FIG. 1 is a schematic diagram of one application scenario of a method for generating insole information, in accordance with some embodiments of the present disclosure.

As shown in fig. 1, an electronic device 101 for generating insole information may obtain a three-dimensional model 102 to be processed of a target foot and mechanical information 103. The three-dimensional model to be processed 102 may be used to characterize the surface structure of the target foot, and may be obtained by scanning the target foot with a 3D scanning device. The mechanical information 103 may be used to represent the stress condition of the target foot, and may be represented by a stress gradient map of the foot. The electronic device 101 may construct a target foot model 104 of the target foot based on the three-dimensional model to be processed 102 and the mechanical information 103, i.e. the target foot model 104 may characterize an ideal structure of the target foot. Finally, the electronic device 101 may generate the insole information 105 of the target foot according to the target foot model 104, so that the insole information 105 may be well suitable for the target foot, and may also guide the target foot to implement transition from the to-be-processed three-dimensional model 102 to the target foot model 104, which is beneficial to balance stress and foot shape adjustment of the target foot.

With continued reference to fig. 2, fig. 2 illustrates a flow 200 of some embodiments of a method for generating insole information in accordance with the present disclosure. The method for generating insole information comprises the following steps:

step 201, acquiring a to-be-processed three-dimensional model and mechanical information of a target foot.

In some embodiments, an executive body of the method for generating insole information (e.g., the electronic device 101 for generating insole information shown in fig. 1) may obtain the to-be-processed three-dimensional model and the mechanical information of the target foot through a wired connection or a wireless connection. Wherein the three-dimensional model to be processed may be used to characterize the surface structure of the target foot. The mechanical information is used for representing the stress condition of the target foot. For example, the three-dimensional model to be processed may be obtained by scanning the target foot with a 3D scanning device. The mechanical information can be used for displaying the stress condition of the stress surface (namely the sole) of the foot. The mechanical information may be a pressure map that detects the force applied to the foot, as shown in FIG. 1. In FIG. 1, the mechanical information 103 is a force diagram of various positions of the foot, and the left side mark pressure unit is N/cm ² (cattle per square centimeter).

Step 202, constructing a target foot model corresponding to the target foot based on the three-dimensional model to be processed and the mechanical information.

In some embodiments, after the executive body obtains the three-dimensional model to be processed and the mechanical information, a target foot model can be constructed. For example, the execution main body may directly set a marking point corresponding to the mechanical information on the three-dimensional model to be processed, so as to obtain a target foot model of the target foot. The marking points can mark corresponding stress information.

And 203, generating insole information corresponding to the target foot through the target foot model.

In some embodiments, after obtaining the target foot model, the executive may generate insole information. The insole information may include information on the shape of the insole, the structure and thickness of each location of the insole, and the like.

Some embodiments of the present disclosure disclose methods for generating insole information that result in insole information that improves the force balance of a target foot. Specifically, the reason for the unbalanced stress of the target foot is that: the target foot has poor adaptability to the shoe. Based on this, the method for generating insole information of some embodiments of the present disclosure first obtains a to-be-processed three-dimensional model and mechanical information of a target foot, and then constructs a target foot model corresponding to the target foot based on the to-be-processed three-dimensional model and the mechanical information; and finally, generating insole information corresponding to the target foot through the target foot model. Therefore, the insole information can be well suitable for the target foot, meanwhile, the target foot can be guided to realize the transition from the to-be-processed three-dimensional model to the target foot model, and the balance stress and foot shape adjustment of the target foot are facilitated.

With continued reference to fig. 3, fig. 3 illustrates a flow 300 of some embodiments of a method for generating insole information in accordance with the present disclosure. The method for generating insole information comprises the following steps:

step 301, acquiring a to-be-processed three-dimensional model and mechanical information of a target foot.

The content of step 301 is the same as that of step 201, and is not described in detail here.

Step 302, determining at least one difference parameter between the three-dimensional model to be processed and a preset reference foot model.

