Description

Technical Field

[0002] 3D animation production is to produce animation by simulating the movement and change process of solid objects or environments in 3D space. It has the characteristics of highly realistic visual effects, high degree of freedom in creative space, strong editability and wide application fields. In the process of 3D animation production, scanning devices are used for assistance. 3D scanning devices can capture the shape and details of objects with high precision, provide basic models for 3D animation production, and obtain their 3D models and detailed features by scanning real actors, and then create digital doubles with high similarity, complete the performance of difficult or dangerous actions, and digitally restore outdoor or studio scenes in all directions, as well as prototypes of real props, to provide high-quality virtual effects and realistic props for film and television animation, thus providing convenience for later creation;

[0003] The 3D animation production method and device disclosed in the publication number CN104658022A extracts the skeleton frame information of the character main body, calibrates the skeleton key points in the skeleton frame, and corresponds the skeleton key points to the corresponding model key points in the pre-made 3D model one by one. The movement of the model key points is determined according to the movement of the skeleton key points, thereby driving the movement of the 3D model. Therefore, the 3D animation can be driven by the action of the video character, and the animation can be generated in real time, thereby improving the production efficiency of the animation:

[0004] However, the above scheme still has the following problems during use: when using a scanning device to scan and process the reference model, due to the different appearances of characters of various specifications in the creation of three-dimensional animation, the same character will have different models under different actions. Therefore, when performing a comprehensive scan, a single scanning direction and angle may easily cause incomplete scanning and incomplete model detail data. Therefore, it is necessary to perform adaptive adjustments according to the specifications and posture of the model, so as to obtain more comprehensive and accurate three-dimensional model parameter information.

[0005] Therefore, we propose an efficient 3D animation production method and scanning device to solve the above problems. Summary of the invention

[0050] Please refer to Figure 2 , Figure 7 , Fig. 9 , Fig.10 and Fig.12 As shown, first, the basic components of the scanning device are introduced. When scanning a model, the model is placed on the placement table 3 on the bottom plate 1, the placement table 3 rotates, and the scanning head 8 emits a scanning beam to the surface of the model, thereby quickly obtaining a multi-point view. After the first screw 5 in the slide rail 4 rotates, it can drive the base 6 to move, and the base 6 drives the scanning head 8 to move synchronously through the mounting plate 7, so as to perform a comprehensive scan of the model from top to bottom, and use the collected sparse point cloud model as a constraint to perform three-dimensional reconstruction based on stereo vision, and after fusion, a dense point cloud model is obtained;

[0051] Embodiment 1: In order to prevent the model from moving during the rotation process and affecting the scanning quality during the use of the scanning device, the following solution is proposed. For details, please refer to Figure 2 - Figure 6 As shown;

[0052] Positioning assembly 9, positioning assembly 9 is arranged on the storage table 3, and positioning assembly 9 positions the model placed on the storage table 3 to avoid displacement during rotation, positioning assembly 9 includes a disc 901 rotatably connected to the inside of the storage table 3, and the disc 901 is started by a motor inside the storage table 3, and an arc-shaped guide groove 902 is opened at an angle on the disc 901, and a positioning plate 903 is slidably connected in the guide groove 902, and at the same time, the positioning plate 903 is connected through the top and bottom of the storage table 3, and the top and bottom of the positioning plate 903 are slidably connected in the rectangular limiting groove 904, and the limiting groove 904 is opened at the top and bottom of the storage table 3 at equal angles, and the positioning plate 903 forms an opening and closing interactive structure through the guide groove 902 and the limiting groove 904, and the positioning plate 903 is used to position and fix the model on the storage table 3;

[0053] During positioning, after the model is placed on the storage table 3, the motor drives the disc 901 to rotate, and the disc 901 rotates to drive the guide groove 902 to rotate synchronously, and the guide groove 902 drives the positioning plate 903 to slide synchronously in the limit groove 904, so that the positioning plates 903 around it open and close and slide, so as to position and fix the model to be scanned, and avoid the model shaking when the storage table 3 rotates;

[0054] In order to prevent the positioning components from affecting the scanning, the following solution is proposed. Please refer to Figure 2 - Figure 6 As shown,

[0055] A spring 905 is symmetrically installed on the outer side of the bottom of the positioning plate 903, and the top of the spring 905 fits and slides with the bottom of the lower limiting groove 904, and a fan-shaped electromagnet 906 is installed on the top of the bottom plate 1, and an iron sheet is provided at the bottom of the positioning plate 903, and the positioning plate 903 forms a vertical sliding structure through the electromagnet 906;

