[0014] The virtual laser scanning visualization device provided by the present invention solves the technical problem that in conventional means of shooting to obtain a film and television work, the laser beam cannot be displayed because it is invisible light, while the present invention simulates laser scanning in a virtual space to make the laser beam in the film and television work visible, thus more vividly presenting the laser scanning process.

[0015] Further, it further includes a first adjustment module, and the first adjustment module is used to hierarchically adjust the line widths of all the line segments so that the simulated laser beam obtains a sense of hierarchy.

[0016] Further, when the first adjustment module is used to hierarchically adjust the line widths of all the line segments so that the simulated laser beam obtains a sense of hierarchy, it performs: S51.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0031] It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present invention, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0032] Referring to the attached Figure 1 、attached Figure 2 、attached Figure 3 and attached Figure 5 , the present invention provides a virtual laser scanning visualization method, including the following steps: S1. Export target data; the target data includes the three-dimensional data of all target models in reality, the laser source position, and the camera position; S2. Based on the view of the current camera position, according to the target data, use the preset three-dimensional particle tool of points, lines, and surfaces to process the three-dimensional data of all target models, so that all target models are presented in the form of points in the current view; S3. After being processed in step S2, connect the points of all target models in the current view to the laser source position to form line segments; the line segments are used as simulated laser beams; S4. According to the preset ratio, control some line segments and the points corresponding to the line segments on the target models to cycle between display and hiding in any time frame, so that the simulated laser beam obtains a dynamic scanning effect.

[0033] In step S1, export the target data. The target data includes the three-dimensional data of the real model, the laser source position, and the camera position, providing a data basis for subsequent virtual laser scanning.

[0034] In step S2, based on the camera view, according to the target data, use the three-dimensional particle tool to process the three-dimensional data of all target models. All target models are presented in the form of points in the current view, facilitating the simulation of the action points of the laser scan on the object surface.

[0035] In step S3, after being processed in step S2, the points of all target models in the current view are connected to the laser source position to form line segments. The line segments are used as simulated laser beams to show the laser path and the interaction with the target models.

[0036] In step S4, according to the preset ratio, some line segments and the points corresponding to the line segments on the target models cycle between display and hiding in any time frame, and the simulated laser beam obtains a dynamic scanning effect.

[0037] As a preferred implementation, in step S1, the target data can be exported from 3D modeling software, and the exported data format can be a common format such as OBJ or FBX. In step S2, the three-dimensional particle tool can be implemented using the particle system in the graphics engine. By projecting the model vertices onto the camera view and converting them into particles, the model is made point-like. In step S3, the generation of line segments can be achieved by drawing line segments in the graphics engine, with each line segment connecting the model points and the laser source position. In step S4, the dynamic display effect can be achieved by controlling the visibility of the line segments and points through a time-driven script, and the preset ratio determines the frequency and quantity of display and hiding.

[0038] Specifically, this virtual laser scanning visualization method aims to enhance the visual effect of virtual laser scanning. In step S1, target data is exported to provide the necessary position information of the 3D model, laser source, and camera for subsequent virtual laser scanning, thereby constructing the basis of the virtual scene. In step S2, based on the camera view, the target model is processed into a point form using a 3D particle tool to facilitate simulating the action points of laser scanning on the object surface. In step S3, the points on the model and the laser source position are connected into line segments to simulate the path of the laser beam and visually display the interaction between the laser and the target model. In step S4, by presetting a ratio to cyclically display and hide some line segments and corresponding points, a dynamic scanning effect of the laser beam is simulated, overcoming the dullness of static display and more vividly presenting the laser scanning process. Thus, the technical problem that the laser scanning process cannot be displayed in the film and television works obtained by conventional means because the laser beam is invisible light is solved. In this invention, the laser scanning is simulated in the virtual space, making the laser beam in the film and television works visual, and thus more vividly presenting the laser scanning process.

[0039] In some specific embodiments, the virtual laser scanning visualization method is used to demonstrate the process of laser scanning an automobile model. First, the target data such as the 3D data of the automobile model, the laser source position, and the camera position are exported from the software. Then, the target data is imported into the visualization software. Next, the automobile model is converted into a point cloud form using a 3D particle tool, and in the camera view, the automobile model is presented in the form of points. After that, each point is connected to the set laser source position to form line segments simulating the laser beam. Finally, the preset ratio is set to 50%, and through program control, 50% of the line segments and their corresponding points are cyclically displayed and hidden in each frame, thereby simulating the dynamic effect of laser scanning and vividly demonstrating the process of laser scanning the automobile model.

