Detailed Description
The present application will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present application more apparent.
It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present application should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present application belongs. The terms "first," "second," and the like, as used in embodiments of the present application, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
For analysis of foot pressure, the method has important significance, for example, the change of the foot pressure distribution can be known, and potential risks caused by the change of the foot pressure are prompted through analysis. Three detection modes are mainly used for detecting foot pressure, including a dynamic detection mode, a static detection mode and a balance degree detection mode. The dynamic detection mode is the detection of the human body in a natural walking state, the static detection mode is the detection of the human body in a two-foot standing state, and the balance degree detection mode is the detection of the human body in a two-foot standing state for a certain time. The dynamic detection mode is closest to the most common foot state of the human body, so that the foot data reliability in the detection mode is optimal.
In the related art, the foot shape of both feet of a user is obtained by the user naturally walking on the plantar detection apparatus. In the process of acquiring a user in a dynamic detection mode, the acquired foot type of the two feet can have the problems that the two feet are unfavorable for visual display and the like. Considering the detection precision and the detection efficiency of the plantar detection device, when the foot type is detected in a dynamic detection mode, as shown in fig. 1, the size of the plantar detection device only supports to keep the foot print information of a single foot when the user walks naturally in one direction, and the foot type to be detected of the double feet can be obtained only by the fact that the user to be detected walks back and forth on the plantar pressure detection device, so that the foot type to be detected of the double feet is more beneficial to acquiring foot data in the real state of the user. The bipedal shape thus obtained has opposite directions and may have overlapping problems. Thus, the display effect on the feet of the feet is poor, and the user experience is poor.
In view of the above, the embodiment of the present application provides a foot-type display method, which adjusts the orientation of the detected foot-type contours (e.g., right foot) to make the orientations of the foot-type contours uniform, and moves at least one of the foot-type contours with the same orientation to avoid overlapping of the foot-type contours with the same orientation, so that the foot-type contours with the same orientation can be displayed in a differentiated manner, thereby facilitating the user (e.g., doctor or patient with foot type detection) to perform the comparative analysis of the foot-type contours.
Fig. 2 shows a flow chart of an exemplary foot-type display method according to an embodiment of the present application.
Before starting the test, a user (e.g., a diabetic or other person desiring to know foot type information, etc.) may first barefoot onto the foot-type test pad 10 as shown in fig. 1. The user then starts to walk naturally until the user reaches the plantar pressure detection apparatus 11, i.e., starts to acquire foot type data of the user, and the like. The plantar pressure detection device is a device capable of detecting a pressure value, has a preset coordinate data matrix, and is capable of outputting an original coordinate data matrix. Each coordinate point in the original coordinate data matrix has corresponding pressure value, abscissa and ordinate information and the like.
As shown in fig. 2, an exemplary foot-type display method according to an embodiment of the present application may include:
s100, acquiring bipedal foot type data, wherein the bipedal foot type data at least comprises a coordinate data matrix of foot type outlines. Wherein the foot profile comprises a first foot profile and a second foot profile. The first foot-shaped profile and the second foot-shaped profile are obtained in sequence, namely, are obtained at different time points respectively. Wherein, as shown in fig. 3, the first foot profile (e.g., left foot profile) may be oriented in a first direction and the second foot profile (e.g., right foot profile) may be oriented in a second direction, e.g., opposite the first direction.
And S200, rotating the second foot-shaped profile according to the coordinate data matrix of the foot-shaped profile so as to enable the foot-shaped profile to face the first direction. The resulting foot profile may be as shown in fig. 4.
And S300, moving at least one of the first foot-type contour and the second foot-type contour according to the coordinate data matrix of the first foot-type contour and the coordinate data matrix of the second foot-type contour so as to enable the first foot-type contour and the second foot-type contour to be displayed in a distinguishing mode.

In the original coordinate data matrix, each coordinate point may include abscissa data and ordinate data, and corresponds to a specific pressure value respectively. The foot profile can then be derived from the pressure values. Specifically, the coordinate data matrix of the foot-shaped profile can be obtained by filtering coordinate points with the pressure value of 0 and reserving coordinate points with the pressure value of other than 0. The coordinate data matrix of the foot profile comprises abscissa data, ordinate data and pressure value data.
In some embodiments, the profile data of the corresponding single foot may be obtained by fitting coordinate points with a pressure value other than 0 in the original coordinate data matrix acquired from the start of landing the heel of the single foot to the completion of leaving the sole of the foot. For example, the fitting may be performed on the pressure value data about 20 times, and the maximum pressure value in the collected pressure value data about 20 times may be traversed for each coordinate point, and the maximum pressure value may be used as the fitting pressure value data of the coordinate point, and the fitting pressure value data of the coordinate point may be used as the pressure value data of the corresponding coordinate point in the coordinate data matrix of the foot profile. In this way, the coordinate data matrix of the foot-shaped profile can be obtained more accurately.
In some embodiments, for the case that the obtained foot profile of the single foot is an incomplete foot profile (for example, a certain part is missing), a prompt message may be output to remind that the foot profile data needs to be acquired again.
In some embodiments, in response to determining that the foot profiles of the same single foot obtained multiple times are all incomplete foot profiles, no prompt message is output, and the incomplete foot profile is determined to be the corresponding first foot profile or second foot profile.

And calculating to obtain the ordinate of the rotated coordinate point of the second foot-type contour according to the ordinate minimum value of the original coordinate data matrix and the ordinate data of the coordinate point of the second foot-type contour.
Then, according to the calculated abscissa and ordinate of the coordinate point of the rotated second foot-shaped contour, the second foot-shaped contour is rotated to the positions of the abscissa and ordinate of the coordinate point of the rotated second foot-shaped contour, namely, 180-degree rotation of the orientation of the second foot-shaped contour is realized, the second foot-shaped contour can be accurately rotated from the second direction to the first direction, and the problems of inaccurate rotation, offset and the like are avoided.

Through the calculation, a coordinate point of the second foot-shaped outline after 180 degrees of rotation is obtained accurately.
In step S300, after the second foot-shaped contour rotates, there may be cases where the coordinate points in the coordinate data matrix of the first foot-shaped contour overlap with the coordinate points in the coordinate data matrix of the second foot-shaped contour after rotation and/or are inconsistent in vertical direction, and at this time, by moving the first foot-shaped contour or the second foot-shaped contour, the first foot-shaped contour and the second foot-shaped contour can be displayed in a differentiated manner.
In some of these embodiments, a first one of the foot-shaped contours and a rotated second foot-shaped contour, the first foot-shaped contour having a minimum ordinate that is a first ordinate; the minimum ordinate of the rotated second foot-type outline is the second ordinate; the first ordinate is different from the second ordinate:

and calculating the difference between the first ordinate and the second ordinate, calculating the sum of the ordinate of the coordinate point of the rotated second foot-type contour and the difference, obtaining a display ordinate matrix of the rotated second foot-type contour, and updating the coordinate data matrix. And then, each coordinate point in the second foot-type profile is moved to the position of the updated coordinate data matrix, so that the rotated second foot-type profile is identical to the minimum ordinate of the first foot-type profile data. The consistency of the vertical direction of the second foot-shaped profile and the first foot-shaped profile is realized, the two foot-shaped profiles detected in a dynamic detection mode can be consistent in the vertical direction, the two foot-shaped profiles can be displayed more intuitively and accurately, and a user can compare and analyze the two feet conveniently.
