Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of the invention and do not delimit the embodiments. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.
Fig. 1 is a flowchart of a method for determining an internal model of a shoe body based on foot dynamic data according to an embodiment of the present invention, which can be implemented by shoe body design software, and specifically includes the following steps:
step S101, obtaining a foot dynamic image of a user, wherein the foot dynamic image comprises a plurality of continuous multi-frame images under different preset postures.
In one embodiment, the different preset postures may be postures of the user when walking, that is, the feet normally walk, and include continuously photographed images of the foot landing posture, the foot leaving posture, and then the foot landing posture, which are taken as the foot moving images. Specifically, the shooting process includes a plurality of different shooting angles, such as the shooting angles of the front, the side and the back of the foot, so as to obtain the dynamic image of the foot.
In one embodiment, the foot motion image is an image of a foot of a bare foot.
And S102, determining the dynamic foot deviation amplitude and the mobile contact parameter according to the dynamic foot image, and determining the adjusting part and the adjusting scale in the shoe body model according to the dynamic foot deviation amplitude and the mobile contact parameter.
In one embodiment, after the foot dynamic image is acquired, the corresponding foot dynamic offset amplitude and the moving contact parameter are determined. Specifically, it may be: and carrying out target object identification on the dynamic foot image, and determining an image with the maximum offset degree, wherein the offset degree comprises the integral offset and the local part offset of the foot. The entire foot deviation takes the entire foot as a recognition target, and the local part deviation takes the local part (such as toe and joint) of the foot as a recognition target.
Specifically, the identification process may be: identifying and obtaining a reference object position in the foot dynamic image based on a plurality of pre-input reference template images under different angles; and determining the image with the maximum offset degree according to the position of the reference object. The reference template image is an image obtained when all the foot parts are landed, based on the position where the set foot part is in the reference position, for example, the position where all the foot areas are landed. The degree of the deviation may be an image corresponding to a position where the foot is farthest from the reference position.
Optionally, when determining the moving contact parameter, the following may be performed: identifying a contact point of a target object in the dynamic foot image, generating a contact track based on the contact points in a plurality of different images, wherein the contact track comprises contact areas of the target object under different time sequences, and determining a mobile contact parameter according to the contact track. The contact points refer to points in the image when the feet contact the ground, and in the multiple different images, the positions of the feet contacting the ground are different, such as all contact, all lift-off, partial contact in the processes of landing and lift-off, and optionally, when the contact points refer to partial contact, the contact points marked in the corresponding image. Illustratively, the contact point is the lateral side of the foot when the lateral side of the foot preferentially lands, and the contact point area gradually increases until the entire land is landed when the land is gradually landed. The dynamic change of the contact point is recorded, i.e. the contact trajectory. Alternatively, the contact locus may be a contact area composed of contact points, i.e., an area of a maximum range surrounded by the contact points. Namely, the process of gradually increasing the area from the initial foot landing, namely, the above-mentioned contact trajectory generation process.
Optionally, the determining a moving contact parameter according to the contact trajectory includes: respectively determining the weight of each preset contact part according to the contact track; and calibrating the mobile contact parameters according to the weight of the preset contact part. In one embodiment, the weight of the preset contact position is determined according to different contact tracks, for example, the weight can be set to 1 to 3, and the higher the weight of the position preferentially contacting the ground, for example, the contact tracks are: the weight of the foot part can be sequentially set as the foot part rear end 3, the foot part middle 2 and the foot part front end 1; if the contact tracks are: the lateral side of foot, the middle of foot, and the medial side of foot can be set as lateral side of foot 3, middle of foot 2, and medial side of foot 1 in sequence. The contact parameters are obtained by weight calculation, the weights are distributed only according to the contact sequence, and the final calculation mode of the mobile contact parameters also comprises the contact time, for example, the contact time is multiplied by the weights of the corresponding parts to finally obtain the mobile contact parameters of each preset contact part.
In one embodiment, after determining the moving contact parameter and the dynamic foot deflection amplitude, an adjustment location within the shoe body model is determined based thereon. Optionally, the shoe body model may be a three-dimensional model that is preset to generate and display, each of the internal part models and the external part model is a default initial value during initialization, and the initial value of the model is subsequently adjusted based on the moving contact parameter and the dynamic foot offset amplitude, that is, the adjustment of the internal model.
Optionally, the determining an adjustment position inside the shoe model according to the dynamic foot offset amplitude and the moving contact parameter includes: determining a corresponding foot area type under the dynamic foot offset amplitude, if the foot area type is an overall type, determining a preset adjusting part corresponding to the overall type as a first type of adjusting part, and if the foot area type is a local type, determining a local type of foot area as a first type of adjusting part; and defining the curved surface adjusting range of the inner model of the shoe body according to the mobile contact parameters, and determining the curved surface adjusting range as a second type of adjusting part.
