[0034] Embodiment one

[0035] Figure 1 is a flowchart of a modeling method provided by the embodiment one of the present application. The embodiment can be applicable to the case that the enlarged positioning sleeve model is not closely fitted with the corresponding part simulation model, and the positioning sleeve model is fixed on the part simulation model by constructing a target fixing part. The method can be executed by a modeling device, which can be realized in the form of hardware and / or software, and can be configured in a terminal and / or a server. As shown in the figure, the method comprises: Figure 1

[0036] S110, based on the pre-acquired part simulation model, constructing a positioning sleeve model matched with the part simulation model, and performing amplification processing on the positioning sleeve model to obtain a to-be-processed sleeve model.

[0037] The part simulation model can be a three-dimensional simulation model constructed based on an arbitrary to-be-detected part of a target object. For example, when the to-be-detected part is a head, the part simulation model can be a head simulation model. In actual application, the part simulation model can be constructed based on scanning data of the corresponding part. Specifically, the to-be-detected part of the target object can be scanned based on a scanning device to obtain scanning data of the to-be-detected part, and then the scanning data can be processed by image segmentation, smoothing, three-dimensional isosurface reconstruction, etc. to obtain the part simulation model corresponding to the to-be-detected part. ​

[0038] The positioning kit model can be a model covering the outer layer of the part simulation model, or can be understood as a model closely fitted with the part simulation model. For example, if the part simulation model is a head simulation model, the positioning kit model can be a positioning head cover model.

[0039] In actual application, first, a corresponding part simulation model can be constructed based on the scanning data of the part to be detected, then, the part surrounding area can be determined based on the spatial position relationship of the part simulation model in the image space coordinate system, and the extension direction and extension distance of the part surrounding area can be determined according to the part simulation model, so as to extend the part surrounding area based on the extension mode to obtain the positioning kit model. For example, for different parts to be detected, the construction mode of the corresponding positioning kit model is different, and the present embodiment takes the head as an example to illustrate the determination process of the positioning kit model: 1, determining the brain structure model and the head structure model of the target object based on the head portrait of the target object; 2, determining the target position of the coil structure model and the target posture of the coil structure model at the target position based on the target target point in the brain structure model, the stimulation hot spot in the coil structure model of the target coil, and the head structure model of the target object; 3, determining the head surrounding area in the image space coordinate system, determining the extension direction and extension distance of the head surrounding area according to the head structure model, and extending the head surrounding area according to the extension direction and extension distance of the head surrounding area to obtain the head positioning model; 4, establishing the coil positioning model based on the target position, the target posture and the coil structure model, and determining the processing positioning model based on the head positioning model and the coil positioning model; 5, determining the positioning head cover model based on the processing positioning model, the head structure model and the coil structure model.

[0040] Further, after obtaining the positioning kit model, the positioning kit model can be enlarged according to a preset ratio, that is, the processing kit model can be obtained. The processing kit model can be a three-dimensional model with the same overall contour as the positioning kit model but different model size. The preset ratio can be any ratio, which can be 10% optionally.

[0041] S120, when it is detected that the relative position relationship between the part simulation model and the processing kit model meets the preset condition, determining the target simulation model of at least one target fixing part based on at least one marker point on the part simulation model and the processing kit model.

[0042] The preset condition can be pre-set, and is used to determine the relative position relationship between the part simulation model and the corresponding set model. In the embodiment, when the relative position relationship between the part simulation model and the set model to be processed is that the part simulation model is in the set model to be processed, it is determined that the preset condition is met. Alternatively, when the set model to be processed is overlaid on the part simulation model, it is determined that the preset condition is met. In actual application, a model position moving control can be pre-developed. When a triggering operation of the control is detected, the relative position relationship between the set model to be processed and the part simulation model is detected, and when the relative position relationship between the two models meets the preset condition, the moving operation of the model is stopped. Alternatively, the set model to be processed or the part simulation model can be set to an editable state. The set model to be processed or the part simulation model can be moved based on an input device or a user's finger. When the relative position relationship between the set model to be processed and the part simulation model meets the preset condition during the moving process, the moving operation is stopped. For example, when the part simulation model is a head simulation model and the set model to be processed is an enlarged positioning head set model, when the enlarged positioning head set model is sleeved on the head simulation model, that is, when the region above the glabella in the head simulation model is located in the inner groove of the enlarged positioning head set model, it is determined that the preset condition is met.