In some embodiments, the performing agent may pre-train the benchmark foot model. The reference foot model can be a model obtained by training a large amount of foot data, and can be used for representing information such as the bone structure of a standard foot, the stress condition of a plurality of points on the sole and the like. The executive body can compare the three-dimensional model to be processed with the benchmark foot model and obtain at least one difference parameter. Correspondingly, the difference parameter is used for representing the overall change from the reference foot model to the unit model to be processed, and can be the length, the width, the height and the like of the foot. For example, the reference foot parameter may be a length of the foot 30 cm, and a length of the foot corresponding to the three-dimensional model to be processed is 20 cm, then the difference parameter may be: the length is 10 cm less.

In some optional implementations of some embodiments, the determining at least one difference parameter between the three-dimensional model to be processed and the preset reference foot model may include: and acquiring at least one difference parameter based on the three-dimensional model to be processed and the foot reference three-dimensional model.

The reference foot model may comprise a three-dimensional foot reference model, which may be a model of the surface structure of the reference foot. The three-dimensional model to be processed represents the surface structure of the target foot, and the executive body can therefore compare the three-dimensional model to be processed with the reference three-dimensional model of the foot to obtain at least one difference parameter. The difference parameter may be the length, width, height, etc. described above.

In some optional implementations of some embodiments, the reference foot model is obtained by:

the method comprises the steps of firstly, obtaining at least one sample foot three-dimensional model and sample foot skeleton information corresponding to each sample foot three-dimensional model in the at least one sample foot three-dimensional model.

The executing subject may first obtain a plurality of sample foot three-dimensional models and corresponding sample foot skeletal information. The three-dimensional model of the sample foot is used for representing the surface structure of the sample foot and can be acquired through a 3D scanning device. The sample foot bone information is used for representing the bone characteristics of the corresponding sample foot and can be acquired through X-ray equipment and the like. The more the number of the obtained three-dimensional model of the sample foot and the corresponding skeleton information of the sample foot is, the higher the effectiveness of the reference foot model obtained by subsequent training is. It should be noted that the three-dimensional model of the sample foot and the corresponding bone information of the sample foot are obtained from a healthy and normal foot, and the foot with abnormal structure is not considered in the present application.

And secondly, matching the sample foot three-dimensional model with the sample foot skeleton information in the at least one sample foot three-dimensional model to obtain a sample initial foot model corresponding to the sample foot three-dimensional model.

The execution main body can match the sample foot three-dimensional model with corresponding sample foot skeleton information, so that a sample foot skeleton structure simulated by the sample foot skeleton information is arranged in the sample foot three-dimensional model, and a plurality of sample initial foot models are obtained.

And thirdly, fitting the at least one sample initial foot model to obtain a reference foot model.

After obtaining at least one sample initial foot model, the performing agent may place multiple sample initial foot models in the same three-dimensional space. For example, the centers of the plurality of sample initial foot models are set at the origin of the three-dimensional space, and the length directions of the plurality of sample initial foot models coincide with the X-axis of the three-dimensional space; the width directions of the plurality of sample initial foot models are coincided with the Z axis of the three-dimensional space; the height direction of the plurality of sample initial foot models coincides with the Y-axis of the three-dimensional space. Corresponding locations on the different sample initial foot models (which may be, for example, the same phalanges locations on the different sample initial foot models) are then fitted. In the fitting process, conditions such as foot length, foot width and the like are considered at the same time, and finally the reference foot model can be obtained through fitting. The resulting reference foot model may then characterize a generally healthy foot.

Step 303, determining at least one bone difference parameter corresponding to the three-dimensional model to be processed according to the at least one difference parameter.

In some embodiments, the three-dimensional model to be processed resulting from the execution of the subject is surface information of the target foot, as shown in FIG. 1. The target foot contains, in addition to surface information, the bones of the foot. To this end, the execution subject may determine at least one bone difference parameter corresponding to the three-dimensional model to be processed, based on the at least one difference parameter. For example, the executing body may stretch the reference foot model based on the difference parameter, and set the skeleton information of the stretched reference foot model as the skeleton parameter of the three-dimensional model to be processed after adjusting the reference foot model to a structure similar to the three-dimensional model to be processed. The execution body may compare the bone parameters of the reference foot model with the bone parameters of the three-dimensional model to be processed, and determine at least one bone difference parameter of the three-dimensional model to be processed.