[0056] During operation, when the positioning plate 903 opens and closes and slides, the spring 905 is driven to slide synchronously. After the electromagnet 906 on the bottom plate 1 is energized, each time the positioning plate 903 passes the electromagnet 906, it will be attracted and moved downward, thereby causing the positioning plate 903 to slide in a vertical direction, thereby stretching the spring 905 and retracting it into the inner part of the limiting groove 904, thereby ensuring that the scanning line will not be affected by the positioning plate 903 when scanning the model. When the positioning plate 903 misses the electromagnet 906, the positioning plate 903 will be reset under the elastic force of the spring 905, and then continue to position the model, thereby ensuring the stability of the model while not affecting the scanning work;

[0057] Embodiment 2: When scanning models of different specifications, in order to automatically adapt to the model specifications and adjust the rotation angle of the scanning head 8, the following solution is proposed. For details, please refer to Figure 2- Fig. 9 As shown,

[0058] Angle adjustment component 10, the angle adjustment component 10 is arranged inside the storage table 3 and between the mounting plate 7 and the bottom of the scanning head 8, and the angle adjustment component 10 adaptively adjusts the use angle of the scanning head 8 according to the size of the model on the storage table 3, the angle adjustment component 10 includes a second screw 101, and the second screw 101 is integrally fixed to the middle of the bottom surface of the disc 901, and a rectangular pressing plate 102 is threadedly connected to the second screw 101, and the pressing plate 102 is slidably connected to the oil chamber 103, and the oil chamber 103 is opened at the inner bottom of the storage table 3, the bottom of the oil chamber 103 is connected to the inside of the first fixed cylinder 104 through a hose, and the first fixed cylinder 104 is fixed to the bottom of the mounting plate 7, and a first piston rod 105 is slidably connected in the first fixed cylinder 104, and the right side of the first piston rod 105 is fixed to the left side of the scanning head 8, and the first fixed cylinder 104 and the first piston rod 105 are both arranged as arc structures;

[0059] During automatic adjustment, the disc 901 rotates to drive the second screw 101 at the bottom to rotate synchronously. The second screw 101 rotates to drive the pressure plate 102 to slide in the oil chamber 103, thereby squeezing out the oil in the oil chamber 103, and then transporting it to the first fixed cylinder 104 through a hose. After the first fixed cylinder 104 is injected with oil, the pressure increases, which pushes the first piston rod 105 to extend, thereby driving the scanning head 8 to rotate adaptively on the mounting plate 7, so that the scanning head 8 is in a state of facing the model;

[0060] Example 3: For models with different body shapes, in order to perform more comprehensive scanning and avoid missing details, the following solution is proposed. Please refer to Figure 2 , Figure 7 , Fig. 9 - Fig.12 As shown,

[0061] The flip assembly 11 is arranged between the mounting plate 7 and the top of the scanning head 8 and on the right side of the side plate 2, and the flip assembly 11 adjusts the overall pitch angle of the scanning head 8 according to the different postures of the model on the storage table 3. The flip assembly 11 includes a second piston rod 111 symmetrically mounted on the top of the scanning head 8, and the second piston rod 111 is slidably connected to the second fixed cylinder 112, and the second fixed cylinder 112 is symmetrically mounted on the top of the mounting plate 7;

[0062] After the scanning head 8 rotates, it will synchronously drive the second piston rod 111 to slide in the second fixed cylinder 112, and the oil in the second fixed cylinder 112 will be squeezed out. When the base 6 drives the scanning head 8 to move downward through the mounting plate 7, the scanning head 8 will contact the bevel of the guide plate 115, so that the mounting plate 7 and the scanning head 8 are gradually turned over as a whole, so as to scan the bottom details of the model;

[0063] For different body models, in order to avoid the phenomenon of incomplete scanning, the overall flipping speed of the scanning head 8 is adjusted in time, so the following solution is proposed, please refer to Figure 2 , Figure 7 and Fig. 9 - Fig.12 As shown,

[0064] The second fixed cylinder 112 is connected to the oil pipe 113 through a hose, and the oil pipe 113 is symmetrically installed on the right side of the side plate 2, and a sliding rod 114 is slidably connected in the oil pipe 113, and the sliding rod 114 is connected to the bottom left side of the guide plate 115, and the guide plate 115 is symmetrically hinged on the right side surface of the side plate 2, and the guide plate 115 is set as a right-angle trapezoidal structure as a whole, and the hypotenuse of the guide plate 115 contacts the left side of the scanning head 8, and a ball is embedded on the left side of the scanning head 8, and the guide plate 115 forms an angle adjustment structure through the oil pipe 113 and the sliding rod 114;

[0065] After the second piston rod 111 slides in the second fixed cylinder 112, the oil will be transported to the oil pipe 113 through the hose. The oil pipe 113 will push the sliding rod 114 to extend, and the sliding rod 114 will push the guide plate 115 to rotate, thereby adjusting the inclination angle of the inclined surface of the guide plate 115, so that when the scanning head 8 moves from top to bottom, the flip angle can be adaptively adjusted to more comprehensively scan the blocked parts at the bottom of the model to avoid omissions.