[0040] It should be noted that this invention uses Adobe After Effects software (hereinafter referred to as AE software) to perform related operations, including but not limited to using a 3D particle tool (the 3D particle tool is used as a plugin in AE software), and including controlling the display and hiding of line segments, as well as adjusting the line width of line segments, adding noise, constructing the model bottom layer, coloring, and glow effects as described below.

[0041] In certain embodiments, referring to the appendix Figure 4 , there is also a step between step S3 and step S4: S5. Gradually adjust the line width of all line segments to give the simulated laser beam a sense of hierarchy.

[0042] In view of the problem that the simulated laser beam may lack visual depth and realism, a line width graded adjustment method is proposed. Specifically, the line width graded adjustment refers to assigning different line width values to the line segments according to their position or depth in three-dimensional space. As a result, the simulated laser beam is no longer a flattened effect in which all line segments have the same width, but presents a three-dimensional effect with visual depth. The adjustment of the line width can be based on the distance between the line segment and the camera. The closer the line segment is to the camera, the wider the line width can be set. Conversely, the farther the line segment is from the camera, the narrower the line width can be set. In this way, the front end of the simulated laser beam looks thick and the back end gradually becomes thinner, which is more in line with the perspective law of the human eye observing objects, thereby enhancing the realism and layering of the simulated laser beam.

[0043] Specifically, by adjusting the line width of the line segments in stages, the visual effect of the simulated laser beam is effectively improved. Without the graded adjustment of the line width, all line segments of the simulated laser beam may have the same width, causing the simulated laser beam to look flat and lack depth. The introduction of step S5 allows the line segments in the simulated laser beam to be assigned different line widths according to their spatial positions, creating a visual attenuation effect from near to far. This visual effect simulates the intensity or diffusion changes that may occur when a real laser beam propagates in space, making the simulated laser beam more visually informative and closer to the effect of real laser scanning. As a result, observers can more easily perceive the scanning path and spatial relationship of the simulated laser beam, and the visualization effect is conducive to enhancing the ability and appeal of information expression.

[0044] In some specific embodiments, the line width value can be divided into multiple levels according to the distance between the line segment and the camera. For example, three line width levels are set: close distance, medium distance and long distance. For the line segment at close distance, the thickest line width is used; for the line segment at medium distance, the medium line width is used; for the line segment at long distance, the thinnest line width is used. The distance level to which the line segment belongs can be determined based on a preset distance threshold range. Through this graded line width adjustment, the layering and depth of the simulated laser beam can be effectively expressed.

[0045] In certain embodiments, referring to Figure 5 , the specific steps in step S5 include: S51. Add noise to all line segments and dynamically adjust the line width of all line segments by controlling the noise amplitude.

[0046] Adding noise to all line segments means that for each constituent line segment of the simulated laser beam, a random variation is introduced in the line width performance. This randomness is provided by the noise, making the width of the line segment no longer constant but fluctuate within a certain range. Further, by controlling the noise amplitude to dynamically adjust the line width of all line segments, fine control over the degree of line width fluctuation is achieved. Adjusting the noise amplitude parameter directly affects the amplitude of the line width change. The larger the amplitude, the wider the fluctuation range of the line width, and vice versa. Thus, the line width of the simulated laser beam exhibits a dynamic and irregular change, more closely approximating the visual effect of a real laser beam.

[0047] Specifically, to make the simulated laser beam achieve a more natural dynamic scanning effect, the adjustment of the line width is no longer a simple linear scaling, but a random signal called noise is introduced. The noise is superimposed on the base line width of the line segment to form the final line width value. Due to the randomness of the noise, the line width of each line segment will produce subtle and irregular fluctuations around the base value. This fluctuation is real-time and dynamic, and as time goes by, the line width will continue to change. By adjusting the noise amplitude, the severity of the line width fluctuation can be controlled. A smaller amplitude produces a slight line width change, simulating a subtle laser beam jitter; a larger amplitude produces a more obvious line width change, simulating the sense of energy fluctuation during the laser beam scanning process. This dynamic noise adjustment method makes the simulated laser beam more visually layered and realistic, overcoming the stiffness and unnaturalness of static line width adjustment.