The execution main body can also determine the bone difference parameter of the three-dimensional model to be processed according to the difference parameter in a proportional calculation mode. For example, the difference parameter is: the length is 10 cm less. The executive body may first obtain a first proportional relationship of foot length and bone length (which may be, for example, the longest of the foot bones) of the reference foot model: 10 to 8, and then calculating a second proportional relationship between the difference parameter and the foot length of the reference foot model: 3 to 1, the bone difference parameter of the three-dimensional model to be processed may be

In centimeters. Specifically, the foot length of the reference foot model is 30 cm, and the skeleton of the reference foot model is

In centimeters. The foot length of the three-dimensional model to be processed is 20 cm, and the skeleton of the three-dimensional model to be processed is

Cm, i.e. the bones corresponding to the three-dimensional model to be processed are 8 cm shorter than the bones corresponding to the reference foot model.

In some optional implementations of some embodiments, the determining at least one bone difference parameter corresponding to the three-dimensional model to be processed according to the at least one difference parameter may include:

and step one, determining the deformation amount of the three-dimensional model corresponding to the foot reference according to the at least one difference parameter.

The three-dimensional model of the foot reference may be a model of the surface structure of the reference foot, that is, the three-dimensional model of the foot reference corresponds to the external form of the reference foot. The difference parameter may be a parameter characterizing an amount of overall data change when the three-dimensional model of the foot reference is adjusted to the three-dimensional model to be processed. The executing body can determine the deformation quantity of the three-dimensional model to be processed relative to the foot reference three-dimensional model according to the at least one difference parameter. That is, the deformation amount may be a foot form change caused by the difference parameter, and may represent a local structure change amount when the foot reference three-dimensional model is adjusted to the to-be-processed three-dimensional model. For example, the difference parameter may be: the length is 10 cm less and the height is increased by 5 cm, the corresponding deformation amount can be 1 cm of arch elevation and the like.

And secondly, adjusting the at least one reference bone parameter through the deformation quantity to obtain at least one bone difference parameter.

The reference foot model may include at least one reference bone parameter corresponding to the reference three-dimensional model of the foot. The reference bone parameters may include information such as bone length, bone width, etc. of the reference foot. The execution main body can adjust the at least one reference bone parameter through the deformation quantity to obtain at least one bone difference parameter. For example, the deformation amount may be 1 cm arch elevation, and the corresponding bone difference parameter may be: the wedge bone is raised by 0.1 cm, etc.

And 304, constructing a target foot model of the target foot based on the three-dimensional model to be processed, the at least one bone difference parameter and the mechanical information.

In some embodiments, after obtaining at least one skeletal difference parameter of the target foot, the executive body may construct a target foot model of the target foot in combination with the three-dimensional model to be processed and the mechanical information. The three-dimensional model to be processed represents the surface structure of the target foot, the at least one bone difference parameter represents the bone parameter variation of the target foot relative to the reference foot, and the mechanical information represents the stress condition of the target foot. The execution main body can firstly construct a three-dimensional structure of the target foot through the three-dimensional model to be processed and at least one bone difference parameter, then a marking point corresponding to the foot stress point is set at the position of the foot corresponding to the mechanical information, the marking point can be set with a label, and the label can be used for marking the stress magnitude of the marking point.

In some optional implementations of some embodiments, the constructing a target foot model of the target foot based on the three-dimensional model to be processed, the at least one skeletal difference parameter, and the mechanical information may include:

in the first step, an initial foot model is constructed through the three-dimensional model to be processed and at least one bone difference parameter.

The three-dimensional model to be processed represents the surface structure of the target foot, and the executive body can obtain the bone parameters of the target foot through at least one bone difference parameter. The executive agent may construct an initial foot model of the target foot from the three-dimensional model to be processed and the at least one skeletal difference parameter, the initial foot model including surface structure and skeletal features of the target foot. The skeletal features included in the initial foot model are obtained directly from the reference foot model, and are estimated models of the skeleton of the target foot.