If the type of the foot region is the integral type, that is, model adjustment needs to be performed based on the whole foot, at this time, a preset adjustment part corresponding to the integral type is determined as a first type adjustment part. The preset adjusting parts corresponding to the whole type can be a heel part and a forefoot part as an example; and if the type of the foot area is a local type, determining the foot area of the local type as a first type of adjustment part, and if the local part is a front toe, taking the front toe area as the first type of adjustment part. The specific adjustment modes of the first type of adjustment part and the second adjustment part are different, so that two types of differentiation are performed, in the specific determination process of the first type of adjustment part, the differentiation of the determination modes of the adjustment parts which are different under the two conditions of whole and local is performed, and one type adopts a preset part and the other type is determined according to the actual local part.
And aiming at the determination of the second type of adjustment part, the curved surface adjustment range of the internal model of the shoe body is defined according to the mobile contact parameters, and the defined range is determined as the second type of adjustment part. Optionally, the curved surface range formed by the areas with the moving contact parameters larger than the preset value is determined as the second type of adjustment location according to the moving contact parameters of each location calculated based on the weight and the contact time. For example, the second type of adjustment location is defined as the area outside the sole of the foot.
Optionally, the specific adjustment scale is determined, and for the first type of adjustment part, the larger the dynamic offset amplitude of the foot is, the larger the adjustment scale is, and vice versa, the smaller the adjustment scale is; for the second type of adjustment part, the larger the calculated moving contact parameter is, the larger the adjustment scale is, and vice versa.
Step S103, under the condition that the number of the adjusting parts is multiple, adjusting parameter range intervals corresponding to each adjusting part are respectively obtained, the adjusting parts are adjusted in the adjusting parameter range intervals in combination with the adjusting scale to generate adjusting areas, and the shoe body internal model is obtained on the basis of the generated adjusting areas.
In one embodiment, if a plurality of portions to be adjusted are determined, an adjustment parameter range interval corresponding to each adjustment portion is respectively obtained, and the adjustment portions are adjusted in the adjustment parameter range intervals by combining the adjustment scale to generate adjustment regions. The adjustment parameter ranges of different adjustment parts are different, and some adjustment ranges are large and some are small. In the specific adjusting process, the adjustment is carried out in the correspondingly set adjusting range interval by combining the adjusting scale. If the interval of one adjusting part is 5-10mm, and the interval of the other adjusting part is 5-20mm, the adjusting values are 7.5mm and 12.5mm respectively for the same adjusting scale, if the adjusting scale is medium, and here, the mode that the average value of the interval range is determined as the adjusting value is used for the medium adjusting scale. If the adjustment scale is high, the corresponding adjustment values are 10mm and 20mm, respectively.
In one embodiment, for the first type of adjusting part, the adjusting mode with different concave sizes is adopted; and aiming at the second type of adjusting part, the adjusting mode with different curved surface radians is adopted. Of course, the adjustment may be performed simultaneously without dividing the types. The above description is merely preferred.
Specifically, if the determined adjustment value is 5mm, the concave size and the curved surface radian of the corresponding adjustment part are adjusted, and if the concave size is 5mm, the curved surface radian is increased by 5mm, and the like. Illustratively, if the outer side of the foot is determined to be an adjusting part, correspondingly determining the adjusting value to be 10mm according to the interval range, and adjusting the radian of the curved surface so as to gradually increase the radian of the position of the outer side of the foot corresponding to the internal model of the shoe body to 10mm; if the toe area is determined as the adjusting part and the adjusting value is 5mm, the model in the area is recessed by 5mm.
According to the above, by acquiring the foot dynamic image of the user, the foot dynamic image comprises a plurality of continuous multi-frame images in different preset postures; determining the foot dynamic offset amplitude and the moving contact parameter according to the foot dynamic image; determining an adjusting part and an adjusting scale in the shoe body model according to the dynamic foot deviation amplitude and the moving contact parameters; under the condition that the number of the adjusting parts is multiple, respectively acquiring an adjusting parameter range interval corresponding to each adjusting part, and adjusting the adjusting parts in combination with the adjusting scale in the adjusting parameter range interval to generate an adjusting area; based on a plurality of that generate the adjustment region obtains shoes internal model, has solved prior art, when carrying out shoes body model design, and the design is static single relatively, lacks the problem of reasonable dynamic parameter's consideration, has promoted the rationality of shoes body model design, accords with user's demand more, and the design of shoes body model is more comprehensive, and the shoes body model of design accords with user's expectation more, and the effect is better.