[0043] The marking point can be a fixed guide point pre-determined on the part simulation model. In the embodiment, the marking point can be an anatomical marking point on the part to be detected. For example, when the part simulation model is a head simulation model, the marking points can be points corresponding to the left corner of the eye, the right corner of the eye and the tip of the nose.

[0044] The target fixed part can be a fixed part used to fix the set model to be processed on the part simulation model. Correspondingly, the target simulation model can be a three-dimensional simulation model constructed based on the target fixed part. In actual application, the positioning set model is constructed based on the part simulation model, and is a model that is mutually fitted with the part simulation model. The set model to be processed is obtained by enlarging the positioning set model. When the relative position relationship between the set model to be processed and the part simulation model meets the preset condition, the set model to be processed can not be fixed on the part simulation model without the support of the fixed part. Therefore, the target fixed part used to fix the set model to be processed on the part simulation model can be constructed.

[0045] It should be noted that the target fixed part can be a single integral component or a combined component including at least two components. When the target fixed part is in different forms, the corresponding determination methods can be different.

[0046] Optionally, if the target fixing member is a single integral component, the corresponding determination process can be: determining the mark point on the part simulation model and the fixing point on the to-be-processed set model; determining the spatial position relationship between the mark point and the fixing point; further, determining the height of the target fixing member and the length between the target fixing member and the to-be-processed set model according to the spatial position relationship, so as to construct the target simulation model of the target fixing member based on the height and the length.

[0047] Optionally, if the target fixing member is a combined component including at least two components, the corresponding determination process can be: determining the mark point on the part simulation model and the fixing point on the to-be-processed set model, determining the height of the first simulation model according to the spatial position relationship between the mark point and the fixing point, so as to construct the first simulation model of the first fixing member based on the height; further, determining the target length of the second simulation model according to the spatial position relationship between the model end point adjacent to the fixing point on the first simulation model and the fixing point, then constructing the second simulation model of the second fixing member according to the target length and the preset included angle between the first simulation model and the second simulation model, and finally combining the first simulation model and the second simulation model together to obtain the target simulation model of the target fixing member.

[0048] In actual application, after obtaining the to-be-processed set model, the relative position relationship between the to-be-processed set model and the part simulation model can be detected, and when it is detected that the relative position relationship between the to-be-processed set model and the part simulation model satisfies the preset condition, the mark point position information of the at least one mark point pre-determined on the part simulation model can be determined, and then the target simulation model of the at least one target fixing member can be determined according to the mark point position information of the mark points and the to-be-processed set model.

[0049] It should be noted that after obtaining the target simulation model of the at least one target fixing member, in order to combine the target fixing member and the to-be-processed set together when the to-be-processed set corresponding to the target fixing member and the to-be-processed set model is applied, and to store the target fixing member and the to-be-processed set separately when the target fixing member and the to-be-processed set are not applied, so as to save the storage space, a fixing hole matched with the target simulation model can be formed on the to-be-processed set model, so that the target simulation model and the to-be-processed set model can be matched with each other based on the corresponding fixing hole.

[0050] Based on the above technical solutions, the method further includes: determining the installation hole corresponding to the at least one target simulation model on the to-be-processed set model; and taking the at least one target simulation model and the to-be-processed set model as a target set model.

[0051] In the embodiment, the mounting hole can be a groove formed on the to-be-processed kit model, and a shape of the groove matches a structure of the model close to the to-be-processed kit model in the target simulation model. For example, if the structure of the model close to the to-be-processed kit model in the target simulation model is a cuboid, the shape of the mounting hole is a cuboid groove.