And secondly, adjusting the initial foot model based on the mechanical information to obtain the target foot model.

The executive body can further adjust the bones of the initial foot model through the mechanical information so as to improve the accuracy of the bones of the initial foot model and the actual target foot.

In some optional implementations of some embodiments, the adjusting the initial foot model based on the mechanical information to obtain the target foot model may include:

first, a standard foot model corresponding to the initial foot model is determined based on the mechanical information.

The initial foot model is obtained by the executive body based on the reference foot model and comprises corresponding bone features. In practice, different foot types may have ideal foot type structures, and the execution subject may determine a standard foot model corresponding to the initial foot model in combination with the mechanical information of the target foot. That is, the standard foot model may be the most reasonable model of the target foot. Specifically, the executive body may fine-tune the bones of the initial foot model based on the mechanical information to obtain a standard foot model.

And secondly, generating a target foot model from the initial foot model to the standard foot model.

The standard foot model represents the ideal structure of the target foot, while the current actual structure of the target foot is the corresponding structure of the initial foot model. In order to improve the stress condition of the target foot and the health condition of the foot, the executive body can construct a plurality of target foot models so as to realize the transition from the initial foot model to the standard foot model.

In some optional implementations of some embodiments, the determining a standard foot model corresponding to the initial foot model based on the mechanical information may include:

the method comprises a first step of determining at least one static stress point of the target foot based on the static mechanical information.

The mechanical information includes static mechanical information and dynamic mechanical information. The static mechanical information may include pressure values of a plurality of force-bearing points of the target foot, which are detected when a target person corresponding to the target foot stands on the pressure detection device. The executive body may determine at least one static force point of the target foot from the plurality of force points based on the static mechanical information.

And secondly, drawing a bone motion curve according to the dynamic mechanical information.

The dynamic mechanical information may include pressure values of various force-bearing points detected by the pressure detection device when a target person corresponding to the target foot performs a motion (for example, running, jumping, etc.) on the pressure detection device, and motion trajectory information of the target foot during the motion. The dynamic mechanical information can be obtained jointly through the pressure detection equipment, the image acquisition equipment and the like. For example, the pressure detection device can acquire the pressure values of all stress points of the target foot in the motion process; the image acquisition device can mark the moving track of each position marking point in the at least one position marking point of the target foot in space in the acquired video of the target foot. The position mark points can be arranged at positions corresponding to bones of the target foot. And then the executing body can perform operations such as fitting on the moving track and the like to obtain the motion track information of the target foot. Further, the executive body can draw the bone motion curve through the dynamic mechanical information. The skeletal motion curve may be used to characterize the spatial position change of the bones of the target foot during motion.

And thirdly, adjusting at least one bone difference value parameter of the target foot based on the bone motion curve to obtain at least one bone difference value updating parameter.

As can be seen from the above description, the bone difference parameter is obtained from the three-dimensional reference model of the foot, which is static, so that the bone difference parameter represents the bone characteristics of the target foot in the static state, and cannot represent the bone characteristics of the target foot in motion. To this end, the execution subject may adjust at least one bone difference parameter of the target foot through the obtained bone motion curve to obtain at least one bone difference update parameter. For example, the execution main body may attach a bone motion curve to the corresponding position mark point, guide the motion of the bone in the initial foot model according to the bone motion curve, adjust parameters such as the length and the width of the bone in the initial foot model during the motion process, and further obtain at least one bone difference value update parameter. In this way, the executive body may further optimize the bone parameters in the initial foot model by using the at least one bone difference update parameter, so that the optimized initial foot model conforms to the actual motion process of the target foot as much as possible.

And fourthly, determining a standard foot model corresponding to the target foot according to the at least one static stress point and the at least one bone difference value updating parameter.

In practice, the target foot may be affected by the athletic habits of the target person, the structure of the selected shoe, and the like, so that the target foot gradually suffers from problems such as deformation and the like. For this purpose, the executive body can determine the bone structure of the target foot through the static force bearing points of the target foot and at least one bone difference value updating parameter, and then adjust the force applied to each static force bearing point in a mode of adjusting the bone structure to obtain a standard foot model of the target foot. The standard foot model represents an ideal state of the target foot, so that balanced stress of each static stress point can be realized, and the stress condition and the athletic performance of the target foot are improved.

