Embodiment 1

[0051] refer to Figure 1-6 As shown, the embodiment of the present application provides a method for plantar correction based on lower limb assessment and gait analysis, the method includes the following steps:

[0052] S1: Receive RGB-D video data and plantar pressure data of human lower limbs in real time during gait movement.

[0053] In this step, an RGB-D camera is used to collect the RGB-D video data of the gait movement of the lower limbs in real time, and upload it to the terminal service system. Wherein, RGB-D video data includes but not limited to time, Depth (depth) image, RGB (color) image. The pressure treadmill is used to collect the plantar pressure data of lower limb gait movement in real time and upload it to the terminal service system. Plantar pressure data include but not limited to gait time, gait cycle, gait phase, pressure value, landing position, etc. Gait refers to the posture and behavior characteristics of the human body when walking. The human b...

Embodiment 2

[0074] The embodiment of the present application provides a plantar correction system based on lower limb assessment and gait analysis, using the method of embodiment 1, the system includes: data transmission module 100, data calibration module 200, mask extraction module 300, coordinate construction module 400 , position extraction module 500 , included angle calculation module 600 , and pressure adjustment module 700 .

[0075] The data transmission module 100 is configured to receive RGB-D video data and plantar pressure data of human lower limbs during gait movement in real time.

[0076] The data calibration module 200 is configured to align the Depth image and the RGB image in the synchronized RGB-D video data based on the time sequence using the frequency synchronized RGB-D video data and the plantar pressure data. Further, the sampling frequency of the preset pressure treadmill is H r , the sampling frequency of the RGB-D camera is H p , where H r >H p , set the ...

Embodiment 3

[0089] In one embodiment, the embodiment of the present application provides the application of the first embodiment, using the orthopedic insole made by the plantar correction method based on lower limb assessment and gait analysis in the first embodiment.

[0090] In another embodiment, the embodiment of the present application provides the application of the first embodiment, and the orthopedic shoes made by using the method of plantar correction based on lower limb assessment and gait analysis in the first embodiment.

Abstract

The invention discloses a plantar correction method and system based on lower limb evaluation and gait analysis and application of the method and the system. The plantar correction method comprises the steps: S1, receiving RGB-D video data and plantar pressure data; S2, synchronizing the time sequence of the RGB-D video data and the time sequence of the plantar pressure data, and aligning a Depth image and an RGB image; S3, segmenting a human body mask; S4, extracting a plurality of feature key points of the lower limb part; S5, acquiring spatial positions of the feature key points; S6, calculating an included angle, and obtaining a curve of each angle of the lower limb changing along with the gait cycle; and S7, performing gait analysis and lower limb evaluation, acquiring gait characteristics and human body lower limb conditions, increasing pressure on corresponding parts of the foot sole during human body movement according to the lower limb conditions, and designing and manufacturing a plantar orthopedic device. The plantar orthopedic device is designed and manufactured through the gait analysis and lower limb evaluation so as to prevent the lower limbs from being abnormal after the plantar exerts abnormal force, and the purpose of protecting the lower limbs is achieved after the plantar exertion recovers to the normal range by adjusting the distribution range of the plantar exertion.

Description

technical field [0001] The invention relates to the technical field of sports medicine, in particular to a plantar correction method, system and application thereof based on lower limb assessment and gait analysis. Background technique [0002] Research has found that in lower limb rehabilitation problems, there are many reasons for lower limb dysfunction, including sports injuries, nerve injuries, etc. Due to the inability to receive effective rehabilitation treatment, sequelae are left behind. However, the current status of lower extremity rehabilitation in the medical system is as follows: 1. The number of rehabilitation physicians is limited, resulting in an imbalance between supply and demand; 2. The existing rehabilitation equipment in the hospital is high in cost and poor in portability, and the cost of time, space and money is relatively high; 3. Patients lack personalized guidance for active rehabilitation training. Therefore, it is necessary to provide rehabilitat...