[0052] In actual application, after obtaining the target simulation model and the to-be-processed kit model, Boolean operation can be performed on the target simulation model and the to-be-processed kit model to complete the operation of determining the difference between the two models, and the corresponding mounting hole is obtained, that is, after the to-be-processed kit model and the target simulation model are combined together, the part of the to-be-processed kit model coinciding with the target simulation model is removed, and further, after the mounting hole corresponding to each target simulation model is determined on the to-be-processed kit model, at least one target simulation model and the to-be-processed kit model can be combined together to be used as a target kit model.

[0053] In actual application, after obtaining the to-be-processed kit model and the target simulation model of the corresponding target fixing part, the to-be-processed kit and the target fixing part can be prepared based on a model preparation mode, so as to fix the to-be-processed kit on the to-be-detected part of the target object based on the prepared target fixing part. Optionally, the model preparation mode can include but is not limited to 3D printing, injection molding, or other model preparation modes to materialize the target simulation model and the to-be-processed kit model.

[0054] The technical scheme of the embodiment of the application, by constructing a positioning kit model matched with the part simulation model based on the pre-acquired part simulation model, and performing amplification processing on the positioning kit model to obtain a to-be-processed kit model, when the relative position relationship between the part simulation model and the to-be-processed kit model meets a preset condition, determining a target simulation model of at least one target fixing part based on at least one mark point pre-determined on the part simulation model and the to-be-processed kit model, solves the problems in the prior art that if no tolerance is set, the head of the target object and the helmet are tightly attached together, which causes the head of the target object to bear huge pressure, or if a tolerance is set, the positioning accuracy of the positioning helmet is reduced, and achieves the effect of improving the positioning accuracy of the positioning helmet under the premise that there is a tolerance between the positioning helmet and the head of the target object, and achieves the effect of assisting the positioning helmet to accurately position the target stimulation point.

[0055] Embodiment two

[0056] Figure 2is a flowchart of a modeling method provided in Embodiment Two of the present application. On the basis of the foregoing embodiment, the target fixing part can include a first fixing part and a second fixing part. When the target fixing part is constructed, a first simulation model of the first fixing part can be constructed first, and then a second simulation model of the second fixing part is constructed based on the first simulation model. Thus, the target simulation model of the target fixing part can be determined based on the first simulation model and the second simulation model. Wherein, the same or corresponding technical terms as in the foregoing embodiment are not repeated here.

[0057] As shown in Figure 2 , the method comprises:

[0058] S210, based on the pre-acquired part simulation model, a positioning kit model matched with the part simulation model is constructed, and the positioning kit model is enlarged to obtain a to-be-processed kit model.

[0059] S220, when it is detected that the relative position relationship between the part simulation model and the to-be-processed kit model meets a preset condition, a first simulation model of at least one first fixing part is constructed based on at least one marker point pre-determined on the part simulation model and the to-be-processed kit model.

[0060] In the present embodiment, the first fixing part can be one of the components used to compose the target fixing part. Correspondingly, the first simulation model can be a three-dimensional simulation model constructed based on the first fixing part.

[0061] In actual application, the marker point position information of the marker point on the part simulation model can be determined first, and then the fixed point position information of the fixed point on the to-be-processed kit model corresponding to the marker point can be determined. Further, the height value of the first simulation model can be determined according to the marker point position information and the fixed point position information, so as to construct the first simulation model of the first fixing part based on the height value.

[0062] Optionally, based on the at least one marker point pre-determined on the part simulation model and the to-be-processed kit model, the first simulation model of the at least one first fixing part is constructed, comprising: determining a fixed point on the to-be-processed kit model corresponding to the marker point; determining the first spatial position information between the marker point and the fixed point, and constructing the first simulation model of the first fixing part based on the first spatial position information.

[0063] In the embodiment, the fixed point can be a point on the to-be-processed kit model for fixing the target fixed part. The first spatial position relationship can be a position relationship of the mark point and the fixed point corresponding thereto in an image space coordinate system. In actual application, after the mark point and the fixed point corresponding thereto are determined, the spatial coordinates of the mark point in the image space coordinate system and the spatial coordinates of the fixed point in the same image space coordinate system can be obtained. Further, the first spatial position information between the mark point and the fixed point can be determined according to the two spatial coordinates, and then the height value of the first simulation model can be determined based on the first spatial position information, so that the first simulation model of the first fixed part can be constructed according to the height value.