In some optional implementations of some embodiments, generating the target foot model from the initial foot model to the standard foot model may include:

in a first step, at least one foot adjustment parameter from the initial foot model to a standard foot model is obtained.

The executive body may compare the initial foot model to a standard foot model to obtain at least one parameter adjustment difference between the initial foot model and the standard foot model. The foot adjustment parameters are used for representing the change trend from the initial foot model to the standard foot model.

And a second step of generating at least one target foot submodel from the initial foot model to a standard foot model based on the at least one foot adjustment parameter.

After obtaining the at least one foot adjustment parameter, the execution main body may divide each parameter adjustment difference value of the at least one parameter adjustment difference value into at least one difference value interval. For example, the foot adjustment parameters may be: the first phalanx contracts 1 cm inward (i.e., toward the axial direction of the foot). This corresponds to the case of hallux valgus of the foot, etc. The executive body may divide the foot adjustment parameter into: 0-0.1 cm, 0.1-0.2 cm, 0.2-0.3 cm, 0.9-1.0 cm. Similarly, other foot adjustment parameters may be set to the same or different number of difference intervals as desired. In this way, a target foot submodel may be reconstructed based on the corresponding difference intervals of the plurality of foot adjustment parameters. In this manner, at least one target foot sub-model is derived from the initial foot model to the standard foot model. The target foot submodel may cause the target person's target foot structure to gradually transition from the current three-dimensional model to be processed to the standard foot model.

And 305, generating insole information corresponding to the target foot through the target foot model.

The content of step 305 is the same as that of step 203, and is not described in detail here.

With continued reference to fig. 4, fig. 4 illustrates a flow 400 of some embodiments of a method for generating insole information in accordance with the present disclosure. The method for generating insole information comprises the following steps:

step 401, acquiring a to-be-processed three-dimensional model and mechanical information of a target foot.

Step 402, constructing a target foot model corresponding to the target foot based on the three-dimensional model to be processed and the mechanical information.

The contents of step 401 to step 402 are the same as those of step 201 to step 202, and are not described in detail here.

And 403, generating an insole supporting surface through the target foot model.

In some embodiments, the executive body may generate the insole support surface from the target foot model. Wherein the insole support surface is disposed corresponding to the target foot. For example, the insole support surface generated by the executive body may be a curved structure that conforms to the sole of the target foot model. The insole support surface may be an upper surface of the insole and correspondingly, the lower surface of the insole may be a planar structure.

And 404, determining a supporting part corresponding to each static stress point in the at least one static stress point based on the insole supporting surface.

As can be seen from the above description, the target foot has multiple static force points, and the force experienced at each static force point may be different. In general, when the force applied to the target foot is too great, the structure and health of the target foot may be affected. Therefore, the execution main body can determine the supporting part corresponding to the static stress point on the insole supporting surface, so that the supporting part transmits the force applied to the static stress point to other positions, the stress difference between the static stress point and the non-stress point of the target foot is reduced, and the target foot can be uniformly stressed as much as possible. The shape, size, elasticity, and position of the support part on the insole can be determined according to actual requirements.

Step 405, querying the foot characteristic information of the target foot.

When the three-dimensional model to be processed and the mechanical information of the target foot are obtained, some information of the target person of the target foot cannot be reflected. For example, the target person is a diabetic, and the usage habit of the target foot of the diabetic is different from that of the ordinary person, and a targeted consideration is required. To this end, the executing body may further query the foot characteristic information of the target foot. The foot characteristic information is used for representing the foot type corresponding to the target foot, and the foot type can reflect the characteristics of the target foot used by the target person. For example, the foot type may be a diabetic foot, a disabled foot, and the like.

And 406, determining material information of the insole corresponding to the insole information based on the foot characteristic information and the at least one static stress point.

