes, first accurately solves for the quantum efficiency distribution within the sensor pixels. This step lays a solid foundation for subsequent image processing. Based on this, 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 obtained. Compared with traditional image algorithms and deep learning methods, this algorithm has significant advantages. It not only stably improves image quality and resolution, but more importantly, it does not introduce false information. On the contrary, it can add high-frequency physical information, which is not just about improving the visual effect, but also enhances the real information contained in the image at the physical level, providing a more reliable and accurate data foundation for subsequent image-based analysis and applications.

[0045] The principle of fine error function calibration technology is explained below.

[0046] Figure 2 This is a schematic diagram illustrating the principle of fine error function calibration technology. For example... Figure 2 As shown, the grayscale value I of pixel (m,n) located in the m-th row and n-th column on the image sensor is... m,n Image sensor readout circuit gain G, exposure accumulation illumination S m,n And the number of photogenerated electrons N of the pixel m,n The relationship is:

[0047]

[0048] Among them, am,n and b m,n and c m,n These represent the dark current coefficient, linear coefficient, and nonlinear coefficient of electrons generated by pixel (m,n) under illumination, respectively. (i,j) represent the horizontal and vertical coordinates within the pixel, where 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 subpixel-level response tensor of pixel(m,n).

[0049] Before using the image sensor, the subpixel-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 an overdetermined set of equations (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 This represents the grayscale value of pixel (m, n) in the z-th frame of the image. m and n are two-dimensional coordinates in pixels on the sensor or image:

[0050]

[0051] The sensor's response tensor [a,b,c], accurate to the subpixel level, is obtained using formula (2). When using the sensor, [a,b,c] is used inversely to solve for the high-quality super-resolution image [S] of the captured target:

[0052]

[0053] 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.

[0054] The principle of spherical diagram displacement calculation is explained below.

[0055] Figure 3 This is a schematic diagram illustrating the principle of displacement calculation using a spherical diagram. For example... Figure 3 As shown, the top view of the ball (i.e., L-image) is taken through a microscope eyepiece. R is the radius of the ball, point O represents the image center, which is also the center of the ball, L represents the distance from any point on the ball surface projected onto point O in the L-image, and S represents the actual rolling path on the sphere represented by the point on the top view that is a distance L from the image center point O. S and L have the relationship shown in equation (4).

[0056]

[0057] Based on this, for each acquired ball bearing surface image (L-image), the spherical map displacement can be calculated to convert it into a corresponding S-image. Subsequently, using the S-image as input, the displacement between two image frames is calculated.

[0058] The communication module supports communication between the signal processing module 16 and an external computer. Specifically, the communication module may include a wired communication module and / or a wireless communication module. The combined design of the wired and wireless communication modules makes the mouse of this invention more convenient to use. The wireless communication module may specifically include a wireless transmitter, which may be a USB interface wireless transmitter used to plug into the computer host and transmit signals to the computer host.

[0059] The power supply module 17 supplies power to the image acquisition module 15 and the signal processing module 16. The power supply module 17 can be a battery. The battery can be a rechargeable battery, and in this case, the power supply module 17 may also include a charging interface, through which the rechargeable battery draws power from an external power source during charging.

[0060] This invention employs the above technical solutions. By setting a patterned ball bearing at the tip of the main body, the ball continuously rolls as the mouse moves, and the image acquisition module continuously captures images of the ball's surface. The direction of mouse movement can be determined by analyzing these continuously acquired images, eliminating the need for a mouse pad and making the mouse convenient to use. Furthermore, by incorporating a microscope eyepiece in the image acquisition module, the module receives light reflected from the ball, magnifying the ball's view and allowing even minute rotations to be detected, thus improving mouse precision.

For example, it can be used in 3D modeling software and art / calligraphy software, eliminating the need for students and staff using these software programs to purchase electronic drawing tablets, while offering higher precision than commercially available tablets. Moreover, bringing calligraphy to the screen helps to preserve and promote excellent traditional Chinese culture.