[0064] It should be noted that the model diameter of the first simulation model can be any value, which is not limited in the embodiment.

[0065] For example, the first fixed part can be a cylinder with a diameter of 5 mm, the center of the lower surface of the cylinder is located at the position of the mark point, the upper surface of the cylinder can be located at the fixed point on the to-be-processed kit model, and the cylinder does not intersect with the to-be-processed kit model.

[0066] It should be noted that the number of the first fixed parts matches the number of the mark points on the pre-determined position simulation model. For example, if the number of the mark points is 3, the number of the constructed first fixed parts is also 3.

[0067] S230, based on the first simulation model of the first fixed part and the to-be-processed kit model, a second simulation model of a second fixed part matched with the first fixed part is constructed.

[0068] It should be noted that when the number of the first fixed parts is multiple, the number of the corresponding second fixed parts is consistent with the number of the first fixed parts, and the determination method of any second fixed part is the same, so one of the second fixed parts is taken as an example for description.

[0069] In the embodiment, the second fixed part can be one of the components for composing the target fixed part. Correspondingly, the second simulation model can be a three-dimensional simulation model constructed based on the second fixed part.

[0070] In actual application, one end of the first simulation model is adjacent to the mark point on the simulation model, and the other end is adjacent to the fixed point on the to-be-processed kit model. When the second simulation model is constructed based on the first simulation model and the to-be-processed kit model, the spatial position information of the model end point of the first simulation model adjacent to the to-be-processed kit model and the spatial position information of the corresponding fixed point on the to-be-processed kit model can be determined. Further, the model length of the second simulation model can be determined according to the two sets of spatial position information, so as to construct the second simulation model based on the model length.

[0071] Optionally, the second simulation model of the second fixing part matched with the first fixing part is constructed based on the first simulation model of the first fixing part and the to-be-processed kit model, including: determining the target length value of the second simulation model based on the second spatial position information between the model end point adjacent to the fixed point on the first simulation model and the fixed point; constructing the second simulation model of the second fixing part based on the target length and the preset included angle between the first simulation model and the second simulation model.

[0072] In the embodiment, the first simulation model is generated from the mark point along the direction of the to-be-processed kit model, so one end of the first simulation model can be adjacent to the mark point, and the other end can be adjacent to the fixed point on the to-be-processed kit model. At this time, the spatial coordinates of the model end point in the image space coordinate system can be determined, and the spatial coordinates of the fixed point determined in the image space coordinate system are obtained. Then, the spatial position information between the model end point and the fixed point is determined according to the two sets of spatial coordinates, and the spatial position information can be taken as the second spatial position information. The target length value can be the distance value between the top of the second simulation model and the bottom of the second simulation model. The preset included angle can be a preset angle used to limit the included angle when the first simulation model and the second simulation model intersect. The preset included angle can be any value, and optionally, can be 90 degrees.

[0073] In actual application, after the first simulation model is obtained, the spatial coordinates of the model end point adjacent to the fixed point in the first simulation model can be determined, and the second spatial position information between the model end point and the fixed point is determined according to the spatial coordinates and the spatial coordinates of the fixed point. Further, the target length of the second simulation model can be determined according to the second spatial position information, and then the second simulation model of the second fixing part can be constructed based on the target length and the preset included angle determined in advance.

[0074] It should be noted that the second spatial position information can be determined by determining the difference between the two sets of spatial coordinates, and when the target length of the second simulation model is determined based on the second spatial position information, the target length can be equal to or greater than the value corresponding to the second spatial position information.

[0075] For example, the first fixing member is a cylinder, and the second fixing member can be a cuboid. After the cylinder is constructed, the cuboid can be generated on the upper surface of the cylinder. The longest side of the cuboid is perpendicular to the direction of the height of the cylinder, that is, the angle between the cuboid and the cylinder is 90 degrees. The cuboid intersects with the to-be-processed kit model and penetrates into the to-be-processed kit model by more than 10 mm. At the same time, the cuboid cannot penetrate the inner wall of the to-be-processed kit model.