After the foot characteristic information is determined, the executive body can combine the foot characteristic information and the static stress point to jointly determine the material information of the insole. For example, when the foot characteristic information is the foot of a diabetic patient, and the pressure value of the static stress point is less than the set value, the material information may be sponge. The execution body may select material information from a preset material information library.

In some optional implementations of some embodiments, the determining material information of the insole corresponding to the insole information based on the foot characteristic information and the at least one static force point may include:

and step one, dividing the insoles corresponding to the insole information into at least one insole interval based on the at least one static stress point.

The insole has a large area, encompassing the entire bottom of the target foot. However, the pressure received at different points of static force may be different. In order to better adapt to the stress condition of the target foot, the execution main body can divide the insole corresponding to the insole information into at least one insole interval according to at least one static stress point. Correspondingly, the supporting part can be arranged at the corresponding position in the insole area.

And secondly, determining the material information of the insole section and the structure of the supporting part according to at least one static stress point in the insole section for each insole section in the at least one insole section.

For different insole sections, the executive body needs to determine which material is used in the insole section by considering the number of the static stress points in the insole section. In order to further improve the pressure equalization effect of the target foot, the execution body may also consider the material of the insole section and the like when determining the position of the support part. For this purpose, the structure of the support can also be determined according to the number of static force points. For example, when there is only one static point of force, the face of the support portion contacting the target foot may be arranged directly as a rounded structure; when; when there are a plurality of static force points, the face of the support portion contacting the target foot may be provided as an irregular structure including the plurality of static force points. The supporting part can be arranged in other structures according to actual requirements.

In some optional implementations of some embodiments, the dividing the insole corresponding to the insole information into at least one insole section based on the at least one static force point may include:

the method comprises the following steps that firstly, for a static stress point in at least one static stress point, a pressure interval corresponding to the static stress point is determined according to a preset pressure threshold sequence.

To determine the insole interval, the performing agent may first determine the pressure value for each static force point. The execution body may preset a pressure threshold sequence, the pressure threshold sequence may include a plurality of pressure thresholds, and the plurality of pressure thresholds may sequentially increase in order. When the pressure value of the static force bearing point is between two adjacent pressure threshold values, a pressure interval formed by the two adjacent pressure threshold values can be passed. In particular cases, some pressure values may be exactly equal to the pressure threshold value, and in order to improve the adaptability of the insole region, the pressure region may be formed by the pressure threshold value and the next larger pressure threshold value.

And secondly, dividing the insole into at least one insole section according to at least one pressure section corresponding to the at least one static stress point.

After the pressure interval is determined, the execution main body may divide the insole into at least one insole interval according to the pressure interval.

In some optional implementations of some embodiments, the dividing the insole into at least one insole section according to at least one pressure section corresponding to the at least one static force-receiving point may include:

in a first step, at least one initial interval of the at least one static force point on the insole is determined.

The executive body may first determine an initial interval of each static force point on the insole. The initial interval can be considered as the deformation interval of the static stress point on the insole. For example, the initial interval may be a circular area with a set radius around the static force point.

And secondly, fusing the at least one initial interval based on the pressure interval to obtain at least one pressure fusion interval.

In order to reduce the data processing amount, the execution main body may adopt the same material for the initial interval of the same pressure interval. To this end, the execution body may fuse the plurality of initial intervals, resulting in at least one pressure fusion interval. That is, the above-described fusion operation is used to fuse adjacent identical pressure sections into one section. Each pressure fusion interval contains at least one initial interval.

And thirdly, dividing the insole into at least one insole interval based on the at least one pressure fusion interval.

After the pressure fusion interval is determined, the execution body may divide the insole into at least one insole interval according to at least one pressure fusion interval. In dividing the insole section, a linearization process may be performed on adjacent pressure fusion sections (for example, a boundary line between adjacent pressure fusion sections may be represented by a linear curve, etc.) to divide the entire insole into at least one insole section.

In some optional implementations of some embodiments, the determining the material information of the insole section and the structure of the support part according to at least one static force point in the insole section may include: responding to the number of the static stress points in the insole interval to be 1, and determining the material information of the insole interval according to the pressure values of the static stress points; otherwise, determining the position relation between at least one static stress point, and determining the material information of the insole region and the structure of the supporting part according to the position relation and the pressure value.