[0048] In some specific embodiments, the dynamic adjustment of the line width is achieved through a programmed approach. For example, in a graphics rendering engine, a shader program can be written to introduce a noise function when calculating the pixel color for each line segment that makes up the simulated laser beam. The input of the noise function can be time, the index of the line segment, or other parameters, and the output is a random noise value. This noise value is used to modulate the line width of the line segment, so that the width of the finally rendered line segment has a random and dynamic change. The type of noise can be selected as Perlin noise, Simplex noise, Gaussian noise, etc., and the amplitude of the noise is used as an adjustable parameter, exposed to the user interface or configuration system to adjust the dynamic effect of the simulated laser beam as needed.

[0049] In certain embodiments, referring to Appendix Figure 6 , after step S4, the following steps are further included: S6. Construct the underlying model using the points of the target model, and change the color of the points corresponding to the displayed line segments in the underlying model to the color of the displayed line segments; the color of the displayed line segments is different from the color of the points in the underlying model.

[0050] The underlying layer of the model is constructed from the point data on the surface of the target model. When the simulated laser beam is displayed, the color of the points at the corresponding positions in the underlying layer of the model is modified to the color of the laser beam. The color of the laser beam is set to be different from the color of the points in the underlying layer of the model to visually distinguish the scanning trajectory.

[0051] Specifically, to address the problem of lack of visual association, a point set covering the surface of the model is constructed using the point data of the target model as the underlying layer of the model. During the simulation of the laser beam scanning process, when the simulated laser beam projects onto the surface of the model, the intersection points of the laser beam and the underlying layer of the model are determined. Then, the color of the points at the intersection positions on the underlying layer of the model is changed to the same color as the laser beam. Since there is a difference between the color of the laser beam and the original color of the points in the underlying layer of the model, the scanning trajectory of the simulated laser beam on the surface of the model is clearly visually presented through the color change. Thus, a visual association is established between the simulated laser beam and the target model, reflecting the scanning effect of the simulated laser beam on the target model and enhancing the realism of the scanning process.

[0052] In some specific embodiments, virtual laser scanning visualization simulation is performed on a car model. First, the three-dimensional point cloud data of the car model is obtained (this three-dimensional point cloud data can be used as the top layer of the model and is displayed in blue). Then, the underlying layer of the car model is constructed based on this point cloud data. When simulating laser scanning, the laser beam is displayed as a red line segment. When the red laser beam scans the surface of the car model, the points on the underlying layer that intersect with the red laser beam are synchronously modified to red. As the scanning process progresses, a red scanning trajectory will appear on the surface of the car model, and this red scanning trajectory forms a visual echo with the red laser beam, thus vividly demonstrating the scanning process of the laser beam on the car model.

[0053] In certain embodiments, refer to Appendix Figure 6 , after step S6, the following steps are further included: S7. Add special effect data to all displayed line segments and make all displayed line segments obtain a glow effect by controlling relevant parameters.

[0054] The special effect data is added to the displayed line segments through graphics rendering technology to produce a glow effect. The relevant parameters are the attributes used to adjust the glow effect, such as glow color, glow intensity, and glow range. By controlling these parameters, the visual performance of the glow effect can be finely adjusted. The glow effect is a visual enhancement technology that simulates the luminous characteristics of a real laser beam, which makes a halo appear around the line segment, thus enhancing the brightness and prominence of the simulated laser beam visually.

[0055] Specifically, in order to make the visual effect of the simulated laser beam more vivid and realistic, after the bottom layer of the model is constructed and the color is changed in step S6, step S7 is further executed. In step S7, first, special effect data for implementing the glow effect is attached to all the displayed line segments. Then, by adjusting the parameters related to the glow effect, such as setting the glow color to the color of the laser beam and adjusting the glow intensity and glow range to appropriate values, a halo around the line segment itself is presented for the displayed line segments. Thus, the simulated laser beam becomes more prominent and eye-catching visually, closer to the effect of laser scanning in reality, enhancing the vividness and visual attractiveness of the virtual laser scanning process and solving the problem that the visual effect of the simulated laser beam is not vivid enough.

[0056] In some specific embodiments, the special effect data can be implemented using a shader program, and the shader program is configured to calculate and render the glow effect. For example, the shader program can first obtain the color information of the displayed line segment, and then generate a brighter and larger-range halo than the color of the original line segment through a blur algorithm, and superimpose the halo on the original line segment to form the glow effect. Parameters such as the glow color, intensity, and range can be set as adjustable parameters in the shader program for control and adjustment as needed. By adopting this method, the glow effect can be effectively added to the displayed line segments, enhancing the visual effect of the virtual laser scanning visualization method.