[0076] S240, determining a target simulation model of the target fixing member based on the first simulation model and the second simulation model.

[0077] It should be noted that the number of target fixing members is the same as the number of first fixing members and second fixing members, and is consistent with the number of predetermined mark points on the part simulation model. In addition, for each target fixing member, the corresponding determination method is the same. Therefore, one of the target fixing members is taken as an example for description.

[0078] In this embodiment, after the first simulation model and the second simulation model are obtained, the first simulation model and the second simulation model can be combined to obtain the target simulation model of the target fixing member.

[0079] Optionally, the target simulation model of the target fixing member is determined based on the first simulation model and the second simulation model, including: determining a target pose between the first simulation model and the corresponding second simulation model based on a Boolean operation principle, combining the first simulation model with the second simulation model in the target pose, and taking the combined model as the target simulation model of the corresponding target fixing member.

[0080] Those skilled in the art should understand that the Boolean operation principle is a logical deduction method of numerical symbolization, including union, intersection and subtraction. In the operation of the graphic processing, this logical operation method is used to make simple basic graphics combination to produce new shapes, and the two-dimensional Boolean operation is developed to three-dimensional graphic Boolean operation. For three-dimensional graphic Boolean operation, the union, difference and intersection operations are performed on two or more three-dimensional models to obtain a new three-dimensional model shape.

[0081] The target pose can be the model pose obtained after the union operation of the first simulation model and the second simulation model after being combined together.

[0082] In actual application, after obtaining the first simulation model and the second simulation model, the model data of the first simulation model and the model data of the second simulation model can be subjected to set operation based on the principle of Boolean operation, and then the target attitude of the first simulation model and the second simulation model combined together can be determined based on the model data after operation. Further, the first simulation model and the second simulation model can be combined together, and the first simulation model can be adjusted according to the target attitude, so that the adjusted first simulation model and the second simulation model are combined with each other, thereby the combined model is determined as the target simulation model of the target fixing part.

[0083] It should be noted that, in order to make the target simulation model and the part simulation model more fit, so as to be more stable when the to-be-processed sleeve is fixed on the to-be-detected part by the target fixing part, the target simulation model can be processed, so that the processed target simulation model can be more fit to the part simulation model.

[0084] Based on the above technical solutions, the target combination attitude between the target simulation model and the part simulation model is determined based on the principle of Boolean operation, and the target simulation model is updated based on the target combination attitude.

[0085] In this embodiment, the target combination attitude can be the attitude corresponding to the combination of the target simulation model and the part simulation model.

[0086] In actual application, the target simulation model and the part simulation model can be subjected to Boolean operation, so that the model surface of the target simulation model close to the part simulation model matches the model surface of the part simulation model contacted thereby. The combination attitude of the target simulation model and the part simulation model at this time can be taken as the target combination attitude, and further, the target simulation model can be updated based on the target combination attitude, so that the redundant part of the target simulation model close to the part simulation model is removed after matching the part simulation model, thereby the updated target simulation model can be taken as the final simulation model of the target fixing part.

[0087] The technical scheme of the embodiment of the present application, by means of the pre-acquired part simulation model, constructs a positioning suit model matched with the part simulation model, and performs amplification processing on the positioning suit model to obtain a to-be-processed suit model; when the relative position relationship between the part simulation model and the to-be-processed suit model meets a preset condition, based on at least one mark point pre-determined on the part simulation model and the to-be-processed suit model, a target simulation model of at least one target fixing part is determined, which solves the problems in the prior art that if no tolerance is set, the head of the target object and the helmet are tightly attached together, which will cause the head of the target object to bear huge pressure, or if a tolerance is set, the positioning precision of the positioning helmet is reduced, and the effect of improving the positioning precision of the positioning helmet under the premise that there is a tolerance between the positioning helmet and the head of the target object is achieved, and the effect of assisting the positioning helmet to accurately position the target stimulation point is achieved.