When the number of the static stress points in the insole interval is 1, the execution main body can directly determine that the structure of the supporting part is circular, and then determine material information according to the pressure value of the static stress points. When the number of the static force points within the pad section is plural, the executing body may first determine the positional relationship between the plural static force points. The positional relationship may be: the distance between the two static force points is 2 cm. Then, the execution body can determine the material information of the insole section and the structure of the supporting part according to the position relation and the pressure value.

In some optional implementations of some embodiments, the determining a position relationship between the at least one static force-bearing point, and determining the material information of the insole region and the structure of the support portion according to the position relationship and the pressure value may include: and in response to the fact that the maximum distance between the at least one static stress point is smaller than a preset distance threshold value, setting a pressure surface formed by the at least one static stress point as a structure of the supporting part, and determining material information of the insole area.

When the maximum distance between at least one static force bearing point is smaller than the preset distance threshold value, the multiple static force bearing points are close to each other. At this time, the execution body may be configured to set a pressure surface formed by at least one static force-bearing point as a support part, and determine material information of the insole region. For example, if the number of the static force bearing points is 3, the structure of the support part may be a circular structure containing the 3 static force bearing points. The material information can be determined by multiplying the pressure value by a multiple on the basis of 1 static force point.

In some optional implementations of some embodiments, the determining material information of the insole corresponding to the insole information based on the foot characteristic information and the at least one static force point may include: and for the static stress point in the at least one static stress point, determining the material information of the insole according to the stress frequency of the static stress point.

In practice, the force frequencies of the plurality of static force points may be different due to the movement habits of the target person. For example, the static force point of the foot of the sprinter is stressed at a frequency much higher than the static force point of the foot at the rear end, and accordingly, different materials can be used for the front end and the rear end of the foot to reduce the stress condition of the static force point and prolong the service life of the materials. For example, the front end of the foot may be made of a longer-lived material or the like.

With continued reference to fig. 5, fig. 5 illustrates a flow 500 of some embodiments of a method for generating insole information according to the present disclosure. The method for generating insole information comprises the following steps:

step 501, a to-be-processed three-dimensional model and mechanical information of a target foot are obtained.

Step 502, constructing a target foot model corresponding to the target foot based on the three-dimensional model to be processed and the mechanical information.

And 503, generating insole information corresponding to the target foot through the target foot model.

The contents of steps 501 to 503 are the same as those of steps 201 to 203, and are not described again.

And 504, responding to the generated insole information of the target foot, and generating a target shoe model to be processed based on the target foot model and the insole information of the target foot.

And after the execution main body obtains the insole information, generating a target shoe model to be processed by the target foot model and the insole information of the target foot. For example: the execution main body can generate an insole model corresponding to the insole information, and then the insole model and the target foot model are combined to obtain the foot insole model. And then, the execution main body can further add model structures such as soles, vamps and the like to the foot insole model to obtain a target shoe model to be processed.

And 505, displaying operation options corresponding to the target shoe model to be processed.

After the target shoe model to be processed is obtained, the execution main body can display operation options corresponding to the target shoe model to be processed on the display device in signal connection with the execution main body. Wherein the operation options include at least one of: a sole option library, a vamp option library and a shoe type option library. Each of the library of operational options may be selected to determine the various options for the sole, upper, shoe type, and material desired. Therefore, the personalized customization of each content of the target foot, the sole, the vamp and the like is realized.

Step 506, in response to receiving the confirmation signal corresponding to the operation option, generating the target shoe information based on the operation option result corresponding to the confirmation signal.

When the execution main body receives the confirmation signal of the operation options, the execution main body indicates that the user selects the corresponding sole, vamp and shoe type in the operation options. At this time, the execution body may generate target shoe information corresponding to the target foot through the contents selected by the user, and the target foot model and insole information. The target shoe information includes at least one of: target sole information, target vamp information, target shoe type information. Therefore, the target shoe is obtained through the matching of the insole information, the sole, the vamp and the like, and the balanced stress of the target foot and the adaptability of the foot shape are further improved.
